Well, I installed my amp on Saturday and it's very nice. Very simple straight foward. In the garage it was almost to loud, but is alaways to lound in the garage. So I got out on the road for a bit and i could really tell the difference. The sound is much clearer and crisper. That is also runnig the older HW BT-504 speakers, really should sound "most excellent" with the newer sx or cx speakers. I even installed it on a friends 08' Road Glide before I put it in mine and HD stock speakers never sounded so nice. So my friend has started to save some $$ for his upgrade. One thing I learn and advice for the next person to do the install. Disclaimer, this is on my 05' SEEG, so I magine is the same on and 04' SEEG. Don't know about the 06' and up.
The location on the amp is. All the way back almost touching your gages on top of your existing radio. That means that you have to make it fit in between the radio and the big fat wire loom that runs on top of your radio. First I just put as far back on top of the radio against the wire loom. NOT FAR ENOUGH, the faring would hit. And yes if I would of pay close attention to HD Dudes pics. on the first page, that 's exactly how he did it. Under the loom. I had to pull one of the loom anchors out and presto Nice and tight under there.
I do have a pop that sounds when you turn off the bike, like the amp is powering down. It didn't do it on my friends 08' RG, so I called Jim and he's going to call HW and take care of it. Sorry for the long read. Laaaaaaaaater, Let's Roll
