How many watts is my amp putting out?

I bought an Xtreme amp today for $200. It sounds really great. No clipping or anything.

The question I wanted to ask is about how much power is coming from the amp.

It says

150WRMS x 1 @ 4 ohms.
250WRMS x 1 @ 2 ohms.
500W Max

on the website. http://www.directed.com/coms.asp

The reason I'm asking is that it has two speaker outputs, so there is no bridging involve (that I know of). Is it putting 150W to both my speakers? Or 75W?

There is no clipping. The guy at the car audio place said it would put 230W RMS to both my speakers, Like it says on the box.

"230W RMS x 1 channel @ 4 ohms."

Please help. Thanks a lot.

Well it cant vary well put out 230 WRMS x1 into 4 Ohms and 150 WRMS x1 into 4 Ohms...

Recheck the booklet/box/amp and get the correct specs.

That's my whole problem. It says 230rms @ 4 ohms in the book and on the box. On the website it says 150rms @ 4 ohms.

I guess I'm going to go with the 150WRMS. It doesn't seem to over-power the speakers and that's just about how much a 500WMAX amplifier should put out.

I've never messed with a mono amp before. Thanx again.

More advice would still be appreciated though, just incase I'm wrong.

in most cases, the RMS rating is should be around HALF of the max power rating. Not on the cheap stuff though like 5,000 watt power accoustic subs.

Wow, cant believe you paid $200 for that!

Thats .80$ per watt! ouch!

Take that thing back! Hell I seen an ARC KAR 400.4 for 180 new on CAF...

I think you would have better luck with the new JBL amps, cheaper also.

BTW cant tell you power output unless I know what Ohms your subs are. If they are DVC need to know the final impedance per driver.

If it's 150x1 @ 4 ohms and 250x1 @ 2 ohms and you have two 4 ohm subs, one on each terminal, they're in parallel for a 2 ohm load.

that's 125 watts per sub. (250/2=125)
