New guy here. Am 37, looking for a solid subwoofer to add to a new Hyundai Sonata,mounted in trunk. Probably looking for a 12" to 15" more than likely single subwoofer in a enclosure. Don't want a 'monster' box,just something with tight clean sounding bass. I don't listen to rap so I don't need that ground rumbling boomy bass. I'm more jazz and rock, so I want a sub that can really rock,can get down to 20 or so Hz and can kick me in the back pretty decent. I'm going to have 250watts into it from a JL 500/5 amp. I don't want to spend anymore than probably $250 or so and I DEFINATELY don't want junk;something that colors the music with it's rattles and flopping around. What's a good sub for this,any ideas? I've heard JL subs are good. 'Back in the day' JBL were darned good subs,are they still? There are soo friggin many subs out there, I really haven't got a clue. Is bandpass the way to go? I want the trunk to still BE the trunk;don't want this thing taking all the space. Just a smaller box with lots of punch and control to it. And I've also heard I should vent it into the passenger cabin via the port through the rear deck. Any opinions here? If it HAS a port that is.
