Why aren't my mids and highs amp playing?

[Zingers]

i disconnected my car battery and put a new piece of wire(same gauge wire as before) that leads to my in line fuse and when i got my battery all hooked up again the mids and highs were not playing. my other amp was unaffected by this because it was playing the sub woofers. i check the power with my multimeter and its getting the right power to the amp and the amp itself is lighting up but not playing.

It was playing before i disconnect my battery but when i hooked it back up it just poof stopped working.

i check the in line fuse didn't look blown even put a new one in it, check the fuse in the amp itself and they look fine

Any Ideas?

if it helps here is what i am running

performance teknique 1500 for the Kicker CVR Sub woofers
