At long last I have finished installing my Sat Nav and rear speakers and amplifier. I even managed to wire my hands-free phone kit into the radio, so that the radio automatically mutes and the phone call is heard through the front speakers:bannana: . Much better than the tinny Nokia speaker. Sat Nav is brilliant, it makes driving so much easier and more relaxing when you are in unknown territory. I couldn't fit 6x9's in the tailgate so went for 61/2" full range speakers. New Infinity speakers for the tailgate and a Vibe amplifier to power them. The install all looks very good and everything was done properly. The only thing I am not 100% happy with is the position of the amp, I would have preferred to hide it out of sight and out of the way, especially when the dogs are in it......well that's why I have an estate!!! I may consider 'hiding' it inside the spare wheel well but am not sure if there would be enough ventilation. Oh by the way, the sound improvement is excellent, at least 10 times better than before. The amp can be turned up so that you feel like you are being punched in the back. Or just set so that you get a nice all round sound.
