ok lets use the JL Audio slash series amps as an example. ok usually on the back of a mono amp theres supposed to be 1 set of outputs (+ -) now on the back of any of the JL mono amps they have ( + + - -) wats the purpose of this. And JL isnt the only amp ive seen this on ive seen it on a MTX amp
Hmm, I am pretty sure that all mono blocks still have 2 x + and 2 x -. It looks like a 2ch but it's still mono. That is what I have always seen anyway.
