linking two amps.

linking two amps.

Okay, Let's say I've finished dealing with the front two speakers.. as
it is quite loud I decided not to mount rears speakers.. at least for
some time now.

I've decided to put a subwoofer / bass speaker though, so here is my
idea. My first amplifier being a 2 channel Audiobahn 40 amp amp with
RCA input (which is pretty obvious) but also a RCA output pair. So as
far as I can tell there shouldn't be any issue with connecting a
second amp to the first one? But would I need to change the AGU fuse
on the battery? If it's a 40 amp at the moment - and the additional
amp would be a 30 Amp one, shouldn't I change the 'main' fuse to 70
Amp?

Thanks in advance to all your responses,
Morris

Yes but....You probably don't need to because both amps most likely wont
pull that much power at once. If they BOTH arent running subs and are
crossed over then you will probably be ok. If it does need that much power
then I would be looking at the size of the wire going to both amps or adding
another power cable to the new amp. Depending greatly on length you would
need something like 4 gauge to get 70 amps to the back of a car without
voltage drop. I like to run welding cable if its a run front to back.
Bottom line: Try it first and see if it blows :) OR run a second power
cable unless u have a REALLY big power cable allready.
Oh, if you do run a single cable make sure your amps are protected
seperately by the correct fuse also. (the one usually on the amp itself) The
fuse by the battery is to protect your cable from burning your car to the
ground if it shorts.
