Help with Infiniti Amp..Need the masters.

K, so I am getting ready to do by build and remove all the Infiniti crap, but am keeping my 730. (I actually like it.).

I have another amp that I will be using. It is the Alpine PDX-5. I will be using the AudioControl LC6i as my line out converter and to level out the signals sent by the head unit.

So here is what I need to know. Looking at the wiring diagram I have found on the net, it looks like the different channels (left/right, front/back and sub) are not divided up until after they go into the Infiniti amp. Is this right? If so, then I will have to leave the Infiniti amp in the Jeep right to maintain the channels. Or am I missing something?

Thanks guys.

Gotta bump this thread.

I just received my 2012 JKUR last week and am looking to replace the factory amp and speakers.

Anyone successfully done this while keeping the factory nav/radio?


THANKS!

Yup. Lots of threads on it. I've done a couple of flavors

3 options

1 connect in post factory amp with a combiner. Jbl ms8 or the like. Use that directly to amp the speakers or drive the amps. That was my first setup

2 connect the rear speaker outputs of the head unit ( which are the to signals that go to infinity) to an amp with remote volume control and channel splitter. Again ms8 or similar

3 ditch it buy aftermarket and hook that to the amp

1 actually did quite a nice job for me

2 was a pain because you have to use the ms8 for volume

3 is where I'm at now and it rocks!

Give me a minute and I will find you a link that has the wiring diagrams for the input and output of the Infinity sound-processor/amp

I am starting/doing mine next week, I am keeping the Factory nav, I love how user friendly it is and all the controls it has so I sold my Pioneer x930bt head unit.

My system will be

Factory 430
factory infinity sound processor
LC6i
Arc Audio XDi805 5 channel amp
Focal components front and sound bar
CDT 8" sub

Finished install last week and it sounds like crap. I am about ready to yank everything back out and go back to stock.

The speakers sound very tinny almost like an am radio. I have the crossovers set to -6db and this helped some but very fatiguing on the ears.

I don't know what the heck to do - took it to local stereo shop and installer made a few adjustments on the amp and said "I think it sounds pretty good for a jeep. What does that mean?

I am not changing the H/U, I like the functionality and I just sold my avicx930bt because I was sure this setup would sound good.

Have you double and triple checked all your speaker's polarities? When you're interfacing with factory wiring, it's easy to get speaker or two wired in reverse polarity, putting the system out of phase. I have heard a few systems that had even one speaker wired out of phase with the rest of the speakers, and the whole system sounded off.

What are your HPF and or LPF frequency settings? The 4 channel settings should be around 80-100 htz High Pass Filter, while the sub should be on about the same frequency Low Pass Filter. If there is a gap here, or if these are set wrong, you can get some weird sounding situations...

Turn off all equalizers on the deck as well. You are interfacing after the factory sound processor, and then further processing it; you want to make sure that any changes in EQ or sound processing are done with your new aftermarket stuff. Keep the source signal as clean and true as you can.

Just a few suggestions without actually listening to your specific system.

Hello Eboven,

I did some more adjusting yesterday and the music from my ipod sounds pretty fricking awesome now BUT the music from Sirius or FM still sounds way too bright.

I am going to keep playing with it for now.

Thanks for the input,
