I sometimes ask the the smart-arses salesmen and you cant believe how ignorant they are. And they insist on what they say!! I love it when they cant answer to technical arguments. I dont like them because they use the customers' ignorance and flood them with tech terms even themselves dont understand, just to impress them and sell products the customer dont really needs.
Gunny DONT touch anything from your sound system unless you have real business to do. Probably there is nothing to adjust, but if you do it, make sure you dont leave any marks unless you re out of warranty.
Either way dont try to dismount the speakers unless you are about to change them. Removing the door's trim is tricky, you might leave marks on the door's handle trying to remove the allen screw plastic cover it has there.
Reading my posts again.. i might have a difficulty explaining things with simple words, the trick about the amp is that it cant have bigger output(speakers) than input(power supply). If it has a 10A fuse, you multiply it with the 12V of battery (13.8V if the engine is running) to find the input power, thats 120Watt. 60% of that reaches the four speakers, thats 72Watts at all four speakers. Divide it by 4 and you have 18Watts rms in each speaker.
And these are MAXIMUM values, because the current never reaches 10A since the fuse always has a bit higher value than the needed electic current in normal operation.
