Yamaha YST SWO15 Subwoofer Project/ Questions.?
I recently acquired this home powered sub woofer for free. I already have other units set up for my system so I was thinking of converting this to a car powered sub woofer via power converter.
Will this drain too much power from the alternator or battery?
The sub is rated 70watts@5 ohms.
Does this mean the speaker in it has that specs?
I opened the rear of the unit and saw that there is a power converter in it.
Does anybody know what voltage it is converted into? Maybe I can just remove the converter and make it work with 12volts.
It already works with a power converter that I already have (12 v/dc to 110 v/ac). I am just worried it will drain the battery or put too much load to the alternator.
Worse case scenario, I'll end up just using the box only, I already have a car amp and speaker just laying around.
So I went ahead and opened it up and tested what voltage it actually operates. The transformer inside the unit converts the 110 volts AC down to 27 volts AC. This is what I was trying to find out. So I guess, I'll just keep it the way it is via 12v dc to 110v ac converter and see how it handles.

It will not work. Period. Don't even waste your time and money on an inverter and the conversion to 12 volts is not even possible.
There are many reasons why home audio and car audio need to stay in the home and in the car... this is why. Maybe consider selling or trading the Yamaha for a proper car subwoofer?

The driver inside the unit may have different specs...The specs for the speaker include any crossover the unit may have installed...so the bare driver may have a different ohms rating and power handling capacity also the frequency response could differ.....Also a 12 volt ohms rating and a 120 AC ohms rating are not the same thing they have different characteristics....Its possible the driver would work in another enclosure but its hard to say with out knowing the specs for the driver alone...You may be able to find those on line if you know the make and model number for the driver alone...or you could test the driver and determine the specs...or you could just roll the dice and hope for the best.....although if you do that its possible that you could damage the driver or your amp or some other unforeseen accidental damage...
