depends on what you want. all i get out of the pdx series is compact and style. i would not worry about it if your not to worried about space. theres plenty of other 1000 watt amps that put out there rms power for half the price. save your money
its sq lol not sql and theres better sq amps foe the price talk to a sq guy i would say do all sundown amps more reliable and better all around and sundown has super clean signal
