Audiobahn amp 'pwrs' Up no Sound
 
I have a Audiobahn A4801T 4-channel car amplifier it was bridged pushing 2 "10' Audiobahn 105 T SUBS bridged i had not problems for weeks until it started to go into protection mode.

I went and check all the connections and found that there were 2 resistors were fried on ch's 2 & 3 right next to the transistors located on the heat sink on each side i

So when i power up the amp it turns on but when i connect my speakers they get nothing
and when i connect the to ch 2 + and 3 + they pop so i checked them with my Multi meter and found that those 2 ch have 19.04 volt going threw when the others have 3 - 40 volts so i imagine that is why they pop when i try to connect them

what can it be?
