As most folks probably know, the Focal Amp comes with a Molex connector harness that hooks directly into the factory wiring connectors (rear speakers for the 2017 Ultra require splicing however). I did originally buy the two BT355's from Biketronics. For reference my flash is stock. I just kept adjusting the amp's gains and crossover settings both with and without the line levers installed. It almost seemed that the BT355s flattened a little too much... to the point the HU bass adjustment had little or no effect. After all the tweaking, this amp it just sounded better to me without the BT355s. If I were to add anything it would probably be a DSP, but they were more than I wanted to spend on this round for a non-Pro Audio install. I did return the BT355's and Donna was great on the phone, but very curious as they almost never get them back.

I do realize that I'm probably the outlier here BT355's....

 

So now my question would be have you had the bike out on the road since installing the amp? To my understanding it runs on a different bin file when the bike is running.

 

Probably have about 500+ miles on it after the install. Sounds great riding... too loud actually, makes my ears ring after a few hours on the road. May need to get ear plugs now (Ha Ha)...I only turn it up to about 1/4 to 1/3 volume at 70mph. Again, mine is not a PA install and my basis of comparison is to a stock configuration, but my riding group buds all want it on their bikes so I guess that's a testimony.

 

Good luck. I sure wouldn't want to be the ginnea pig on a $700 amp. Especially after folks far more learned than myself have repeatedly tested these HU's and they all claim at a minimum you need the BT355's. Not bashing you at all brother, I just hope you understand the consequences.

 

Thanks for the info...guess I will go 60A. Was the power line 8ga? I am trying to assemble all the right pieces before I am reunited with my bike.

 

We shall go forth blissfully ignorant and unafraid!

 

I was told by PS yesterday that their Focals are now shipping with the corrected harness.

 

Same harness with a patch cable on the end. It is on the standard harness but unplugs for the rca input cable.

 

yes its 8ga, and I guess I should think about adding a fuse to mine too. whats everyone using?

The Focal Amp comes with the 8 gauge power harness, just no fuse or end terminals for the battery.
