Hogtunes Big Ultra Stereo Upgrade Kit For Harley Ultra

If you're wanting to upgrade your factory stereo or you are building a ground-up custom system, the Big Ultra Kit is the way to go. It drastically improves sound, is a snap to install, and doesn't even interfere with your bike's AVC (if so equipped). Listen to a Hogtunes system and just see if it isn't one of the best bang-for-the-buck products out there!


  • 4 - 5.25" 2-ohm speakers - compatible with factory equipment
  • 200 watt amplifier maximizes output with no strain on the charging system
  • NCA amplifier (Not Car Audio!) mounts to top of radio in the fairing
  • Amplifier is fan-cooled and has a 'dish' cut into it so the speedo/tacho harness has a place to rest
  • Kit includes a 100% "plug-and-play" harness and everything needed to complete the installation

Note: A downside of any Class D amplifier is that they can upset FM reception-especially when using an in-fairing style antenna. The new model amplifiers have had tweaks done inside and have had the wiring harnesses upgraded to help stop interference, but depending on the quality of the antenna on the bike, FM interference could still happen. The vast majority of people with stock antennas will have no issue, however, if you already have, or want to go to an in-fairing antenna, please consider this before making your purchase decision.

These speakers have a lot of sound but are a little flat sounding, not a lot of bass or mids. they work well tho for the money. Also don't be surprised when the colors of wires in the installation manual is completely different than the actual wires. It is still easy to install and everything fit perfectly

Hey guys,

I'm riding a 11 Electra glide ultra limited, and so far the stock speakers were doing it for me. I might be considering an upgrade. I'm interested in the set, and was wondering if the 7" woofers you guys have installs with this? Basically was thinking of putting in the woofers in my empty storages mounted on my crash bars.

BEST ANSWER: Yes you can integrate the lowers by either using the Bypass port(RADIO POWER) or adding another amplifier to the system, or lastly running the rears off the radio and the lowers off the amplifier Rear Out
I have a 2013 limited. Wanted to upgrade the four speakers and add an amplifier. I have a detachable tour pack so the amp will have to be an in-fairing. Do I have to switch anything on the amp when the tour pack is removed eliminating the 2 rear speakers. If so can I make that adjustment without opening the fairing?

Does the Hog Tunes Big ultra Upgrade Kit (amp/4 speakers) system include the amp mounting brackets? I am assuming it is compatible with the stock 2013 Harley radio.
Thank you
A shopper on Apr 29, 2015

Yes this does come with the mounting brackets. Make sure you take the time and read through the directions a couple times and this install with go smooth.
Will the fairing tweeters plug into this amp?
