This is a review of the Pioneer GM 6300F, I bought this amp for my Alfa 159 after purchasing an in car amp for my brother, hearing the sound put out by his amp I was instantly jelous and decided to bite the bullet and Purchase this Pionner car amp. This is alot easier to set up than the main rivals. It comes with a simple instruction manual and the needed cables etc. It can be fed in to two speakers at 150 wats RMS (300 watts max) or in to four speakers at 60 watts RMS (120 watt max). I opted to plug this in to two seperate speakers as my car alreadt boasts an 8 speaker system. The sound out of this is unreal, the quality is unmatched and I have to say I preffer this model to my brothers (Sony, see my review!). I do tend to opt for Pioneer when it comes to in car systems but I that is simple because in the past they have never let me down. All in all this a great buy.
