I'll have to get some new pics added, I've changed my setup a bit.  The radio pictured ended up crapping the bed on me, it had been sitting on a shelf for ten years so I'm not too surprised.  Went with the Cobra 29 LX, same as pictured by OP.  What I wanted to show you guys is the PA I added under the hood.  Ran the wire in the same fashion as the power to the radio, just up the other side of the windshield.  I found one, tiny open spot in the engine compartment that was almost made for the speaker.  Even had an open, threaded hole in a nearby bracket that I was able to mount to.  I sent my radio off for a peak and tune, once I get it back I'll try to post some pics.....or, maybe I'll just get a pic of the PA and post later today.  Anyway, stay frosty!
