At KnuKonceptz, we do not use “watts” to rate our amp kits. This is a very inaccurate method to determine what the proper gauge wire required for your amp installation. There are many amp manufactures and not all of them represent the output of their product accurately. Please refer to your amplifier’s fuse rating, this is a number a manufacture can not fake, well they could but it would put their product in harms way! Add up the fuses on the end of both of your amp (ex Amp A has three 40A fuses = 120A draw; Amp B has two 30A fuse = 60A Draw; 180A system total draw) If this number is under 300A, this kit will fit your application.

Using the information from the answer above, the example system draw totals 180A therefore a 200A fuse is the minimum required and the safest option for the inline fuse holder. For your fuse block you would select a 120A and a 60A fuse respectively.

The fuse holder does not come installed within the kit’s cable. This allows the installer to place the inline fuse holder in an optimum location during installation. It also allows the installer to extend the power wire 1-3Ft by using the inline fuse holder to add cable to the main run (leaving the 18Ft as one unit and using the FH-20 to “splice” a few feet of wire)

The 2Ft of 1/0 Gauge black is meant to upgrade the battery to chassis ground. Connect the two black ring terminals to the 1/0 gauge black ground wire. Connect one end to the vehicle chassis and the other end to the battery’s negative terminal. Using the 4 gauge black ground wire, determine placement for the two amplifiers and cut the wire accordingly into two pieces (one cut) so that both amps have a chassis ground cable. This chassis ground should be one common point for both amplifiers to reduce any possibility of a ground loop. Attach the 4 gauge black ring terminals, one to each end of the now two ground wires. Secure the two 4 gauge grounds tightly to a clean location of the vehicle’s chassis. Repeat the same procedure for the 4 gauge power wire, connecting them to the output of the BK-2020 Fuse Block

Your vehicle’s wiring was engineered to work with the factory electrical load. By adding a massive current drawing load requiring a heavy 0 gauge power wire, you also need to upgrade the vehicle’s ground wire. This kit includes the appropriate parts to complete this upgrade. The 5′ section of ground should be cut one time (to make two sections). These do not need to be even length, but rather cut to fit your installation’s need. You may only need 18″ to connect the battery to your vehicles chassis. The remaining 0 gauge ground wire is then used to connect the audio amplifier to your car’s chassis.
