i have a small audio amp from a Cana-Kit. it is the Uk193. it is a 20W Bridged Power Amplifier.
the supply voltage for this unit is stated as
Supply voltage: 12 to 18V DC / 2A
now what i have used is 2 small 9volt batteries (those like duracel that you put in your smoke detector). this amp is hooked up to a small horn/speaker (15W). now when i turn on my MP3player (i.e. ipod) and turn thevolume up, the unit cuts out and does not play music until i turn the volume down. However, when i hooked up my Ghetto blaster or my computer to the audio supply to the amp, i could turn up the volume as loud as i wanted.
However, if i hook this same amp to a 12V car battery i can turn it up very loud when using either the Ghetto or the mp3 player.
what does it sound like is causing the problem.
any info much appreciated.
