D.I.Y. the long-awaited amp integration harness by Whiterice!

[emerylu]

oops; I think I just realized that the Crutchfield harnesses are not made by Metra...the search on their site is bunk and I didn't read carefully!

[emerylu]

oh and one more thing, in the first first pic; isn't Red supposed to be for Right and White/Black for Left?

[Z1 Performance]

Just so people are aware, there are 2 wires that are blue with silver stripes...

One is on the radio harness that will plug into your Metra harness...the other is left dangling when you remove the factory radio.

The light blue wire w/ silver strip on the harness left dangling is the amp turn on wire. I found this out the hard way after giving 12V to the wrong wire...which ended up being a front speaker wire. Afterwards, the front channels do NOT work and I'm assuming I fried the front channels of the factory amp.

PLEASE test-everything before making connections!!! The rears sound ok though haha

I have a nice Alpine 40x4 channel amp to put in and I will re-use the crutchfield OEM amp bypass harness to install it and utilize the factory speaker wiring.

when i had my home boy do this at cuircut city wen installing my pioneer doubled in he did this aswell its just converting all the speaker lines to rca's so u can just plug um right into the back of the head unit

[20civic07]

i connected everything, and checked the connections with my multimeter.. one of my connections had a resistance of something like 40 ohms.. this wont affect anything with sound quality will it? also, the RCA wires that i spliced were REALLY thin. about 1/3 or 1/2 that of the metra harness.. is this normal? thanks!

[jermine]

help pls.. i just got a EX coupe 03 with the factory stereo cd player and i bought an amps and subs, need help to figure out how to install and where i can find the remote power antenna wire to power on the amps and output RCA from the stereo? detailed info in the easiest way to install it would be great.. thanks

how did you do that? i'm not trying to say anything on you knowledge on this, but before power was even hooked up to the unit you should have realized that you had 2 wires going to the same wire.

maybe i'm not understanding what you did but it sounds like you did this:
from aftermarket radio-amp turn on wire ( always blue to me)
then you hooked that wire up to the Right Rear = Blue(should have tapped it into the light blue one)
but if that was case your rca cables are plugged in backwards and should have blown your rear channel....
so is what i am describing what you did?
and is there two diffrent plugs one that the metra plus into and the other that usually isnt used but you only tap one wire into it(the amp turn on to that one blue wire) or is it all in the same harness?

im just woundering cause im about to install nav on my car and dont want to do what you did or if i did i would throw my stock unit back in and bring it in for service and say it just went out.

[hockeymutt]

i am in no way trying to be a smart ass i'm just asking so i dont do this to my car.. sorry if it sounds like i am. that is that farthest thing from what i'm try to say.... i'm just asking for help.

[hockeymutt]

i think this what is going on with this harness confussion i am having with what harness i tap the wire to turn the amp on with.

tap it off the cig lighter iv ran numerous things off that positive wire in my rsx worked like a charm...

I, too, am having this issue. When the key is turned to ACC II, there is static-buzzing coming from the driverside front speaker (seems like just the tweeter).

I checked my solder job - and resoldered a different RCA cable to that speaker - still no good. Being that this only happens when the key is turned to ACC II it would almost imply that there is a ground issue (ACC II turnes on other mechanisms and these mechanisms may share the same ground). The only problem I have with this theory is that it only seems to be happening to one speaker. If there were a ground loop issue it seems that it would effect all the speakers I may try to ground everything out at a screw on the metal chassis instead of the ground on the factory harness. Still, it would seem that this issue would be present in all of the speakers and not just the tweeter of the driver side front speaker.

This is obviously a common theme. Has anyone found a fix for this (without using the amp bypass or aftermarket amp)? I would say that there may be a bridged connection in the metra harness, but the buzzing would be present in the ACC I position as well.

Before you ask, YES - my wiring is correct (possible groundloop issue not withstanding). This is seriously pissing me off!! If anyone could save me from spending more money, I would greatly appreciate it!!!!

yea, i called up metra and they inculde in there instructions how to use the factory amp so i asked them if i should wire up rca's or just wire it normal and just run a wire to the blue wire to turn on the amp and they said its better just to run it normal and just tap the wire. I also talked to my dad who used to be a nuclear engineer for the navy and he said just to do it normal as well. I fix electrical systems on helicopters for the coast guard and it sounds like the rca are causing problem with this being the most of the are shielded pairs. but my question is to you tap the blue wire with the amp turn on wire or the acc red wire. cause if you tapped it with the red wire cause that could be the problem. if you tapped it with the red wire either use the amp/power antenna wire or go to the cig lighter and use the positive wire off that.

Much appreciated!

I'm heading down to circuit city tomorrow morning to pick up 2 Tsunami Ground Loop Isolators. I'm willing to throw down $30 to have clean sound!

[NHBPBiznitch]

always worht a lil extra for the sound for show, this is good thread, def going to do this too

Instead told me to use a different one... (Honda Integration Adapter Bypasses the factory amplifier in select 2006-up Hondas at Crutchfield.com)

I think I want to use the Amp integration method (unless others have had better results with bypass? -- I've been reading mostly in 8thcivic and avic411). Are the radio harnesses different on '08?

Also; possibly off topic to this thread, but is there a harness for the other 20-pin connector...I know it's only two pins (Amp control and Remote Control [REMC]) that I need, but just curious.

Thanks!

which one do i need for the SUB and AMP?

+ after market

[emerylu]

My problem is slightly different. Maybe someone can help? The buzz / hum is really quiet and only happens when the headlights are on and the amp is powered (if I push the dimmer all the way up or turn off the headlights, then the buzz goes away).

If I unplug the control to the factory amp the buzz goes away. I've tried unplugging all the preout RCAs and still get the buzz as long as the amp control and headlights are on at the same time.

[joon joon]

so i made my harness.. here are some pics

[joon joon]

pretty easy to make.. if anyone is interested i guess i could start making these things.. i'm thinking maybe 30shipped or something around there if anyone is interested..
