Is there anyway to bridge 2 amps together to get a 'combined' output? would I need to buy a crossover or something like that in order to do it or can it even be done?

 

There are some high power class d amps that can be "strapped together" to combine power but, they are mainly for extreme DB contests. Not just any two amps can be combined. They have to be designed for it. Hope that helps.

 

Pretty much what he said. What brand and model are the amps? And is the sub a DVC?
