Review: Amp built into subwoofer enclosure - Need 5 gauge wiring kit. Take time running wires and have a continuity test light handy for finding a good ground and to troubleshoot if amp for some reason don't have power. Has good sound. Good bass. Overall if your not looking for super loud bass that's not gonna make your ears ring. This is a good subwoofer. Have it paired with Orion 6.75" speakers. I'm happy with the subwoofer amp enclosure
Review: Supplied directions????? - Only resaon not a 5 star is the directions supplied were lacking. I had to call the company twice to get it to work. Sounds great , plenty of Bass. Great product they just need to fix their directions a bit.
