[V8] speakers/deck question, aftermarket

[7013885254]

So now that I'm near done redoing the interior,  I think ill do the stereo too.  I just  wanted to ensure we have a pair of 3.5in ,4in , and 6 by9 in speakers,  right?  As well there was a company who made sharp almost OE looking decks that was discussed on the list I forgot the name too, anyobe remember it?

After that just need a 6 channel amp and I'm good...

Ty!
