Older Alpine CDA-7893 with steering controls??

I've got an old tried and true CDA-7893 V-Drive receiver that I absolutely love. I recently bought a JL CleanSweep from a TW member that should be here tomorrow, but got to thinking that if I can keep my steering controls, I might roll the old Alpine. I sprung for the Ai-Net cable back then that gives me an auxiliary input, so losing the stock aux port on my 09' is no biggie. I love the motorized face that you can change the angles on. Too bad Alpine seemed to stop this!

Anyone have any idea what I need to be looking for in order to see if the PAC SWI-JACK will work?

Also- most of you guys with the two amp set ups are running a 4 channel for the mids and highs, and usually a bridged amp for the sub(s)- Anyone doing well using a 2 channel amp running all door speakers in parallel (2 ohm load)? Other than losing fade, I see no issue...

 

I have a CDA-1894 that I love to death. I've had it in 3 cars. It is not compatible with steering wheel controls.

 

CDA-1894? I can't seem to find that one in order to see if mine is very similar. Yeah, I love the adjustable crossovers and the 4 channel time alignment, I love this old thing. I was stoked to get a brand new detachable face off eBay for $25!!

 

So, I'm an idiot. I mistyped and didn't notice. I have a CDA-7894, not a 1894.

 

I would contact PAC Audio about the SWI-Jack being compatible with your HU or get in contact with Alpine too. You can run a two channel to just the front components or speakers.

 

i believe this is the unit you want

I contacted PAC, we'll see if I get a response.
