We've seen custom Cadillac trucks before but none that look and sound like this flat black loudmouth. The wall of MTX Audio subwoofers is definitely a sight to see and the decibel waves that flow out when the '04 EXT's doors are open are downright deafening. Can you believe that the Caddy was completed in only five weeks? Amazing, right? Well, considering that MTX unleashed its own group of talented installers on the half truck, half SUV show stopper, the feat seems a bit more believable. With a quick glance at the EXT's mostly matte paint scheme and the arsenal of audio components that has been loaded into its cabin, you may be asking yourself why anyone would gut a perfectly good luxury vehicle. The answer is rather simple if you think about it. "Shut up and listen" seems to be the direct statement that is being conveyed through this well-to-do hauler's subdued exterior and vocal aggression. Lucky audio fans have had the opportunity to hear MTX's EXT in person as it made its debut at the '08 Consumer Electronics Show earlier this year and has been on the road attending various events ever since.

You may be wondering just how aggressive the Cadillac's battle cry really is. Well, the crazy fiberglass enclosure located where the back seats once resided houses eighteen, count them, eighteen 12-inch MTX Thunder Square subwoofers. With bass like that, it is quite possible that an eardrum or two has been burst during the EXT's tour across the country. The system's total power was recorded at an astounding 7,500 watts at 2 ohms, which is gained through the bi-amplification of an MTX TE1004 amplifier at a 2 ohm load to match the 2 ohm rating for the three TE4001 amps running the subwoofers. For those who get confused rather easily when it comes to audio power ratings, just know that this Caddy has enough juice to rattle you stupid, at least while its sound waves are directly reverberating through your cranial matter. It is absolutely wild to think that so much sound can come from such a relatively small space but that's the name of the game in the world of mobile audio.
