did you have to add a second battery I had to on my cage

No sir. I have a Braille Lithium battery under the seat. The 3 amps I run, total 5850 watts, not that I'm utilizing all of the available power. I have friends running dual batteries, but they are running close to 12k in amps.

Hence problem is not the size of sound amps, but the amount of extra amperage off the charging system needed, to be able to keep the sound amp feed the amperage its needing, with extra amperage the bike is not using to begin with.
And note, when the charging system burns down from the aftermarket amp, HD is going to void the warrenty, and charge you for the repairs.

And the charging system burn up parts, concept is charging system is not taxed 100% of the time, which allows the parts to cool back down, which is not going to happen when it being taxed 100% of the time with amp in play.

And is kind of funny, since see the same problem with the BMW GS riders, adding way too many extra lights that taxes the hell out of the charging system, that burns the charging system up as well.
On the positive note, on the Harley, only need to pull the primary to get to the stator, while on the BMW R motors, have to pull the motor out of the bike, then trans off the back of the motor, to get to the stator that's within there.
well aren’t you Sunshine and rainbows🤣

Default Update 2026

Two years strong and no stator issues, did end up getting RF stage three speakers since I wanted metal grills and had some points to use at HD.

Rockford is super simple and plug/play but not loud enough and the “Modified” Kenwood alternative is too pricey for the amount of wattage they provide and you still have to do several things. The “Modified” part about the Kenwood XM160-2 is that it has a remote turn on wire which most amps already do. They use the factory amps speaker leads to plug into the Kenwood’s hi-input instead of using rca cables. The Kenwood still requires power being routed and the remote turn on connects to a purple/blue remote wire in the Harley stock wire harness inside and under the fairing (this can be done with any amp that has a hi put option and a remote power).

I will be using a stealth 1000w amp that I had in my previous street glide & I will use two sets of 2 pin connectors (currently unavailable from Harley) to tap into the stock amps output and then plug into the speaker leads. I have not decided if I will try to de-pin the harness for the remote power wire or just use a wire tap but I’ll decide this weekend.

All said and done this is under $300 since I found a good deal on a set of midrange 6.5’s on sale that I wanted to try.

Here are the molex 2 pin connectors if anyone else is interested in doing something similar. Part #33481-0201 & #33471-0206

This is the amp that I will be using again. It performed well and I never had any issues before.

Oh but the Stage 3 Rockford front and in saddlebag lids sounds out of this world.

Completely an arm and a leg above stage 2.
Pun intended

Our HD dealer has specials on these, 50 percent off labor and also off parts.

The base is unbelievable.
Good luck whatever you choose.
Mike.
