I was going to work and everything was working fine for about 5 miniutes, then my subs went real quiet. by the time I was there they stopped working totally. I thought my amp was blown, but on my way home the same thing happened again. I checked all my wiring and it all looks fine. I'm thinkin my HU may have something to do with it cause it flips off then back on right before the subs go quiet.does any one know what might cause this??? ps.I've had the subs and amp for about 2 months and the HU about 1 month and it all worked fine till now.
