Very good info, its odd, i see alot of crappy amps being sold for way too much, nothing new, however, Profile seems to make good quality stuff for as cheap as it gets. I run the CL800 for my sub. $100.01 shipped. Signal / Noise Ratio- >105db Total Harmonic Distortion->0.05% Bridged RMS at 4 ohms- 600 watts and 2 30 amp Fuses. Any one see anything really wrong with theese amps? I am really impressed with them, and am about to recomend them in my next amature install.
No, I have seen decent results using Profile amps as well. Their efficiency is a bit optimistic on that amp. I get 69.4% efficiency. I would say a little bit of derating is in order, say closer to 500 to 520 watts on an RMS basis.
so if i got a 4 channel 2000watt amp and i had 2 800 watt subs , would that work? can i use more subs?
It would really depend on the hardware... What amp? What woofers? Sealed, vented, bandpass, TL? We'll need TONS more info than that.
Generally speaking though, you can run ANY amplifier on ANY (number of) woofer(s), so long as power handling is not exceeded (read: PROPER level matchings), and the amp is not overloaded. ___________________________________ It all reminds me of something that Moliere once said to Guy de Maupassant at a cafe in Vienna... That's nice. You should write it down.

always remember the peak power means nothing i went to a large sale advertising "1000w amplifiers for 100 bucks!"
they were pyramid giant ass looking things, no RMS or any actual specs arround the thing, had to get a guy to open the box to find out that this "1000w amp" was pushing 20w RMS on 2 channels, funny consittering my 'lesser amp' from walmart to push my 5.25s and 6x9s is a 4 channel amp with 50rms on EACH channel. so remember children, RMS, love peak power! ___________________________________ 97 Monte Carlo

Hae, you know I love you... Wow, its been many months and I come back to see this wickedly nice read. Thanks for making time at work actually informative! Anyways... Very wonderful read and you certainly deserve the certification thing under your name(cool as heck idea).
And he was saying simply that your amp may not be capable of its listed power. Just try and find a RMS rating number for it. If there isn't one of those available than one of the guys can explain a better way to try and figure it out. I just wouldn't rely on it, my personal opinion though.

FYI, the rating on the Pyle PLAD413 is 200 watts X 4 channels @ 4-ohms. It appears to have 2 20-amp fuses, so the actual usable capability is probably more like to 50 watts per channel. There is no way in the world that amp can produce 2000 watts, period. ___________________________________ Support the12volt.com
