The new V-Power products are now Class D digital amplifiers, resulting in a huge efficiency gain versus their predecessors without draining your battery or your pockets. Class-D provides continuous clean power to your speakers, operating at 80% efficiency far greater than conventional Class A or B amplifiers. Translation: Enjoy cleaner bass, even during extreme power demands..
V-Power amplifiers are known for their compact size, but don’t underestimate their power capacity. Although they have a 40% smaller footprint than their predecessors, they produce the same amount of power as before. Get the power you need, even if you have limited installation space..
Parabolic Cone Structure with Pulp/Kevlar Cone & PP/Mica/Talc Dust Cap..
High Amplitude Multi-Roll surrounds (HAMR).
This package also includes a 4-gauge wiring kit with full copper wiring and 2-channel RCAs..

As a VU meter, with dual 60*35mm large meter, can dynamically decorate audio environment and provide incomparably visual effects when switching audio signals..
As an audio switcher, easily to switch between two amplifiers and 2 pair of speakers, no need to plug in and out cables repeatedly to avoid wearing the contact point of the sockets..
Powerful design and strong compatibility: all channels adopt fully isolation design, each channel’s GND is independent without mutual interference. Supports all kinds of amplifier such as BTL / class A / class B / class D digital amplifier / tube amplifier etc..
Easy Use & Perfect Details: Powered by micro-USB 5V, with built-in protection load for speakers. With remote control, can quickly set the working status from distance. All settings can be saved after shutdown, more convenient to use..
Proper size with exquisite appearance: cool black case, warm VU meter and clear indicators looks vintage and dynamic, can perfectly match with a variety of usage scenarios, very suitable for audiophiles who have more than one amplifiers or speakers..
