You need to hook power upto the + terminal of the cap. You can either cut the power wire going to the amp and put ring terminals on both ends of the power wire and hook it to the cap or you can run a power lead from the amplifier directly to the cap. For ground you would just use the same gauge wire as the power from the ground terminal of the cap to chassis ground.

Either method is fine, so long as the proper guage of cabling is used for ground termination.

it doesnt matter which method you use as long as the impedence on the ground is equal to almost none.

We questioned the why you should ground the capacitor in our bay for quite a while. we came up with this answer

you should ground the capacitor and the amp seperate to the same grounding point, the reason for this is we all know the the amp should have equal gauge power and ground, when you hook up a capacitor as the system demands power the capacitor shoots its stored charge into the power wire which is needed for the increase in current draw as this happens it also causes an increase in ground current which is why the seperate ground is needed it also helps the capacitor run more efficiently

PS. you should always upgrade the ground wire on your battery to the chassis of the car using the same gauge wire as the power wire, otherwise your return ground path goes through that little 8 gauge wire which is also shared with all of your vehicles OEM electronics. it is by far the best electrical upgrade you can make on any system

hope this helps all who are curious

your happy installer
