Annoying sounds from cars at stop light

Not if setup properly to play below the main speakers, and at the right db level. Also car Sub system designs trump home audio subs in that the amps are isolated, and not placed inside a rattling box. Cracks me up whenever I hear about XX brand Sub home owner, whose sub just went down because of a circuit board solder break from the vibrations and heat, and the manufacturer only recommends replace with new.

This is another reason proper Sub/s location - placement - is so important in a home setup, so the sub/s are not overworked.

You realize that many of these kids are the future of "audiophilia" and stand to inherit our toobs, vinyl, and stuff that actually sounds good, right?

The only thing my son has shown a "real" interest in is what "it" does, and resale value. The Conversation is always the same.

He pays a visit when I am listening.

Son - Hey Dad, what is this, and what's it for ?

Dad - Son, that is a XXXX, and it does XXXX. 

Son - so what is it worth dad ?

Dad - Son, it is worth XXXX on the market.

Dad - oh, and don't tell your mother the last part.... keep it between us.
