Pioneer TS-A6910 Car Component System

Pros: Warm and deep bass, sound good without an amplifier.
Cons: None.

I have a DACIA car (made in Romania), a Kenwood KDC-519 CD unit and 2 pairs of Pioneer speakers. One is the TS-A6910 which I put in back. I have no amplifier in car, just 4x50 W (22W RMS) from the unit and the sound is very good. Deep and warm bass. At a volume of 25 from a maxim of 35 there is no distorsion. In front I put a Pioneer TS-A1710 pair which is good (not so loud as TS-A6910). I think that maybe it was better if I had bought this model with separate middle from tweeters but it's ok.
