Lay down Sally...

Sure can! From classic industry, I got the better ones but they make one with no speaker or a 80 watt speaker as well. Mine are a 120 watt made by pioneer. I figured go with the upgraded speakers since I'm only running the 4, should help make the sound better but not enough to ruin the exhaust.
