Im wondering what it would take to run a single soundrive 18 inch subwoofer at 2k rms? I'm wondering things like would I need to upgrade my stock alternator and how many batteries (and what kind). Im kind of unexperienced when it comes to this size of subs so any help would be greatly appreciated! Thanks in advance. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gifSounDrive SDA3 18 Subwoofer - SounDrive Audio Store
