Audio, hi-fi and car audio - Emerson speakers - opinions + Install recommendations REQ.

Hi all, I've been looking to upgrade my motors factory fit speakers and
came across these.
http://www.autotoys.com/x/cust/produ...&cat=75&page=1.
I
intended on spending much more on replacements than the cost of these and
I'd never heard of Emerson before so I'm hesitant. But they do seem very
well speced and very well priced, as did many of their products I found
c/o
google, but no reviews were to be seen. Past experience has taught me to
stay clear of cheap speakers but at the price I'm tempted. - Has anybody
had
any experience with Emerson? Good or bad, I'd like to know.

If you checked the link then you probably guessed I own a Ford - a Focus
to
be precise. I all ready have a sub/amp and a decent spec HU installed but
I'm no audiophile, so I'm not too worried about switching to smaller
drivers
unless the mid bass loss was going be catastrophic. Should I forget about
these and go down the 6x8's (or 6x9's) route? Though bear in mind that the
replacement speakers will be powered from the HU(4x55w). Like I said, I'm
no audiophile. I'm just looking to improve on stock.
Opinions/suggestions
welcome.

TIA.
