That's a common misperception. Yes, it will punch harder with a lower resistance, but to find an amp that is ACTUALLY stable at 1 ohm is almost impossible. It heats up so much that it will cook the amp. Home stereo gear that could drive at 1 ohm will cost at least 5 digits, probably more.

Besides, you are talking about your amp running at around 1,000 watts at 2 ohms if it claims to be able to output 1800 at 1 ohm. At that kind of power, you are looking at having to replace your alternator AND throw in a capacitor to store the power for it. What model amp is it, and what types of speakers exactly are you looking at installing? If you give me specifics, I can answer your question better.

And where in maryland do you live? I live in Annapolis, just an item of curiousity.
