Question: Would this be good to use with a pair of bass shakers?
Document: I bought this to use in a parade on a robot! I am part of a FIRST Robotics team who built a robot to drive in our local parade. The robot runs off of a 12v battery and we wanted a lot of bass so this was the perfect option! We connected it to a pair of speakers with subs built in and it worked like a charm. It did get a bit quiet when the battery started to get low, but that is to be expected.
I tried this amplifier with two speakers and a sub and the sound was horrible and very low power. Much to much bass. I had to return it there is no way to use in a car or boat you would never hear it when the engine is running.
I now have both the Lepai 2020A and the LP-168HA. I have been running the 2020A with a pair of 50 watt pioneer speakers and it does a good job with my Nano 16 gig. I do not have young ears any longer and at the volume I listen to; this is a pretty good matched set.
Use the smallest speaker leads you can, and they should be OK.My final complaint is that since I use this with a PC, when I start up or shut down the computer there is a rather loud THUMP sent to the speakers. This doesn't happen turning the amp on or off - it's only when the Sound card fires up or shuts down. You may want to turn the amp on and off manually to avoid this.Would I recommend this unit for a living room stereo? No.
Excelent Productwhy 4 star the subwoofer freq its bad for music good for moviezwith this amp use 2 Altec Speakers and 12&#34; subwoofer and so happy with this
Yes the subs can handle MUCH more power, but for what they are getting, you wouldn't know it's so low , you would think it's just turned down. I have one sub that vibrates the couch with out a problem when watching movies/TV & listening to music. so it's doing the job I intended it too do. would I buy another one.? Yes.There's a little blue light next to the bass settings that acts as a 1 light EQ blinkie thingy.
Not too loud and good for the garage man cave. I may also use it on a tailgate cooler project but we'll see. Good clean sound and easy to use and thanks to the amazon info online on how to set up the sub-woofer.
I bought this unit to replace a power amp in expensive computer speakers that powered 4 satellites and a subwoofer. It was far less expensive than trying to get the unit repaired, and to find a similar high quality speaker set would run $150 to $300. I didn't have the problems with the crossover that many mention - it seems that most of the bass goes to the woofer, and mids and highs to the satellites. I also didn't expect this unit to provide anywhere near the advertised power.
First off, I bought this amplifier for home use. While compatible with cars it works for home use as well.I bought this amplifier to power my vintage RtR G-40 speakers and my Kicker Comp-10 subwoofer. Installation was incredibly easy, just plug in, connect speaker wire and you're good. For about 2 or 3 weeks it drove my speakers great.The sub, however, was terrible.The biggest feature here for the product (to me) was the subwoofer crossover.
The specs don't seem to match up, I did testing and the output (literally dependent on power supply) had a max of approx. 15W x2 and for the sub was about 30W (6W RMS x2 @4Ohms, 15W RMS x2 @4Ohms) power supply seems inadequate for the amp it comes with so I'd recommend you to get a higher current 12V DC power supply to use this amp at full potential. Overall is a good mini amp for desktop PC, TV, workshop sound system, etc.
Answer: No.  This is essentially a low power portable amplifier. I'm not sure how the calculated their wattage numbers but they didn't use 'math'.  For instance, maximum safe input is 5 amps @ 12 volts.  That is 60 watts input.  After conversion losses (let's be super generous here and say 85-90% input power gets converted to audio output) you have a maximum of 50 watts to split between 3 channels.  Not enough for any kind of large load like a bass shaker.
