I have an 89 accord lx (carbed) and I was wondering if I will need a new alternator for my sound system. It consists of: JVC G800 deck, infinity ref. 5 1/4 Front, Infinity ref 6 1/2 Rear, Phoenix Gold Octane 80.4 for the speaks and Phoenix Gold Octane 15.1 for the Phoenix Gold Octane 12'' subs. Total Rms wattage is 1320 peak is 2300. I have a 3 farad power acoustic cap and a dual battery setup(1 stocker 1 stinger)(yes, I realize that dual batteries are just a bigger reservoir to drain) Will this setup require a new alternator? Where can I get a strong one for cheap?

thanks

 

You will never know for sure until you try it. But, to put it in perspective... I'm guessing that Accord has around an 80 amp alternator stock. Your stock electrical system probably pulls around 65 of those amps (this is being generous). With that kind of wattage, I bet you will pull at least 50 amps when you are listening loudly. My guess is you will need another one.
