Any (most at least) 4 channel amp have 2 sets of controls (gain, x-over...) - "front" and "rear"
When bridged into 2 channels some amp's "front" (or "rear") becomes the only one to use for both speakers but some amps still keep both sets of controls so in reality u get "left" and "right"
I just installed PA200.4 and apparantly when bridged it turns into "left" and "right" which is absolutly fine since they are powering my comps in the front door.
BUUUUT - is PA500.4 the same way? If so then how does "bass remote control" come into play??? Will it only work for the left (rear only if 4 channels are used) or will it work for both??
I'm using bridged pa500.4 for rear door 8''midbass woofers so having a functional bass remote control def comes in handy.
