07 Full audio system install (updated 4-8-07)

Ok I need to give major credit do xtv-sidecar's DIY. Thanx man it helped me a TON. I have a few things to contribute. Today was DAY 1 of my install project on my 2007 civic.

Here are the parts I ordered.

Crutchfield Part List
Honda Civic 06-Up Amplifier Bypass for Premium Sound (Item # 120701727)
Honda Antenna Adapter Motorola Male to OEM Female (Item # 12040HD10)
PAC SWI-X Steering Wheel Radio Control Interface (Item # 127SWIX)

In addition to the amp bypass you'll also need a radio wiring harness if you don't want to tap into your factory harness. Do a search for Scosche HA10B or a Metra 1722. I'm using the scosche in my install.

Honda Part List
Center Panel Gray (Part # 77250-SNA-A01ZA)/Center Panel Tan (Part # 77250-SNA-A01ZB)
Passenger Side Radio Bracket (Part # 77255-SNA-A00)
Driver Side Radio Bracket (Part #77256-SNA-A00)
DIN Pocket (Part # 08B60-SCV-100)

First a stock photo of the HU.


First off disconnect the negative connector on the battery. (10mm socket)


Then start at the bottom left corner of the steering column panel and pry towards you, (move the steering column panel as far up and out as you can). Once you get the first clip off off your set the rest.




This is the back of the under steering wheel column panel.

Using a flat head screwdriver pop out the panel under the stock radio near the shifter.



Ok the next part is a PAIN IN THE ASS!!!!!!!!. At first I used a philips screwdriver but then I realized using a 9mm socket worked better. There are 2 screws at the top of the front console pocket hole. You have to get on your hands and knees and manuever you head so you can see what I'm talking about. There are 2 screws use a socket don't use a screwdriver as mine were really hard to get out and you don't have a lot of room to work with.

Underneath the steering column there is another screw take that out as well. Now your ready to take the drivers side dash off. Again start from the bottom left once you pop the first clip your set for the rest. Don't pull it, give quick shark pulls till each clip gives way.

Make sure you disconnect the side mirror harnesses.

Now your ready to pull off the audio console. Same thing start bottom left and work your way up and around. You'll end up disconnecting 5 harnesses I believe, 3 of which are in the radio itself. Tuck these 2 wires away for later.


Now put your 2 audio consoles side by side and remake the new console with the old parts.

The vent will be the LAST thing you put on because you need to have access to the screws for your new radio bracket. Be carefull taking the lightrings off. I used a flat head screwdriver. First put in the AC/Heating component.

But be gentle, turn your rings as far to the left as you can so it will be easy to allign to the other console.


This is the full assembled audio console - the aftermarket radio.


Put your radio in with your new brackets and your DIN.


This is my Alpine IVA-D100 DVD player in the new audio console.


Now we need to find the factory amp and unplug the damn thing. It's located right under center console below the dash pocket.

I'm sure it's the same basic removal instructions for a stick, start by prying the area around the shift up and out which will release the center console. Since your battery is disconnected there is a small tab that if you press it in with a key or w/e it will let you shift down or move the shifter out of the way. I'll take pics of this tomorrow for everyone.

You can see your factory amp disconnect the larger harness on the right. Leave this unplugged.




Now since I plan on putting a sub in the trunk I need to get a power wire from the battery to the trunk. I looked for a long time to find the best position to drill through the fire wall. Pull up the carpet on the passenger side. Near the center console you will see a hollow pipe looking thing (not sure what this does but you can pull it off it goes back in easily by squeezing the sides and shoving it back through the hole it goes to the outside of the car) right next to this piece of piping drill a hole straight through the first piece of metal and then through the fire wall. I had to go to home depot and get a 1/2 gauge titanium bit and it went through very easily (price was $14.95 on the bit)


Solder your wires for your speakers. Or cap them w/e you choose.


Pull the very back of the center console off, should come off easily if you removed the 2 screws on the inside where the CD holder is. This will allow easy access to the carpeting.


Fish the power wire under the carpet.


