I love my stock in my new sxt and my 96 has a mp3 player and 3 way pioneer front and rear speakers.

 

Pioneer DEH-360 head unit.
Pioneer tweeters in the dash.
Pioneer 3 way 6 1/4" speakers in the door panels.
Pioneer 4 way 6 x 9's in the rear deck.
12" Kenwood sun in the trunk,

All powered by an 800 watt Kenwood 5 channel amp.

 

I'm stock for now....I'll probably add some new speakers at some point along with some a sub or two...but for now its good enough for me.

 

Mine is stock except for the head unit, an Alpine CDA-7863.

 

my head unit is a kenwood mp3 player
6 1/2" pioneer speakers in the front and 6x9" pioneers in the back
not sure if i want 2 10's or 12's so no subs til i figure that out

 

Alpine head unit. stock speakers and 1 10" RockFord Fosgate sub wolfer, powered by DHL amp. Well I think that is the amp, I would have to look again, I know it is 3 letter and starts with D.

 

pioneer 6400 head unit
hifonics brutus 1500d amp (1500 watts)
and the subs change every week
anywhere from 1-4 mtx thunder 8000 12's
resonant engineering HC 12's
kicker l7 12's

im never satisfied with the bass im getting so im always buying and trading for new subs that i havent heard yet.
