Hello, dear people As a “Rudi-No-No-Knower” I venture here an entry to get opinions or advice from you. In my new car (panda 100 hp) I would like to have a car-hifi-system of the brand “Alpine”. This should consist of the following components: CD/Radio Alpine, CDA-9852 RB (or CDA 9812 RR) CD-Changer Alpine, CHA-634 (6 CD/MP3/Ai-Net) Amplifier Alpine, MRP-F450 (4×70 Watt, 4 Ohm) Boxes (4 Stk) Alpine, SPS-17C2 (2-way coaxial loudspeaker) 50 watts rated power , max. power 250 Watt Alpine, SPS-171A (2-way components) 50 Watt rated power, max. power 250 Watt) My questions: 1. Do the parts fit together? 2. Are there (better) alternatives from Alpine? 3. Does anyone have experience regarding the sound characteristics of the boxes (very good, good, medium, modest)? 4. Would you add a subwoofer in addition? 5. General remarks about this “concept” of you? My budget for the individual components total Euro 1’300.00 (excl. Thank you very much for your vote.
