Have a barely used Sundown Audio U12 rated at 1500 watts rms in a probox style ported box with Kicker 1800.1 amp and 0 gauge OFC amp kit with big 3 0 gauge OFC upgrade kit for sell. Works great and box is in good condition. Traded trucks and no longer have a way to use this sub and box. $700 CASH only OBO. This sub alone was $450 and everything together was around $1,400 plus taxes and shipping so please no low ballers. Text me ONLY because I don’t answer calls from people I don’t know.