Now pull up the back seat, there are 2 clips on on either side of the seat locking it into place. A good tug will release the clips. They're metal so don't worry you won't break them. Fish the wire under the seat.


After fishing the power past the back seat, lower you're back seat using the trunk seat release. Finally pull the wire through to the trunk.


Remove the trunk latch panel and take out the carpet panel covering the spare tire.

You will see a nice set of grounded wires perfect for you subwoofer or w/e use you have to ground your other wire.


It's a 10mm socket to remove the bolt.


Run your ground wire to where your amp will be I ran mine along the sides of behind the carpetting




Connect your amp and box and get that thing in the trunk and make your appropriate connections.


Use a votage meter to test your harness some Scosche HA10B have their power and grounds backwards. Be careful the wires.

Connect up your radio using your manufacturer instructions.


Make sure it works...

Now it's time to hide the mess of wires all over your car.


I hid everything under the the factory amp. It requires some kama sutra skills and some patience but don't half ass it. This step is really the most important of all as people will notice lol.

Put your dash back together and marvel at your job well done.






I have to take a break, I'm tired and it's easter and I'm missing some screws, damn cat -.-.

When it warms up I'll do the PAC programming for video bypass and steering wheel controlls :).

ok so i did the amp by pass and it sounds 100 times better. thanks for every body's help
This weekend pending the weather, I will be installing the alpine video bypass, and the steering wheel IR controls. I'll upload after it's complete, I also want to run a switch to turn on/off the subs, but I'm having a hard time getting a remote wire to a fuse, any suggestions? Ideally -> remote from sunroof fuse -> switch
Alright i'm a bit confused and just wanted to clarify. The amp bypass, Item #120701727 on crutchfield, essentially takes the stock speaker wiring that leads to the sub/rear speakers/front speakers/tweeters, and allows you to hook them up to an aftermarket headunit...is this correct?

In other words the wiring from the factory goes: Stock Deck to Stock Amp to Stock Speakers

And this amp bypass changes it to: Aftermarket HU to stock speakers

Did I get all that correct?
Yes basically.

Wiring with stock radio.

HU---Stock amp---speakers

Wiring with aftermarket radio

HU---radio harness---amp bypass---speakers

With the amp bypass your just plugging in a harness into the speakers so that you can preserve the speaker wires. Then the radio harness you pretty much just use power, ground, and remote.


And of course the weather didn't cooperate with me and it rained the whole time. -.-

:eek:hsnap: xxfrozen you have the absolutely best guide in doing a full audio system install. This is great!!!! thanks dude for an awesome write up.
I do have a question tho Basicly 3 harness are required the amp bypass ant adaptor and radio harness, now the amp bypass is the solution to deliver the speaker wiring directly to the aftermarket HU, And the radio harness is the only thing im thinking about .... the radio harness only purpose is to deliver power? or does it continue the path to delivering the signal of the speakers?
again thanks for great write up :thumb:

also these harness are for those that dont want to splice their wiring but i just thought of this if i were to drag high end speaker wire from speakers to aftermarket amp woudnt it sound alot better? or is it just pure wasting time trying to drago wires across the entire car?(kicker monster etc) reason why i say this is because im upgrading everything in the sound system (minus the tweets) i got kicker ks 6 1/2 for front and rear kicker zx1500.1 zx850.4 06ds12l52 kicker O guage kit and scosche dash kit, the only thing im missing is my avic-z2 or D3 (due to the bypass) and those harness xxfrozen what you think should i just use the exisiting wiring and go ahead and order the bypass harness (radio harness and ant adaptor came in the dash kit) or should i just run new wiring and what not?

gus yes, the 3 harnesses you mentioned are correct, the radio harness provides 3 things, power ground remote, you dont use any more wires than those 3 i just mentioned, if you want to thing about the amp bypass, think of it as just extending all the speaker wire leads directly into your aftermark head unit. I'll try to take some more pictures for you guys seeing as there is still some confusion.

