Amp grounding point 1800watt amp

So as i am about to install my two sundown sa 12s and 1800 watt amp i am doing a little research on grounding points. I see some people run to a simple seat bolt and that seems to be fine but they seem to be smaller amps. Is a seat bolt sufficient or should i run the ground down to the frame? Any input or advice is appreciated. Thanks in advance

 

run it back to the battery terminal if you are worried about it.

you can always check by measuring the resistance between the negative post and your ground point of choice. too high of resistance can lead to issues or noise.

 

Seatbelt bolt.... Done..... Get past the primer.... Or do a grounding lug. Seatbelt is fine. First off it's on the frame and second, if it's safe enough to hold you it's safe enough for your amp. If it's a clean surface you will have 0 resistance

 

Thanks for the responses. I will test around and will probably end up doing the seat bolt just being sure to sand down to metal. Just got the email that verything has shipped so i should be bumpin by the end of the week.neighbors beware

 

Zero resistance does not exist in 12v world. Your going to be around a 200A draw id say so try to reduce the voltage drop as much as you can.
Personally id just run a ground wire to the battery or to the frame. Simple as that.

 

I get what you say. Simple as that would be frame or seatbelt bolt. This is just a sub amp. Running proper gauge wire for that amp power and ground would not be cheap nor easier than the first options.

 

Cable is cheap for me so its easy to run. I had 4 runs of 2/0 for power and 4 runs for ground in my truck when i was pulling 1,000A

 

Anybody know of a good pre existing frame grounding point under the drivers seat area? Bump for any other advice

 

triple your ground length and run it to the battery mate. Wire really isn't expensive.

 

What does your amp manual recommend? I just installed an Arc Audio amp and the manual stated to keep the ground as short as possible and not to use seat bolts. Many seat bolts use a type of loctite that can be difficult to scrape off properly for a good ground.

 

Yes! I installed my amp this last weekend. This is right under the driver door and there's already a rubber grommet there.

 

hmmmmm
