im getting it for other reasons tho. first by running accessories i have burnt out a battery, and my alternator is probly on its way out. secondly i need to use my accessories due to where i live, now the heater and rear defrost are pretty much always on - i need the power for them. thirdly its for a sense of security. it may not need it and will probly be fine for my atx but the way i use my car i need it.
