Experience bigger, fuller, more immersive audio with the D5150.4, our 150-watt plug-and-play sound system designed specifically for the Evolution D5 (NOT compatible with the Plus model). This setup uses all four factory speaker holes—front and rear—to create a wider, fuller soundstage throughout the entire cart.
Powered by a Memphis MXA150.4 Marine Amplifier, four BA Signature 5¼” Marine Speakers, and our Soundbar BoostBox® head unit, the D5150.4 delivers cleaner signal, louder output, real stereo sound, and dramatically better clarity than the factory touchscreen could ever produce.
Zero wire cutting. Zero guesswork. Install in under an hour and finally enjoy the balanced, immersive audio the D5 should’ve had from the factory.

THE MISSION
NO FLUFF. NO SHORTCUTS. JUST QUALITY & ATTITUDE. THAT'S THE BA WAY.
Fill All 4 Speaker Holes – Bigger, Fuller Sound - The D5 comes with four speaker openings but no speakers. The D5150.4 fills every hole with high-quality Memphis/BA speakers, instantly creating a wider, richer soundstage that two-speaker setups simply cannot match.
True Plug-and-Play Installation- No cutting, no splicing, no wiring skills required. Every connector is pre-built, labeled, soldered, heat-shrunk, and designed to click together in minutes. Your neighbor could install it—seriously.
BoostBox® = Clean Signal + Loud, Clean Soundbar - The BoostBox® bypasses the touchscreen to eliminate noise, whines, distortion, and weak mono audio. You get stereo sound, louder output, and a soundbar that finally performs the way it should.
Balanced Audio for All Passengers - Two speakers up front + two in the rear = evenly dispersed sound, instead of blasting the rear passengers with the soundbar.
Dealer-Grade Equipment - Memphis MXA150.4 marine power + BA Signature speakers + professional-grade wiring. Zero cheap Amazon parts. Zero guesswork. All high-end components you can trust.
Stereo Audio Instead of the D5’s Half-Audio - The factory touchscreen only outputs the left channel. With the BoostBox®, your audio finally plays in full stereo—how your music is actually recorded.
Doesn’t Shut Off in Reverse - The BoostBox® keeps your music playing even when the cart goes into reverse.
Backed by Real Humans - You call us—you talk to the people who designed and built the system.
FITMENT
The D5150.4 plug n play sound system exclusively fits the Evolution D5 (4 & 6 passenger)
Bigger, Fuller, 4-Speaker Soundstage
Front + rear speakers deliver wide, immersive audio for all passengers to enjoy.
PLUG-N-PLAY INSTALLATION
No cutting. No splicing. No headaches. The harness, amp, speakers, and BoostBox plug directly into factory connectors for a clean, 30-minute install with basic tools.
Enhanced Soundbar + New Front Stage
The 4 speakers create a true soundstage while the BoostBox sends the soundbar clean, amplified stereo audio. The result: louder, clearer, more immersive sound from every seat.
DISCLAIMER
Once you install our D5150.4 sound system, you will no longer use the touchscreen as your audio source, which means your FM Radio and USB Thumbstick port will not work. You will ONLY be able to listen to music via bluetooth using your phone while connected to the BoostBox.
WARRANTY
Our 1 Year Limited Warranty covers defects in materials and craftsmanship for one year from purchase. (Doesn’t cover misuse, improper install, or normal wear.)

"The boost box made a large difference in the factory speaker bar adding the speakers in the amp just added another dimension to the Soundsystem so totally happy with everything. Service was friendly. Shipping was next day. I got stuff next day. That’s awesome....."
I purchased the D5150.4 four speaker system with D5 soundbar Boostbox and Memphis amp. The installation instructions were well written and easy to understand. The only burp was the rear speakers were not sized correctly. Apparently, Evolution made D5 Mavericks with different speaker ports and for my installation, I needed the larger speakers. BACarts sent new larger speakers as well as a pre-paid return box for the original, smaller ones. The system really does kick the sould quality up a notch! SO much better than the stock system.

Fantastic plug and play stereo
Installion QR code worked great for front speakers, Amp and boostbox. Just a note, Video had no info for rear speaker assembly. Was easy enough to figure out. System sounds great. Would definitely recommend

Great Product
Positives
Overall product is great.
Sounds really good, WAY better than just the soundbar.
The pre wiring was extremely easy to plug and play
Not so positives
Please update the instructional video it is very out of date, but helpful enough to get the job done. Also would be awesome if a rear speaker video installation was made.
I get a humming from the speakers when I start my golf cart. Goes away after about 10 - 15 seconds but don’t love it.

A necessary upgrade if you use a sound system!
Super easy install, especially after watching Sloan's video. Hardest part was zip ties! That should tell the story. Sounds great as well!
