I'm currently in the market for some new subs.

As of right now I am running 4 Kicker L7 10's
Power is from a pair of Kicker KX1200.1's strapped making around 2.8k
Box is 5-6ft^3 sealed.

Ideally what I would like to do is drop down to a pair of 12's or an awsome single 15"
I'm looking for a great SQL driver, I want to be able to pound out the bass, but still be able to enjoy the sublties of the music.
Current drivers I am looking at RE MX12, DD3512, DD9515 etc.

Vehicle - 2003 Nissan Sentra SE-R SpecV
I am doing consistant 143-144dB
I'd like to get closer to the 150dB range

What do you guys suggest I do?

 

get an 18"

 

A ported box for and 18 is going to be massive
not to mention i won't be able to rear fire it as its too tall

 

Change the box. You've got capable subs already. Although you could put more power to them I would suggest a new enclosure first and see where that gets you. Ditch the sealed design.

 

Your box is WAY TO BIG. Those subs need to be in a 1.25 cube box each PORTED, tuned at about 34hz, it will be LOUD and play very good.

 

try porting your current setup

 

Personally I like sealed boxes more, for listening to music. I believe it sounds more crisp and clear, but thats just my ears. Maybe building a box to spec might work.

 

yah those subs love a smaller ported box! build one they will hammer

 

orion subs are the shiznit

 

but sealed soudns better
