ok. to start off i have an 09 silverado crew cab with 2 sundown 10's in a prefab ported box on my back seat. (1 is a sa 10 an the other is an e10. i didnt buy them new, got em both for $150 from a freind an they were not even fully broke in yet) they are runnin off a hifonics gladiator 1400.1 amp at 1 ohm. well yesterday my e10 seized up so i think im just gonna rebuild my system -the amp. this setup had a nice thump to it an it outdid all my freinds systems (which really isnt saying much) but it was a more "hear it not feel it" type system. i want a heart pounding system now. i was thinkin maybe either 2 12's or 1 good 15. any suggestions?i wanna keep the price down tho to a max of about $200. ive kinda been lookin at rockford p2's or one p3 15. any other suggestions?
