This is a very simple system consisting of the minimum components needed To keep the weight down, it has just one amp, a pair of tweeters,
a pair of Midrange Speakers and just one Subwoofer, all controlled by the Head Unit
However for the competition we did use an Electronic Crossover for tuning purposes
I'm glad to report that after we took it out it sounds even better...
Every installation was made to be easily removed in case the car has to be sold.
