Orion Amp Ground

[boulderbronco 10+ year member]

I have an Orion 900.2 that I will be using for my 12" subs. I will be running it at 2ohms 450 Watts per sub. I want to give the amp 4 gauge power and ground inputs but the connectors are for 8 gauge. That to me does not seem to be enough wire. Is there any 4-8 gauge reducer for such an application. I will be running a total of around 1500 Watts for the whole system so I am running 1 guage main wire to a distibution block. Also can I run a 1 guage ground directly to the battery? I have always gone to the body but I feel like a direct connection to the battery would be better. The body is not as good a ground as the frame would be. I don't want to go through the body to the underside where the weather can get to the connections. Thanks.

well you can use a distro block for the grounds and use 1/0 wire to 8 or whatever you need. if your amp only accepts 8 awg wire then that will be big enough for the amp. and you should keep your ground wire under 3 feet.

Yeah I am running the 1 AWG to a positive/negative fuse block right by the amps. I agree on the 3ft. rule but I just feel like the body is not the best ground. If you are familiar with how the body of a vehicle is mounted to the frame it is not a direct connection. I think I may go through the body and grommet and seal it real good and connect the ground directly to the frame. Sand it and clean it real good with a solid bolt. Then use some liquid tape and cover the connection real good to seal it from the weather.
