Default Help me figure this radio out (replacing head unit)

So I bought a new Android Auto head unit and I'm trying to figure out the connections.

I read prior to ordering anything about needing the converter from Crutchfield, so I got that and the new head unit at the same time thinking I would need it.

But looking at all the wires and connectors, I'm realizing I probably don't need the Crux converter as the head unit has harness connectors, much like the ones on the Bose radio in my C4. There are RCA inputs, but they are for L/R out, AV, Backup cam, etc...nothing for the audio system itself.

Help me figure this out. Can I just connect the wires from the car to this head unit's wires and be good to go? Will I need a separate amp unit and go through it to play on the Bose speakers?

I'm also pretty sure that my Bose speakers are possibly shot, but I'd like to plug in this head unit and test things out

before determining if the old Bose radio is bad or if the speakers are bad and need replacing.

Any help will be greatly appreciated!

What YEAR? 84-89, 90-93, 94-96 have different considerations re installation. EDIT: He has an 88. I looked at his profile.

Sorry, forgot to mention I have an 88

Thank you for the help! Let me know if there are any special considerations related to the 88.

Check out this site: https://www.comvette.com/

There's a lot of info that may help you understand the way the old BOSE systems work and are wired.

Bose doesn’t like to be mix and match

Oh, BS. I and others on here that I learned from their experiences while researching my installations have successfully paired aftermarket head units with OEM Bose amplified speakers in C4s. I did a 90 and a 92. Although the connectors and wiring are different in an 88, the OP could do the same thing I did. (If his speakers are ok to use.)

Only reason I haven't attempted to intall the OEM Bose head unit in my '90 is because of the information I've read on here saying hat you cn't use regular old speakers wit hthe OEM head unit.

Is that, to your knowledge, true?

I really would like to have the OEM head unit back in my '90. Really like the design and look of the so-called ''cockpit'' when everything is lit up at night. Silly reason perhaps, but that's primarily why.

Sorry, disregard those last couple of posts here. I thought I was still in the ohter thread where the guy was asking about removing his oil cooler system.

And now they won't let us delete posts for some silly reason.
