Got out for a couple of hours this weekend, RF300x2. + boom frt. seem to work great, but have nothing to compare it to, clear until about 75mph, still thinking of what a pair of 150w x2 speakers and turning amp up more than a 1/4 would sound like, any suggestions would help Polk mm651? Kickers, J&M's ?

 

I have the PBR 300x4 run'n a pair of Rockford Fosgate T-165's. I was actually plannig on doin a pair of 6.5s n lowers as well but there is no need. Very Very loud clean clear sound. So I can tell you amp is great As far as working with te 2ohm Booms I'm not sure. I think the 300x2 is 2 ohm stable.
