JL Audio Slash v2 Series 1000/1v2
JL Audio’s Slash v2 amplifiers aren’t just powerful, they’re smart. As your battery voltage fluctuates while you drive, the Regulated, Intelligent Power Supply™ system maintains steady, consistent power at any impedance between 1.5 
and 4 ohms and at any voltage between 11 and 14.4 volts. You’ll get all the power, all the time, even with a wide range of speaker combinations.
The 1000/1v2 mono amplifier puts out 1,000 watts RMS of clean power to your subwoofer system, and JL Audio’s patented Class-D amp circuitry keeps a tight rein on cone movement. The cast aluminum heatsinks dissipate heat quickly, giving these amps long lifespans and reliable operation. You can stack multiple Slash v2 amps, saving you valuable space in your trunk or cargo area.
like you’re using the iPod itself. It’ll even display album art from your iPod. Once they’re connected, the Alpine bypasses your iPod’s built-in digital-to-analog converter, using its premium Burr-Brown DAC to deliver your music files with the highest fidelity possible.
