I see alot of amp bypass question's
But no one really has giving any real answers (Till Now)
"this post is for anyone that wants to upgrade their cd players"
there is no reason to fully bypass your factory amp.
instead just use it, it wont hurt nothing plus your better off having your speakers amped anyways.
when your installing your aftermarket cd player.
there is 3 plugs and a ground(black clip thingy).
black and gray long plugs witch is you batt. and speakers.
then there is a smaller whiteish plug wit a single wire running from it,
this is the remote for your amp just simply cut splice an connect it to the remote wire on your cd player(where you would connect your subs amp remote) and your golden!!!!
for aftermarket and factory amps used togather
use male and female crimps
crimp one to the remote wire from your aftermarket amp
and crimp factory amp remote to the cd players remote(2wires one crimp)
so its simply a 3way
happy sounds folks
have a wonderful day
