[QUOTE="winkychevelle, post: 8614910, member: 611804"] To power that mojo you should look for an amp that can reliably make 2500-3000w at 1ohm. Can the sub take more power? Yes it can but with your current experience level I fear you would only be reconing the sub a lot faster than you want. As far as room for an upgrade? Well you would need to specify the upgrade. Can a 2500w amp power 2 2500w subs? Sure it can it will simply split the power to 1250w each, but then you are not reaching the full potential of the subs. Is that a bad thing? Well it depends, if you want to move more air or hit lower notes, more cone area will do it. But if you want much louder you need more power with more cone area. 3000w is a lot of power for an average user. A typical 3000w amp can draw anywhere from 320-375amps of current from you batteries and alternator. This is why it was stated above to go with the biggest alt you could afford. Batteries can offset the lower alt ratings but you lose power allowing the voltage to drop from 14.4v to 12v. Not only that, the batteries can only supply 12v for so long before the alt had to recharge them. If your amp is drawing 300 amps and you have a 300amp alt you car will still draw 20-50amp for its functions which will inevitably pull the voltage down and drain the batts. But there is a silver lining. If you are listening to music, the amperage draw of the amplifier will not be consistent and it may only draw 300amps for a few seconds and allow the alt to charge the batts back up in between bass notes. My recommendation: A 220-250amp alt or bigger if possible. A good Agm battery under the hood (the largest that will safely fit) A group 31 battery located as near to the amp as possible. You may need to add more batts as needed to stop voltage drop. Do the big 3 upgrade in 1/0 ofc wire Run 1/0 ofc for the amp and rear battery. Ensure a good ground if using the body/frame as the grounding point. Set the gains properly (this is the most important part) I would also be curious as to what kind of box you are using because prefab **** for the most part and custom is the way to go, save a few good prefab makers.
