Finally upgrading headset

Picked up the Alpine 9887 for ~$290 with the kit and the antena adapter. I have the steering wheel controls and honestly opted out of keeping them because the stereo comes with a remote and the 60 bucks it cost could go towards something else.

I have the infinity system and just wanted to make sure that we all pretty much still agree that the only way around this is all new wire to the 7 speakers?

Anything I should be careful of when attempting this install? On a 10 scale I classify myself a modest 8 when it comes to installations, so if you want to be technical, I understand well.

Thanks for the help, guys!

A HU install should be pretty easy to do. I would think there has to be some kind of adapter to that would allow you to plug directly into the factory amp.

Apparently, there isn't. Crutchfield says all new wire to the speakers.

How does everyone wire 7 speakers to only 4 leads?

You may need crossovers to separate the high/low freqs between the door and dash speakers.

You mean passive cross overs to block the bass? Or do you mean an active (electronic) x-over and then amplify them. What I'm trying to do is use the stereo outs to do the doors and dash speakers, then have my sub be the only thing amplified. This head unit has a built in cross over (high range) for the doors and I can program how much bass the doors get if thats the worry. My question was more of does the impedance go up or down if I'm wiring more than one speaker to the stereo out.

If it sounds like crap, I have a set of boston acoustics laying around.

It all depends on if you are wiring series or parrallel. I dont see any issue wiring more than one speaker per lead, I have done that and had no problems, just dont expect the cleanest or loudest sound out of speakers wired to the deck.

Gotta be better than stock! lol

I'll post some pics and junk of the progress and throw in my 2 cents later.

Thanks all.

Well...took a little longer than it needed to thanks to the 5 beer breaks I take an hour

Ran all new wire to the 6 speakers (left the center high on the dash unplugged).

I have to admit, I was a little dissapointed at first regarding the subwoofer power level that comes out of this deck. It's not bad, but it was louder (not better) with the LOC. This was probably due to me not knowing how to set up the head set (waaaaay too many options)

After messing with it and getting everything in, it sounds a lot clearer, a lot louder and I figured out the sub control a little better. The only thing I notice is I need to install some form of bass blocker on the dash high's else I'll blow them up soon.

Pic later if I remember.
