Is it possible to use a 4 channel amp for comps and sub?

[osm0nd 10+ year member]

Hey I was wondering if its possible to use a 4 channel amp to power my comps and sub? I have a set of SLC's and a JL w6. I was going to get a 2 channel amp for the comps and a separate amp to power the sub. But i'm really trying to cut down on my expenses so i was wondering if i can bridge the other 2 channels to power the sub instead? Is it possible? Will it sound okay? Help me please...

yes you can as long as the impedence isn't too low bridged on the rear channels.

Remember that when you bridge an amp, each channel sees half of the impedence.

Just make sure you set the crossovers correctly and you'll be good to go

Yes I am currently doing it in my truck. front 2 channels running components and the rear 2 channels bridged to a single 10 at 4ohms.
