Below is a video of my Helix HX-4700. It has taken me almost 3 1/2 months to complete this build and close to 50 hours

The modifications to this radio are extensive, with custom made PC Boards to hold the LED's, resistors, fuses, switching and more.
The clock features 24 hour time setting, volt meter / battery gauge and a temperature sensor that is mounted in the bottom of the radio giving the outside temp.
The Bluetooth module can be unplugged and a 1/8 to 1/8 plug wire can be used to tether any MP3 player.
The glowing speaker surrounds have their own power supply and is held in place with Velcro. It has a power switch and sensitivity adjustment.
The factory alarm system was upgraded with a flashing LED light.
The factory tweeters and midrange speakers were upgraded. The woofers are stock.
The decks have been re-belted and are fully functional as is the tuner.
The entire stereo was stripped down, all the electronics were cleaned and repaired as needed.
Speaker grills straightened and repainted semi-gloss black.
The handle was reworked along with the case to eliminate rattles and squeaks.
I will post more pictures and info on this extensive build when I get more time.
