im kinda new to amps and subs and all that, and im lookin to put a pretty kick a system in my car and wanted to know bout the ohms on amps and the ( 500 x 2) on the subs and stuff. what would be a good way to go with amp and subs?
Welcome to the forum.
For the most part, car audio is 4 ohms. Many car subwoofer mfg's list driver handling in peak power. You want to look for rms power, or continuous power handling - not peak power.
When you wire multiple subs in parallel (as you should), your resistance drops (ohm rating). It will also dip down even lower if you run multiple subs that have dual voice coils (higher end car subs usually have these). IE, if you run two, dual voice coil subs in parallel, rated at 4 ohms, your amplifier will see a 1 ohm load. Only the best amps are 1 ohm stable. Basically, you need to match your driver choices to a capable amp.
What is your budget, and will you be building your own box? The type of box dictates how much power you'll need. A sealed enclosure requires a larger amp for the same spl's as a ported box. You can get a lot of bass from a smaller, sealed enclosure with proper damping, but you'll need a large amp to power the drivers.
