Product Details

Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output

Lepai's LP-168AH 2.1 amplifier is the perfect computer partner—it provides up to 40 watts of power output to stereo speakers, in combination with a second dedicated subwoofer output capable of up to 68 watts of amplifier output.

Bass, treble, and volume controls on the front of the amplifier let you adjust your music for the best possible sound from your speakers. The discrete subwoofer output is controlled separately from the stereo output, with controls for level adjustment and crossover adjustment found on the amplifier's face.

Audio source connectivity is provided via a front-mounted stereo 3.5 mm jack, or a stereo pair of RCA jacks on the rear of the amplifier. A rear-mounted USB port enables charging of devices such as smartphones and MP3 players. The wide input voltage range of 9 to 14.4 VDC allows the LP-168AH to be used in automotive or mobile applications. A 12VDC, 3A power supply is included.

Specifications: • Stereo power output: 2 x 40W max (power output dependent upon power supply) • Subwoofer power output: 1 x 68W max (power output dependent upon power supply) • Power requirements: 9 to 14.4 VDC, 3A • DC power input jack: 2.1 mm x 5.5 mm • Bass and treble control • Stable down to 2 ohms • Minimum THD: <1% • Signal-to-noise ratio: >80 dB • Frequency response: 20-20,000 Hz • Adjustable subwoofer crossover: 50-200 Hz • Dimensions (including mounting flange): 7" W x 4" L x 1-3/4" H.

Rated 2 out of 5 by from not what i had hoped forpurchased this little amps thinking it would have good sound like their LP-2020+ and i was disappointed. the mids/highs are distorted and the sub section is even more distorted. it seems to sound flat by comparison (to the affore mentioned lp2020a+). good for the price but not worth the trouble.

What would be the better ohm resistance to use with this amp? 8ohms, or 4ohms? Also I would only use one subwoofer. Do I have to bridge this amp, or just use one of the two sub outputs?

Asked by: SirHarley
Using 4 ohm drivers will provide the most output from the amplifier. The sub output is paralleled, so you only need to use one set of terminals.
Answered by: MattP
Date published: 2015-03-01

is it ok to run a left and right speaker at 4 ohms each, then two 4 ohm drivers off of the sub portion wired as 2 ohms ?

Asked by: tkroeker
Yes that will work fine with this amplifier.

Can I run Bass Shakers (299-028) off this amp?

Asked by: chitodb
This depends on the shakers you plan on using. The Dayton Pucks will work well with an amp like this, but four Aura bass shakers would require a bit more "beef" in order to use them to their full potential.

What is the blue LED next to the crossover knob for? Is it an overload indicator?

Asked by: SlotCar
It just shows low frequency activity. The brighter it is, the more output on the sub channel.
