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, 4A 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, 5A • 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 5 out of 5 by from Great little ampI made an iPod speaker out of an old suitcase. Put in a 6.5" woofer two 4" mid bass and two tweets. This thing kicks!

Rated 5 out of 5 by from Good little ampThis is being used to drive two small speakers and a subwoofer to add two more channels to an organ. So far, it's worked well and I'm pleased that I can use its crossover to match the speakers

Rated 5 out of 5 by from Great for a cheap speaker systemIn combo with some cheap dayton speakers, works as a great substitute to expensive computer speaker sets (and far more versatile)

Rated 5 out of 5 by from great for a mini systemI bought this amp along with 2 tectonic 3 1/2 full range speakers and a peerless sds 5 1/4 sub-woofer. Enclosed the speakers in sealed boxes. Took them to work to use when doing overtime. System works awesome and much complements received

Rated 5 out of 5 by from Decent little amp.Been using this for a couple weeks on a pair of Bose 301's and a custom built polk 6.5" sub. Works very well for low to moderate volume. I don't like the fact that the sub level control is separately control from the main volume control. Sub level has to be changed independently unless I do all volume controlling from the main source (PC).

Rated 4 out of 5 by from Good sound for the priceIt's a good amp for the price. It has a subwoofer output. I connected it to my tv audio output. I recommended.

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.

my old CSW radio died, has 2 - 2" speakers (full range?) & 1- 3" (sub?). The speakers sound great in the case. I want to convert to iPod dock. Easy to get to speaker wires. So wondering if this might be the right amp? Think spkrs are only 2W

What speakers would you recommend? Tryn to make a boombox

Asked by: p78580
There are literally thousands of possible options for this kind of application, so one recommendation is not possible. I would recommend checking out our Tech Talk forum for possible ideas, there are many different portable boom box builds there.
