I Pulled the trigger and purchased some Polk Momo 5x7's (fronts only) and an entry level Kenwood HU for my 2002 Tacoma- both for $205. :D I can't believe the great prices they have at millionBuy.com
I auditioned the db 5x7 at Circuit City and was only mildly impressed. They don't carry momo's so I'm buying them without auditioning them first. I'm hoping to avoid getting a sub and amp, but will consider it if the momo's needs more power or if the lows don't cut it.
I found a local car auto shop that will install the speakers for $30 and deck for $30 + installation parts.
Can't wait to hear how it all sounds,
