- Once you have decided on the battery placement, keep the battery on that place.
- Use a battery box. Go for the drilling option to make some holes on the installing tabs on your straight on the floor trunk. Use bolt on the holes (you just created a while ago) and adequately tighten all of the bolts using a wrench. You can get all the hardware from the battery box.
- Once you have done the setting process, you have to wire your second or auxiliary battery correctly. However, firstly connect the positive side.
- To wiring, the second battery, use some copper wire with a heavy gauge. Use a Wire Stripper; remove some plastic cover from the copper wire to make a terminal end on both sides of the copper wire.
- Add one side of this positive terminal (copper wire) to the Positive Terminal of the battery and the other terminal to the Amplifier’s Lug.
- Finally, tight the screws as firmly as possible. Uses a wrench to accomplish this tighten procedure.
- Find the ground wire from your auxiliary battery’s negative side. Once you have connected properly, both the negative and positive terminal closes your car’s trunk/hood. Make sure you have connected both the negative terminal on the ground and the positive terminal together. (Using an In-line fuse/Battery Isolator for this connections)
