This Viper sounds great. After doing installs in several Viper convertibles I will say that this one sounds the best of all that I've heard. We did experiment with the subs quite a bit, and Kyle was very patient with us as we tried to do the impossible (make a sub between the seats sound as good as a sub in the footwell), and while we couldn't do the impossible we did end up with a LOUD and CLEAN sounding system that stays very articulate and punchy even with the top down and the loud side pipes.
I'd say that a Viper convertible is possibly the worst/hardest environment to get a great sounding stereo in, because it's a loud car, it's ******* and it has absolutely no room anywhere to put components. I'm very happy with the way this one turned out.
As he said, the center sub was a lot of effort for not much "subwoofer" punch but with the 5 channel amp running the 2-ohm components high pass, the 8" center sub as a midbass driver, and the 8W3 as a pure subwoofer, after some tweaking crossover points and gains on the different speakers it ended up sounding better than you can get with just door speakers and a sub. That 8" midbass really fills out the sound, especially with rock music at high volumes.
Great sound in a great looking, and unique/rare color beautiful car.
