2 Subbbers

2 Subbbers
I have a 12" sub, and I am able to get a second 12" for a great price. When should I look into getting a second battery to power them, or is the one battery enough for it to run well without cut outs? Any advice is appreciated!!

Until you can awnser most if not all of those questions, you won't get a response that will help you.
That being said, with the info that you've given, i'm sure that the awnser to your question is no.

Even without knowing that above information, I will say "No, you don't need a second battery yet."
Of greater importance is your electrical wiring:
From Battery - to the Chassis
From Alternator + to Battery +
From Alternator - to Chassis.
Upgrade those wires to 4, 2, or 0 awg first.
If you only have 2 12's, I really doubt you will need another battery unless each sub is getting a kilowatt each.

I think a better question for you to ask is:
"Can your amp handle a second sub?"
Stereo amps typically are 2 ohm stable stereo, 4 ohm stable bridged
Mono amps can range anywhere from 2 ohm stable to 1/4 ohm.
So what is the impedance of your sub(s)? Are the single or dual Voice coil?
Improper matching can cause excessive heat, amp failure, or even a BBQ in your car. Check all your specs before throwing an additional sub into your system.
Also, will the 12s be the same make? . . . please don't get mis-matched subs - too ghetto ugly, and they will perform very differently giving you sloppy sound . . . yada, yada yada.

I don't have very much knowledge when it comes to Car Audio, so I will tell you what I can for now. The Sub which I am looking to buy has it's own amp so I would have 2 subs and 2 amps, but they are different makes. I will probably be using a 0g wire to prevent future replacement if I decide to add add more later. I have so little knowledge that I probably will be getting them istalled, I just wanted to ask here so they don't try to rip me off. Or even if you think I should just stick with what I have. Here are links to the stuff i've got hopefully this will help!!

He's says he has a second amp for the new sub. It won't push the sub for all it's worth but it should still work.
Baam, if your getting a shop to install your system, make sure they realize those amps are fairly underpowered for the subs, and let them know you don't want your settings set very aggressive. Most important is the amp gain, as that is a high output deck. Setting the gain too low, like <1 volt, will blow those subs in a hurry.
If you look to upgrading later, look for an amp that is ~1000-1200 watts RMS at either 1 or 4 ohms. I think someone on the board here has a 1500 watt @ 1 ohm amp. It's a bit much, but at least you'll have a nice clean signal, making the bass sound much better.
Good luck

So from what everyone is saying, I gather that I got ripped of and sold a wimpy amp which is powerful enought for my sub. What wattage of amp should I have for that sub to run at 100%, if I have a 12" I don't want it to sound like a 6". Damn you Best Buy!! It's all still in the boxes except for the deck, so maybe they take em' back. haha ya right. Also is putting in the 0g to start off a good idea, this way I won't need to upgauge it ever. Thanks again.
