Can somebody please help with this headache of an install??

[sepenator]

Alright, well I have a 2000 Bonneville SSEi, I have OnStar, but I don't know if I have the bose system, i don't think I do though, but anyhow, I'm trying to install a head unit, and I get power to the unit, but no sound, I hooked all the wires to the proper harness I got from my local sound shop. Please help... I'm getting frustrated.

Tell us what kind of aftermarket head unit you're trying to install.

2K SSEi should have the Bose system.

Also, what dash install kit would fit for this setup? please and thank you!

The harness interface you bought says "Non On-Star" and you said you have On-Star. Maybe you just have the wrong harness interface?

[myfirstbonnie]

Also says non-amplified and you are.

Maybe more like this one:

Also says Non-Amplified, and your system is amplified.

Do I need the OnStar and all that jazz? if I didn't want the chimes and the amp, can i just get the cheap harness?

[Bugsi]

SonicElectronix has pretty good tech support. Email them and ask them if the harness adapter module you got is compatible with your car and its features.

My understanding from buying other harness adapters like this is that there's a model that works with your car, and the other models don't. It's not a thing where you pick and choose which features you'd like to keep from which ones you don't care about losing, and then buy an adapter that doesn't have the features you don't care about. The radios with and without those features have different pinouts on the connectors, so if you buy the wrong adapter, it generally won't work with your car.

pooey, this is becoming much more hassle than it's worth now =\

[Bugsi]

What, just because you didn't buy the right harness adapter interface?

For future reference, you could take advantage of the vast collective body of knowledge in this club and ask what adapter to get, before buying the wrong one. When it comes to radio replacement in a Bonneville, someone probably did it before you, and knows what pitfalls to watch out for.

[sepenator]

well it's not that I bought the wrong one, just that my local shop didn't give me the right one, and I just found this site last night =P and i don't really have the 100 and somethin bucks for a new harness =\

[harofreak00]

Bring it back to your shop and demand a refund.

[sepenator]

I've already cut and stripped the wires, I don't think they'll take it back

If they sold it to you as working with your car, I think they kind of have to take it back. If the mistake was on them, and through no fault of your own you got the wrong part, then I think they have to take it back.

[harofreak00]

As long as you buy the correct one from them, I don't think they will turn you down.

[sepenator]

alright, i'll give it a try

thanks guys

Oh and hey, "Welcome." -now you know where to ask first. For audio stuff you can research what other people have installed and ask opinions on stuff you plan on installing, and you're sure to get some good advice.

[sepenator]

haha thanks, wish i found this a week ago though, woulda saved a lot of hassle, btw, with the new harness, am i gonna have tp get RCA cables?

EDIT: Geeze, the wire harness for the bonneville is almost IMPOSSIBLE to find, I've searched crutchfield and can't find the one I need.

[Bugsi]

Typically you need to get an adapter from Pacific Accessory Corporation, one of their OEM adapters.

[Edit: Wait, someone already posted a link to the Axxess GMOS-04. Isn't that what you need?]

Crutchfield or SonicElectronix typically carries them.
