i could blow 2 type r's away w/ one of my pr12's in a ported box but my friend has 2 10in. pioneer premiers in a ported box and they slam so yeah good setup and hifonics brutus amps are good for the money
they are budget subs plane and simple. they can beat many things but many things can beat them... Of course it's all in the box your equipment is only as good as you build the box.
Forget about the rear fill, don't use the TB subs in front and other ones in the back, sell the CDT's and buy something that actually has midbass, and for god sakes spend some money on deadening.
I've heard great things about the CDT and they are actually going to be my next set. but i second the whole no rear fill after making a post about it a couple weeks ago, i ever knew why people did it and how many there were. once you get used to it you'll love it.
hmmm im not going to have a rear fill when i first set everything up, but then i guess well see what happens because people do ride in my car and it would be pretty lame to have no rear fill then
