I ended up just going with a sundown 100.4 and I am going to end up bridging the amp and it's rated power is 320 rms when bridged. I know the question is highly subjective to what kind of music you like ect. I listen to bit rap and rock so I would like something that sounds good but I really don't want to spend more than $400 on a set. I need them to loud as well, I am going to be running 2 custom 12's with 2 sundown 2500ds strapped to them. Any suggestions? I don't plan on running rear fill. This is just my first setup in 3 years a lot of companies of come and gone and the ones I recognize have all kinds of lines I don't know the difference of.
