Amplifier hook up

Almost all home theater receivers or processors and some stereo receivers have this type of subwoofer output. It's usually just one cable with single RCA connectors on both ends. Sometimes you'll find that a receiver or amplifier does not have the LFE subwoofer output. Or it might be that the subwoofer doesn't have the LFE input. Or they could be spring clips like you'd see on the back of standard speakers.

Hello everybody, recently i bought car amplifier for repair and decided that im gonna replace my Sony XM that i have been running as my subwoofer amplifier for a year now. I took this opportunity to write instructable on how to properly hook car amplifier for use inside of your house connected to mains voltage and what you should be careful about. There are many reasons why you would want to use car amplifier, but if you can choose between proper vv amplifier and car amplifier i would suggest you to pick house amp, its power supply is well designed and you will get proper power output out of it. Car amplifiers are mostly rated at 14,4V and lower impedances 1 or 2 ohm for example while some home amplifiers can only go as low as 4 ohms. Since you will be running it off 12V power supply more about that in further steps you might not get as stable power as you would in your car. If you however still choose car amplifier then continue reading as i will try to provide as many information about it as i can.

So here's my attempt to shed some light on this. They are really just a relay contact and isolated completely from other circuits, so the polarity between the two doesn't matter interchangeable. Remember that COM is floating and has nothing to do with the circuit ground. See schematics at the end of this article for details. RX status is not 'Low' or 'Ground' but ' undefined ' floating.
