Apologies if this has been covered before, I've done some searching on the forum but couldn't find a thread that really covered what I was looking for (probably because it's a really stupid, basic question, but this is all new to me).
So, I picked up my new 2013 JKU Sahara three weeks ago. I knew I was going to replace the HU so I got the 130, but it does have the Premium package with the amp and the Alpine sub. This weekend I replaced the HU with a JVC KW-AV60 (chosen because it is a double DIN with removable faceplate, which I felt was a good idea with a soft top) and the PAC RP4-CH11 harness. The whole replacement process was easy and fun and it looks great, but here's my problem.
The PAC documentation said to connect the rear speaker outputs from the HU to the front speaker inputs on the harness and leave the others unconnected due to the fact that the factory amp only supports two channels. As a result, fading would not be possible. I did as they said, and they were right - while sound comes out, fading is not possible. I'm also presuming, although I haven't checked, that the sub is producing little or no output.
This isn't acceptable to me, so I'm assuming that I have to replace the amp with something capable of accepting and processing the output from the HU to give me control of all the speakers. However, I know nothing about ICE. Do I need a four channel amp, or five? Are there some that will work better with the stock speakers, or should I be canning all of them as well? Do I have space constraints for a new amp going into the location of the current amp? Is this something that someone with no knowledge of ICE or car electrics, but is reasonably handy, should even be attempting?
Any advice gratefully appreciated.
