I'm running 4ohm SWS under the front seats wired in parallel on one of the channels, and the rest of the speakers are 4 ohms each.

It's fine 99% of the time, but I have good quality speakers up front (rainbows) and they sound absolutely cracking when I really turn it up. Frankly that type of volume levels are much higher than stock, and imtnk the PDX is rated at 50W so maybe I'm just pushing it too much? Not sure how to tell...

The amp gets warm but not burning hot. I'm thinking creating ventilation holes might help, or even stepping up to a small fan...
