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.

Where can I find the product spec sheet? I can't believe they only give the 2-11/16" x 1-5/16" measurements of the board as if there is no height measurement which is needed in compact installations. Thank you in advance.

Asked by: tayglo

I am powering the amp with two 6 volt 4.5 Ah/20HR sealed lead acid batteries hooked together for 12 volts, do I need to use a regulated power supply between the batteries an the amp? And will this power 2 Pyle PHSP4 Horn Speakers ?

Asked by: brakemanbob smith
You will not need any type of regulator between the batteries and amplifier. This will power those horn speakers without a problem.

I want to use this as a mono amplifier to run a single full range driver. I understand that it can't be bridged. If I only use one channel, will I only get 1/2 of the output power of this unit?

Asked by: JessieV
If you only use one channel, you will still get full power into that channel depending on impedance load.

if im running a 2 speaker with crossovers and tweeters, should i still be using the caps provided ?

Asked by: grant123
You can try it with and without the caps. Chances are you won't notice a difference either way.

Can I bridge both output channels together to power one 50 watt speaker using the dayton dta-2 amp module??

Asked by: bryan321
No, and doing so will damage the amp.
