Alpine R2-SB10V Single Type R2 10-in Subwoofer in Vented Enclosure -
The new R2-Series subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control compared to the previous generation. ProLink is unique to Alpine and allows you to link two R2-SB10V enclosures together using an optional KTX-H10 Linking Kit (sold separately) to create a dual subwoofer-enclosure.

Alpine S-A60M Mono Digital Subwoofer Amplifier - 600 Watts x 1 @ 2-Ohms & 330 Watts x 1 @ 4-Ohms -
The S-Series amplifiers were designed to perfectly complement the already established and loved S-Series speaker and subwoofer line that Alpine Electronics has continually improved for years.

The S-Series Amplifiers have a diagnostic LED located behind the blue Alpine Jewell on the top of the amplifier. A Blue light means the amplifier is operating normally. A red blinking light means the amplifier is currently too hot for operation and needs to cool down. A solid red light can mean three things; 1. Amplifier circuit is abnormal. 2. Temperature is too high. 3. Power supply voltage is too high.
