love your post dude! i had people cut the stock harness because theyre impatient/excited to get a new stereo and try to hook it up themselves. and i wanna slap em. but then i just charge them more! tehe! but ya most times when u order a new stereo like from sonicelectronix.com, the harness is free anyway. just do some research before u buy a new stereo. its not hard. and worth it.

i have a 2003 impala 9c1. all the chimes were disabled when i got the car. and there was so much extra wire laying around in that car it was ridiculous. a year later i still havent gotten all the wire out.

but since its a 2003. chevy did something wrong somewhere in there wiring. because in order for an aftermarket stereo to work. u have to run a wire from the red wire on the aftermarket to a fuse spot that turns on with the key. like with a bussman add-a-fuse. only on the 2003s. no idea y but thats what ya gotta do.

Okay yall, I wish I would'vd found this site like a week ago.
Here's my issue. I have installed my aftermarket radio into my 2003 Impala. It's a Pioneer Deh-P710BT if that helps.

Now my dash lights and tail lights don't work. Also my defogger works when it want's to. Before I pulled out the factory radio I disconnected the negative from the battery to be sure not to blow any fuses during the install. I beleive I've properly identified the dash, tail and defogger wires. Now I just need to know what to connect them to.

I cut the stock harness. Wasn't being impatient, just thought I could install it like I did with my 2000 Malibu.
Another Quesition: If I reinstall the stock harness where can I find a aftermarket harness adapter compatable with my pioneer and Impala.

Thanks for the help :)

Just to let people know, all 200 and up GM cars and 2003-up trucks need a specific harness or interface to keep everything working as if was stock. If you cut the harness you are just causing more of a headache for yourself. Whether it's a standard car with not high amenities to a fully loaded OnStar/Bose setup, you need them.

Anyone see a harness or anything else for 2014 impala? Crutchfield only has the replacement speaker sizes. I'm trying to add an amp and I am having a hard time finding any info. I haven't even managed to get the head unit out yet. Seems like there is too much involved in pulling the dash apart. I feel like I'm missing something.

With the 9th gens, I'd be surprised to find much aftermarket gear for the stereo since it's so "embedded" into the vehicles operation. Not even sure if you could connect an amp to it or not - I'm guessing that it doesn't have any pre-amp outputs, so you'd probably have to use an "adapter" that allows you to use the speaker-level outputs (speaker wires) to add an amp - not entirely sure what drawbacks this introduces though - can someone (@RYD?) comment on adding an amp to a stock head-unit that doesn't have pre-amp outputs?

I just can't stand the direction that cars are going in regards to the radios... WIth some of the newer cars, there is just no way to replace the radio because they are *so* embedded into the vehicles operation (and dash). It's all fine and dandy for now, until a few years down the road when CDs become obsolete and the next "latest and greatest" thing comes out and you are SOL...

For people that really like car audio/video customization, it's a pretty big issue.

I agree with what you're saying jt, it sucksfor people like us. But it's good for the auto makers, because when they become outdated, it will force those who want the latest and greatest to just buy a new car...

He has posted around on here a bunch, and has a handle on what needs to be done (adding a LOC or Line Out Converter), but is having trouble accessing the back of the head unit. Unfortunately, I can't help there...

Cheap LOCs can cause degradation is sound quality, but a good-quality one will be un-noticeable from pre-out RCAs. The biggest drawback is controllability. With the pre-out RCAs, you can adjust the levels of the subwoofer/speakers through the headunit itself, which is not possible with a LOC

Sound System Upgrade! HELP!

Hello,
I have a 2013 Impala LTZ with BOSE/XM/OnStar and would like to make some upgrades to the audio system:

1.Upgrade bass – Alpine SWS-12D4 Dual Voice core (x1) (already Installed)
a.Signal coming from rear deck 6.9 speakers via line converter going to the amp listed below.
b.Using kicker 4awg amplifier kit wiring.
c.Configured at 4 ohms 350 watts
i.Want to configure at 2 ohms 500 but pulls too much power and headlights dim extremely(any suggestions???)

2.Kenwood 5001PS 1000 watt mono amplifier (already installed)
a.Remote wire coming from front passenger floor circuit panel
b.Need help locating a better ground point

3.Pioneer AVH-4000NEX D-Din head unit (factory unit installed)
a.Want to keep XM radio capability
b.Want to keep steering wheel controls and chimes
c.Could care less about the OnStar but Im not sure what all goes into the functionality of having this after new HU.

4.I have a touch sensitive kill switch in line with my remote wire to cut off amp when don’t want base but still want base from 6.9’s

5.Would like to keep the BOSE amplifier powering all the other speakers (Tweaters and door speakers)

I did/will do all the work on my own so would accept all advice I can. I will upload pics of current setup
All that being said what are you guys suggestions as to what I should do/ get (harnesses converters Metro-gmos-lan-0, etc)
PS. Was thinking of adding power to system as well (Stinger batt or capacitor). Lights dim when window goes down or bass is hittin hard

Please please please help!!!

PLEASE PLEASE PLEASE HELP! I am new to all of this and have been searching for specific info on my 2014 Chevy LTZ limited with bose and am finding it extremely difficult. I hate the factory radio in it and am looking to install an in Dash Dvd/cd receiver with back up cam. I have been on Crutchfield and chatted to find out that because my car gets its temperature controls thru the radio it is not suggested to install new receiver. I WANT TO ANYWAY!!! and am wondering has anyone on here accomplished this??? Also would someone be so kind to explain to me the difference between the 2013 LTZ and 2014 because Crutchfield is not showing any parts to fit. Thanks!!

Depending on your needs, you may want to seriously consider a Rosen DS-GM1010-P11. It's a plug-and-play, touchscreen, OEM-look, DVD/Navigation head-unit. You can get them for $325 (refurbished) on the Rosen Outlet site. These head-units are very easy to install, don't require any adapters and retain all factory functions (steering-wheel controls, warning chimes, XM, OnStar, etc).

I have quite a few posts on here about this unit, including a full review. Very powerful unit and it looks like it came in the car from the factory.

EDIT: Here is a link to a thorough review:

Temperature controls through the radio? That's not true at all for 8th gens lol.
You can slap in any aftermarket radio you want, granted you have the correct wiring harness/dash kit.
You may want to look into the "Plug and Play" double din's that JT told you about. If you aren't looking for simple plug and play then the world is yours, you can install just about any headunit you want lol.
