(More customer reviews)I bought two of these.
After a little research I found they are the units from kicker for a Chrysler 300.
I cut off the plug ran a high level speaker signal to it and nothing happened. I was messing with it for a while and came back here to check what partsE had recommended. Then I noticed DC offset. This is key. If you are going to bench this your speaker level input has to be "seen" by the amps circuitry. I could not get this thing to turn; then I wondered if I bridged a wire from one of the Solid Green or Solid Grey wires to the Negative that would provide the offset seen in car audio installs since chassis is ground. Well come to find out the amp will turn on only if there is a decent strong high level signal and its bridged from the Negative of the power supply to one of the Solid color speaker level inputs. Remove this wire and the amp shuts off. voilà There is your turn on lead.Now performace was tested using a 250V 80 amp Sorensen(Raytheon) 0-20V Power supply and an in line Ammeter (no inaccurate clamps here) I was seeing about 1 amp draw at 15 volts on a low undistored signal. I could not turn it up at the time since it would literally light up my 15 inch Powerbass dual 1 ohm subwoofer I have sitting in the garage. I am guessing this amp wont do 100 watts continuous. With a factory radio driving this amp it may see 60 watts RMS by my quick check of amps x volts. Take that for what its worth.
Just like everything I get... I took it apart and found 6 transistors labled IRFZ44R. After doing a little looking around. These same devices were used to repair Rockford Fosgate The Punch amplifiers in the early 90's among other amps... The Mosfet devices are stamped 424k and 9216 respectivly. Checking the data sheet it means these were made in 1992 week 16. Also a nice set of capacitors and a decent circuit board layout. Built in 23 NOV 2004.
To sum up the small testing I have done I could see powering a dual 1 ohm sub with these or my next test will be to STRAP them, haha, love messing with 10 dollar stuff. I could give a 2 ohm load 200 watts rms strapped and the footprint of these amps are awesome (tiny).
The amp and subwoofer from Kicker would cost you around 500 dollars for the setup. You can get this amp for 10 bucks!
