[QUOTE="fixinit, post: 8536430, member: 670893"] Thanks for the replies. After soaking this in a little bit, I think I know where you're coming from. I ended on turning up the volume on my deck (not amp gain as suggested) until my rear 6x9s stopped getting louder, then backed off a few dials (30 was the magic number). Went back to the [0dB] test tone and threw the gain to read low 40 something Vac which was about 50% gain. Then added another 10-15% gain. Popped in a 'Bass Mix' CD and drove around town for 15 minutes at volume 18-20, pulled into a park then pushed a heavy hitting song 'yelawolf - trunk muzik' to 25 on the dial. Physically inspected the amp and it was bone cool. The sub was cool and didn't look or sound to be clipping. No dimming when I had my low beams and hazard lights on. Electrical system is stock '93 Camry 2.2 btw. So far so good. As for the statement about my amp only pushing "400 actual watts after impedance rise" - I'm thinking that number is on the low-side according to my [I]bleeding[/I] earbuds at the general tonal range of my preferred music after tests. I'm planning on getting accurate benchmark tests on this amp if I can find a shop who'd do that for a reasonable flat fee, then I'll share - without impedance rise - what she's capable of. Mind you, for trunk space and more so weight, I went with an enclosure that's nearly For google search result giggles since there's none out there.
