The LP-225 mini-Bluetooth 5.0 amplifier mounts in almost any location because of its size. Its main body size of 3.5" x 2" x 1-7/8" enables it to mount in glove compartments, indents in dashes, or other areas in multiple types of vehicles. Set the controls and hide it away or expose it for sound customization for each song. Use the four holes in the 3/8" x 1-7/8" mounting tabs to secure it for a more permanent installation. LP-225 includes a 3.3 ft. 20 AWG DC cable with a 2.1 x 5.5 mm tip positive plug to connect to a fuse box or other 12 VDC source. If using a 24 VDC power source the speakers must be 8 ohms.

Lepai LP-225 may be a mini amplifier, but don't let the size fool you. It cranks out 25W RMS/channel which makes it perfect for most automotive speakers from 3-1/2" up to 6" x 9". Hookup the LP-225 to vintage bookshelf speakers made for car or home like Minimus 7, 77 or other metal enclosure types. Add an optional 12 to 20 VDC AC adapter to crank up any home bookshelf speaker that might be able to handle 25W RMS.

Create your own powered Bluetooth speaker with vintage bookshelf speakers that you have or buy new ones instead of buying an amplified plug in Bluetooth speaker. The low-cost LP-225 mounts easily to most wooden bookshelf speaker enclosures and Bluetooth 5.0 lets you wirelessly connect to the speakers via your smartphone, tablet, computer, or other Bluetooth media player. You may have a 12 VDC 2A 2.1 x 5.5 tip positive AC adapter from old computer speakers to power it. If not check all the options for power below. Add a powered subwoofer to the preamp line output on the LP-225 to add extreme bass to the bookshelf speakers. Bass and Treble controls still effect the line output, but the volume control only changes the LP-225 speaker outputs. Changing the source volume effects both the line output and the LP-225 speaker output at the same time.

Pairing Instructions

Pairing your Bluetooth device to the LP-225 is very simple. The Blue LED flashes on the amp when looking to pair with a Bluetooth device. Go to the Bluetooth settings in your device and start scanning. Select the LP-225 in your list of found items. The Blue LED on the amp will turn solid when paired successfully. There's no strange voices or beeping sounds when paired. You might need to use the pairing button on the amp to unpair other devices previously paired. When using the line input on the LP-225 it cuts out the Bluetooth for non-Bluetooth sources.

As you can see, Lepai LP-225 works for many different applications. To get the most power from home bookshelf speakers use the 19.5 VDC 3.33A AC adapter sold separately.

Its lightweight, durable aluminum shell holds up to rough environments which makes it perfect for many automotive applications. It includes a DC cord to wire directly to the fuse box. Add an optional car lighter/accessory plug to the included DC cord to make it movable between vehicles.
