Simple Solid State Relay For Low Wattage Class D Power Amplifier

For months I'm playing a lot with  this  tiny amplifier. It is 12 volt capable, low watt, yet ultra efficient power amplifier that very suitable for car audio application. It producing high quality audio with flea watt that most any mid-range or full-range speakers can accept. Previously, this auto power-on amplifier is controlled by using a mechanical relay. It is okay and not any single problem occurs. But to make it less mechanical things, I built the simple solid state relay in it.

The Reason (Not) To Upgrade Your Car Audio System

While for most of home audio people really know well that the car is the worst place for audio, thus listening music in car is unavoidable. The situation for my daily driving activity is about at least 2 hours minimum per day. Compare how much I spending time while listening music at home it quite similar.

DIY RCA To Sony PS1 SCPH-5500 Audio Cable

The Sony Playstation SCPH-1002 is become my main CD player for almost 10 years. Sadly but truth, I cannot find any audio source on the range of US$99 that could match the sound quality to this SCPH-1002. The optical kit of this SCPH-1002 is KSM-440ACM which is become problematic by ages especially when reading the CD's. The optical kit replacement from China is not a good solution. They are not so smooth in CD's playback. Other solution is using others original KSM optical from Playstation scrap which is the best but not an easy solution. The last solution I could bear is finding the complete unit model SCPH-5500 which originally have improved on optical placement and still using the same DAC chip like the SCPH-1002.

The hi-end audio brands are nowhere heard from those average consumer.
