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 dedicated subwoofer output capable of up to 68 watts of amplifier output. To connect a subwoofer simply hook them up to either the left pair or right pair of bottom row spring terminals; both are the same because they are wired in parallel.

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 MisleadingThis amp doesn't come close to the wattage claimed.The distortion level is extremely high at upper volume range.It only delivers 7 or 8 watts before it starts distorting.So if you can live with distortion or low wattage, go for it.Other wise, save up more money, and buy something of better quality.

Rated 5 out of 5 by from Surprise of the year.Just hooked up this little gem to a sonotube mounted 8" woofer and a pair of my cabinets loaded with Eminence drivers that I use for PA events. I am chuckling with delight and disbelief the this sub 30$ unit is performing the way it does! It's applications are endless! We are hosting a party at our cabin retreat this weekend. It is off the grid. The sound here is beyond impressive. PE is without peer.

Rated 5 out of 5 by from Jack it up to 12V-5A and it's a winnerWith its included 3A power supply, the Lepai LP-168HA is an adequate little desktop amp. And, considering you bought it for the price of a Happy Meal - and momentarily disregarding this little amp's quirks - adequate is okay. But swap out Lepai's 3A power supply with a 5A number, and you can say goodbye to adequate and say hello to something completely unexpected. Loud.No, it won't be molar-rattling loud. But it will be loud. Loud enough that you'll want to ratchet the volume down on the iPad (or whatever) and set the amp to "5" or so before daring to flip the switch. Forget, and there's a good chance the neighbors will come knocking. And with a separate volume control for the sub, forgetting comes easy. Which is one of this amp's initially annoying little quirks.The master "volume" knob doesn't do sub. The sub control is off to the left, next to the microscopic 50Hz to 200Hz "X-Over" dial-ette. This bipolar configuration and its particle-sized knobs will eventually grow on you and, oddly, begin to make some sort of sense. Until it's 5 a.m., the family's asleep and you once again forget. Just remind them what you paid for the thing.As to the important stuff, the amp out-performs just about anything else you won't find at this price point. The sound is remarkably clear. And those two otherwise choosy 80 watt yard sale GC Electronics bookshelf speakers seem to like the thing. It even arouses the 200 watt JBL sub (especially when it's 5 a.m. and you once again forgot to crank down the mini-dials). And while the mileage seems to vary on this one, the cross-over works as advertised. The USB charger doesn't, but who cares? Either does the "manual," unless you're fluent in Mandarin. But again, who cares?A final note for those who still aren't convinced. I rigged this amp to temporarily power the 16 ohm Alnico "tweeter" that feeds the upper rotary horns on a recently overhauled vintage Leslie organ speaker cabinet. It somehow managed to keep up with the 300 watt bass speaker bolted-on down below. And it did it without a whimper, remaining at room temperature despite having to overcome all those 60-year-old ohms. Score one for our friends in the People's Republic.

Rated 5 out of 5 by from Boombox DIY with CD Bluetooth!The 8 Inch sub and box paired with this amp and two mid-high speakers, Danibose bluetooth, inverter, and jump box will be portable and sound fantastic for a low price. Bam..home stereo on the beach, streaming tidalhifi.com in offline mode via CD quality bluetooth! 30 for amp. 21 for Danibose and 150 for 8 Inch box and sub, 150 for 12v jump box, 20 for inverter speakers vary. Enjoy!

Where can I get a power supply that can power this amp at 5A. and when it says down to 2 ohm that does mean it will be fine with 2,4,6,8,16 etc. right? thanks.

Asked by: ljk2000
Try here for the 5A. Power supply: https://www.parts-express.com/12-vdc-5a-switching-power-supply-with-25-x-55mm-plug--120-056You'll need a new 2.5 mm plug here: https://www.parts-express.com/parts-express-25mm-x-55mm-plug-for-ac-adapter--120-086Regarding the "down to 2 ohm" language, one would think so but I'll yield to someone more knowledgeable than me on that topic.

Is this unit supposed to be on while the power switch is in the off position

Asked by: mdmd
I believe that the light could mean that there is power going to the amp

Is there a way to adapt this for automobile use?

Asked by: Jack327
This amplifier is powered via 12VDC, so any 12 volt power source in the vehicle that can supply 3 amps or more will work for this.
