Alright so i think im having a problem with my subs because whenever i turn my car on, and it only does this sometimes, like it doesn't always do this, but you can hear like the subs going "brrr" like the car, and when i step on the gas you can hear it go up like it's echoing the cars tone but through the subs...does anybody know how i might be able to fix this for relatively cheap because i'm on a tight budget.

thanks

 

Try moving your ground, if that doesn't work get a ground loop isolator. If you have to get the GLI, they are not that expensive

 

First check all wiring.. especially your sub-bass amp's gound.. the ground has to screwed onto bare metal.. no paint whatsoever.

The ground wire should be no more than 8-9inches from the amp if possible. The ground location must be car chassis metal.. not to a seat bracket, etc.

Next thing after ground is RCAs and power wire.. they must be seperated by at least 12 inchs or so... if they must cross have them cross " _|_ " <--perpendicular to one another.

Try moving your ground around..this should clear up the noise... I tend to stay away from ground loop isolaters.

So issues to check... (1) ground wire location, connection, length (2) RCAs.. shielded?, bad quality..worn? (3) RCA and power wire prximity... keep far apart as possible..

 

yes it sounds like a wiring is done sloppy.

i too stay away from ground loop isolaters, or use them as a last resort. dont they work by lowering your voltage? not something i would want.

 

OK thanks guys im going to re-rout my ground, i'm hoping it's just the placement of where i put the ground and i used a screwdrivers to get rid of all the paint and everything before i grounded it; however, i just relocated my amp so im sure i can find another place to ground it..i'm gonna try that and let you guys know what happends...
