Best Ground

Yesterday i got a protection light on my amp.. this amp has been in for about a month and this was the first time i got a protection anything.... i'm thinking i might now have the best ground i could have... so can anyone tell me what the best ground location would be? i have my amp behind my seat and as of now it is grounded to the seat track... any help would be appreciated!

The seat track is not a good ground. Either run a properly sized cable to the battery, or a properly sized cable to the frame.

Depending on what side the amp is mounted on, you can probably find a grommet under the carpet. If it were on the drivers side, I would run a line right to the battery, poking a hole through the parking brake cable rubber grommet in the firewall and putting the cable through that to gain access to the engine bay and continue the cable to the battery.

Where did you run the positive cable from?

my power cable is running through the hood release grommet... I'm gunna do what my buddy did with his system and get a self-tapping screw and screw the connector directly to the metal of the cab... probably back behind the jump seat.

if you pull up the trim on the floor by the door, in the back there are some like 'pins' on it?

i broke one of those off, sanded down where it used to go and grounded it there

The self tapping screw to the cab works pretty good. Going to the battery is the best bet though.

ran the new ground... volt tested, good volts... just for kicks i tested where i had it.. which was on the seat track.. and i got a good volt reading from that too.. anyway its grounded to the cab floor. the protection light i was getting on my amp was from a blown coil in my sub, which i got a whole new replacement sub from where i bought it and all i had to pay was shipping so that he could ship the old one back... i ended up getting a better sub out of it... so now I'm bumpin again and thinking of ideas on how i want to mount my amp because as of now its just on the floor and i think the carpet is making it get hotter than it should... anyway thanks for your guys help.

put it on a board with 3 inches of space between it and seats or floor etc. 3 inches of air will be fine for your amp and shouldnt let it get too hot.

Finding the shortest possible ground cable length is the best bet.

My amp is grounded to a bolt that held down the driverside jump seat. The metal around the area was sanded down to bare metal for the best connection possible.

on the driver side of my truck, behind the jump seat. theres a rounded off rectangular hole at the bottom. i think im gunna run a positive and negative throught it, so i don't have it rammed througth the fire wall. check yours to see if theres a hole there too. that will save alot of work if you chose that route.
