That B52 is an interesting little amp. I noticed a weird socket on it labeled BTR port. Their website mentions connecting a Bluetooth receiver though this port but I don't understand the concept. I thought Bluetooth was handled inside the head unit itself. Are there special Bluetooth receivers that plug directly into amps now?

 

been reading...tell me if this sounds right. Turn amp all the way down. Raise volume until distorted then back off till clean. Turn up gain till distorted then back off till clean. Done?

 

Well almost. If you turn down the gain on the amp all the way, it wont matter what the hu volume is, you wont hear it. Turn the volume 3/4 up. Start adding gain until distortion. Then back it off a tad. Make sure the hp filter is on and around 80 or so. That should get you close by ear and make those kappas sing. If you have a digital volt meter, there is a sticky thread on how to set up you amp based on watts and ohms of your speakers. Very helpful.

 

Wow I can't believe how much extra room is left over with that amp vs. the SS PN4.1000d. I know that bike isn't an ultra with the extra head unit harness but that is a really impressive package.

 

 

I believe the instructions sat they are for when installing the with a stock HK head unit. I basically disregarded the instructions for them as I was installing a sony head unit.

 

Yea. On that amp it is marked x over. Switch it to hp. Just to the right of it is the freq. ****. Turn it till you think it is about 80-90. Should be good to start taking your gain (sens) up till you hear distortion then back it off a bit.

 

I haven't read through all the Replly within the thread but yes there is. Order a Bluetooth Fusion adapter, works wonders and I never had an issue with the one I had on mine before changing out the head unit or others I have installed it for on both bikes and vehicles.
