Okay, this is what I have to work with....
US Acoustics 4050 (50x4) amp...yes, I know it is discontinued 
Sherwood XN-1000T crossover
subwoofer (JL) in a box
really old stuff....so any old school cats out there willing to give this Frankenstein project some much needed advice? How do I run power to the front speakers, the rear speakers and the subwoofer with this equipment? Head unit is an Alpine CDA-9827. |

if you are planning on running your entire system off that amp I guess you would run your mids and highs off of two channels and run your sub off of two channels bridged! thats what I would think but ask Glass Wolf he will be able to help you out more. In my opinion I would use that amp for your mids and highs and get a seperate amp for your sub/subs!

well first, I need to know the impedance of that JL sub box.
is it 4 ohms?
if so, you can do one of the following:
run the sub on the rear two amp channels, bridged, and run the front speakers from channels 1 and 2 of the amp, and rear speakers off the head unit's rear powered channels
or,
sub on the amp rear bridged channels
and wire front and rear speakers to the front 2 amp channels in parallel.
this will give more power to the rears but no ability to fade front to rear
