This weekend friends and I will be doing the audio overhaul on my 12' Altitude with the Alpine System. Parts are listed below:

Focal IS165 components
Focal IC 165 coaxials for rear doors
Alpine SPR10tw for rear surrounds
Alpine PDX v9 amp
Audiocontrol LC7i
Mega Mat

At a later date a stealth box will be added.
I found the wireing diagrams from the stock amp here for tapping to the converter.
I will be posting in here pictures, install tips and review of the sound when done. Should have this done in a day and a half.

Nice choices! You should have an awesome sound system once everything is installed. I noticed that you will be using an LC7i so are you keeping the factory radio?

That is correct. Factory 430 will be kept to be able to keep stock volume control.
What exactly do you mean by "stock volume control" ?

Thanks for the advice about the Matt.

As far as the stealthbox goes, I am getting married in June so I hinted that as my wedding gift. lol. So for the time being the stock sub is staying, and all we are going to do is run the speaker wire off the new amp to where the stealthbox goes so when I do get it all we need to do is take apart that corner and replace the sub.

Should be a very nice system once everything is said and done. I'm getting the same amp and sub as you, just started ordering all the install parts. I'm curious as to where you plan to mount the amp, I was thinking under the drivers seat but haven't finalized on that location yet.

Looking forward to seeing your build.

Moose is right, there isn't much space to install deadening mat. I've done this myself. The largest place would be under the spare/cargo area and the roof, but i doubt your going to do that. Not many people are foolish enough to take on the task of removing the headliner. It was one of those things i started and half way through thought, what the hell am i doing! But now I'm glad it's done.

Anyway, I'm very interested in how you retrofit those tweeters into the rear.

I just got done installing:

165KRX2 Components
3Sixty.3
Center dash speaker
Stealthbox
Dynamat
Speaker wires to the door
JL XD400/4 and JL XD500/3 amps


Let me know if you have any questions and I will try to help if possible. Mine took me about 3 days to install, but it was a little each day.

Good point, I still have the LO Converter and amp under the rear seats, and they do NOT fold flat. The rear seats shift forward and down so take note to put thegear far enough forward, or perhaps use alt locations as shown above or under the front seats.

Progress from day one. Interior out, and all speaker have new wire runs and RCA cables run. Should be finished tonight but for now here are some shots....


Tearing the interior out was kind of easy. Tool maybe 2 hours total. Running the new speaker wire took some finagling but its all in.

Letting the amp, these Focal's crossover's are built in therefore no crossovers are needed. Tuning will be done by the amp.

All speakers are in doors, door's are reassembled. Now taping the stock amp output for high's, mid's and lows. Once thats' done just mounting the LC7i and AMP and connecting it all then the big test. Adding the power and seeing how it sounds.
