hi i was wondering if the ascendant audio atlas 15" came in dual 2 ohm configurations? now evben though they are 300 watts rms will they still get loud? i was looking into getting 4 15" atlas's because #1 they are so cheap...and #2 i already have an alpine mrd m501 which is putting out around 600 watts R.M.S. at 2 Ohm. so i thought if i run 2 atlas 15" to that amp and picked another one up that should get pretty loud but do you think with only 1200 watts rms those 4 subs would get loud? im not to sure but if anyone can help me out that would be great thanks.
