no one was talking about crossovers at all and no the kind of CAP we were talking about, cuts off the bass to the highs cause it filters out the frequentcy of the bass and lets only the highs go through. There are 2kinds of caps. One is used for the lights and keeping consistent power to the amps which is 12 volts constint and the other is used for cuttin out the bass. a POWER CAP is hella big and SMALL CAP looks more like a resister, If you have ever seen one.
