what do i need when replacing ENTIRE jbl system

Hey guys. I have an 09 double cab. It has the stock jbl system and im looking to replace the entire thing with a new HU, amp, and sub. I wont be using the stock amp/sub enclosure. I have my own custom one. My question is. What all do i need to make it work. This is what I'm looking at. Pioneer avh-p4300dvd with the steering wheel control adapter powering all the door speakers, and my amp to power the sub. I know the jbl amp powers the rear door speakers, but will I need the bypass if Im replacing everything? Or can I use the normal wiring harness and wire the rear door speakers to the new HU and the amp and sub to the HU like normal as well? I'm trying to figure out what parts to order before i actually do so. Any help is appreciated. Thanks.

 

check out crutchfield

you need...

1.) Wiring Harness
2.) Dash Kit
3.) Speakers & HU (obviously)
4.) RCAs (for the amp)
5.) the correct AWG for the amp power (usually 4-8AWG IIRC, depending on size)
6.) Depending on door speakers, you may need the mounting plates (via *********)
7.) Sound-dapening for the doors (optional)
8.) An assortment of crimp-connectors (or solder and soldering iron) and heat shrink

I think thats everything...

 

Just hook up everything but the speaker wires to the headunit. Then run all new speaker wires to your door speakers and run those back to the amp for power. This will completely bypass the JBL amp.

 

Thanks whippersnapper.. that was fast BTW. Lol. So would you recommend keeping the jbl amp to power the doors or just use the headunit? Also, would I need the normal wiring harness AND this one? Or just this one you showed me? I don't have the product names since im at work..

 

Got ya. Id prefer to ditch the jbl amp and just use my aftermarket one. Less clutter that way. The HU should be able to power the door speakers pretty good. Enough for me atleast. So if I go that route then I will need the normal wiring harness.. and then run new speaker wire OR use that harness you showed along with the normal harness correct?

 

True. I'm sure a real pain tho. I guess I can just order the normal wiring harness and go from there. That harness you linked to requires me to keep the jbl amp though correct? Thats what I'm getting out of it.

 

I see. So instead of the speaker wires plugging into the amp.. they plug into this harness which is plugged into the headunit. Right? If so thats exactly what im looking for.

 

Cool. Ill give eBay a look. Hopefully between the normal harness needed and the Metra one it will work. If im understanding it correctly it should with no problem. Thanks again. I appreciate it!
