check voltage on the amp with a multimeter. I bet voltage is dropping when the amp is going down.
Could be a bad connection, but most probably it's the fuse up front.
If you're using a glass fuse, just change to ANL, way better.

I want the led taillights.
As I'm from the netherlands an wel known to Milo , it's probably a good idea to send it all to one adress so we can split the delivery costs.
Just gimme a PM off the total costs (seats+lights+shipping) and I'll kick milo in the butt about it...
The corsa B shocks have a better fitment. The bolt holes have a better line up than the polo ones. So you need less modding.
Also, I think the corsa fronts give the k10 better handling than the polo ones. Polo ones can get you lower (about 1 inch I think)
I've tried both on my first K10.
Gonna...
A polo is actually a little bit heavier...
Anyway, you can use the polo 6n rear adjustable collies on the k10. At the front polo collies are also used, but I prefer Corsa B at the front.
