I have a 2009 SG and would like to put a switch on my aftermarket amplifier, what is the voltage limit on the accessory switch?

 

the switch controls a relay under the seat. the relay is on the p&a circuit so what ever amp fuse is in that slot is what it is. HOWEVER amps run best using heavy gauge wire right off the battery(with an inline fuse as close to the battery as possible) and the ground straight from the battery as well, this is different from cars were u would use shortest run to ground.

 

...and i would probably put a relay on that and get the trigger signal from the headunit.

the acc plug is best used for the type of thing you might want to be able to turn on and off with the switch.

the acc plug has a ground, the acc +, run circuit+ and brake light+...I have posted the pin out before on the forums..you can search for that or look at a wiring diagram in the manual if you want to use that plug...but the amp wouldn't be a good choice.

You could use the switch as the remote lead for the amp. Power and ground would still be run direct off the battery, but the turn-on lead for the amp, if you're not using a speaker-level input that senses signal, could come from the aux switched circuit. I actually did something similar for my secondary amp. I put another aux switch in my dash and have it function to kill the power to the second amp that powers my tourpak when I have that removed.

 

I am planning to put an inline switch on the amp. The bike sits a long time between rides and the small draw from the amp just kills my battery.

 

You should be able to put the switch on the turn-on/REM lead of the amp. It's just a relay circuit, so with no voltage on the wire, there should be zero draw on the +12v power lead. Disconnecting the turn-on wire, do you measure any current draw on the power wire? Or as I mentioned, are you using speaker-level inputs (as opposed to RCA's) that the amp uses to figure out when to turn on?

 

Simply use a battery tender when not riding. You may find your bike already has a suitable pigtail fitted, which many dealers install.
