I am in the process of replacing the audio system in my 2009 2 DR Wrangler which has the stock Infinity package. For theft reasons I am going to keep my existing HU. When I first got the jeep I was in a hurry to get better sound and replaced the front speakers with the Kicker 77kick10 and the tweeters with Infinity 1031t. What I realized when I was done is that the Kickers are coaxial so when they are wired with the existing Infinity amp they are only going to play whatever the existing crossover is set to. Because of the good reviews I have seen I just bought an Alpine PDX5 and I am going to replace the Infinity amp with this. So my question is this, I will obviously run the sub though it's channel, and the rear soundbar speakers off of two more, but is there a way that I can run both the new tweeters and the kicker coaxials off of the remaining two channels. I know ideally I should replace the kickers with 2 nice component speakers and move the kickers to the soundbar but they are such a PITA to change out, I would rather just leave them alone. Thanks,

 

First off, you will need to adapt the speaker level out of the factory amp into the PDX, I would recommend line output converters. Pac makes a piece that gives you RCA outputs out of the factory radio, but I had 2 not work properly so at this time I can't recommend it. And you should be able to run the tweeters and mids off of channels 1 and 2, given they are 4 ohm speakers.

 

Talk to a Crutchfield advisor. They will give you our best options. Personally I would just buy a set of component speakers for the front.

 

so quick update on this. I spoke with a Crutchfield advisor who actually wasn't very helpful, but I found a lot more information by searching around and found out what I needed to know. I bought a PAC harness number AOEM-CHR3 because I am going to remove the factory amp and replace it. I had a couple of people tell me to just use line out convertors but the way the Jeep system is that wouldn't have worked. The only place that I could tie in would be after the factory amp which is already crossed over, if I would tie in before the amp I would have no volume control. I am assuming the 77KICK10's are 2 ohm since they replace the factory system, so I have decided to just install the crossovers that came with the new tweeters with the Kicker's in the front. This means that the tweeters in the coaxial's won't be in use. I bought a second set of 77KICK10's for the soundbar that will play at full range with the PDX5. I am curious to see what these speakers are capable of when they are not being restricted by the amp.
