What battery for extened stereo play?
 

I have looked all over and keep finding different answers.
I'm looking to replace the battery that I use for stereo only and can't decide on a deep cycle or a large starting battery. I have 3 subs and 6 mids that are powered by 2k watts worth of amps. I'm looking to get 4-6 hours of radio play out of this setup.

I have plenty of room and have also considered running 2 large starting batteries in parallel to extend the play time. Anyone have a similar setup that can give me some advice I would appreciate it.



Current setup
Battery selector switch
Battery 1-Stereo- Red top optima
Battery 2-Strating battery

I have the same amount of speakers running on 1400 watts. I run it off of 2 group 31 starting batteries, have played it all day without any problems. I still have 1 battery for each engine isolated via charging relay. Been told that running deep cycle batteries will burn out standard alternators pretty fast.

Add a Kinetic Battery. Depending on how hard your drive the amps will depend on how much battery life before recharge. But the Kenetic will slow the process substantially. I run a Kenetic ( the Kenetic as the main stereo system battery ) and 3 other deep cycle batteries and I run well over 5000 watts thru 4 sets of Kicker components and 4- 10" subs. All alpine & Kicker stuff. 3 amps running it all. No problems...... All zero & 4 guage cabling for power and 14/2 & 12/2 for speaker wiring.

I am using a Interstate "deep cycle" battery, just your typical ugly battery. Mine lasts a 3-4 day weekend. It is a stand alone for stereo only, not connected to the charging system. Typically deep cycle batteries require 1hr of charging for every 1hr of play time, with a charger designed for deep cycle batts. Mine is on it's third season....going strong.

+1 on the Odyssey batteries. No other battery comes close IMHO. Interstate falls on the other end of that spectrum in my experience.

Really? I've had GREAT luck with Interstate batteries. That's the only battery that we could get three seasons out of that we've tried so far. I've never used Odssey, what is their cost in relation to an Interstate?

It's tough to get batteries to last through a MI cold winter, after not using it for 6 months. I guess I could pull them in the winter time, but it is a huge PITA, especially with the electronic hatch actuator.

Kinetic. Just installed mine this weekend.

My stereo: (2) JL Audio subs, (4) MB Quartz 6.5 inch marine speakers and (4) JBL 6x9 speakers. (1) 500 watt amp and (1) 750 watt amp...(1) 4 farad capacitor.

Batteries: (2) Die Hard Platinum deep cycle batteries and (1) Blue Top Optima which is my primary stereo battery. Ive wired one of the platinums in parallell with the blue top. I set my batteries to ALL.

Ive been using this setup for the last 2 years and can run the stereo LOUD for hours and hours. Ive never had any issues with dead batteries and have outstanding sound.

Kinetic or stinger
