4) New Boss R53 5.25" 400W 3 Way Car Audio Coaxial Stereo Speakers 2 PAIRS Chaos
Replaced some very old speakers so by comparison it is a no brainer.  These speakers sound great for $40 some bucks.  Only issue is I did not look closely at the grill.  It leaves an opening to the speaker cone.  This could easily get punctured.  They should have just made a solid cover.
