Hi Rockhopper

When I had my RF amp I had come from one of the early Alpine V12 so it was a fair step up. Having said that when I had the Alpine and the speakers in the door I often thought it was running out of puff. When I then moved the speakers to dedicated footwell builds, it never seemed to happen. I think because the footwell builds were a much better location for the speakers and a lot less of the energy was being tansferred to the door panel, meaning that perhaps there was less destructive interference. A bit like making stiff speakers cabinets. That in turn gave the amp more of a chance with handling the sub, so much so that I had to tweak the crossovers to get the balance right again. Boston Acoustics stuff is good kit though but isn't it quite demanding, electrically?

Paul, I think this highlights a good point, which is that the quality of the installation of the car hi-fi is very important because there are some many variables, road noise, panels, speaker location etc. I would rather have a good install with mid-priced kit, than high end kit poorly installed. A good dealer should help here, but since I was last buying stuff they all seemed to have disappeared, probably due to internet price competition..?

Cheers
