Sonic Electronix review: Unethical behaviour

I purchased a car stereo from SonicElectronix however after I received it decided it was not a good fit for my vehicle. Returned everything in the original packages and was charged a 10 percent restocking fee even thought their website states that there is no restocking fee. When I questioned customer service about this, they claimed the wires were striped for installation which did not happen. Would not recommend this company or purchase from them again.
