I bought a 2003 Disco about 3 weeks ago, the only real issue I have with it is the radio included with the SE model, the "Premium audio system with Alpine® head unit on. Phillips Lear 220-watt audio system with 12 speakers, including amplified subwoofer."
I'm convinced that that phasing of the rear speakers are backwards, or that the amplifier doesn't have enough juice going to it and loses efficiency when the F/R fader is at 0.
The front speakers sound good when the fader is all the way forward. Some nice low-end response.
The rear speakers (and the door mounted sub) sound okay when the fader is all the way to the rear.
But, as soon as I start mixing the front or back, or worse, setting the fader at 0, almost all low-end disappears (I would expect the typical compounding effect of low frequencies), and the overall sound quality becomes somewhat harsh, stereo separation is nil and its just not pleasent to listen to at anything but a whispering volume. Just as one would expect in a system where speaker phasing is out of wack, OR if the DC power to the amplifier was weak.
Has anyone else experienced this with the standard SE audio system? Is it just not as good as I expected, or do you think there's a problem that needs to be serviced? I'm not the complaining type--I'd feel lame taking my rover in to the service guys and telling them the radio sounds "less than stellar", unless this is a known problem, or if I should be getting better results.
