i plan on getting a new alternator. Or would a capacitor work?
if i have 2 15 kicker L7s and a hifonics BXi 2006D amp how many amps should my alternator be ?

buy another amp or two because that hifonics is crap and messing up your subs slowly but surely from under powering them, you can add a cap until you buy another alternator but you do need one, also you should be running 0 gauge all around, you replace that trash amp with a kicker and it will beat twice as hard

good luck
If your total system power is 1000 watts RMS or more, you will need to:
1. Upgrade the alternator to a high output alternator
2. Upgrade to a heavy duty deep cycle battery
3. Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 1/0 AWG wire.
Failure to do this will result in you replacing them anyway as the alternator will eventually fail.
Here is a guide that will calculate what size alternator and power wires you need http://www.datafilehost.com/download.php?file=6d26...
You will need Microsoft Excel, an AC voltmeter and a way to burn an MP3 to CD to set the gain right. Email me if you don't have Excel.
A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.
A cap is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing esle. If the current isn't there, a cap won't help. The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.

What Sparky said, but considering your going to buy a Hiphonics amp, you won't be getting the full 750 RMS per sub since it's most likely an overrated amp.
most stock alternators are about 80 amps and for something that much you need atleast 180 amp alternator
