just installed Tuned Innovations Groundwire Kit... i gotta say i didn expect much from this but i was like what the heck its only 30 bucks.
so i got home from work and went at it. install was easy but long
anywayz i noticed improvement with the first crank i gave my baby.. damn i was like my car sounds louder
i let it adjust came back later and i turned the stereo on.. all i gotta say is WOW, sounds deeper i can hear beats i never heard before and i turned on my subs and again i was happy
car runs smoother and i feel a difference when i rev my car especially on the low end. took it for a spin and not to much difference but theres that little change and thats good enough being that this mod was cheap
this groundin kit is like the s2k antenna, one of the first mods you gotta get! well just in my part this is mos def worth the buy
