I will be installing a new Infinity Basslink in a week or so and I was wondering if it is safe to power the sub off of the underhood relay box or should I stick with the battery? Is there any difference in power at these 2 points?

Any help would be appreciated!

Thanks in advance!

 

I'd go straight from battery, to fuse block, than to amp, I'd keep it simple and do it the, I guess "normal" way. I think if you ran it off the relay box I don't know if it would get all the power possible. And in your sig for Mods, did you do that mod where you push the window down and it goes and and up goes up? Or did you do the one that is wired to your keyless remote?

 

The windows auto up and down is controlled by the window switches.

 

You can connect it at the battery or at the two large screw terminals outside the box under the cover. It's the same power. You should put an inline fuse within 2ft of that connection.

 

Damn, okay, but yeah, good luck with the wiring :)

 

Thanks, thats what I needed to hear. The amp kit I got has the fuse already built into the power wire.

Thanks again!

 

I have three circuits off of the positive cable connection on the front of the distribution box. I prefer to connect here away from the corrosion that can be a problem at the positive battery terminal.

At Matt pointed out, there are many amps available here and you need to have the circuits fused close to the studs. The small plastic cover that protects the studs has been removed for the photo but must be replaced when in use.

 

Thanks for the info Bob! I wanted to use this spot because its a little easier then hooking up to the battery and as long as its all good, thats where I will be using for the basslink.

 

It's very handy.. I do the same as well. Although follow the advice here and put your accessory fuses very close to the terminal, like in Bob's picture.
