After trying a few different sets of car speakers (each around the £70 mark) and being dissapointed I finnally decided to take the risk and purchase these high end alpine speakers.
After reading all of the information i could find i decided that these would suit my needs well, im used to high quality Bose systems at home so thought these could produce similar results in my car.
When i got them out of the box my first impressions were of how well they appeared to be made, the cast aluminium frame and the multi-role surround on the cone gave an immediate impression of the quality. The included crossovers also carried on this quality feel.
Installing them in my car was simple, remove the old speakers and fit the woofers, then find a suitable place for the crossover and route the cabling for the tweeters to the dash board where i chose to place them. Two more cables running to an amplifier (Alpine MRV-F345) in the boot and it was sorted.
A card was included to help you set up the crossover to achieve the optimum sound from the speakers. This gave simple instructions on measurements to take, and then showed the corresponding jumper settings on the crossover.
Once connected to the amplifier it was time to turn them on and i wasnt dissapointed. They obviously don't kick out lots of bass as they're only 13cm woofers but the quality was fantastic. All vocals were clear and full, and the midrange respones of the speakers were equally good. There was no distortion at higher volumes (within reason of course) and good cope with a wide range of music.

All in all i was very pleased with these speakers, although expensive (rrp £250, i got them for £150) i feel they were worth every penny and coupled with a decent amp and subwoofer reproduce music very well.
