hey guys!

ok, ive just installed a new amp for my subs (3 Infinity 1220 12"). The amp is a solid audio F11D, stable down to one ohm. my deck has only one preout, so i have two Y splitters to seperate it and go to each amp (one for my speakers too). my speakers sound fine, but when i turn the subs on (i have a switch in the remaote turn on) the subs are very quiet, like the are only recieving 10 W, and there is a high pitched noise, that does NOT increase as i pres the gas. what could be wrong?!

i though maybe:

-i only have a 60 amp fuse in my power wire for an 1100 Wrms amp and a 350 W amp BUT would the fuse just blow wwhen i turn the subs on instead?

-RCA's BUT the speaker amp is fine, and the Y splitters are at the end of the RCA's, close to the amp.

-the gains are wrong BUT i played with them for a while, nothing, the subs put out nothing practically.

-this is my first amp with a remote bass boost, its not hooked up yet, it doesnt have to be does it?

THANKS SO MUCH FOR ANY HELP!!!

How did you wire the subs? If you did it wrong they might only BE receiving ten watts.

the fuse is fine, its only purpose is to protect the wire from igniting.

swap the RCA's from your mains to your subs and see if anything changes. You might need to plug in the bass boost remote, and you also need to play with your crossover crontrols.

If the gains are wrong... duh fix them. Fix everything thats wrong.

the subs are all single 4 ohm coils, they are wired in parellel, i know its not that.

i'll try the RCA's and the bass boost. could it be anything else?

thanks a lot for the help
