I'm in need for a grounding kit, what's the best you guys have used? Any recommendations? I don't want to spend 300 or more for some wires. Please help.

 

There is a thread somewhere that tells you the 3 or 4 locations necessary to properly ground your car. Personally i followed that thread, went and bought some speaker amp wires and have been extremely happy with the results.

 

Try fixing the stock ones first and see if that'll fix your problem. What is the problem exactly?

 

All grounding kits are nothing but a scam.

Yep, they are total crap. Fixing whats already there is all you should need to do.
