Where are you grounding your amp (under driver's seat)

Just curious where everyone is grounding their amp if you put it under the driver's seat (IN A DOUBLE CAB)? pics would be nice if you have any as well, thanks!

 

whatever you do, just dont ground it to the seat bolts.

 

Why not?

 

i have a single cab, and i put my amp under the passenger seat, and my 8'' sub right behind the seat, fits perfectly.

 

I'm assuming you grounded it on the back sheet metal?




I should have specified, where is everybody grounding their amp if they have a doublecab? thanks

 

Maybe not apples to apples, but I put my amp behind my rear seats and ground to the middle seat belt bolt. A Bolt is a bolt and it went straight in to the metal body of the truck. I used a wire brush wheel first to clean the entire surface down to shiny metal so the contact is solid. I'd think doing the same under the drivers seat would be sufficient.

 

I just run the ground to the side panel and use a metal brush to the body and then a self tap screw. I use to work in Audio Video and this is how a lot of installers do it. You need the shinny metal to get the best ground.

 

One thing you don't notice is that the seat belt bolts in many cars are not attached directly to the frame. Its just a heavily reinforced area attached to the sheet metal.
There is also the possibilty of noise from a bad ground being transfered through the system

Into the frame.

 

I used one of the rear seat bolts.
Sanded down to shiny metal on all contact points, works well for me and I have no noise.

 

Grounded to the frame.

 

nice, that's hardcore, thanks for the pic


glad to hear it's interference or noise when going to seat bolt, rather than electrocution

 

This is the ONLY correct way to do it. Your grounds must go to the frame. Seat belt grounds, as mentioned already, do not tap into the frame typically and will not suffice as a correct grounding point.

TheeMan is 100% accurate. +1 to you Threeman!

 

any concerns about going offroading/ driving in rain/ rinsing undercarriage and getting it wet, and then driving with it on?

 

I dont think its the only correct way if grounding to bare metal under the seats or other metal mains in the body have worked for so many other people. I wouldnt want to drill a 4g size hole in the bottom of my cab

 

No. Use a grommet then seal it if you think it needs to be more tight.

You can ground to bare metal anywhere you like. Doesn't mean its the best place to ground. I've seen people ground into sheet metal that's not sanded down to bare metal it still worked. Look at it this way, if I put 87 octane in my motorcycle that was built for 91 octane it still works. It runs like shit, but it works.

Having a good ground is one of the most important parts of an audio system and I personally wouldn't cut corners when it comes to main power or ground.

 

Your metaphor is a bit off.
This is more like your motorcycle is built for 87 and 91 or 87 works and they both run the same.

Im not disagreeing that technically the frame is the best spot to ground to, however I do believe that it doesnt make a lick of real world difference to other good spots.

 

not so much water getting in the cab, I mean if the ground terminal were wet, and the system were running, would that cause any potential hazard

 

I used the left front seat bolt to ground mine, works great for many months now with no interference through the speakers. I'm happy.

 

I dont see how it would, thats the whole point of the ground.
