I did do some testing on a CT Sounds t1500.1 that my buddy had laying around. It is in that 200$ range that is a common budget. Wired at 0.5 nominal on my 12s.
Sealed legal- 148.6db
Outlaw kick- 150.1db
This is with drop to 12v, with just a pepboys g34 agm up front, so probably comparable to what the target consumer would I have. I'll clamp this weekend, but i can tell you its around 1000-1100w, with reactive about 1.2 or 1.3ohm. Pretty reasonable really. As far as tone burps, no complaints.
I attempted Street Beat testing. This amp would just not play. Protection circuitry appears good however.. various methods of play protected either instantly, or very quickly. So bummed out in that regard. Should be noted at that my reactive is very low, at 49hz where I was attempting to play, it is between 0.9 and 1.0. My rd3250 also protects on SB runs unless track is above 50. My rise is non existant from 44-48hz.
Compared to the rd 3250, Populous 6500
