So Ive had this sub for years and years and years (10 years?). Anywho it has always worked perfectly, what a beast in a small package. I hooked it up to my Sundown SA-8 V2 Dual 4ohm wired in series. As soon as I hook it up it starts playing extremely low, barely playing. I turn up the gain then it goes down to an inaudible level, even with gain turned all the way up. The amp IS working however barely even noticeable amounts.
I also tried hooking it up straight to ipod via RCA jacks with the same result. Playing the song i know it should be its just inaudible and only know its playing if I press my hand on sub and BARELY feel it moving. Amplifier problem huh?
