Rated 5 out of 5 by from Worked perfectlyBuilt the rock n dock for two of my grandsons and they performed perfectly. They will both enjoy the sound at Christmas

Rated 5 out of 5 by from Can not be beat for the price!Pushes my B652's very well in a boombox I made. Volume knob is a handy feature. The overall unit is very small. Its nice to have a small amp with a nice sensitive input. My Sansa MP3 player can drive this amp easily without having to peg the volume. I plan on buying more for other projects.

Rated 4 out of 5 by from great ampi build and sell speaker systems using cigar boxes as the enclosure, i used this amp in a 4 spk and 2 tweeter setup along with a external blue tooth and rechargeable battery it sounds great.

Rated 2 out of 5 by from Good little amp, but...This amp produces good sound, but it wants to amplify unwanted sounds too. I used the ferrite chokes and capacitors that were included as per directions. However, it is picking up some signal (perhaps from the Bluetooth receiver?) and it is very distracting! I'm going to enclose it in aluminum and/or remove the Bluetooth to see if that helps. If it works, I'll follow up.

Do I have to use the output capacitors ? If I do,do I solder them directly to the speaker terminals on the pcb?

Asked by: BBuck
Use of the output capacitors is recommended. The amplifier will work without them, but the amplifier may produce more radio-frequency interference than desired in a situation where sensitive radio receivers may also be used. The capacitors should be connected in parallel with the speaker loads, after the ferrite chokes (NOT before the chokes! - doing so may damage the amplifier). You should not solder the capacitors directly to the board, because that would place the capacitors before the ferrite chokes instead of after, and this can cause amplifier oscillation, overheating, and damage.

Can this amp be used to make a powered speaker, with an XLR connector for a microphone?

Asked by: Kundikini
Yes, but a microphone preamp will be required in order to use a microphone with this.

Hooked up according to directions.  Pyle 50W horn and 12v battery for power.  Tried playing MP3 through my phone (3.5 jack) and the sound was muffled.  Cut in and out.  At first, it was just very quiet.  I tried reversing polarity but still cut out.
