Answer 1

you non't need one but it would have less drain on your alternator after dark start the car up crank the stereo up with the headlights on if they dim i would put one on but you don't have to

Answer 2

Answer 4

NO, they are a waste of cash-

if your lights dim at night when the sounds are on past halfway and you also have another accessory running (rear defrost and/or AC) then you need to upgrade your charging system

you want to upgrade all of the wires in the charging system to thicker ones, and upgrade the alternator to a high output model, and you could then add a high current car audio power cell (kenetik makes the best ones in my opinion http://www.sonicelectronix.com/cat_i228_... if you don't upgrade the charging system you will just put more strain on your factory alternator and make the problem worse

Answer 5

that depends on what kind of car you're running it in. Generally speaking, you shouldn't need one if it's in at least a mid-sized sedan.  Just make sure the alternator is putting out at least 70 amperes of power.  Is it a Kicker CVR 12"? Because if so, great choice on the sub, it pounds!
