Now I am not going to point fingers at us amps quality because it is probably me doing something wrong. Anywho, I have a us amps xt1600.4 runnning focal polykevlar 5.25" components. I have the focals in stock door locations with the tweeters mounted on the pillars. The xt1600.4 has a .5 farad cap on it. I have not yet fine tuned the gains because i have not had the chance but they are roughly set. I expected this combo to blow me away, but it is not any better than the old boston component set I had running off the HU. My question is: Could the gains need to be changed, I mean, can that cause distortion? also, I have some sub par rca's from scosche. Could that be it? Lastly I have Some of the speaker wire and the rca run nest to a battery cable which i know is not good. If i move them apart, would the sound be better? I plan on doing that anyways, I just have a temp install right now until I can get my pops to help me build an amp rack and a better box. Any help s appreciated!!

you bridged the 1600.4 right? i mean if you do your gonna get a crapton of overhead on those comps so you should be powering them adequately

also set the gains using a DMM. i personally like setting by ear but to every person thier own.

no. should i bridge it? that means the focals would see like 2oo watts a piece. Do you think they could handle it?

DO IT BRIDGED!!

just set the gains accordingly. i had my rainbows rated at 60w with an md41 bridged (180w)

remember set the gains accordingly.... you can never have too much overhead.

what kind of distortion are you getting?

Dont forget to set the gains accordingly because setting the gains accordingly will make it so you can set the gains accordingly.

Ohh ya

make shure you set the gains accordingly

oh and remember.... set the gains accordingly

i say that because people will blow thier speakers if they dont set thier gains accordingly

if you bridge it you can set the gains to recieve the exact power you want and give the comps the most they can possibly handle. that doesnt mean set THE gain to where they are jsut before clipping and expectthe comps to take it it means set them at the comps max which is probably higher then the unbridged output.

ok i lost my manual....how do i bridge them?

you need 2 y-splitters... they are .99+ shipping at knu konceptz.

then take the female ends of both splitters and hook them up to your original rca cables.... what you are doing is turning 4 channels into 2.

for the speaker leads, bridge them like you would a 2 channel... what i do is treat a 4 channel amp like 2 2 channel amps... it always makes things clearer to me that way
