When you bridge amp they some time double in power output into a certain load. If the actual load of your speakers are lower than the required bridged load the out put of the amp will proportionally try to increase again. You have to match your loads to the specs of your amp. Use your manual to see what is required, then use ohms law, for adding resistors in series/parallel to make your speaker load match. For more info please reply.

if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

first of all you should check the minimal impedance your amp handles , if is class d it should handle between 1-2 ohms total impedance in a mono conection , meaning whatever quantity of subs you have hooked to your amplifier,their total impedance should the minimum the amp handles that way all the power from your amplifier will be used.

Sounds like the subs are blown with the voicecoils fused together which means the amp is/was seeing a dead short ( zero Ohms reisitence) not good for any amp. Disconnect the speaker terminals from the amp and see if it turns on. The funny smell might have been the subs blowing up, i'll keep my fingers crossed for you.
