Bypass Infinity Amp

So I've been lookin around on the internet trying to figure out exactly how to bypass the infinity amp in my truck.

I plan on getting a double din.

Do I just need to get a 2 channel amp and run the wires directly to the door speakers and to my sub? I only have a 1 channel amp now and it's powering my sub.

Has anyone bypassed the infinity amp before? Could you tell me how to do it?

Are you trying to bypass the infinitiy and use the stock speakers or are you replacing everything?

I have Rockford Fosgate 6x9s in the doors, but I think my factory amp is out because there is static with the bass turned up even to -4 lol

So I want to get a new head unit and I guess I'll have to wire up all 7 speakers to the new amp or just the door speakers and back speakers and forget the dash ones

you can run new wires from the new deck directly to the door speakers, or if you want to amp the door speakers you would run new wires from the amp to the door speakers.

ok awesome thats what i thought but i didnt know if that was right or not lol so i need like a 4-5 channel amp?

A 4 channel amp is for running one channel to each of your door speakers. A five channel amp includes a channel for your subwoofer(s). If you already have an amp for you sub(s) I would say just a 4 channel would do it. If you have the speakers in your dash and want to amp those as well...maybe you could run those and the front doors off of a channel? I'm not really sure there.

I see that you have a single cab truck, if you want to save money, I would honestly just get a 2 channel amp and amp the front speakers and run wires from your new head unit for the rear channels to the stock speakers and power the stock rears with the head unit. Reason being is in car audio front stage is 99% of what you hear while the rest is just rear fill. For example, I have a 2002 Trans Am with Boston Acoustic Pro speakers in the front amped by a JL300/2 amp and it gets PLENTY loud to where no one even knows I dont have ANY rear speakers and I can't tell a bit of difference. Point is if you do the front stage properly, a rear stage isn't even necessary, but that is all listener preference. You can get a 2 channel amp on the real cheap obviously and a cheap wiring kit and sounds like you are good to go once you decide on a head unit. Hope that helped

Alright I think I'm understanding it all, I appreciate the help guys and I will get back to yall if any problems come up

If I go this route and run all of your interior speakers either off of an aftermarket amp or directly from the aftermarket head unti do I still need to purchase the $100 headunit wiring harness or can i just get a harness that will give the head unit constant power, switchable power, and ground? Will this mess anything up in the truck in general or will this be fine? If so, what harness would I need to get?

i could be wrong but I think the harness for the power to hook up to the canbus is the expensive harness.

And the canbus is the part that is integral so nothing goes wrong with the truck in general in doing this?
