Amplifier Box (Small 12v Amp)

thingiverse

EDIT: 4/28/16 FINAL Change I hope, Added glass fuse couldn't find a panel mounted fuse I liked for a blade (couldn't find one locally either) so I bought one from RadioShack. I also added a strain relief with a lock so wires can't be pulled out. Widened the case some to give more room. Stereo in stereo out dual phono/RCA plugs. There will be a couple different versions in the future. Changes like without pot and fuse etc. As the title states, a box for a small amplifier. I put in a Pioneer AVIC 5100NEX in my 04 Ram, along with headrest monitors for my 4-year-old. Once the install was complete, I had no sound out of the headrest monitors, or so I thought. Engine off volume down low, I can faintly hear the volume from the headrest monitor or headphones. It appears my head unit puts out a certain volume and it's up to the headrest to have an amplifier to well amplify it. Apparently the ones I chose are cheap and don't have it, so I purchased this amplifier from my contact over in China (I do a lot of business with them), and made this case. This will be plug-and-play when done. I made a few versions of this and I think this one is by far the best. I made a duct to help force air over the heatsink. I know for what this is and how many watts it is (50 watts) that the heatsink shouldn't get hot, however just as an added precaution I added the fan. Plus who likes hot electronics? Revisions to be made, and will come once my taper pot gets here. Add hole and tick marks for taper pot (adjust the volume of the amplifier) Post-printing You will need the following: 4x m2.5 x 5 4x m3 x 6 1x RadioShack LED Green (built-in resistor) PART# 276-0085 1x Amplifier board found here: http://www.ebay.com/itm/162006712978?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT 1x 10k stereo taper pot 4x Panel Mount RCA/phono jacks (from Ebay link soon) 1x Philmore 65-1020 Strain Relief with wire lock 1x RadioShack panel-mounted glass fuse holder 1 1/4 x 1/4 PART# 270-0364 1x 20 amp fuse (RadioShack) Part NTE#2701074 And a knob if your pot doesn't include one, or just print one.
