Connecting an in home powered sub to car radio?
I'm trying to use my subwoofer, powered by an outlet in my car. I managed to open it and splice the speaker connection to a 12 inch subwoofer speaker and get great sound, but thats with it in the house, connected to an out let.
I took the internals of this amplifier and connected it to the speaker box, so it would look legit. The problem that I'm running into is powering the thing
I don't want to go out and buy one of those power converter components, but would rather get it to work and look as though it were made like this from factory.
It's performance is awesome, from what was herd, but retrieving the power to power the thing from my cars electrical system is now the biggest challenge. Can any one help me with this one??
1) Transformer was retrieve and detached from enclosure. Mounted to inside of box.
2) Sub Equalizer was mounted to box inside
3)My car's cd player comes with a preamp

well its not really different house vs car, the only difference is that house speakers have much larger boxes and require less power due to that reason..
ALL electronics run off of DC power, it varies the amount of power the device uses.. just about everything you plug into your house outlet is ran off DC power in the end, it is a better power source but harder to transfer long distances, the reason for AC power, if you get a multimeter and find out how much voltage comes out of your step down transformer in your new amp you can figure out what you need to do, if it is 12v or less it will be easy, 12 v would simply require you splice in a 12 v power source, if its less you will need a voltage reducer, and if ifs more then you will have to find a way to increase the 12 v that is provided by your cars electrical system, none of these solutions should be that hard or expensive just require some research and maybe electrical knowledge
