i never knew a rockford T2 was entry level....

how about L7s or L5s any thoughts on them?

 

Ive got a 12 l7 ,ported @32hz and it rocks the sheet outta my car.
Giving it 700wrms and not sure why people say they sound bad?? ive got no compaints.

 

For the price I would definatly go with L7 still one of my favorite subs
Re SX another great sub high efficiency

But if u want the best sound ImageDynamics IDMAx v.3 gets loud and clean
Adire Brahma , Boston G5

I have own all of them and i give them all thumbs up

 

sticking to his price range , he should have no problem picking up a pair of RE SE 10's for $600+tax

and definatelly will make a huge difference from one sub to 2 subs especially if you are only running your amp right now at 20 ohms ... in theory should gain 6 db comparing 2 10" with 1200 watts to 1 10" with only 600 watts

usinfg the box design I mentioned that thing will make you feel like you wanna shiet your panmts
