[QUOTE="TheBigPilferer, post: 8863567, member: 690294"] The first thing you should do is double-check all of your wiring connections. Usually when people come to me with this issue it's a loose ground or a bad RCA cable. If everything is snug, grab a multimeter and set it to Voltage AC and probe the RCAs going to the amp and the speaker leads. Depending on your head unit/DSP, you should get anywhere from 2-6v at full volume on the RCA. Since you said you're capable of 155 db, it's clear that you have some decent power. Voltage = ✓(watts x impedance). With this is mind, probe the speaker leads and see what voltage you're getting. 3000 watts is about 54 volts @ 1 ohm, for reference. I'm willing to bet this will solve your dilemma. [/QUOTE]
