I currently run a treo ssi 15 giving it about 1100 watts and at first it was loud but over time its begining to fall off. What sub can I put in its place on the same power and get louder? Sq isn't really an issue, but please no one note wonders. 15" or 18" probably since my trunk is huge( 85 Cadillac Fleetwood), unless you know something I don't. Please try not to go outrageous on the price though. I hear SX's are good, but I've never heard one so I'm not sure. LMK what you guys think. Thanx
