I'm about to order a re xxx 15".. And I was PLANNING on ordering another Hifonics brutus amp that was rated about 2500 rms. But I did some searching on the Internet and they seem to b a good bit underrated so I would have to get like a 3500 rms Hifonics amp to give the xxx prob round 2500 roughly by as I'm sure y'all know the xxx will take more than it's rated 2000 rms daily.. So I wa wanting to know an alternative amp I could get to give it a solid 2500 rms at times.. But i dnt really wanna spend much over $300 on an amp.. Thanks for all opinions..
