Just hook up the amp to a constant 12v source in the vehicle. Ignition wire will work perfectly fine...

If it's only going to be for a short-term test then take a small piece of wire and make a jumper from the 12v power input on your amp and jump across to the remote turn-on input.

but keep in mind the amp will be on continuously. so be sure to disconnect it when you're done.

ok i used a quick test meter and that remote screw is a negative...so i shorted it out and blew the fuse

you needed to split the power wire to both the main power terminal and the remote. You also need to ground the amp. If you didnt do all of that, I expect the fuse to blow..

i found the problem..i screwed through a wire when i reinstalled the molding thus it shorted out on the body and caused the fuse to blow...i solved that problem and now everything works great, my HU arrives tommorow

so now i got a new problem i have the amp wired into the lights in the interior right now and it causes them to dim badly....would it stop if i wired it to the battery, its only a 120W amp

You mean you have the amps + wired to the int lights, or the remote wire?

that was possibly the dumbest thing I've ever heard. To CORRECTLY install and amplifier.. you need to wire it to the Battery.

Are you meaning that the 12v power being supplied to your amp is coming from the interior light circuit in the fusebox or something similar?

*sigh*

Run a power cable directly to the '+' of your battery.

If you've done what I posted that I think you did I would expect it to badly dim your interior lights - that's what, like a 10 amp circuit or so? Meaning it is designed to continuously provide less than 10 amperes of current. Powering your amp there = //content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif
