Good to hear. each day I'm getting more encouraged that this will turn out awesome with some more gain. ;-)
I knew I was setting it on the low side. I just can't believe that at a setting of 6 out of 11, and it's about the same as the 22 watts I was getting straight from the HU?

That Kenwood of yours has 4V pre-outs. The PBR300X2 should have your speakers jumping out of the fairing set on 6. . . .If they were two ohm speakers. You have the BTP7.1's and they are power hungry at 4ohms and 120 watts RMS. You are only throwing 100 watts to those power hungry speakers. therefore turning your gains way up to compensate for lack of power. I remember when I had the titan 2 set up on my bike with the X2 . . I never could get the speakers to reach their full potential with the X2. To get the sound you are looking for eventually you will have to graduate to the BT2180 or an amp with more power @ 4 ohms. Just my experience.

LOL. . It will sound really nice a low volume. Just don't try to turn it up too loud. Distortion City.

I am using the 300x2 from a stock HU, speaker level inputs and the BT7.1s almost exclusively running my ipod from my HDPD direct input. You MUST have something amiss as I can't turn mine up past 3/4 volume with gains set around 5-6 without pissing off the whole area around me. At 70 the bass is gone but otherwise sounds great. Although I have heard that the PBRs don't like the higher V inputs as well.

So I bumped it up to about 7 1/2 and it now cranks. I'm not sure why there is such a discrepancy but it seems my gain setting needed to be higher to get similar results. Once the weather cools down here I'll play with it some more but again last night I had 2 kids running around needing "daddy" every 2 minutes or so and I was sweating my *** off. So I got the fairing off, amp adjusted, and back together in about 1/2 hour. It is night and day difference between the 6 setting and 7 1/2.

Cool with 4 ohm speakers that should more than enough I ended up around 7. I noticed on this RF amp about 1volt difference between channels using my Fluke DVM. I do like separate channel gain settings like the Arc etc.
