I think the biggest "tip" I can offer is that you just can't expect to install a DSP like the Helix and have your car completely tuned in a few days when you are new to the whole DSP thing. It takes lots of time, patience and research to fully understand how it all works. Lots of trial and error. However, just take it one step at a time. Start with the basics like figuring out how to set your crossovers, your levels, time alignment, EQ, etc... Rome wasn't built in a day. :-) Again, just don't expect to get in the car and be done with the tune right away - it just won't happen. Work on it as you have time and continue to get closer to your goal.
For me, learning to EQ is the hardest part and takes the longest to figure out. Even when you realize how to actually EQ, then you still have to learn exactly what type of EQ "curve" really works for you. For me, that was probably the hardest part. I just wasn't happy with the results after tunning to any of the "pre-defined" house curves - I had to really spend some time figuring out my own EQ curve. Just knowing what freqs to adjust to reach the overall sound you are looking for was not easy - but you'll eventually figure it all out. Again, just takes time.
Another thing I found very helpful was Room EQ wizard. To me, learning how to use that software for EQ is huge. Being able to take your measurements and then using REW to adjust the response and see the "predicted" result was a huge help. I would take measurements and then just work on them in the house, fine tuning my curve - that way I wasn't spending hours out in the car. I'd get things where I think I wanted them in the comfort of my home and then take the tune out to the car, load it up and listen. Maybe make a few manual adjustments while sitting in the car - then take new measurements and analyze them in the house on my PC when I had time. Rinse and repeat. That is just the way that *I* found works best for *me*.
Lots of knowledgeable people here to help along the way. It's a very rewarding experience. I've learned so much about audio while tuning my car. :-)
