[QUOTE="old_dude, post: 5719135, member: 608305"] I was in the same dilemna as you were. Wondering if I should get a bigger $300 Bosch H/O alternator. But my friends and even local experts all said I should get a battery in the trunk instead of a bigger alternator. Besides, I found out the Bosch won't even fit in my car! What I was told is most important to look for in a new 2nd battery is Reserve Capacity. Never mind Starting Power ratings. Look for the ones with the best Reserve Capacity, being Deep Cycle Marine of course. My buddy, who owns an alternator shop, also said I should just run a Continuous-Duty Solenoid back there, which would save me from having to run a battery isolator. I got both: the battery (not the highest Reserve Capacity I could find, but for coolness sake I bought the one with the highest price tag!). I found DCM batteries with Reserve Capacity well over 210, but got a Optima, which only has a Reserve Capacity of 120 (lame, for that price!). I also got the solenoid mentioned. My buddy says all I will need is a little 16g or 12/10g wire to run this setup. I suppose I'll find out! I'm still confused on how this setup gets hooked up, which is why my friend has agreed to show me how easy it is. He claims it takes a matter of minutes! I'll let you know how this ends up being connected back in the trunk when it's done. In the mean time, I can tell you where I found my solenoid the cheapest ($15)but you can find them locally at most parts stores. Good luck! [/QUOTE]
