I was able to get my Helix DSP tuned from Honza at Soundtech. After following Soundtech of Facebook, and seeing others who have had great things to say about a professionally tuned system I felt I should finally get it done. I was pleased that I could be booked in within a few weeks and at a time that worked for me. To say I’m pleased with the results is an understatement. It now sounds great. The mid-bass is a lot more punchy, the small 8″ sub sounds bigger than it is. The highs are now not going to rip my ears off and it’s fair to say that I love listening to music in this car now. I would recommend Soundtech to anyone who is looking for something more from their car stereos. Mine is not a stock system, and the front speakers are in the higher range and now they sound like money well spent.
