Got my amp and sub put in this week. Alpine MRV-F540 and a CDT CL1015 (tuned to 30 Hz). Very impressed with the job done. My system now does exactly what I want it to do and sounds awesome with acoustic and jazz, especially female vocals. Modern pop is dealt with very well also. Takes up hardly any boot space either (~1 cubic foot).

At first it sounded terrible and really made my left ear hurt, even at low volume. We discoverd that the front channel RCA's were the wrong way round at the head unit. Swapped them over at the amp (easier) and the difference was night and day.

I also got an ipod and use a Belkin car charger which has a line out. This is plugged into the auxillary input at the back of the amp and I'm very impressed with the sound. I did rip most of my CD's at 192 and some at 256 though. (Note: no more CD's taking up space in the car)

I would like to move the charger away from the ciggy lighter. Ideally it would be completely behind the dash so there is only one wire coming out which plugs into the ipod. Is this easy to do? I was thinking it would be simplest to install a second 12v socket behind the dash and just plug the charger into it instead of ripping the charger apart and stuffing up it's internals. Anybody else done this?

I'd avoid using the lighter socket, why not just cut the plug off and hard wire the power under the dash. Much more secure and you can always re-attach the lighter plug later if required.

I got one of the belkin car chargers they're good but i wish they had a line out instead of a volume control... I'm looking into overriding the volume control but its a bit dicky... anyway. yeah splice into your ciggy lighter and wire it up that way. Then you can just have the one wire coming out mine goes through my ashtray and I have my ipod mount coming out on a flexible bracket. Very easy to use and solid as a rock. Sits just above my gear knob. Can also use both cup holders still.
