Doing My Sound System Today Need Help
I have a 36v ez go golf cart. I plan on running 4 boston acoustic sr65, and one Kicker L7 8 inch woofer. I am leaning towards pushing all of it off an Alpine PDX 5 channel amp due to its compact size. The amp has 2 30 amp fuses. So im guessing 60 amps max pull at full tilt. all running off a pioneer headunit (single din).
My question is should i go with a voltage reducer, extra 12v battery, or what? Im going to buy what I need today so all suggestions are welcome! I've also heard of running 2 wheelchair batteries but i'm not sure. Want the option that will feed my amp the best power and give me the longest playing time possible (although, I know this wont be TOO long) Please help! |

Re: Doing My Sound System Today Need Help
Whats the budget? pulling that kind of power of a set of batteries doesn't seem like a good idea. A reducer or 12v batt are the 2 most common methods i have read on here. Personally I added a 12v batt to run all my 12v stuff and ran some copper studs through the kicker pannel to hook u pa charger to it when needed. If the money is no issue, a solar panel on the deck will continuously recharge the battery and will improve your playtime; by how much I am not sure.

Re: Doing My Sound System Today Need Help
I parallel two 12 volt 18 amp/hr. computer ups batteries. They are compact and provide plenty of power. I run a sony receiver,two sony 3 way 5.25 in the front, two kicker 6.5 component speakers be hind the seat and a kicker
8" sub and a 400 watt 2 channel amp. I built a custom box for the kickers behind the seat and mounted the amp under the back seat. The sub is in a box in the bag well. Good luck to you. The batteries are on the drivers side in the battery compartment. |

Re: Doing My Sound System Today Need Help
also, how would running 2 of those small batteries mentioned compare to running one big 12v battery (i was suggested an optima blue top)
should I just refer to the Amp hour rating to tell what kind of power and playing time they will have? or does that always matter? |

Re: Doing My Sound System Today Need Help
I charge them with a regular 12 volt charger. The batteries are alot smaller and weigh alot less than the optima battery. When paralleled you get 12 volts and 18 amp/hr. for an extended time. I built a beach radio last summer out of sound system on golf cart and ran the same two batteries. It lasted about 5 or 6 hrs.

The batteries I use are EverOn EVA12-18NB 12v 18Ah AGM Sealed Non-Spillable Battery. Google the batteries and you can get the demensions. I think the batteries are used as a back up power supply on alarm systems also. Good luck to you. Also post some pics. of your install. Pictures are great.

Re: Doing My Sound System Today Need Help
I vote for one DEEP CYCLE Marine battery, it will do everything you need to do for under 100 bucks and fits nicely under your seat. Check Harbor Freight for a cheap solar charger.
I think Optima's are over priced and a little over rated. I run your standard Academy Sports/West Marine batteries in my boat and have never had any problems, my buddy runs 4 Optima's and is always having trouble with at least one of them. |
