It's not recommended. Get yourself a better, Class D mono amp that can produce what you need for that pioneer sub.

A model number of the sub would be helpful for us to give some amp recomendations

so its not recomended or it wont work or it will blow my amp or what?? i havent got enough money to buy a new amp like u are suggesting. but if it will destroy my amp ill hafta buy a new one anyway.

im not sure of the sub model number, it is a 800watt sub that came in a pioneer box. its a sealed box.

you wont be able to do this, your 1 and 2 channel will be producing one signal and your 3 and 4 channle will be producing another, even if your amp lets you hook this up to one sub (more then likely it will go into protection) it would be harmful to both your sub and amp..whatr happens when you connect your 2 bridged channels is the power from 1 &2 try to go to 3&4   it would be just like taking the +speaker wire from one channel and running it to the postive speaker out put of another channel
