you may not NEED it

but you sure should WANT a seperate amplifier for your sub!

hey dont get me wrong, i know you know your **** but i must say this

running mids and a sub on a 4 channel amp is possible, but will ONLY sound good if you split the channels on a crossover and tune the bass side differently from the mid/high side

i do this on my 2 chaanel amp with y-splitters, so its not only 4 channel amps that can be used (i have a 2 channel amp that plays 4 speakers perfectly ) so splitting them would be a good idea if you want it to sound good

of course alot of 4 channel amps have high low pass frequency etc etc to tune the 2 channels differently, but imo not many of them work well

seperating the channels on a crossover is like having a seperate amp for bass

Dude - what the **** have you been smoking.....

BTW, he'd be getting 200W to the sub - assuming it would present a 4 ohm mono load to the amplifer
