Quadratec Soundbar Acoustic Upgrade Kit for 07-14 Jeep Wrangler JK

Get the most out of your sound system. This Soundbar Acoustic Upgrade Kit corrects the back wave distortion which means purer sound. The acoustic pad incorporates micro-cellular technology with a peel and stick application and guaranteed adhesion. Rear wave and standing wave distortion occurs when speaker sound waves exit the back of the speaker and reflect off the plastic surface of the sound bar. The sound waves that reflect back towards the speaker then mix with the waves that are moving forward from the speaker. This creates distortion, and interferes with the clear, natural sound that you hear.
