thats the reason i dint suggest Vtrek earlier.
no i am not only talking about Vtrek but any brand,i havent seen any compo in kolkata yet.
Tell me something - are you going for compos, just for the sake of it, that is, to show off, like your sub? or do you actually want to good quality music?
not only for spl but sq also.
if its just for show off, better buy a 6" round speakers (Rs. 2000-2500) & add a pair of tweeters to it (any brand, Rs. 500). this is the cheapest option. of course, there wont be any crossover & so you want have quality sound, but yes, your car will have a tweeter.
i have 5'' ultimate speaker they are not good and i think again buying a simple 6'' round speaker is not a good idea or upgrade.another reason is sound stage, right now its very poor in my car.i am 100% on driving seat,so a compo will help me,correct me if i am wrong.
if you are looking for quality sound, dont bother buying the sony comps. the RMS is just 60W & sensitivity is just 88 db/w/m. add Rs. 1000-1500 more & buy JBL comps.
the 608C will cost you around Rs. 4500. the RMS in JBL is 70W & sensitivity is 92 db/w/m. mind you, i mentioned this since you are interested in specs, i am hardly bothered!
