for best results.....your are better off running one amp for the speakers......and a separate one for the subs.......
unless you are running an active crossover.......
from the head unit.....use rca leads to the amp......these bypass the internal amp in the head unit......
and give a much cleaner sound by allowing the amp to do all the work......
otherwise.......use the amp for the sub......your head unit may have a separate output for a sub......
and run the speakers off the unit itself.....using the amplified speaker outputs on the back of the head unit......
ok...i just had another look....its only a 2 channel amp.....even better.......use it for the sub.....if you only have one sub......
bridge the amp for more power and run the sub off that......
as for the crossovers......a picture to show what type you have will be handy.......
but they are usually connected in parallel with the tweeter......
as for a wiring diagram.......i need to see whats what with the gear you have......what colour wires there are......how many terminals etc.......
the amp should have rca inputs.....and may also have hi-power inputs.....
it will have the following terminals as well.....
B+ = battery positive....makes sure you have a fused feed for safety.....
B- = battery negative terminal or chassis earth......
R+ = remote switch....this turns the amp on and off either via the head units or via ignition......
then there will be the 2 speaker outlets.....
L+ .......
L- ........
R+ ........
R- ........
if the amp is bridgeable......it will show you which two terminals to use in bridged mode.......


I have just purchased a Pioneer 6950ib, Boss 1200 watt amp, JBL = 2 X 210 watt 2 x crosovers 2 x tweeters and a bazooker sub. (I know the amp is a bit of an over kill but bigger speakers soon). What I am chasing is a wiring diagram for the complete set up. Can some 1 steer me in the right direction?
