[TRAP$TAR 10+ year member]

i have 4 10inch kicker comp cvr and a hifonics 1200 2channel amp everythings wired correctly just re wired it and it still does it.... the subs will work when i crank the bass knob and everything but once i turn the volume up to around 30 they stop working and just start making a vibarating noise like verrrrrrrrrrrrrrrrrrrrrrverrrrrrrrrrverrrrrrr not that loud but they deffintly arent slamming like before. also i have already grounded the rca's on the hu once before and thinking this was the problem i re grounded them and it still does it and yes i have a pioneer hu any suggestions please please please

assuming by your avatar saying "breakin glass" Im assuming youre bumping so loud with those kickers youre busting your windows? You got a caprice? Or a Deville?

About the problem youre having though - try turning the gain down and see what that does. And most 2 channel amps wont handle a 2 ohm load bridged and will cut off when you turn it up. Run 2 subs on each channel at 4 ohms (the vc's wired in series, then parallel to the amp) thats your only option.

thats how there wired there all in one sealed box and the 2 subs are wired to one channel so i have 4 wires comming out of the box 2 negative and 2 positive and then i have them each going to there own channels its not bridged

You know how to use a multimeter? Check the ground youre using. What kind of car is it

i guess its time for you to get a bigger and stronger amp to power those kicker's the way you want them to sound:laugh://content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

havent you ever heard of hott boxing and why would i do it without some music hahaha but the amp will turn on with the headunit with the key slightly turned but the subs wont hit at all i have to put a dmm on it see how many volts im running

check for phase. frequencies could be canceling each other out

when i crank the bass knob and everything but once i turn the volume up to around 30 they stop working and just start making a vibarating noise like verrrrrrrrrrrrrrrrrrrrrrverrrrrrrrrrverrrrrrr not that loud but they deffintly arent slamming like before.

Turn the bass knob back down to zero. I think your clipping the hell out of your amp input stage. The subs are getting only heavily distorted sound.

Bass knobs (eq boost) should be outlawed. They serve no purpose, only generate distortion.

adjust your gains properly before you blow your ****

Not all bass knobs are bad //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I specified eq boost knobs. Gain controls are fine. Eq boost is the ****.
