so i was taking the system out of my Sunbird, i noticed that when i hooked up my amp about a year ago (i was a bit more uninformed, etc. than i am now) but it seems i wired the amp with 4ga power wire, but for some reason i grounded it with 8ga wire.. which definately doesnt make sense but for whatever reason that's what i did, lol.

so i went to my first SPL drag over the weekend, scored 135.6dB with 1 12" pioneer and ~800RMS amp. if i had this amp properly grounded i know it would be alot better for the amp probably, also would i have scored any better? either way, first thing i am going to do when i install my gear into my other car is ground it with 4ga wire right off the bat. was just curious if i would notice alot performance wise if it was grounded correctly in the first place?
thanks!

For some reason, most amp install kits include a smaller ground then power. If you really want to maximize you spl, ground directly back to the battery.

It really depends on the amp, I doubt it would have made any large effect on that amp. If you are putting out over 1000 watts you will definately see an improvement.

you don't need to ground directly back to the battery for a 4ga wire, I guarantee that the frame of the the car has less resistence then a 15ft run of 4ga

Rule of thumb is always use the same size wire for ground as power.

yeah i have a 2ohm load on the amp now so it's around 800RMS, once the system goes into my other car tho the 1st thing i am going to do is replace that 8ga... and that's probably why i did it too, the stupid kit came with 8ga ground lol. still tho even last year i shoulda picked up on that.

thanks for the replies guys!
