i had a 400w crossfire amp.. it's 2-channel..

but i want to change it to 4-channel amp..

the amp only hooked up to the 2-15 kicker subs..

so.. i want to use 4-channel amp to hook up to speakers too..

(i have mb quart front,rear speakers)

so.. what i want to know is...

what kinds of amp should i get??

now.. i'm looking for JL 300/4 ... is that ok??

what do u guys think??

and.. also tell me the price of amp too..

thanks a lot!
