[QUOTE="hispls, post: 8640342, member: 614752"] I have not clamped it, but I have learned of another brand that uses the same board (sold mostly in Europe). The barevids guy on youtube that does amp repair has about a 6.5 hour video of him working on one. AFAIK he is waiting on MOSFETs to arrive so he can finish it. I expect much of the time it took him is he repairs the driver card if it's gone out. Anyway, he usually clamps things before he finishes.. at the very least the rail voltage should be telling. If you're having trouble with battery now a bigger amp won't help you. Assuming you have pretty much anything besides a trunk you should be able to get some solid numbers too. Most of those TC subs work fairly well in small-ish boxes IIRC. You absolute madman. Keep an eye on the classifieds. Meters come up used here and there. Also if one of those companies comes out with a new entry level price pressure sensor it should be very reasonably priced. Should hold decent resale value as well for what its worth. You can usually pick up .5 in gains with little stuff if you have some time to test. Some people can 'find' much more. What vehicle? Single 15 should be running out of excursion unless you're tuned a bit higher and aggressively using subsonic filter. Low notes require a LOT of displacement and as you tune low to control the cone low you'll lose cone control away from (above) tuning. Are you wired to 2 ohms as well? [/QUOTE]
