Ya I mentioned the PG cause you already have a whole system with PG. Like someone said earlier 1000-1500w rms something beefy, a Memphis, Mmats, Earthquake, USamps, American Bass, Orion, Zapco or something of that nature. These guys usually rate there amps at 12-13.8Volts not 14.4v so you really get the power you are paying for.

 

which generation of brahma's are we talking about? impossible to make suggestions without knowing

 

I'm using the MK2 Brahma.

Hardwrkr what do u mean by switctchinh over...I am keeping my exact setup but just wanted to add another sub for more Rumble. Like stated b4 this sub will only be on for when I want mass bass via a speaker selector.

 

Using a different driver/enclosure to cover the same frequency's as another is unpredictable. It's best to build one system and tuen it to what you want it to do best. If your current PG Ti's are giving you the SQ you want but are lacking in output well there are lot's of great drivers out there that can give you as good and better SQ [I]and[I] much more output in the same package.

Are your Ti's ported or sealed? If your running them sealed simply switching to a ported enclosure may give you the increased output you desire while retaining the SQ if done properly.

Or if you really want it to ****, try a pair of 15's designed for excellent SQ and output. A pair of OZ Matrix Elite 15's, a 1500-2000rms amp to run them, and a ported enclosure could easily achieve beautiful SQ (IMO a much better sounding and performing driver than the PGTi) and with enough output to take your head off if desired. Plus, compared to what you're currently planning, is less wiring, less space, and I'll bet my *** that it would have better SQ and more output (and the results are predictable).
That's just one example as I can think of a few drivers that could give fantastic results and won't break the bank.

 

the MkII Brahma's can reach full excursion at around 1kw in a Qtc .710 enclosure.
