i would defo recomment pioneer all the way!!! really good sound quality from there speakers. very clear vocals. iv always used pioneer... running standard speakers in the front in my astra coupe, iv taken the rear mids taken out and iv installed 3way 6x9s instead and a 12inch sub. sub and 6x9s are running through 4 channel amp, with the low notes completley cut out of the 6x9s, so pure clean bass from sub, and clean sharp sounding vocals from the 6x9s. pioneer speakers r pukka. tryed loads of other brands.
