Help replacing the amplifier in a powered sub woofer?
I have a Phillips SW 900 powered sub-woofer. The internal amplifier board has broken and I need to get a new board or an equivalent amplifier. The internal subwoofer is a 6 inch 4 ohm 40w driver.I don't want to spend any more than around 50 US dollars. The only connection that I need is one RCA jack for audio input.
