I used this amp for a can less than a year, I sold for use as soon as I fesais I n'tais not satisfied.
I pulled four Subwoofers 400Watts RMS, and ca not typed.
Fullrange speakers on this amp should be sufficient but the bass is average.
Other than that it is very good equipment (filter, connector, limiter, etc.).
I have a crest CPX1500 since 4 years which is practically the same production that the PV SERIES and I have never had a problem, so any level reliability problem.

If I had to buy a low end amp I would not take this one but rather a brand recognized moin moin was 200euros chre.genre phonic, or HPA Thomann.
