    I'd like to kill all power to my amps and inverter when the car is off because it sits for a week at a time (without having to go under the hood with a battery switch).

    Does anyone know where I can get a high amp switch that is freestanding and not a relay but direct (so it's cheap and reliable).

    Switch "only" needs to handle 25amps max, I have small amplifiers.

    Not sure what to search for, cannot find anything suitable (that's cheap).

    ^ that will do it. however i don't see what the point is. i have had my car sit for longer then a week and never had power drain issues. that is with an alarm on also.

    I don't understand why you need it either but Radio Shack would have what you want.

    I wanted it because the voltage is always 11.9-12 volts in my car after a week of sitting and I suspect it's my old amps causing a light drain. Should be closer to 13.1 right?

    This is even with a brand new battery.

    So this would be a cheap solution.

    the last car i have a voltage meter in i would se low 12's after just sitting over night. driving around it would be in the low 13's. so in the 11's after a week isn't bad.

    You could probably pick up a high amp switch at any auto parts and maybe even in the automotive section of Walmart.

    12.4 is usually what they run at when engine is off. no need for fancy switches and junk.

    It is very bad for a lead-acid battery to sit at lower than optimal voltage for even just several hours, the plates start to sulfate.

    oh yeah i forgot to take into account not everyone has a gel cel battery. then yes your battery is going to be effected. however.....if its such a big deal why not just disconnect the battery ground?
