BLUETOOTH “AMP-IN-A-BOX”

Do you want high quality sound for your bike but don’t have room for a separate amplifier? This was a problem for our customers as well, so we started building these based off a classic Harley tool box.

Inside is a genuine 60w x 4 (rms) amplifier wired to a Bluetooth controller. Turn sound on-off, adjust volume and go forward or back in the track list, all without a controller on your handlebar.

These are not the cheap amplifiers you will find elsewhere that list themselves as “200w” which are actually more like 30w. This is a real class-D amplifier with a high quality Bluetooth controller. It will drive four of our speakers perfectly (or one set of Quad 4), and is already adjusted. Just install and go.

Installation consists of power, ground, and four speaker leads. VERY simple. The only tough part will be mounting to your bike. Every bike is different, but the box is a common Harley Tool Kit, so if you can mount one of those, you can mount this.

Each one is hand built by our staff, just like the ones we build for our in-store customers. You’ll receive the same pre and post sale support. Don’t hesitate to contact us with questions.

Great small amps for mono applications where you need a lot of power in a small, efficient, full featured amp.  I’m listing these by the RMS power I’ve verified them at, not at their factory rating.  Use these when you’re doing a MEGA system with serious subs (top trunk or trike) as for all other motorcycle projects, smaller multi-channel amps are plenty.

• Class D Digital Mono block Amplifier.
• Full MOSFET PWM Power Supply
• SMD Technology on Double Sided PCB.
• 8ga Power & 8ga Speaker Output Terminals
• High & Low Level Signal Inputs.
• Remote Mount Gain Control Included.
• Variable 35-250Hz 12dB Low Pass Filter
• Variable 10-50Hz 12dB Subsonic Filter
• Variable 0-12 dB 45Hz Bass Boost.
• Total Harmonic Distortion: 0.5%.
• Frequency Response: 20-150 kHz.
• Signal-to- Noise Ratio: 70dB
• Damping Factor: > 250
• Input Sensitivity: 200mV-6V
• MINIMUM SPEAKER IMPEDANCE: 2 OHM ONLY

These little amps are great special purpose amps for when you need 4 channels of real Class D power in a micro small package.

Unlike a lot of motorcycle amps this size that are advertised as 50w per channel but actually only put out 14 w true RMS power, these little amps really do put out 60w RMS into all 4 channels.  We’ve tested these on our Amp dyno, so this is the real deal.

They fit inside a Harley Chrome tool kit that you’d put on the side of the bike, and they’re great for powering 2 or 4 handlebar or crashbar speakers.  You do need to properly adjust the low pass crossover, as they’re not going to give you a ton of bass, and have a limit to how hard you can drive them before they temporarily limit themselves, but for their size, they are amazing.

EVERYTHING you need for excellent sound from you handlebars!!!

This all-in-one package has a Bluetooth receiver, with buttons for volume control, track forward and back, on-off switch, 100w true RMS class-D amplifier and 2 full marine Polk speakers all in one package. See video for picture of latest model.

To say that this is the BEST all in one system would be an understatement.  All others are just toys.  The quality of this hand-built system is miles ahead of the rest, and the sound quality is simply incomparable.  We’re simply the only game in town with a true 100w amplifier and real high end marine speakers.

Very simple to install.  All you need is power and ground (a good 15amp source). We recommend running straight to the battery.  Turn it on, link up your phone to the bluetooth and you’re making music.  We’d give you more details here, but there’s just not much more to say.  Everything you need for loud, clear sound on your motorcycle.

If you’ve never tried any of the other self contained systems, you might not understand just how amazing these are.  You can hear them loud and clear at twice the speed of any other system.

These are sold with high quality chrome clamps.  Please measure and choose the correct size.

Housing is 9 x 5 x 5.25in

Hand built in the USA.
