One of the keys to building a great sound system is choosing the right amplifier.

KEY PRODUCTS:
KTP-445 Head Unit Power Pack
Consumers can add higher output and more dynamic response with this easy-to-install head unit power upgrade that fits behind the head unit in the dash of most vehicles. The KTP-445 amplifies the head unit power output, resulting in a 150 percent power increase over the original power from the head unit’s built-in amplifier. The KTP-445 uses an advanced digital design that provides an extremely clean power output with very high efficiency, making the bass tighter and highs clearer.
The KTP-445’s plug-and-play application connects to any 2005 and newer Alpine head unit that has a black power harness. It does not require additional wiring or special tuning. A high/low gain switch allows for proper gain settings, whether or not a subwoofer is part of the system.
PDX Digital Amplifiers 
The PDX digital amplifiers are the best-selling high-end line in the U.S. They are known for their efficient digital architecture, sound quality and reliable performance. Utilizing a small footprint and stackable form factor, the PDX lineup is the go-to amplifier for custom systems.
V-Power Series Amplifiers 
Alpine’s V-Power amplifiers deliver high watt-per-dollar value. As the No. 1-selling family of amplifiers in the U.S., V-Power amplifiers are popular and flexible choices for system building.
