Got bored and have lots of wood to work with so figured i'd make a box for the big bear, 4 - 6.5' boss marines and a ssl200 amp no headunit, goin to upgrade the speakers soon to crescendo 6.5" cause there louder and nicer heres what i got so far 

 

This is the amp i will be using, a ssl 200 watt 

 

Got the fleece stapled down but it's too rainy and humid to do resin today 

 

Finally got it done, turned out pretty decent 

 

 

Once I get my box done for my Jimmy I have a similar project for the wife's Rancher.  Four 6.5" Bravox marine speakers powered by a Clarion marine stereo with Bluetooth capability so her phone never has to leave the safety of the watertight compartment on the quad.  I'll be using left over materials from the build in the Jimmy, sealing it with resin and covering it with Bedliner.

 

 

Yours turned out pretty sweet looking.
