Fwiw - I'm not sure if using the full length Tourpak antenna makes the difference, but my experience running a SD800.4S and a SD1200.4 EVOX presented no issues with the FM. I don't listen to FM much, but I'm not getting much in the way of interference.

That's interesting to know. Do you live in a city where there are several radio stations close by? Most folks I have talked to running SD amps have noticed a decrease in reception but I never asked them what type of antenna they were running. The type and location of the antenna definitely makes a difference. When I put the old style steel whip antennas on my 2010 (which came with the shorter fiberglass ones) I noticed a slight increase in reception.

Im running my antenna under the seat and with the SD amp I get virtually no stations. Stinger amp with same antenna no issues that I could tell.
Edit: I will say, I noticed the newer antennas.....not sure when they changed..... are not steel anymore. My 17 was steel. My 20 is not. When I reversed my antenna under my seat on the 20, some time later I had the seat off and noticed the tip had broken about 6" from the top. Not sure either of those discoveries would matter with FM reception SD amp or not.

I am in the same boat. The 1220 and the 2400 to almost all of mine out. Before the install. I could get most local stations sitting ( 8/10) in the garage, now only 1 or 2......dont really use it as I use Iheart for my local stations

The b-52 runs around 200w to each channel and that maybe your problem as the mmats start getting tinny above 150w or so. I suggest turning down the gains. Use a volt meter and dial them in at 3/4 volume to around 24-24.5 volts. They wont be as loud but you will hear the difference in SQ.

When using the pac nsi 15 it s the a different way to set the gain
