ok, I finally bought some speakers for my FC...and i'm not sure what kind of amp I need to run this setup...

right now i have
(2) 4" Infinity 452i speakers for the front
# recommended power range 2-35 watts RMS
# peak power handling 105 watts

just bought
(2)6.5" Infinity 652.5i speakers for the rear
# 75 Watts Power Handling
# 225 Watts Power Handling

and I plan on running
(1) 12" sub...dunno what kind, probably an infinity sub. lol

so when i look for an amp..what do i need?

 

Any good 2-channel amp, 75x2.

Depends on the sub. How much power can it take?

 

I heard I'll need a 4 channel amp...to run all 4 speakers?

 

Depends on what sub you get and how much power it needs. If you buy a 12" sub that needs 500W, and you have a 75x4 4-channel amp that nets 150W when you bridge 2 of its channels to it, then it's being unpowered. It'll work, but you don't expect the sub to perform anywhere near what it's capable of. If you're going to run a big sub, run a big dedicated amp to it.

 

i've got an infinity mono amp that would be perfect. and its near brand new...

its a infinity reference 310A 300 watt mono sub amp...

i'll sell it for $125 cdn

 

My pot on the speakers has just gone bad on mine and it looks like a complete replacement due to the common ground system that they put in.

Nick - check your e-mail - sent you a couple about the headlight washer.

 

What Brand /model (headunit ) do U have? If your planning on Putting a 10 inch sub....Just power your(highs) 4 car speakers W/ the internal amplifier(radio)
and yeah a 150 watt amp is enough 4 a 10(decent amp of course) JL,Alpine, Kenwood, phoenix gold
