Hey everyone. I just wanted to share my version of the popular Boomcase. I didn't want to drop over 500 dollars for one so I made my own. Materials cost me about 50 bucks, and labor was two weeks, mainly waiting for parts to arrive. Majority of the items are reused from a thrift store or I harnessed it from old electronics. It's still a work in progress since I am still working up a way to add a battery and charging option to it. Happy Viewing!!!

Step 2: Step1
-Figure out what your desired speaker configuration should be.
-Do a mockup in a cardboard box, mine was from a item i just ordered that week.
Step 3: Step2
-Tape up your suitcase, draw your template
-Drill starting holes, and cut into the box, a router would be ideal but I only had a stainless steel kitchen knife from one of those infomercials my mom got me, I never had the need to cut through a frozen turkey or bricks with it.
-Dremel your holes smooth and to fit the speakers.
Step 4: Step3
-Drill holes to fit amp, dc jack and 3.5mm jack.
-Fit everything and wire it all up, tape it all up, your DC plug and 3.5mm, use the volt meter to find the positive and negative of the DC plug, usually striped wiring or red is positive.
-hot glue everything to case.
-Note: the amp has only 2 outputs at 8 ohms each, if you want to add tweeters you would need crossovers or component speakers that have built in crossovers which mine did.
Step 5: Step5
-Close it up, plug it up and enjoy
Step 6: Battery
For now I'm using my portable 10,000 mah Anker battery that I use for charging any 5v usb or 9v/12v dc electronics on the go. It can power the case for over 10 hours at the volume and amp draw I play it at. And when not in use i pull the bat out and use it for my cellphones, cames in handy during hurricanes like Sandy.
