Help! I have mounted my subwoofer amplifier underneith the passenger seat of my 04 AC. I am new to this and figured i could mount the amp strait to the foor with sheet metal screws. When i went to test it the amp turned on, and worked fine the next few days. Then it started to rain here and ever since the amp will turn off randomly while im driving. The four mounting screws stick out of the underside of the floor and i was wondering if the wet metal could cause a short circuit. Please Any Advice?
