If you want to install a CD/MP3/VCD/DVD changer you have 2 options (a) get one that can be contrlled by the head unit (that means Alpine). the Alpine CD/MP3 changer will run about 18k and DVD changer will run over 50K. (b) get one that works via a RF modulator usually set at 87.7Mhz or 108.1Mhz. U can get a Necvox DVD/VCD/MP3/CD 10 disc chagner for about 20K.
as far as screens (for VCD and DVD only) go you can get a basic Necvox screen for 6k or a Alpine /Blaupunkt one for close 20K.The Blaupunkt one I have seen allows yu to connect a headphone and also play station!
coax speakers come in 2 types. (a) simple fullrnage cones with a smaller cone called a whizzer attached to the apex of teh cone. they can be quite good if one were to consdier the ones philips made for OPEL in the 90s and hte Fostex fullrange cones. (b) a cone with a tweeter moudle attached to the pole plate through the apex (where the dust cap or phase plug of a woofer would normally be). this type often comes with 2 or more smaller drivers showhorned onto a plastic or metal sub frame. these drivers are more common as their sound is more exciting. Here too there are some excellent sounding speakers most of which I have seen are simple 2 ways (woofer and tweeter). What I see most in India is a Pioneer 6990 with a woofer and 3 "tweeters". the woofer covers almos tthe whole musical range up to 2000-3000hz and the "tweeters" take over from there.
one BIG advantage that these drivers have is that they are usually 2db more sensitive than components. this is because they rarely have a big crossover attached to them the ones I have seen usaually run the woofer without any filter at all and use only 1 capacitor for each "tweeter" they have. WHile this is not such a bad thing per se I prefer to have 2 quality parts than 4 of lesser quality. remember there is no free lunch. Pioneer, Alpine, etc... have to make a profit on each speaker they sell. However now we are delving into audio marketing techniques which should be reserved for another thread or forum.
component speakers are often (but not always) better than coax speakers and are almost always more expensive. They usually require an external amplifier and each speaker system will have a woofer, a tweeter and a crossover in 3 seperate peices. Some larger component systems will have a midrange or misbass too.
an external amplifer does 2 things. (a) It allows for your HU to run cooler since it's internal amplifer is not being used. (b) it allows you to have a really nice amplifer offering better control of your speakers. In the 70s and even as far as the late 80s. most companies did not include an amplifier in their best HUs. You were expected to use an external amplifer. The Nakamichi TD700 or Alpine 7385 were such. My 7385 was bought in 1987 and stll runs well. It has seen 4 cars. When they sold it It came in an exquisite leather case and with a spare head and pinchroller. The Nak 700 is even better built. I dropped one from the 3rd floor and it survived with barely a scratch. |
