I also have an A8000t, and have noticed that the gain is very, very touchy. But other than that its a great amp. Seems to put out good wattage. i dont notice much of a difference between my bahn and my buddy's 1501d. but thats just my opinion.I run a A8000T at approx. 600 watts with my kicker 12l5 for a few weeks... no problems yet and seems to output quite well. One thing you would probably have to check with these amps, since they are not of the best quality -- (not best, but they have good), is the gains... if you set the gains properly you'll be set.
