Check your amp grounds. Both symptoms you describe are common to bad grounds. Congrats on your wedding.

Good ground-- A floorboard completely scraped of its paint...only bare metal is present
Also, the wire should be tightly crimped into a ring terminal, and the ring termial should be bolted securely to the paint free floorboard...
You shouldn't use a seatbelt bracket or seat bracket as a ground, and grounds shouldn't be shared, or near other grounds ((from vehicle lights or things) i.e. the ground should be isolated from other grounds and should have it's own retaining bolt)
