Review: Awesome little amp! (as long as you use a proper crossover) - There are plenty of reviews detailing the features of this amp, so I'm going to discuss my specific setup, what worked for me, and what didn't. I purchased this amp to power the audio for my Burning Man bicycle, which is using a Tang Band W8-670C 8" 8ohm subwoofer in a ported enclosure, and two Tang Band W3-594SB 3" 8ohm drivers in sealed enclosures. MOSFET's, heat, and thermal paste My amp doesn't get very warm, even after an extended period of music at high volume. Several other reviewers reported poor factory application of thermal paste, so I was concerned that the heatsink wasn't getting warm due to the MOSFET's not making good contact. I opened it up to check and they looked just fine, but I went ahead and re-applied some thermal paste for good measure. After doing this I haven't noticed any difference in performance or temperature. Crossover The LPF crossover is a total joke. Mine "works" in that I can hear an audible change in the subwoofer output as I turn the knob, but the amp still sends the subwoofer nearly full-range input. Using only the included crossover, the overall audio quality is mediocre, and both the subwoofer and drivers were clipping well below the volume I had hoped for. I ended up purchasing a 225hz LPF crossover (http://www.desertcart.com/gp/product/B00FNI3N4Y/), and it made a world of difference. The overall volume can now get much louder without clipping, the subwoofer hits harder, and the drivers sound great. With the crossover installed, this no longer sounds like a cheap ~$30 amplifier. If you are using this to power a subwoofer, do yourself a favor and get a crossover! You won't regret it! Power Source The included 12V 3A power supply works acceptably, but prevents the amp from reaching full volume. I've had the best luck with either a 12V 5A power supply, or a 12V SLA battery. Checking with an ammeter, the highest current I saw at full volume (with a bass-heavy track) was just over 4A @ 12V. Rattling I have this amp mounted on the subwoofer enclosure, and I quickly discovered that it likes to rattle. All of the knobs rattle, as does the case. The case rattling can be solved by putting some hot glue on the inside of the seams where the case pieces attach, but I'm still grappling with the rattling knobs. My "best" solution so far is a piece of electrical tape stretched across the tops of all of the knobs, but I'm sure there is a better way to do it. Audio Input Levels One unexpected problem is that a high input voltage is required for the amp to reach maximum volume. I first used a second generation iPod Shuffle. This worked in that sound came out of the speakers, but it just didn't get particularly loud. I then tried two modern Android phones (an LG G2 and an HTC One M8). The HTC produced the highest volume and clearest sound, but both it and the LG worked pretty well. You should try a variety of input sources if you're not happy with the volume. Final Thoughts Buy this amp (and a crossover)! I wasn't expecting much from a sub $30 amp, but it's a surprisingly cool little device.
Review: Great Value!! - I received this in good order. hooked it up, The high end (top row) of speaker outputs works beautifully, the sound is full & clear...as I hoped & expected just as it is from my LP-2020A+, the sub/low end hook ups made a strange popping sound & I wasn't sure why, thought there was something wrong with it & it needed to go back. as it turns how you hook up the sub is strange. After I hooked it up properly the popping stopped & it was VERY deep. the power supply this amp was sent to me with is inadequate for the power needs of the unit. On the back of the unit it says it needs a 14.4V 5amp power supply, it came with only a 12V 3amp power supply. so the thing needs to be shipped with the proper power supply. Why Lepai can't get their ducks in a row on this power supply thing eludes me BUT I shopped around & for ONLY another $8 got a new power supply that meets the needs of the amp. There's a little blue light on the front next to the bass settings that acts as a 1 light 'EQ' blinkie kinda thingy. It blinks according to the pulse (bass) of the music coming from the low end. It's irritating as all hell. It blinks far to brightly to NOT cover up...it's obnoxious enough to put someone into a seizure...considering it's under my desk it's not to bad though. UPDATE: It's been a great work horse for my computer desk sound system sub-woofer (bottom row of the speaker connections which is bridged) & my "highs" (top row speaker connections). I have a different amp (Fiio A1) powering a pair of Micca MB42 Bookshelf Speakers (full range mids). HOWEVER after a year of use the left channel has begun to "go out". works sometimes, then doesn't others. I little jiggle on the line & it's working again. I think something is going on with the connection on the inside of the amp. why this is I am not sure. It has stayed in one spot for the entire time I have had it. it is mounted ON the sub so that 'may' have something to do with it due to vibrations. It's worth buying another one, so I have. I am going to use this amp with a bad channel strictly as a sub amp for my living room to power a 2nd sub for my entertainment system.

## Questions & Answers

**Q: Hi, great product but it has a whistle sound thats annoying me, any way to fix?**
A: Through the speakers I'm assuming. Generally I'd try it with different speakers, but it could be a bad unit. It sounds like interference.

**Q: How do you apply thermal paste to the mosfets? Does it require desoldering or is it just a screwdriver task?**
A: Just a couple of screw drivers.  Unscrew the silver phillips head screws on the front and back of the amp to permit you to remove the circuit board.  Also unscrew the bigger black phillips screw on the side.  That holds the clamp that braces the mosfets against the heatsink.  When you pull out the board, you'll have access to the chip to apply the thermal paste.

**Q: How would I wire this for power in a truck since it only comes with the household plug?**
A: The Product Description clearly states that it IS intended for automotive use! You DO NOT need an inverter; the unit runs on auto voltage; it has a power adapter which takes the 120 AC house current down to 9 to 14.4 DC. Just throw away the power adapter which comes with it and wire it directly to your vehicle (12-14 DC).

**Q: Could you power this amp by just the usb port? if i plug it into my computers usb port will it power it?**
A: Actually, the amp's USB port is a 5v powered outlet for another device.  In my application, I use it to power the stereo's bluetooth module.  The amp itself requires 12v from either the included AC adapter or a 12v battery.  Hope this helps.

### ⭐⭐⭐⭐⭐ great little amp, big sound.
*by B***Y on January 22, 2014*

I have owned a lepai 2020+ amp and loved it with a grounded 6.8 amp power supply, it sounded great with my bookshelf speakers. Unfortunately, the volume and tone pots are poor quality and eventually it output nothing but static and thumps maxxing out the excursion on my speakers. Here's where this comes in. I wanted a little more "oomph" on the low end with the same speakers. I found this amp with a dedicated crossover and sub out. For the money, it was worth a shot. I ordered it and it arrived quickly, packaged great. I dismissed the power connector that came with it and plugged in the adapted from my deceased lepai 2020+, plugged in my bookshelf speakers and a Sony 8" home theater woofer. I was very surprised with the output on the low end! Very very solid bass, loud and clear with this tuned port sub. Actually have it turned only 1/4 way up and fills the room with nice clean lows. The mids and highs however, aren't as defined as the 2020+. Should that deter you from picking this up? It is a small sacrifice to make. If you have excellent bookshelf speakers that reproduce sound well, the 2020+ is a great buy with a grounded transformer, just dial it in and leave it. Adjust the volume with your device. If your speakers lack lows and need backup, this amp has the power to deliver. I am very pleased with this and if it bites the dust in a year, I will happily purchase another. A few negatives though, the led lights on the front panel are blinding. Really REALLY bright. The sub out light is blue and for some reason flashes with the intensity of the subs output. They are covered with electrical tape and haven't been a nuisance since. Also, the sub out frequency control is just a dial, it makes no discernable difference in range. Mind you, no mids bleed through so its not a problem for me, even at high volume levels. All in all, I would buy this amp again.
