How do you install amp and subwoofers in car?

Answer 1

To install a amp, You will need to purchess a wiring kit. You will see three screws on the amp, One that says, pos another that says neg/gnd and another that says rem. The one taht says pos is positive. That is where you put the red wire. The red wire connectes to your battery, before connecting it though, the wiring kit should have came with a fuse setup. The fuse has to get connected to the red wire that comes with the kit. Typically you have to cut the red wire (the one that came with the kit, not the one connected to the battery) and put the fuse system in there put the fuse about 6 inches from the battery. After doing that, don't hook up that wire yet. The neg/gnd means negative or ground. The kit also came with a black wire. You want to hook that up anywhere on your car that is metal to ground out the amp. Hook that up first. You don't have to drag the wire up to your battery like you do your red one. Anywhere in your trunk that is metal is fine. And now the rem. Rem stands for remote. That hooks into your aftermarket stereo. Typically a blue wire but it will say on it. And then you get a long audio cable. White and red that also plugs into the back of your radio. That hooks into your amp as well.

On the amp you will see..... + R - And + L -. Which is your right and left sub. If you are only using one sub you will have to bridge the speaker simply by putting your positive wire coming from the sub on the R + and the negative wire coming from the sub on your L - and that's pretty much it. Hope this helps.
