Stereo & Electronics - Aftermarket headunit

Ok i have a 94Z28 and i am trying to connect up a pioneer headunit. And the bose system diagrams show it to be very difficult. Can anyone give me some advice on how to wire this up?

i had a buddy that had that bose system and decided not to even mess with any aftermarket stuff cuz that was such a bitch to remove, good luck

Bypass Bose altogether. :judge:

You basically have two choices - the cheap way (relatively) or the expensive way. The Bose system uses a special head unit connected to speakers that each have individual amplifiers so just plugging in an aftermarket head unit won't work.

The inexpensive way is to buy an adapter that is designed for connecting a new head unit into a Bose system. One model is the ROEM-GM21 from Pacific Accessories Corp (PAC), makers of the SWI-X and various other accessories that are well respected around here.

The expensive way is to gut the system and install all aftermarket equipment - head unit, amp (optional), speakers, and sub (optional). This will give you a custom system with components of your choice but it will cost a lot more.

you can just use a regular gm harness and hook ur headunit up to the bose system, just make sure to hook up the remote turn on wire from your headunit to the power antenna wire in the harness and it will be fine, if the volume is supser sensitive just splice in rca connectors and tap the rca lines on the headunit and it will work fine

We're talking about 3rd generation and early 4th generation Bose systems. They are completely different from what is sold as a Bose system in later model vehicles like TrailBlazers. The head units produced high-voltage, low-level (pre-amp) output into individually amplified, high-impedance speakers with 3-wire, common ground wiring. They also used compression and active equalization in their output - so even if you could get a head unit with the correct output levels, it would sound like crap. There are a few head units on the market that are designed as Bose replacements but they are scarce, expensive, and not particularly good. The adapters like the one from PAC act somewhat like a LOC but also take care of the equalization and compression so that the original Bose amps don't end up sounding like an old transistor radio.
