Its a 2 way 6.5 inch component speaker system and I would like to fit it into the slot of the existing car speakers ( all 4 of them ). I would prefer a plug and play fitment. I could not understand the the speaker picture ( imean, is it that it is a speaker with the tweeter inbuilt or have they got external tweeters which have to be kept hanging or have to be fitted on the dashboard/under the dashboard somewhere) ?
