Ok... when looking at amps, i'mi wondering if they're generally rated in RMS or peak?
for exampe.. the JBL BP600.1, is it 600 w peak or 600w RMS?
edit: i think until i can afford the new RE 1200w amp, i'm going to run a single SE12 or 15" off a jbl bp600.1.
those subs fuckin wang. theres a video on woofervids.com of a signle se10 in a truck... talk about boner.

good quality amps are usually stated at rms, cheap amps are stated way above the peak watts

well.. i know i'll be safe witha JBL 600.1
The re amps are so sexy looking. it'll be a great combo once i get this all going.SE12 or 15 in a big ported box, with the RE 1200W amp mounted near near the wheel well.

the power rating will be stated as RMS, or Peak/MAX.
JBL uses RMS ratings.
if the amp you're looking at doesn't specify the power rating as RMS or Peak, and at a specific load @ what % THD at a specified frequency range like:
500 watts RMS x 2 @ 4 ohms @ .01%THD 20-20,000Hz
then assume it's a crap amplifier and a peak rating.

a assume a lower THD would indicate that its RMS?

The 600.1 is 300rms@4 ohms, 600rms@2 ohms, and 600rms@1 ohm.
Now, I've actually blown the fuses on my amp. So they should mostly be under-rated.

lower THD just means lower total harmonic distortion. Cleaner output.
THD has nothing to do with differentiating between RMS and Peak.
