Please help me with subwoofer's, boxes, and amps!?

Question

Ok so here are the subwoofers i want to get : either the infinity kappa perfect 12.1D or the rockford fosgate T1's!

The amp's i want is either the MTX 1501 class D amp or the rockford fosgate T10001bd amp = both being mono!

and also what kind of box should i get enclosed, vented, back slanted, front slanted????

And also if you like the infinity subwoofers better witch amp should match it, and visa versa with the rockfor fosgate subwoofers!

THANK you so much!

Answer 1

infinity's have a nice sound to them, but the rockfords are badass and will deffinitly pound harder.i perfer a sealed box it sounds alot better. as far as the amps go...well there both great amps as well. the mtx one has more power then the rockford. but the t1's need the power. cause there rated at 600w rms.well thats that for my opinion

Well, it depends on your needs.  The Kappa Perfect is nice because it has variable qts, but for the normal user, that isn't going to be much of an advantage.  I have had both of these subs, and I must say that I enjoyed the RF significantly more than the Kappa.  The Fosgate has much better low-end extension, and it seems to perform better in a ported enclosure than the Kappa did.

As far as amps go, go with the T1000.1db.  Fosgates are known for being ridiculously under rated as far as power goes, so if your car runs 14.4 volts, that amp will most likely  do 1200+ RMS.

I would recommend going with a nice ported box for the RF, but you will need to have it custom made.  Very few manufacturers make boxes designed to work with higher end subs because they generally need an enclosure larger than the standard 1.25 cu. ft. design.  If you go with kappa, you'll probably want to go with a sealed enclosure, with the correct internal volume of course.
