i have 2 12" r's in 1.5 sealed enclosure each with a 2400 rms xtrpro orion. when turned up i get a squeel, dj scratch sound hard to explain but only does it at lower notes when turned up then at a certain point it does it...dosent really bottom out just that noise. and the voltage drops to 11.9 -12.5 under a load. could that cause the amp to send a bad signal under strain since the volts aint up?
