So I did email him last night after playing around with the system. As mentioned my bike is stored for winter, so as he was installing the system and setting it, tuning it, etc... and while I was playing around with it, the bike was never running. He responded to me and asked me to make sure the battery was fully charged and try playing the same songs. Said he thinks maybe my battery drained low enough to cause the amp to not function properly. I don't know... I have it hooked back up to my tender, so I'll try tonight after work, but I highly doubt that is the issue. It was hooked up to my tender all winter so far and fully charged before he started his install.
I just emailed him this AM asking about the DSP. I don't believe one was used. I told him, I wanted the "top of the line", meaning Carbons, best AMP, DSP, etc... so if one wasn't used, I'll have to ask him why. He did tell me if I was not completely satisfied he, he'd take the Soundz System back out and put the Boom II System back in at no cost and refund my purchase.
He did upgrade the Boom Box HU from the 6.5 to the new GTX. I'd 100% keep that, as that is night and day on boot and connect times to BlueTooth, not to mention Android Auto.
I put a Biketronics System in my '09 Ultra back in the day and honestly, right now... I think that sounded better.
I did just get a response back from the installer and he did send me a pic and verified that there was a DSP installed. He actually said that Soundz requires it with the Carbon's system. So Ya, I'm not sure what's up, but i'm very underwhelmed with what I'm hearing sitting in my garage. It's louder for sure, but quality at louder volumes is minimally better then what the Boom II is sitting still in the garage. Actually the Boom II even had a bit more bass to it.
