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.

Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output
Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output is rated 4.0 out of 5 by 44.
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.

Rated 5 out of 5 by from Works as advertisedHave only had this for about a week but it sounds great. Took a little bit of tweaking with the sub volume, x over and the Treble / Bass to get it to my liking.

Rated 2 out of 5 by from like others have said - you get what you pay forFor a 30 dollar amplifier this thing does surprisingly well. But you won't confuse this with something costing more money.My unit also has the subwoofer outputs that rumble like mad. Not sure if this is a DC offset problem or something else. I might crack it open to see if there are any adjustments inside. At this point the sub outputs seem unusable. Also the subwoofer controls are completely separate, so any volume changes would need to be done on the input signal, not at the amp volume control, or you'll have to change both the main and sub output levels.The product manual in the box is 100% in Chinese, which isn't a problem in itself. The problem comes when the manual linked from the product page really doesn't describe this unit.

Rated 2 out of 5 by from Subwoofer Amp Makes A Rumbling SoundI bought this amp along time ago, and it's going to be replaced with something better ssuch as the Dayton Audio SUB-800 for deeper bass. I have had it over time, it was great when I first got it, today and yesterday it's making a scary rumbling sound that irritates me alot and gives me a headache and I have to bump it back it place to get rid of it. Good thing it does not hum or buzz, but still it makes that annoying rumble effect and when you touch the trimmer pot it makes a loud popping sound sometimes. It seems that the trimmer resistor on the front is wearing out and I am due to buy another one soon for my DIY subwoofer projects. The sub that I have did not produce deep enough bass vs the other subwoofer I have with my living room stereo and bedroom stereo. I wish that this amp would be improved with better potentiometer controls instead of trimpots for the subwoofer amp and crossover.

Rated 3 out of 5 by from work in progressI have purchased a number of products from Lepai and found them to be lacking. Because of the low price, there are low quality components and the power supplies can be different ones sample to another. The are a good basis for a DYI PROJECT if you are willing to do some work and component sourcing. What these amps need is better documentation, mine came with minimal documentation in Chinese. A forum or group where people can discuss mods, updates, etc. Would be helpful. If you are prepared to add about 30 bucjks and some work, these amps can be quite good.

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.

I would like this to power 1 6.5 inch bazooka tube in my car for a little added bottom end. its a 100 watt 6.5 sub. and will run on 12 v. will this work in a car audio application. and can i use hi power inputs or do i need a high input to RCA boc.

Asked by: masterjr33
This will work fine with a 12VDC power source but it will require a line level (RCA) type input.

Can i install this in my car?  Most cars have 12.5 volts with the engine off and 14.5 volts with the engine on.  Will I run into any problems?  

Asked by: loveBASS
Yes this will function perfectly fine in a vehicle.

do you have eny mini amps like this for desktop type?

Asked by: saranga
This and all other Lepai and small Dayton brand amplifiers are designed for desktop use. It resembles a car amplifier, but it is not one.

Concerning LP-168HA amp (20x20w +78w sub out)  Can I use a laptop power supply rated at 15 watts and 5 amps? 

Asked by: Hank44
As long as the power supply falls within the voltage range of this amplifier it will work. There will likely be no noticeable difference in output between a 4A and 5A power supply.

Max line level input signal for RCA channels for this amp?

What is the max line level input signal voltage for this amplifier for each RCA input? Im running each RCA input with 1.2V off my macbook pro's 3.5 mm output jack (Macbook is the Pre Amp). If I get a line driver and boost the signal to say 4V per channel should this help with getting the amps temps down by using less gain on the amps? Im also using 15V 8A switching regulated power supplies for each amp and both amps are seeing 8ohm loads on all outputs. I have an SMD DD1 to check for distortion and the line driver I'm thinking of using has a Signal to Noise Ratio of 96 which is good, and is capable of 10V per channel. Sorry for the long post just want to get as much info as possible out there for my set up, so I don't damage the amps with to high of an input voltage. Thanks for the help.
Asked by: Harrison
I would not exceed 2 volts/ channel input signal and 1 power supply per amp.
