i have 2 amps i got dirt cheap, both exactly the same and i figured they are better than head unit....more power for 6x9s they are 2 optimus 55wattsx2 amps they are not normally bridgable (no button, etc) can i safely bridge these to run my 6x9s with out seriously hurting the amps? if so how? thanks for the help

 

Do the amps say if they are 2-ohm stable? Modern amps don't have buttons for bridging; it's all in the wiring.
