Profiles have never "put out" like they say they do. I've had some friends that got them to replace older amps. One guy replaced an MTX 350watt with a Profile 500watt and the MTX hit harder and louder.

We didn't think that was right, we took it to a local auto/audio shop and asked them if he could test the output. Benched the MTX at 352watts and the Profile at 360watts. It's more, but not nearly what was advertised.

Personally, I have Infinity amps for both my subs. They are rated at 400watts, same shop as before did the same bench test for me and said they are doing about 410watts.

I always try to stay away from no name brands... like Profile. Who really makes them? I don't know. If it's actually a company named Profile, I've never heard of em.
