Cheers Technic. Thanks for the explanation. I had a long chat with Patryk and while the BimmerTech option is more than I budgeted, I'll most likely go for this but I'll have to wait a little longer as there are some heavy bills coming my way in the next few weeks....a wedding and all that jazz
I don't think the other half will appreciate me splashing out on this when other things have to be paid.
Nevertheless, I'll keep an eye out for any deals and hopefully pick up an amp by September.
