First, a question about my current amp. I have an Audiobah A2150HCT. If there is no sub connected to it, it powers up just fine, also if the sub connected to it is playing at a very low level, it still stays on. but as soon as I turn it up to any level that would be OK to listen to, the warning light on the amp turns on, and shuts off for a couple seconds, then the blue light comes back on for a split second before the process repeats itself over and over. I have heard that this kind of thing may be caused by the amp recognizing a messed up voice coil, I was wondering if that could be the case because it is quite likely that the voice coil on the Audiobahn AW1208T could be bad (Dual 2 Ohm VC). On the other hand, I hooked it up to a different sub, and it did the same thing, could it be something with the speaker connections to the amp? Thanks for any insight.
