Why fit components to the rear? You don't need them, Micra's are not big enough to need rear fill audio.
You'd be better off using the amp to drive the components up front and a sub in the rear.

Have bought loads of kit from them over the years without any issue and have been good when I've had to return items.
May not be the cheapest but I think they're pretty good when it comes to customer service.
You always get what you pay for with them! (Y)...
Winter Tyres are great for the colder weather, you'll notice a slight difference in grip when it warms up again.
But from 7degress C down they offer a lot more grip. You'll probably find them noisier than your summer tyres.
Personally I'd stick with Pioneer or Alpine. I use a Pioneer AVH Double Din in the Avensis. Might be worth also looking at JVC as I've had a number of fantastic units from them which were really underated.
Cool, nice to see there are some new NE members. Think the meet may have to be next year as I'm tied up with too many things at present. Unless someone else fancies a go?
It's not crime that drives the cost up, it's the number of claims in the area on the whole.
That's why one street can be cheaper than another, as one may have no drivers who claimed whilst another may be full of people who've claimed.
