#1 Speakers Flea Market 20 bucks for pair (visual inspected before bought)
#2 Car AMP 10 bucks
#3 power supply (garbage)

Notes: The car amp is a beast 550watts (not real) these things are Plentiful, yard sales, junk yards
this unit uses 12v dc, it’s a car install. One issue I came across is the power supply I have is 3amp and when I crank it up the amp turns off, my guess not enough amps, still the loudness is not a problem so I am not looking for another one. This is a brick, says LG so it’s quality

Make sure you look at the power supply output for the DC indication, it’s represented by a straight line.
The Power Amp needs a power feed to the REM, same as the input, this tells the amp to turn on

UPDATE:

I found a XBOX power supply. This thing has 16.5amp output . Fixed the amp quitting but way loud

Remember the powe brick has to be jumpered to turn on
