Hi guys, i can't seem to find a suitable ground for my amplifier (4guage) in the trunk/wheel well. Does anyone have any recommendations. I tried some of the bolts there and scraped the paint yet the connectivity is still pretty bad. Any advice would help. I searched and i don't get relavent posts.

 

there should already be a ground back there if im not mistaken, but i just used one of the pre existing holes with threads and used a screw after i sanded down to the bare metal and it worked just fine

 

yea right where the carpet meets the back of the trunk area behind the seats...lift the carpet up and there should be a bolt there a 10mm i believe...thats where im grounded 4awg as well

 

hey guys, another thing. so i'm using my Rockford Fosgate p5002 2 channel amplifier, except i'm only using one of the channels to power my single 10 inch woofer, at 2 ohms 250watts rms. I have a 4ohm DVC infinity subwoofer, which i wired properly for 2ohms at 1 channel. Only problem is, that when the gain is at under 50%, i get no pounding at all. I have to turn the gain past 50% to make it loud, which is what i don't understand. the frequency is set to 70-80 hertz, and the head unit has the subwoofer signal on full. any ideas?

 

for every intsall i do, i make the ground cable as sort as possible, to a solid part of the floor, scrape away the paint and secure it as secure as possible.

what kind of HU are you running?

 

i used the bolt that goes through the child seat hook. have had no problems with it =)

 

This is where i grounded mine.

 

I grounded mine to the baby seat latch.. sanded it down and put the ring terminal in the baby seat bolt .. works great
