07 Full audio system install (updated as I have time)

[OooskilzooO]

ok so i did the amp by pass and it sounds 100 times better. thanks for every body's help

[xxfrozen]

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?

[xxfrozen]

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. -.-

cool. thx

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

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?

[xxfrozen]

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.

[yourfavoriteicecreamman]

is the ACC ignition wire what turns on the head unit when you turn on the car?

[xxfrozen]

yes (my post was too short and had to add more text)

[Kid Red]

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.

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.

DIY: Installing Aftermarket Subs w/ Stock HU ( and Premium Sound System)

found this in the other thread, sounds like what you want to do hook

[jimjaime]

Do you know where the factory amp is, so i can bypass the speaker wires there since it would be easiest?

[xxfrozen]

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....

[rwburnett]

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?)

[HTX]

i believe the si sedan does have a sub......
