INSANE LOUD,Playing music dubbed around 35 hz. shaking windows at Sinister Autosports shop

Still the 4 Hcca 15s and I Changed out highs amps to a JL audio vs 3 others. Setting in front of Sinister Autosports we were playing with the sound and couldnt help but notice their windows were shaking from the bass. Inside the store pictures were shaking and the door rattling. There is only 1 way to appreciate this machine..... Get in and listen. Every car show that I go I use this for hands on play time. It is a toy! If you see me and want to hear it... I never say no. There has been some controversary
