I was thinking about getting either the MTX thunder 801D or the 1500D but i didn't know if the 1500 would over power them...it is rated at 750 X 1 at 4 ohms...the subs take 800 rms.. 2 MTX 8000 10's...and i didn't want to underpower them with the 801D b/c it is rated at 400 X 1 at 4 ohms..What does everyone else think. Is the 801D to little or is the 1500D to big?
An 801D will power your subs perfectly, 1500 is pushing your limits. I think you're looking at the peak rating, the MTX 8000 10" subs are 400W RMS, at a 2 ohm load an 801D is perfect for them as it'll give each sub 400W RMS.
