Nice addition of power to stock speakers.
Great price.
Clarity in sound efficiency coming from speakers.

Not sure, however, I would not use this if I were building a high-end competition setup.

If you are not looking for a high-end stereo system, this will work perfectly. I have another car with after market receiver, amps, woofers, and equalizers, but this is not the same. I would not consider this a competition booster/equalizer. If you are looking for an inexpensive way to get a boost in speaker performance and clarity with stock or after market receiver, this equalizer is the perfect solution.

None...other experiences dealt with higher end systems.
