How do you turn bridge mode on mtx thunder 8302 amp

SOURCE: MTX Thunder 8302 Car Audio Amplifier

could be bad mosfets or outputs, needs replace

SOURCE: i have a mtx thunder 7801 and a sledge hammer box

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.

Ya. Just hook one sub to your amp (bridged) and hook the other sub (positive and negative) to the first subs positive and negative
