Looks confusing to install, but is actually straight forward
on October 23, 2012
I installed two of these this past weekend. Both in new Jeep Wranglers. When I pulled it out of the packaging I was confused. I'll give you some pointers on installing this.
First of all you will need 4xRCA outs coming from your head unit. Most (if not all) decent aftermarket stereos include these. There may be two more for the subwoofer.
There are two sides to the unit: the harness that plugs into the left is for your speakers, remote turn on lead, and power. All you have to do here is match up each wire with what comes off the wiring harness you bought for your stereo. Use solder to connect wires.
The harness that plugs into the right side is where the RCAs coming off the head unit plug in to. The RCA harnesses that come with the amplifier are labeled F/R, just make sure you match them up with the RCAs you have running off your head unit to the Alpine harnesses. When you have them connected you should test L/R and F/R on the head unit to make sure they are matched up properly.
You have to buy 2 sets of RCA cables as the amp does not come with them. After you buy your new RCA cables, run them from the back of your head unit, into the RCA adapter harness, then plug that into the right side of the Alpine amp.
8 month update: Still works great and runs cool. It is still in my glove box without issue.
