Ok. I have a PG X2300 that is 75x2 into 4 Ohms and 150x2 into 2 Ohms. If I want to run all four of my speakers on this amp what wattage will I get? I know that PG is any Ohm stable but I really wanted to run just one amp. I also have a Punch 360 and Punch 40. Which should I use?

 

You'll place the front and rear of each side in parallel for a 2 ohm load, giving you 150W per side.
