grp 31

are these type of batteries ok or up to par as far as running it as a dedicated battery in the rear trunk for a Kicker 2500.1D amp? I have the big 3 done and I have 0 ga. wires through out the system.

I have two Odyssey PC 2150's....never got used though...was originally gonna feed an RF t30001bd and T8004, but then changed to 4 PDX 1.1000's and a 4.150. Oh, and I'd use this in the trunk, don't know how they would be for up front and it would be hard to fit under the hood, unless you have an SUV or make some mods under the hood.

Why do you need a 2nd battery dedicated just to a kicker 2500? with the big 3, 0 guage wiring,and "maybe" an upgrated front battery....i wouldn't think you'd even need a 2nd battery. //content.invisioncic.com/y282845/emoticons/imo.gif.3a57bcc70a4835dc53e86ffae1a0b041.gif

you'd be surprised at the volt drops i had before the 2nd battery. insane.

YT= yellow top correct? I can get some grp 31 from Interstate Batteries Company for like 41.00...I think they are refurbished is this still a good deal?

becuase Kicker recommends it for one and btw my upfront battery is a Sears Die Hard which are very good car batteries.

are the sealed, or lead acid?

sealed

then i'd say thats a good deal. IMO lead acid = no go inside the car (trunk)

thats good to know and I know with the added battery will I need to add a battery isolator?

THIS is very true.........but i've had-used several kicker amps and never ran a 2nd battery. each his own though and if you get a signifigant voltage drop then a 2nd one is in order i guess. kicker has never told me i needed another battery before though, not even when i was running a bd1000 and kicker 650.4 did i use another battery, a 75 farad cap did enough for voltage. not trying to argue or anything. i'd get a kinetik only because they have a very small footprint and are reasonably priced.

I think you have to have the isolator to keep the 2nd battery charged.

do you have plans to have the car off, system on and up for an extended period of time?

if no, then no isolator is needed.
