ive been having troubles with my sub...ive tried two different amps but still the same thing happens. i cannot wire my sub at 2ohm..only 4. if i do wire it at two my sub goes hay-wire. ive got it wired at 4ohms right now, when i touch the medal on my amp the sub goes in and out. Im guessing its to do with wiring but ive checked everything i can think of. if anyone has any suggestions it would be a help.thanks