Your second question concerning the quality of the sound, YES, by all means run your own speaker wire. This is just a temporary set up for me as I don't want to drop a ton of money on an audio system at this time; but yes once I purchase some aftermarket speakers, I will be running all new wiring.
is the ACC ignition wire what turns on the head unit when you turn on the car?
yes (my post was too short and had to add more text)
Any wiring guides for us sedan owners? I can figure out speaker wires when I replace stock, but will have to voltage test form remote :(

Hmm well I guess i can't edit the first post. But I did some work today, not too much but enough.

Powering up the woofers

I chose to to use a simple on/off switch for the subwoofers instead of them always being on, somtimes I just want to enjoy music without the woofers and it helps if you want to listen to music in the winter during those cold days, so you don't crack to woofer. Anyway here we go.

First off, I'm sure there is a better way to do this but connect a power wire from your red wire on your radio harness and run it to the power lead on your switch. Take to ground and remote wires from the sub amp and run those to the switch as well, connecting the ground to ground lead on the switch and the remote, to the load lead on the switch. You can get a switch at radio shack or pep boys, radio shack was cheaper I think though.





Turn the **** on make sure it works. Now what to do about the power wire coming from the battery. Radioshack also has some black loomz that I used to cover the wire. I don't like the colored loomz just because they look blah >_>



My car's getting really dirty gotta was it :)

More to come, but sounds wise it's a ton better, I can turn the bass down and turn up the subs now, to turn it up louder, I can't wait to get those crappy stock speakers out of this car.

07 Civic Coupe aftermarket sub installation???

OK, I have a question for all of you audio experts out there. I am in the process of installing an aftermarket amp & sub in my 07 civic coupe. I want to keep the vehicle as stock as possible in case I decide to trade it in a few years down the road. Because of this I have decided to keep the factory head unit. My plan as of right now is to simply unplug the factory subwoofer that is part of the "premium audio system." I will then splice into those leads and run them to the speaker level inputs(or high level inputs) of my aftermarket amp. With this setup I believe I will still be able to control the bass levels with my factory head unit. I am not to familiar with the speaker level inputs, but it sounds to good to be true! What are the advantages/disadvantages of the speaker level inputs? Is it going to be an issue that my speaker level inputs into my aftermarket amplifier are coming from the stock premium audio amp? Is this setup going to work at all? I would appreciate any feedback and/or advice that you all can provide. It is much appreciated! I am going to list the aftermarket components that I plan on installing below. Thanks!

(1) Kicker ZX400.1 Mono subwoofer amplifier 220 watts RMS x 1 at 4 ohms
(1) Polk/Momo MM 2104 10" 4-ohm Component Subwoofer
(1) Q-Logic QLH-.6510SS Single 10" Hatch/Trunk Sealed Box-Vol=.65 cubic

I think it's possible but I don't want to give you bad information, Just remember the sub is being powered by an amp so it will be running from amp to another amp to your subs. The sound might be distorted or it may not work at all. I've never tried this but I have done somethig similar in which I took the rear speakers and tapped the leads to RCA's and ran those to the sub amplifier. I was then able to control the bass using the factory amp.

found this in the other thread, sounds like what you want to do hook
Do you know where the factory amp is, so i can bypass the speaker wires there since it would be easiest?
Go back and read my DIY, the amp is under the shifter panel, and what you just asked is exactly what I did.

My Alpine DVD player needs sent in for service again. So I'm gonna sell it on ebay, I've had way to many problems with this thing, I'm getting a Pioneer AVH-5900DVD, I'll make a livejournal and post a more detailed DIY there. I'll post the link when my radio arrives.

NOTE TO ADMINS - Allow us to EDIT posts again.
and just to let ppl know if im not mistaken the factory amp is not in the same spot, in the center console, in the sedens only in coupes. They r i believe under one of the front seats in the sedans.... i gotta get my audio started/finished. Im still gettin the gear and parts. How much did the dash panel, and harnesses all cost u? They look like they get pricey just to install a h/u....
The sedans don't have subwoofers - their 6 speakers are powered by the stock head unit. My 07 EX Sedan has "160 watt sound system" where the EX Coupe has "350 watt sound system"

The amp bypass notes don't apply to the sedans.

(right?)
i believe the si sedan does have a sub......
