Right now i am running my speakers off my HU. If i ran them off an amp would they sound much better? If i was to hook up another amp just to my speakers how would i go about doing that? is there a way to do that without buying another wiring kit and having to buy another alternator and battery?
If your speakers can handle more power, than yes, you will get better sound with an amp for them. You won't need to buy another amp kit most likely. But this depends on a lot of things. Tell us more about your setup. i.e. how much power you're taking from your stock alt. presently, the size of fuses and power wire you're using for your other audio stuff, etc. Also, what kind of car is this being installed in?
