300w amp with a 300w PSU ? Will it work for a few months ?


Nov 11, 2012

The PSU would have to be a CHEAP CHEAP one witch is over powering the AMP so im not under voltage

Computer psu are not designed for audio power amplifiers. You need a 12 volt supply but the current requirements are far greater than a PC would need. Something like this is more like it
or consider buying an real home audio amp for the sub. Don't worry about the power being 300w as car stereo is usually overated. Depending on the sub get something around 100w and it should be OK.
