Generally you connect it to the red wire on the HU not sure if it always red?, so just splice it and make sure you get a good connection and tape it up really well.

Yeah that ohm load will work, you can always go higher, just not lower. You just wont see the amps full power potential.

if he has an aftermarket radio, the remote turn-on is the blue/white wire.

if you want a good connection - tape doesn't help. solder and heat shrink is the way to go. a quality crimp connection and heat shrink at a minimum.

Did you get the GMOS adapter for Class II Data Bus retention?

I need help finding the wire in the car to tie into the remote wire what channel amp is better

are there two questions in that post? can you separate them with question marks for clarity? thanks.

the remote wire at the head unit connects to the amp turn-on. the color of that wire depends on what you run to the aftermarket amp - you need to install a wire to turn on the amp and give it power and ground. if you are trying to turn on a factory amp, then you need to look up the factory wire color codes for your specific year/make/model vehicle.

what are the makes/model of every piece of audio equipment you have and want to install? what is installed currently?

im talking about the aftermarket head unit it has a 12v continuous power wire, a ground, and a ignition wire. i need help finding where to tie in the ignition wire. im sorry i was calling it remote it has been a while since i have connected a system. the other question i have is what channel amp will i need to run in order to get the best sound and loudest?

the equipment is 3 dvc 4ohm memphis subs and a 1 channel 1ohm stable 1000 watt amp

youll have to tap the ignition wire, its brown and comes from the harness coming out of the steering column. it goes to a patch panel in your center console on the drivers side, there is a plastic panel with a heater vent that pops off where you can see it. youll have to probe it or wait a while so i can take pictures. just poke it wit a dmm and find which has acc power. i would then go get a relay and use that for the signal. if you just splice the wire for acc youll blow something. power is down there too but you can pull off the factory harness (safer.

if you run two of those subs you can have 1ohm
