Hey i want to convert my home audio passive subwoofer to be able to connect to my new receiver. I plan on using this instructable: http://www.instructables.com/id/Conv...ofer-to-power/

However, I have a few questions. I plan on buying the same plate amp that the author of the instructable used. here it is: http://www.parts-express.com/pe/show...number=300-782

Question 1: In instructable the first step of the author was "My sub had the receiver/amp built in to the back of it. I removed these parts since they weren't being used and found the two (+ and -) wires to the speaker."

Do I have to do this if the back of my passive subwoofer looks like this?:

Question 2: In step six where he soldered the wires from the sub to the back of the amp, could i not simply use speaker wire from the back of the sub in the previous picture to the amplifier output? Here is an illustration of what im talking about:

Will that work or will i have to do soldering as well?

Please share your advice. Thanks!

Why go through all the crap of using a plate amp?


Just buy any one of the amps out there capable of running it and call it a day...


Sony TA-N110(these are a decade old, you see them on Audiogon and Ebay every once in a while)

Jamo MPA-201(has a crossover and is daisy chainable, there is a version from Dayton as well, same amp)

Question 1:

A plate amp requires you to cut a hole in the subwoofer box, so you can mount it. The driver inside will have 2 wires that connect to the amp. With a passive sub, those 2 wires connect to the spring-clips you have in your photograph. To answer your question: Yes, you need to find the 2 wires and connect them to your new amplifier.


Question 2:

No. Those are not for the sub driver. There will be 2 connectors on the inside of the plate amp that will connect to the sub driver.


If you are not sure about screwing around with the inside of a sub, then do what schan1269 recommended and get an external sub amplifier.


Then again, if that is your sub, and it's a samsung, then it probably isn't really worth the cost and effort of converting it to an active sub. You might want to just save the money and save up for a new sub.
