Ok Now that i have a vehicle that i can put a decent amount of subs in im ready to throw together a vehicle that thumps. I have one amp that im not using right now its a rockford fosgate bd1000 it puts out 1109 (according to the birth sheet) @ 2 ohms. I was thinking 4 18s wired to 2 ohms...be a lil over 250 per sub. I will need to save for a while but in the end it will be either 4 18s, 8 15s or 6 18s. I want to be able to hit 150 atleast. In my old jeep with 9 15s i ran one 1001d and hit 153.5 which is pretty good considering we used one 1000 watt amp. Any suggestion? I like the sound of sealed boxes but most 18s i hav heard in ported boxes slam. I was thinking of running the RF Punch ( or whatever they call em now) 18s. Any miscelanous info or suggestions are welcome.
