[QUOTE="loopkiller, post: 5489906, member: 601690"] Look this is really a simple thing to discuss here. Capacitors are important in the car audio industry. They are a necessary component inside your amplifier. They do have a function on a much smaller scale than you might guess. They do help provide more stable power, but you are talking about much smaller fluctuations than tenths of volts. Here is one good example of why a cap is not going to help in a modern subwoofer based system. Look at the specs on the RFC10HB 10F cap from Rockford Fosgate [URL="http://www.rockfordfosgate.com/scripts/rightnow.cfg/php.exe/enduser/fattach_get.php?p_sid=JON4IWnj&p_tbl=9&p_id=822&p_created=1167406958"]MANUAL LINK[/URL]. See page 8 where it says "Constant Current Discharge (5A) 15.0v–>3.0v". That means that this thing is only able to give you 5A of constant current. Now I am not some type of genius by any means, but the last time I looked, any sub amp is going to be pulling much more than 5A.
