Help

I have a sony multichanger, I want it in the boot but am going to remove bits of the interior.

Is this a easy job.

Also i want a cdx m600r They are around 180 quid in the magazines, but 300 in rip off halfords.

I think it will be a good base for my system which will steadily be upgraded.

Where would be best for my multichanger, as it is the size of a brick.
