I own a 2015 Porsche Macan. I ordered it back in June 2014 when the model first came out and had to wait 6 months to pick it up... 92K miles later, I still have it, and I enjoy it very much... Never had a car for so long. Up until now, I have tolerated the Bose system that this SUV have...

that you have owned, what is it and why? not interested in "they all the sound the same or a watt is a watt", best amp you have owned

And I need caught up please. In that time, I took my home system from a huge expense system, to a simple server based system with DIY amplifiers. Huge downsizing. I've heard rumors, but am interested in if head units now have FULL dsp? Are amplifiers still the footprint of a shoebox for quality...

SD-4 Series - Sundown Audio Yard Sale (sundownyardsale.com) Some of you know I think these are pretty sweet shallow mount subs. Better than the equivalent JL model.

I'm looking for a 4 channel amp to power some component speakers for my front stage. i can buy an Alpine PDX F6 for $300.00. Is that a good deal or should i look for something else that's around that price range. Any input appreciated.
