We installed Steve's system last night in the fairing. The mmats 4110 amp and 601CX is hard to beat for a budget friendly setup. Our plan of having HU flashed to 8/2 at a local shop and running speaker level inputs into the DD DSI-2 worked well. Sounds super clean and has plenty of volume. Didn't have time to do much tuning last night other than setting crossovers to keep the speakers nice and safe. I'll let Steve give his first impressions, but I think once those speakers break in, they're gonna be even better. We will do some tuning in the near future and get that fairing dialed in.
