need help with sub, not sounding right

[Johnston_2007 10+ year member]

i have a kicker 12" l5 dual 4 ohm and im powering it with an eclipse 3322 amp. i thought the amp was pushing out 664 watts x1 at 2 ohms but discovered its only pushing out about 350. but my question is sometimes like when i listen to rock songs like afi and other bands of that sort the bass is off and sounds kinda mushy and i dont like it. its not tight. my box is 4 cubic feet and ported to 35 hrtz i belive. its 34 inches long 18 inches deep and 14 inches tall. the port is 3 inches wide and 14 inches tall and goes back 13.5 inches and has another piece that goes over 14 inches. if i got a bigger amp to supply more power woudl that make the sub not so mushy? or should i make the box smaller or what. thanxs alot -andy-

IMO, you got too much air space for the music you listen to

I'm not saying ported boxes arent right for rock songs but between my sealed shiva and my ported sx, the sealed shiva kicks ass with rock songs(especially with AFI //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif).

I would look at sealing your sub in a medium to large enclosure with some polyfill stuffed in it. Those subs will not be the most accurate in a ported box that size tuned to 34 hz.

thanxs i will have to check into it. right now im looking at a diff. amp such as the diamond d51200.1. and i will see how that works out. and usually i listen to rap music but sometimes i listen to rock and music such as the dave matthews band. and stuff like that. but i built the box to kickers's specs for an spl box.
