Yung SD500 500W Class D Subwoofer Plate Amplifier Module No Boost

why don't you turn it down those who've owned home powered subwoofers no a lot of times the amplifiers when these go bad it's what happened to my Boston Acoustics er 400 you see here instead of trying to take this amplifier out and fix it actually did look at it didn't see what the problem was I decided this is a good opportunity to buy a couple of new plate amps and let's compare them so that's what I'm gonna do today this Boston CR 400 is from the late 90s you can see uses a 75 watt amplifier an 8 inch sub I actually purchased two amps to compare one is the young SD 300 both these were purchased from parts Express the young was a hundred and nine dollars on sale prices may vary at the time of your purchase but the young is a Class D amplifier and I'll show you unboxing in here very lightweight very simple no frills and yeah 300 watts of four ohms quite a bit more than the Boston needs
