Hi all,
I recently bought a 300w sub with a broken power board for 15 quid.
I stripped out the power board and the fancy low pass filter, frequency modulator, and volume control board out. Then bought an L7 MOSFET mono power board that supports 300-350 W at 8 ohms as well as requiring 2x 50 V in, this is exactly what the transformer outputs and what the driver requires.
I also picked up a 2M ohm potentiometer for volume control and a 100Hz or so highpass/lowpass filter (i always get it the wrong way round)
because it's a mono out board I'm having a lot of trouble trying to work out how to correctly wire it all?
Any help?
Finlay.
