Ok I purchased a new car and am taking out my old audio (which won't fit into the new car) and trying to purchase some new stuff (or used) for my new car. Now I have about 1.3 cu ft of space to work with for a sub... Not much at all but I want good SQ that can get LOUD.... I listen to Rock, Rap, Hip hop, Techno, etc.... Now I really like the 12" JLw6v2 which I would do in a sealed enclosure but I don't know if I can justify the HUGE markup they put on the sub... I know it is a great sub and it sounds great but I'm sure I can do just as well for much cheaper.... I also like that the sub can run off 500 - 600 rms and get loud This is where you guys come into play... I am trying not to strain the charging system on my new car too much it is a rx-8 (2007). So keeping it to lower power while keep the loudness would be nice... The other options I have looked at are FI Q 10" Ported or FI Q 12" Sealed (not sure which would get more more spl.... or if its a toss up and which would sound better) The only problem being that the Q requires a decent bit of power to move it... Also looking at the FI SSD 10" Ported or 12" Sealed... which take a little less power but I'm unsure if I would be better off with the Q? Now my old gear for reference was a 15" RE XXX (Older 2004/2005 model) in a sealed enclosure being fed with a PPI Art A1200.... I cant fit much large then a 12" sub though in my new car and this is not going to work at all because of size, weight after its all done, and eats more power then I would like.... I could possibly stick with the A1200 and use it on my new sub but I am open to other amps as well... (1200 watts being a bit higher then I might aim for usually but it saves me from getting an amp I gues... Id try to stick to closer to under 1000 watts maybe... also this PPI ART I believe is a class A/B amp so its not really known for efficiency!) Now I am trying to sell my old gear to get my new gear so its not too har don the pocket... I am aiming for maybe 300 for sub and 300 for amp but if you see something much better that isnt too much worse in price id be interested as well... These prices are just suggestions/guildelines... I dont want you to suggets a 600 sub but I wouldnt be opposed to going to 750 or more for sub/amp if its worth it... Daily driver type setup... not a competition setup
