MB/C300/Sport

I have a 2008 C300 Sport with the Harman/Kardon LOGIC7 system. I have a front drivers side speaker out, and my question is are the Infinity Kappa 60.9cs for the front an upgrade to the OEM Harman/Kardon speakers.

I would opt for the Focal ones.....I upgraded mine...but I also added a Audison Bit 10 processor and Digital Alpine 4 channel amp.

what focal speakers are you referring to for the front and back.

I used the Focal 165 V30's for the fronts....and the Focal PC165's for the rear doors.

Great sound......powered by an Alpine PDX-F4.....4 channel 400 watt amp.

Everything looks stock.......but the sound is amazing.

Though my speakers are still fine, I'll soon be replacing the fronts with Focals 165 KRX2. Rears are Boston Acoustics Pro60 SE which are fine, I paid more for them from Crutchfield then, than their current price; I may change to Focals 165 KRX2. For an amp I use
Rockford Fosgate T600-4.

Also...paired it with a set of 10 inch Alpine Type R subs..running off a JL-500/1 amp...and a ported box......that looks stock in my trunk.

Very nice, I like the way your trunk looks, clean.
