Alright, I'm glad everyone has had a good laugh at my expense :D ........ (it was deserved).

Obviously sebastiantombs and garycrist are correct. My misunderstanding comes from the fact that audio manufactures typically post their power consumption figures at 1/8th of the max power usage and not 100% power usage. This means the power specs on their websites don't match the "max wattage" rating of their equipment which resulted in my misunderstanding. They do this because the industry has decided that 1/8th power is an accurate representation of what an average amplifier is going use in power in an average situation. Obviously actual power draw will depend on the overall voltage which increases with loudness, but a speaker is never going to draw 100% power all the time - at least not for very long ;). The manufactures 1/8th power usage specs are pretty accurate and can be used to determine normal power consumption in a typical use setting. In a use case like the OP is suggesting, the power consumption would be well below the manufactures 1/8th specs. This is also why you will really never need 10amps to drive a 100watt 12volt speaker because you will never actually drive the speaker that hard even though Ohms law says that is the power needed.

Hi gents,

Just checking in to say "hi" and use my login credentials. Great to see everybody is still active and hangin' in here. I've been MIA for a while since my system has been dialed and performing flawlessly for the most part. Alas, I've re-immersed myself into my vintage VW hobby and have been working on my '65 Beetle for much of this time.

The asshole is still trolling in front of my house in the wee hours of the night. On about 10/14 he scattered a bunch more of his Jack in the Box fast-food trash in front, so I decided game-on: I scooped it all up in a bag and the next night brought it all back to his house in his quaint, well-manicured neighborhood on the posh side of town and scattered it across the front of his property. It was extremely exhilarating and satisfying. My message to him is, "Any shit you bring to my house, goin' right back to your house."

Then, as part of the plan, about two weeks afterward, mailed him screenshots of my footage with him dumping trash in front of my house over the last 11 months, along with an image of the police report incident card. Basically he's on notice that we know WHO he is and WHERE he is. Surprisingly, he's been back by two more times since, which is in the past week. Perhaps he wanted to get a look at the cameras and see how in the hell I caught him and figured out who he is. In any case, I'm expecting this is a forever-problem and I'll be dealing with him until he croaks.

Cheers, and thanks again for all the support in building up my system!

@Steve.L Do you know why he started dropping trash at your house? Did you have a run-in with him before his first visit to your property?

Side note, for some reason YouTube has been suggesting a ton of these videos on my account:

2 Approaches I can see:

1. Look at environmental laws for fly tipping and see if your City will take action

2. Get an Injunction keeping him from coming with X yards of your property. If he breaches one he could face arrest and jail.

3. Get a gun and learn how to use it. Not to shoot him (!!!!) but for self defence in case he goes crazy after 1 and 2 and attacks you or your house, depending on your local laws.
