Amplifying component speakers

[nodrog321 10+ year member]

hey guys, so right now, i have a set of polk db6501 with external crossovers for the front and a set of JL690-cxi for the rear deck. these are all being powered by my pioneer f700bt.

now i am looking to get a 4 channel to amp all 4 speakers. i know many people say to just leave the rear speakers but if i bridge the two front speakers, the amp i am looking to get will be over the RMS rating.

my question is, i know i can probably get the rear signals through the wires that go into the rear speakers. but how about the front with the crossovers? how do i wire the front speakers to the amp? Right now, the crossovers are sitting INSIDE my door panel. I have no idea how to route any wires INTO the cabin. do i just get the signal from the wire harness that connects my pioneer HU?

i have a 2007 honda accord by the way.

thanks

Where are you putting your amplifier? I would try to use the factory wiring as much as possible. If you are putting the amplifier under your seat, then just send the wiring from the amplifier to behind your dash, and connect it to the car speaker wiring instead of your headunit. If you are sticking the amplifier in the trunk, then you use the current wiring to your advantage as well. Take the wiring at the rear speakers, and move them to your amplifier in the trunk. Use the left rear speaker wiring for the front right amp output, and the right rear speaker wiring for the front right speaker output. You now have immediate wiring to the front of the car. Now, go behind your headunit, and connect the rear right speaker wiring to the front right speaker wiring, and the rear left speaker wiring to the front right speaker wiring. Without running ANY additional wires, you've just wired up your front speakers! For your back speakers, two pieces of 3-foot-long wires will reach from the amp to the rear speakers.

is that really how its done? that seems like.. a weird job lol. i was thinking i can just splice the front left and right speakers in the wire harness that goes into my pioneer HU and route them to the trunk to the amp.

since my HVAC controls are built into my original HU, my pioneer HU is connected to the original HU via a Y harness cable. i was thikning of just splicing the signal from that harness. so it would go... amp->pioneer HU -> OEM HU-> crossover -> speakers?

Or u can do it right and just re run new speaker wires.... Not hard at all may take a few moments but well worth your time...

im not sure how to get the wires thru the door to the cabin, if i did i would have relocated the crossovers. i think it has some kind of connector for my car on the drivers side door.

Its called a boot. And its easy to get threw. I use a close hanger with dull end wrap tape around it at very end with wire attacted to tape and feed in threw may take a few tries but It will wrkk..

sometimes you have to cut a slit in the boot.

Tru enough or removes boot from both sides of door and feed threw then reconect boot on both ends.. Its a pita but its worth it.

wait did I read that he's got TWO hu's running? if so you know theres a dash kit for that!

yea i think the passenger side door i can run the wires thru the boot. but the drivers side theres a some kind of connector in the boot and id have to drill a hole through the connector.

here are pictures of it from another member in my forums:

i was hoping to find a way so i dont have to drill any thing to get it through.

also for my car, my hvac controls are connected to my OEM HU. so i cant take it out without losing the HVAC. i know there are kits out there that has the controls but that one is only for a single din. I have a double din navi under my OEM HU. the OEM HU is basically only used as a clock now. Heres a picture:
