07 Nitro R/T Help

I am putting in the audio from my truck but I am going to keep the factory head unit/nav.

Where can I find a clean signal and will I run into problems with the factory amp. It has the infinity system with sub + mids and tweets in all 4 doors. from what I read the factory amp Is in the back and runs all speakers.

I am only installing my mono amp and sub.

JL Clean Sweep? You can find the Wire that goes to the factory sub and put a LOC onto that so it only gets the signal going to the sub. Unless by sub you meant dedicated midbass in door. May want to just pull full signal and let the amp do the filtering.

Or find input into factory amp and tap in there before amp with LOC?

Someone correct me if Im wrong. Probably better advice to be had on here than mine. Somewhere to start though, good luck!

I mean factory 8 inch in trunk area. Thats what I was thinking is pull directly from there but would I want the amplified signal orntry and find something before the amp?

There's a good chance in that vehicle you aren't going to be able to use the pre-amp signal. It's normally a fixed-level, with the volume control actually happening in the amplifier. The crossovers and factory EQ is all handled within that amplifier as well. You've got two options here: One, tag onto the factory sub Wire with a normal LOC. This is going to give you useful signal but I have no idea where the OEM crossover point is or what EQ'ing is done in amp. It may also be volume dependent, which means the EQ or even the overall output level varies depending where you are on the volume scale. This way will work, but it's not the best way. The best way would be to use a Pac C2A-CHY23 module. This part gives you a clean, flat 20-20K RCA output right at the radio.

Thank you

Ooh I just thought of something....that pac part is a newer version of an older part. I know on the old version it disabled all audio to the OEM amp, and you want to use that to power everything else. I'm not sure about this newer version. I've only used when replacing the entire system. If you decide to go the module route you might want to call them to verify that it will still pass signal to your OEM amp
