is my amp powerful enough?? Please help

[sanjayfernando]

hi

i got 2 amps, one 4 ch SONY amp for running the front and rear speakers (Pioneer) and a BOSS 2ch amp(bridged) for powering a 700w, 10 inch Pioneer subwoofer..

the head unit im gonna be using will be a pioneer DEH MP8600 MP

Now, the problem lies in the fact that i bought all of these, here in australia, where as i am hoping to fix em to the car i have back in my home country (Sri Lanka)

I am having doubts as to whether the amps i am using will be powerful enough to run the subwoofer... here are the specifications..

Note that i dont mind fixing the sony amp for the sub if that will solve the problem.

Sony amp

______________

500w

max output :

4 speakers - 100w x 4 (at 4ohm)

It depends on the sub...

you said 700 watts, RMS or peak, what's the sub quality, sounds a little overrated.

Well, with the 8 ohm sub, your gone reduce you amp's output by half, The sony's 1 channel would pump 125 watts @ 8OHMS, and the boss would be at 90WATTS @ 8 OHMS. So, my opinion would be use 2 8 OHM subs, but you probably don't have another one of those 8 ohm subs, OR You migh get better results by purchasing a nice 100 true watt RMS 4 ohm sub.

Good Luck
