I just had windows tinted and i noticed the subwoofer didnt have as much base (bass) anymore.

On regular setting, 0 or 1, it used to have good bass, now it sounds week. Could tint installer have had water in there while installng tint?

or subwoofer or amp defect?
thanks

I would check out the actual subwoofer speaker. I had my windows tinted on my old car and my ezpass stopped working right after. Maybe he did get water in it but it would have to be a lot of water to damage the woofer. remove it and see.
