Howto: p11 amp bypass, 56k=death

[iamthejae]

you are correct, if you get a new stereo, or head unit you bypass the amp. you dont connect the amp plug back into the factory bose amp, esentially you could cut off the factory amp connector, this how-to just 'jumps' past the amp taking it out of the loop.
once you bypass the amp, you could take the factory amp out of the car, its a waste of space imo.

sound originates at your stereo, which sends it to the factory amp, amp receives audio signal, increases the power and sends it out to the speakers.

when you get an aftermarket amplifier, you do the same thing, only you use the rca outputs on your head unit to send the audio signal to the aftermarket amp, and then the aftermarket amp increases the audio signal and sends it to your speakers, only in wire form, not rca's (cuz your speakers dont have rcas on them silly)

hope that helps

yes could not have been more clear. so if you change your amp or headunit you still have to bypass your amp anyways correct?

but wait! what if you just want a new amp?

you dont have to bypass the factory amp, there are wire harnesses that are made to integrate the amp. that means use the factory amp with your aftermarket head unit. there are lots of those wire harnesses made but any standard nissan harness will suffice, just hook up the blue/white amp turn-on and your good to go.

aftermarket or factory amp?

aftermarket: head unit sources the sound, rcas from head unit go to aftermarket amp inputs, amplifier does its job, sends sound via copper wire to speakers (the easiest way to find all 4 speaker wires together is at the factory amp, then connect them to the speaker side of the wires.

factory amp: just plug in the factory connector

Guys just want to point out that the factory headunit in a p11 has pre amplification coming out of it... So it gets amped twice...

Running my Pioneer HU off the stock system and everything is working fine!

So there is no point in bypassing the stock amp unless you are adding a second amp to use in place of the stock one... (and wanting to use stock wiring)

i bypassed mine about a week ago. shoulda done it a long time ago.

the buzz that was comming from my rear speakers is gone. and it made it easier to get my sub amp set at a level that complements the speakers. (before it was either too loud, or too soft)
