Help - Car Battery Suggestion?

[AdamFink]

Hello!

In the near future, I will be running a full Polk Audio DB Series system powered by two Infinity Reference Series amps (~500 and 700 RMS each) and I would appreciate it if someone pointed me in the right direction when it comes to batteries. My friend currently has 1 of the amps, along with the sub that I am planning on purchasing and there's a large problem. I assume his car battery cannot keep up with his sub because of the fact that it (as in the sub/amp) "turns off" within about 5 minutes of use. With my car having 2 separate amps, I'm guessing that this will even be a larger problem, so I have two options in my opinion.

1. Purchase a battery to specifically power the sub and amp.

2. Purchase a battery to power the entire car, including 2 amps 4 150 watt rms speakers and 2 12" subs.

So what do you think I should do? Please note that I am attempting to keep this cost at around $100.00 hopefully, as my system will allready be setting me back nearly $2,000. Also, if you could tell me of a specific brand or battery to purchse, that would be excellent! If it matters, I live in Cincinnati, OH (I think you buy different types of batteries based on the climate of your area?)

Thanks much in advance!

Kinetik, Stinger, Optima, and others are good brands, but buying a better battery most likely will not solve your problems, you will need a High output Alternator, and to do the Big 3.

I don't think a battery is the problem. If the amp is turning off after 5 min of playing time there is something wrong with the amp or subs.

just get a standard battery. remember the alternator is what powers your equipment with the engine running, not the battery
