Finally booked my car in at Cambridge Car Audio to have my empeg fitted. They're quoting around 2 hours, and it's quite a simple installation.

They're just putting a 2-channel amp under the passenger seat and connecting it to the stock door speakers.

Later in the year, once I can afford it, I'll get a sub, replace the door speakers, and upgrade to a Kicker 4-channel amp so I can drive the rears as well.

No rears, no sub -- not sure how I'll cope. Still, it'll be better than listening to Cambridge radio stations.
