Switch 12v in rear?

[bste3]

Hey guys,

I have a sub/amp installed in the trunk space. I hooked up the line-switch (forget what it's technically called) to the switched 12v outlet in the trunk. Well then a few months later I installed the bypass to get constant power to my 12v outlets and lo and behold my car battery starts dying on me some mornings. Dummy me takes DAYS to realize why, haha.

Anyway, I either need to undo my constant power or find a new switched source to control my amp.

Does anyone know where another switched line would be IN THE TRUNK AREA so that I can re-wire my amp?

I've been getting by over the last few weeks with a manual shutoff, but that is a pain.

Thanks,
Dan

BUMP!

Plus one more question. If you buy a 400w inverter you really won't even be able to utilize the full capabilities while plugged into the cig lighter because it is only 150w, right? Just wondering so that I don't buy an awesome one with features I can't use. Thanks!
