I used to run a K1 without bungs too ya know
@SunGodRA: Heaven forbid I should have an opinion that differs with yours. Like I said, I'm not knocking the work BM did at all as he's done a far tidier install of his setup than I have of mine, and 10/10 for giving it a go. My personal gripe (and it is just a personal view) is that if you're spending £100 on generic fruit-based music player, and then more money on either high quality downloads or music ripped from CD in high quality, it makes sense to have it sounding at least at good as a normal radio station puts out. I'm still running the stock Bose speakers and sub in mine so I can hardly be accused of pimping my ride with awesome sound, but there is a hugely noticeable difference between a tape adaptor and a headunit designed for mp3. The difference is comparable to old mono recordings and modern stereo, and that's just to my ears which I can assure you are not of a proper audiophile.
As long as BM is happy then really that's all that matters. All I'm trying to do is point out the differences in case any one else wants to try this but ends up disappointed with the result, much like I was. Is that acceptable to you?
