Amp and switch help.

I am really new to installing amps and speakers, but I was wondering doesw anyone know how to and what rating of a switch to use to install in order to turn the amp on and off from within my passanger compartment. I have a 400 watt 4-channel amp and it is located in the trunk of my 1994 dodge stealth. Also, does 400Watt 4-channel mean I am only getting 100 watts to each speaker if I hook it up to four speakers?

Most headunits have a control that lets you turn off the subwoofer RCAs, if yours don't, get a switch and wire it into t he remote wire. DO NOT wire it to the power wire despite what some people on this forum say, it is NOT safe. Get a switch that can handle 12-14v and a handful of amps.

Ok...I am probably going to sound stupid for asking this...but...which is the remote wire?

the remote wire is the blue wire with a white stripe coming off of the headunit. The amp should have a terminal place marked remote to conect it to.

Thank you, I got that now. And which end should the fuse go at? closest to the amp or stero?

most people don't fuse it, however it would go on the headunit side since the HU is the one supplying the voltage

And about the watts, do I only get 100 watts going to four speakers? Or do I get 400 watts going to four speakers?

typically size is 100 watts per channel, although that may be max and not RMS. That's a pretty good bit of power fo non-sub speakers.
