is there anyway to test the amp without replacing it first? and of course the stupid question is where is it located.The previous owner of this poor merc did little to no maintinance at all.The good part of that is it makes it the perfect project car but still a shame.With the help of this forum i have rebuilt both seat control switches, have gotten the power windows to function, the stereo works now, and the euro lights. Thanxx to all for all the help.
