install is easier than picking and pairing out subs with an amp believe it or not. ha
you get a custom box made for your setup
depending on if you already have a aftermarket head unit. remove the radio install rca cables to the rca line out behind your headunit. run them under your dash and remove the kick panels along your side of the car interior. run the rcas there into the area your amp will be. mose cars have a opening for wires to go through the firewall already so find that it will push right through to your dash underneatth . run the power wire in the kick panels as well.
if you dont have heavy duty wire crimpers. use a vice to secure the connectors onto the power and ground wires. do 1/2 of the connector at a time and then crimp the whole thing to get a snug fit. OR you can solder the connectors to the wire itself for a fast and sturdy connection. you will need to run a remote wire from the remote wire from your headunit as well to the amp itself.
next just run the 10 gauge speaker wire from box to amps. make sure when you ground your amp you remopve ALL paint at the ground location wire wheel on a dremel works great. even sandpaper. and also dont ground to other grounds either. and make sure where ever your ground is, is not thin metal.
if you dont have a aftermakret headunit. youll need a wire harness to supply rcas and remote wire.
