I have a 10 inch square solo-baric kicker subwoofer it came with a 350 watt kicker amp. Im looking at getting new mid sound speakers, for starters is my 350 watt amp putting out enough energy for my subwoofer, and if i want to run my new mids (5.25 round) into my amp what size amp will i need, or can i put them into my current amp. thanks
