All three of the solutions you mentioned are going to sound like garbage if you don't add more $$. For starters a good amp and some decent speakers - consider a sub as well. I'd say that's a MINIMUM of an additional $1000-3000.

I don't know anyone with the same level of SQ as my install. My empeg install.

I also don't know where you'd get an Alpine or Pioneer system, INCLUDING NAV, for $1400 complete new. Unless they have some new models I haven't looked at priced at half what the previous models were.

Whatever decision you make, just make SOME decision and stop posting such lame threads. Really, they're ANNOYING.

You ask for help comparing Apples and Oranges and come up with the most contrived systems with completely off-base prices. Why don't you just install all three of them? If price doesn't matter...
