Hey just doing some window shopping looking for opitions for my amp hoping to ad Fi to my list I'm not looking to buy soon and I know alot can change in a company's line-up over a year but I treat car audio like my version of a fantiacy football league and I'll do builds in my head waiting to hit the lottery or my kids to graduate so I can have more toys... How I like my bass... Loud, Low, & Clean as posible I listen to just about everything but mostly rock and rap Car... not positive leaning toward a smaller hatchback like a honda civic or mini cooper, either way the space required for humans can be limited to the front seats and enough room for a suitcase for the weekend it will basicly be a toy daily drivin and most likely not go to many compitions. Past subs: Hollywood (2 - 10"), Kicker Impulse (2 -12"), Rockford Fosgate Series 1 (2 - 12"), Kicker SoloBaric (1 - 12"), SoundStream SPL (2 -12"), JL audio 10w6 (3 - 10"), Kicker XPL (4 -12") Last used & current owned sub: Rockford Fosgate Power T1 ( 1 -12") housed in a 3cu. ft. ported box @37Hz in a 2001 Hyundai Sonata Amp: Mmats D200HC 1200wRMSx1 @1ohm.... but as tested by CA&E the year I bought it puts out 1325w @1ohm @ 12.5v I had origanlly bought 2 T1's and had them in a sealed box (had never owned a ported box) but wasn't really impressed with them. Not wanting to give up all my trunk space at the time I ported just one of them... WOW!!! So much of a difference I sold 1 of them. But only running 1- T1 only gives me a 2ohm load so I'm not using my amp to it's full potential (only pushing about 900w) which is why I'm looking at subs. So would any one here be able to compair Fi's to the Rockford Power line? I've decided if I'm going with a single sub I want to go larger so a 15" it is unless an 18" can keep up and not sound like ass when playing rock (Metallica fan) and if I would have enough space for such a HUGE box. I'm Guessing the BL line is what I should be looking at? I like the stoutness of the BTL's but I'm worried about not having enough power since thier RMS is 2000w. I've seen people kill good subs trying to push a amp when they didn't have enough power for a sub and it started clipping. Is there a max power rating for the BL's? Opinions, Comments, need more info?
