			=== Couch ===

			* Cut 1x8 to length of couch. Mount to bottom of couch.
			** Secure to couch with both wood glue and screws.
			** This board should be secured well to the couch body.
			** Transmits vibrations across the whole couch so speaker vibrations are not localized.

			* (Optional) Cut section of 1x8 and mount behind cross member.
			** On this couch, speaker would have touched ground if mounted to the cross member.
			** Used wood glue to attach to couch frame and wood glue and screws to attach to cross member.
			* Mount speaker [[image:Transducer7.JPG\|200px\|thumb\|center\|<i>Speaker Mounted</i>]]

			* Add RCA Jack
			** We decided to add a RCA jack to make for easy movement of the couch. [[image:Transducer8.JPG\|200px\|thumb\|center\|<i>RCA Jack Added</i>]]

			=== Amp ===

			* These steps will vary greatly depending on your amp.
			** This is extremely hazardous, the capacitor in this amp stores a large current and can kill you.
			** If you can modify the amp without opening it, that would probably be better.

			* Amp Modification
			** Note clearly labeled warnings [[image:Transducer9.JPG\|200px\|thumb\|center\|<i>Warning</i>]]
			** You can see original design with wires coming out of the bottom of the amp. [[image:Transducer10.JPG\|200px\|thumb\|center\|<i>Opening Amp</i>]]
			** Added RCA plug to top of amp. [[image:Transducer11.JPG\|200px\|thumb\|center\|<i>RCA Jack Added</i>]]

			* Further Modifications
			** We went back and added some active cooling to this amp. We discovered that during use, this amp became extremely hot. This is because it was not meant to drive a lead weight. Holes were drilled in the side of the case on both sides and a 12 volt computer case fan was added. The fan was powered via an external 12 volt wall wart variable voltage supply. The selector on the supply allowed us to dial up and down the cooling depending on demand.

			== Epilogue ==

			You'll probably notice that we are using a KLH amp, and a Pioneer speaker. The amp came out of a KLH sub that we dismantled for this project. We bought it and dismantled it, solely for the amp. There are plenty of cheap 12 volt car sub amps out there, but not too many cheap 110 volt house sub amps. We discovered this after building the transducer and having nothing to drive it with. You may wonder what happened to the KLH speaker that obviously came with the amp.

	~~[[image:Transducer5~~.~~JPG\|thumb\|right\|Weights Attached]]~~		Unfortunately, this is where the story of the rumble couch takes a turn for the worse and heads for it's end. The friend which I designed this project with continued on against advisement and added the KLH speaker as another tactile transducer. As you may have read above, the sub amp was already running extremely hot. Unfortunately this spelled the end of the amp. After attempting to drive two speakers worth of lead weights, it finally had a meltdown. With a lingering smell of ozone in the air, the rumble couch is no more.

	~~[[image:Transducer6~~.~~JPG\|thumb\|right\|Zoomed Out]]~~		This project was a real learning experience for me. This was one of the first real home brew projects I undertook and it taught me a lot. The initial instructions we read were very light on detail, but it did seem doable. The initial supplies were fairly cheap as we already had the speaker. Once we determined we could assemble the transducer, that's when things got a little expensive as we improvised a way to drive it. If you decide to undertake this project, I hope you have as much fun as I did. Please post in the discussion and let me know how it turns out for you.
