Right, alpine headunit in, now time to sort speakers. I am after a money, more or less, no object solution to get the best sound i can possibly get from upgrading speakers, only thing is that i want everything to look stock so no custom builds. i am looking at the alpine x- series reference or pro components for front and possibly rear parcel shelf as it is a saloon without bose. questions: a) will they fit (i've heard front doors have around 55mm depth allowance) b) are there better speakers that will fit c) what sort of amps should i be looking at powering 4 component speakers (i'm well out of touch when it comes to ICE) d) anyone recommend what sort of speaker cable to use. as for powering amps, i was going to run a 0 gauge cable to the boot and put a distribution block in there, obviously fused at the battery and again after the disto block. is this sufficient for amps? is rear parcel shelf strong enough to take the weight of a 4 channel amp? after my rear window blowing out a couple of days ago after the sealent went, i'm a bit nervous about the parcel shelf and adding loads of weight on it when the window is bonded to it. (probably me being stupid i know) for info i will be getting possibly a 12 inch boxed sub in the boot later, any recomendation? i listen to mainly dance music as this will be a consideration i guess.
