Question about wiring my amp...

[nickster914]

Ok i really need some help here, try to stick with me haha.

I have a Kenwood kac-9102d amplifier, powering a 12" kicker L7.

The amp puts out 500 watts rms at 4 ohms, and 850 watts rms at 2 ohms. The kicker runs at 750 watts rms. I had this set up in my Saturn Ion Redline wired to 2 ohms and it BUMPED! Heres the problem...

I put my Redline away for the winter so i figured i would put the amp and sub in my Saturn Vue for the winter. I have it all wired up to the stock radio and it works perfectly until i turn up the volume quite a bit. The thing is that i used a lower grade power/ground cable that i thought would still work in the vue. When i turn up the volume it works fine until there is a big hit of bass and then it cuts out and the light on my amp turns off for maybe a second or two. It does this everytime the bass gets loud. I think its protection mode but i'm not sure. I really dont feel like buying and running new wire. If i wire the sub to 4 ohms will it not cut out as bad? I want it to be loud like in my redline. I'm not sure it's the wire but i dont know what else it would be since its the only thing thats different from the redline. Will a capacitor help? Is there a better way to wire the sub? Any help or suggestions will be appreciated, Thanks!

Heres the difference in wire...

your voltage is dropping, bad.

Wire should be fine for that amp...check your grounds and connections

Connected the ground to a new spot, didnt make a difference. I'll try it again...

Any other ideas???

sounds about right.

could be wire though. i had this problem once.. and it got fixed immediately after i upgraded from 4 gauge to 2 gauge

but check all other things bfore you go get new wire

Somebody also said, "If the radio cannot supply enough signal the amp can't get a grip on it and crank it up. (All has to do with gain ratios).

Sounds like the radio isn't giving the amp a large enough signal."

Could this be the problem?
