[QUOTE="keep_hope_alive, post: 7000372, member: 576029"] an HO alt allows you to use the car and play your system while maintaining voltage above 13V (hopefully around 14V). the stock alt only does ~100A of output above 1500RPM, at idle it will be about half. that is true with most alts. when you shop for an alt, look for an output curve. a second battery is sometimes helpful - depends on the system and the usage. A second battery will only help you maintain 12.5V, you need the alt to supply enough current to feed the amp and the entire car (lighting, A/C, engine, etc.) in order to maintain 13.V or greater. your main battery is pretty important - always upgrade that first to a nice AGM that is as large as you can fit. Kinetik makes a good battery. [/QUOTE]
