The p1's, are pretty sad, but the 2/3's, and even the power series is ok. Personally, I don't like the JBL's, go with Rockford's.
i have a RF T1 12" sub (power series), in my camaro, and ive heard alot and my 12 hits HARD. I dunno about the JBL's they may be better, so i dont think you can go wrong with either one. If u go RF, DO NOT get the PUNCH series (p1,p2,p3) go straight to POWER, and youll be satisfied.
Ya, but for the price of the power's, you can do better.
you can find T1's on ebay, brand new for around $285-$300 which retail is around $400. If u want another brand, go for it, im just givin ya my input on fosgate, and maybe help ya and save ya a couple bucks. I think all brands, except for boss, pyle,pyramid etc are all good, you cant go wrong withthose, its just your speaker choice and how loud you want it.
