I was wondering about the watt raiting. I am running about 900 watts in my Murano and I have a 60 AMP fuse at the battery and 20 AMP fuse at the amps.
You won't see much that is meaningful with the multimeter.
The current draw will vary with the music.
Power = volts x amps.
Assuming 12 voltish source at 5 amps your looking at 60watts total power.
Somewhere about 25watts rms or less per channel stereo.
Watts in = watts out + heat.
So watts out delivered to the load is less than watts in.
Since nobody listens to a sine wave at full blast the peak power out may exceed this for a short period of time without violating physics since most of the time for music the power out is less. This is where marketing takes the ball and runs (WAY out of bounds) and prints 200watt "peak music power" or some other made up market speak on the outside of the box.
For a thousandth of a second your 60watt amp is producing 200watts, mostly distortion and is a great tweeter killing device. Speakers are rated for music which doesn't have a lot of high frequency power, amp distortion has a lot of high frequency power.
OK. I have been trying different methods of mounting some 100 watt Pyle waterproof Marine speakers in my 2003 ST1300. I am about ready to give up my tinkering and spend the $56 to get the Honda boxes shipped. They look like they mount on the sides of the windshield support brackets?
Before I do, I note that some of the websites label the part numbers as fitting the 2006-2008 STs. Can anyone assure me that they will fit into my 2003? Mine is not the ABS model, and there is no windshield adjusting mechanism to get in my way. Thanks for any comments...
I have the JENSEN Heavy Duty MINI Waterproof AM/FM/WB Radio which has 3.5mm outlet + 4 wires to connect to the speakers. My amp I bought from China has only RCA inputs and wires out so I have to order a HI/LO convertor to change my radio output wires to RCA outputs which is $20 or so.
