Tony, I understand all this. It's already been made quite clear to me. That other joker was simply putting it to me that I'm wrong for thinking I can replace my head unit with an empeg, get new speakers and an amp, and not have a sub.
I don't subscribe to that perception about subwoofers. Hell, I have one on my computer speakers and it sounds great. I'll never have to pump the audio through the entertainment center for my tunes to sound good.
If the speakers alone can do a good enough job for my ears, then that is all that matters. Because it's my car. I would simply like to avoid having to put one in the car if I can. But I haven't ruled it out.
