Rainbow Audio CS 260.30 Reference
Rainbow Audio's CS 260.30 Reference Series component set ($6,579) has all the bells and whistles you'd expect from luxury speakers.

Within the closed aluminum housing is a ventilated neodymium ring magnet system. Lastly comes the copper-plated shielded crossover, also with gold-plated terminals.

Alpine PDX-1.1000
Producing more watts of power per cubic inch than any other amp on the market, it's easy to see why the PDX amps have become so popular in space-lacking vehicles. Thanks to a groundbreaking damping factor and intelligent power processing, the monoblock PDX-1.1000 ($850) provides crystal-clear sound and excellent speaker control despite its small size (only 10.5" x 7.5" x 2.5"). Speaker wire plugs into the high-current, low-impedance speaker terminals that provide greater surface area while offering improved longevity and reliability. And thanks to their efficiency, the PDX amps maintain steady, low-temperature performance with no risk of sudden shutdown, even when they're stacked.
