Well, I auditioned quite a lot of speakers before zeroing on the Focal & Auditors. To begin with I auditioned JBL, Hertz & Sony. JBL were the best amongst the three, Only grouse being, they were loud with good Boom but were not good for the high end frequencies, I felt missing quite a bit vocals with just the boom there. Hertz give you high end frequencies but were missing the boom effect. Sony were well quite worse amongst all the three. The next stop was the Bluapunkt Dealer. He showed me the THa series and Velocity series. THa were really good, but then at the same price you can get better brands so opted out of the THa Series. I liked the Blaupunkt Pnp Amps, very easy to install with just two specific cables needed. I did audition MTX and Rockford Fosgate, but Rockford Fosgate, JL Audio & MTX were pretty much out of my budget. In all these Focal made the most sense. I spend about a month and half to finaly decide on the Components I want to go with. This was one of the factors that wanted me to change the speakers and then I thought of doing the complete upgrade. IMHO the Head unit is sufficiently capable of driving good speakers. If I may suggest, its better you decide how on your budget and what is it you are looking from the ICE setup before taking the task to get an upgrade done. The first step can be just replacing the factory fitted ones with a good pair of speakers. Later on you can think of the Sub and Amp, if you want to go whole 9 yards.
