ARC AUDIO XDi-450.4

Just because its the smallest amplifier in the line doesn't mean it can't pack a big sound. The XDi 450.4 is the baby of the XDi amplifier line while providing a well supporting 85 Watts into 4-channels driving even the best speakers to their sonic limits in your vehicle.

The XDi 450.4 is a compact and elegant design that is small enough to fit just about anywhere in a vehicle allowing you that personalized "Big Sound" without the loss of valuable trunk space. This compact design allows the whole things to fit under practically any seat and when used in combination with the XDi 650.1 or the XDi 1100.1 you now have a package suited for even the most demanding of listeners.

Trimmed with ARC Audio's level 1 XDi series cosmetics the simple but elegantly designed stamped top cover design is accented with a diamond cut aluminum badge and a texture coated finish. Removing the top screws allows users to rotate the badge literally into any direction improving the amplifiers flexibility for installation. If you desire the cosmetics of the Level 2 product, no problem. The XDi 450.4 is upgradable by purchasing the XDI Trim kit and you can have the same cosmetics and display features of the more expensive Level 2 cosmetics.

At this affordable price point the XDi amplifier series is perfect for the daily driver or the wildest of custom installations.
