[QUOTE="paintballer, post: 2351422, member: 560259"] First of all, my setup to the best of my ability is this : [B]-One Alpine MRP-M650 Mono channel Amplifier powering the subs. its 400w x1 at 4ohms, and 600 watts RMS x1 at 2ohms.[/B] [B]- MTX Dual 12" 1350W Subwoofers/Enclosure. It said the the box handled 450 watts RMS. Audio express told me that the whole box handled 450 Watts RMS for that there was only one connection terminal spot for the wiring. (TCE4512X2D) [/B] [B]-and the rest doesn really pertain to the problem/question. but [/B] [B] [/B] [B]-Alpine CDA-9856 , 4 guage 1000 Watts wiring amplifier kit, a distributor block, 2 TMA coaxile speakers, and 2 TMA 1 way speakers with seperate tweeters, and a 4 channel TMA amp that is like 60 Watts RMS x4 or something like that, and 1 huge 300 dollar plus capacitor block.[/B] THe two problems are these. 1.) The other day i was messing around with the sub volume and cranking it up loud just to hear loud bass. I cranked up the ub volume, and it was working fine and hitting good. all of a sudden, the subs got really quiet, you almost couldnt even hear them, so i was liek shit, i probably damaged them some how. and the speakers worked fine still. I turned off my cd player, and turned it back on and it was fine. the subs sounded good again.
