Guest Posted September 22, 2011 Report Share Posted September 22, 2011 my brother taught me to do it. on a crunch amp i got from him, the board was mounted to the metal case (he took it apart and did it cuz it was supposed to help cool) and it never had a good ground, so i grounded case and worked fine from then on. so since then, ive done to all my amps. all amps are mounted to the case that its inside. never ground an amp like that, ever. use only the terminals that are actually on the amp itself.

kam311 Posted September 22, 2011 Report Share Posted September 22, 2011 Yeah the 2nd ground is definately a problem! The electricity has to take a specific route through the board to function, you grounding the current through the amp case is going to completely fuck that route up. It might even shock your ass or start your car on fire! Any other special tricks in your wiring man? I'm worried now so far...

Sounds like you really need to be careful and read some more before you just start adding wires.... lower tuning is just hard. I was surprised how loud 145 sounds at 35hz, and how quiet 145 sounds at 50hz. -= 2005 Tahoe LT =-Head unit: Pioneer AVH-X5500BHSSource: iPad Mini in dash Subs: 2 T1 12's Sub Amp: T1500-1bdCPWire: Rockford Fosgate 1/0 awgSignal Cable: MonsterFronts:Stock Bose for now:)Rears: Stock Bose for now:)MIds/High amp: Stock Bose for now:) 2005 Tahoe Build Log: http://www.stevemeadedesigns.com/board/topic/172529-2005-tahoe-my-17th-vehicle/ 2001 Monte Build Log: http://www.stevemeadedesigns.com/board/topic/160030-2001-monte-carlo-my-16th-car-lol/page-2#entry25309381997 Tahoe Build Log: http://www.stevemead...oe-6-15-rf-15s/2001 Impala Build Log: http://www.stevemead...katzkin-inside/ Link to comment Share on other sites More sharing options...

pimpnFosgates Posted September 22, 2011 Author Report Share Posted September 22, 2011 no, just that one. other than that its normal. can second ground cause car noise to run through speakers, say a blinker noise when amps running and cars on?

Sounds like you really need to be careful and read some more before you just start adding wires.... i never had a problem with it before and i learned most from my bro and i just recently found this site and the understanding that you really can find anything on the internet.
