I just series wired it like it says here http://audiobahninc.com/tech/wiring/DualLug/1_sub_wiring.pdf and I can barely hear anything.It's 1000 RMS so I don't understand why.Also the wire that runs just from the negative to the positive does it matter if it's a negative or positive wire?
yeah well if he is running it off of a pyle 25x2 at 4ohms and its a dual 4ohm sub then in a series he will be getting 8ohms and about 50 watts. from a good amp that like the Orion Hcca that is underrated that would be fine but if it is a crappy amp he is prob getting more like 20 watts which would be the reason he wouldnt hear anything.
"Also the wire that runs just from the negative to the positive does it matter if it's a negative or positive wire?" this is all im talkin about. i dont know wut is wrong with his sub, like you said, we need some info to try and correct this problem.
