dds92780 Posted March 6, 2013 Share Posted March 6, 2013 So i bought an 8 inch compact powered sub to be located under the passenger seat. I already know how i am going to run the RCA wires and remote turn on lead. I am having a problem with how i am going to run a power and ground though and make it hidden. My initial thoughts were to use the passenger battery and share the power and ground??? Is there a way to route it into the cab without extra drilling? I hooked my amp for the speakers up to the fuse box constant with an o ring and not sure if i should do the same with this? I also used the cb connections on the side of the dash to run my ground for the amp of my speakers. I figured that all out but how would you guys go about hooking up the subwoofer? Thanks a bunch!

dds92780 Posted March 6, 2013 Author Share Posted March 6, 2013 So i think im just going to look for a spot where it goes through the firewall of the cab and route the power and ground that way. I am going to try hooking it up to the battery directly. Quote Slow and Steady Wins the Race!

Freightrain Posted March 6, 2013 Share Posted March 6, 2013 Those kinda of things, I usually try to wire directly to a battery(including an inline fuse link at the battery end). Even if the unit is fused, I rather not have a glowing red wire if something gets chaffed.Maybe get a terminal post mounted inside the truck, off one of the batteries, for your power supply. Something like this:Help isolate any "add ons" and not rely on the truck wiring to handle the load. Quote Larry 1959 B61 Liv'n Large......................

dds92780 Posted March 6, 2013 Author Share Posted March 6, 2013 I have the wiring kit that comes with everything, i was just trying to think of where to get the wire to go from the passenger battery into the truck. My guess is that if i look in the firewall with the hood open i will find a spot where something can be squeezed in? Will i have to drill a new hole or do you have an idea where the best spot might be? thanks for your quick response. I am going back in the garage to look at it again for now. brb Quote Slow and Steady Wins the Race!

Reuhlz Posted March 6, 2013 Share Posted March 6, 2013 You shouldn't have to "run" a ground wire. It only needs to be connected to the ground (you would assume the cab is grounded.) So you only need a short run to something bolted to the metal, grounded cab. For the power wire an inline fuse is a good idea. You should be able to google "speaker amp wiring kit" and fine everything you might need.
