Boat, UTV and Golf Cart Audio: Marine Speakers, Tower Speakers, Subs and Stereos Compared

Pick 6.5-inch marine coaxials like the Alpine SPS-M601 or Kicker KM 45KM654L to replace worn speakers in a boat, or the JL Audio M6 8.8-inch for more midbass from a bigger opening. Pick the Alpine SPV-65-SXS pods for a side-by-side, UTV or golf cart roll bar, and tower speakers like the Kicker KMTC 45KMTC65 or KMTCXL 51KMTCXL65 for a wake tower. Add a marine sub like the Alpine PWE-S8-MRN under a seat or an infinite-baffle sub like the JL Audio M6-10IB in a panel. Call or text us first, before you come in, to set up boat, UTV or golf cart work.

Why marine-rated gear

Out on the water or the trail, speakers face sun and spray. The marine gear in our listings is built for that: depending on the model, the listing names UV-resistant cones or grilles, sealed or water-resistant parts, stainless hardware, an IP rating or salt fog testing.

Every piece here is on our listings. We are an authorized JL Audio, Alpine and Kicker dealer. Call or text us first to set up boat, UTV or golf cart work: tell us what you have and what you want to add, and we will go over the parts and the plan with you.

Side by side

This table is built only from our own product listings. Where a listing does not state a spec, the cell says so instead of guessing.

IP ratings and salt fog or UV testing tell you how a speaker is built for the outdoors; where a listing does not give one, ask us before you count on it.

Marine and powersports speakers and subwoofers compared, from our product listings. "Not in our listing" means our product page does not state that spec, so ask us before you count on it.

Marine speakers for the boat

The Alpine SPS-M601 is rated IPX5, tested for salt spray and fog, and its listing says its efficiency lets it run from a marine head unit without an amplifier. The Kicker KM 45KM654L adds LED lighting, sealed motors and 316L stainless hardware, and the Kicker M-Class 51MSC65 uses carbon-fiber-infused cones and waterproof connectors for the speaker and the lighting.

The JL Audio M3-650X-S-Gm-i adds RGB LED lighting on a separate lead. The JL Audio M6 7.7-inch fits many openings made for 6.5s while giving extra cone area, per its listing, and the M6 8.8-inch and Alpine MRN-S88-LW are big-cone speakers with more midbass; the Alpine is IP66 with Deutsch connectors and an RGB LED grille.

UTVs, golf carts and wake towers

The Alpine SPV-65-SXS pods clamp to 1.5 to 2-inch bars on side-by-sides, UTVs and golf carts, with IP55 drivers in IP65 enclosures. For towers, the Kicker KMTC 45KMTC65 cans clamp to 1.5 to 3.25-inch tubing, the DB Drive APT65RGB has swivel clamps and RGB lighting, and the Kicker KMTCXL 51KMTCXL65 uses horn-loaded compression drivers in cans that rotate 354 degrees.

For bigger towers, the JL Audio M6-880ETXv3 is an 8.8-inch enclosed tower speaker with 10-foot flying leads, and the Kicker KMFC 47KMFC9 is a 9-inch horn-loaded speaker made for flat factory tower hardpoints with 2.5-inch bolt spacing.

Marine subs and stereos

The Alpine PWE-S8-MRN is a powered 8-inch marine sub with a 120 W RMS amp in a low-profile IPX6 box that fits under seats and consoles. The JL Audio M6-10IB and Alpine MRN-W12S4-IB are made for infinite-baffle mounting in a boat panel, and the Kicker KMF 45KMF122 is a free-air 12-inch that plays bass without a dedicated box.

For the head unit, the Alpine UTE-M701 and UTE-MN801 are waterproof marine receivers with sunlight-readable screens; the UTE-MN801 has a 6-channel amp and dual-zone control. The JL Audio A60 runs four audio zones with NMEA 2000 networking, the A60-H is the hideaway version controlled from a chartplotter or app, and the JL Audio MBT-CRXv3 is a compact Bluetooth controller for streaming without a full head unit.

Car Security Guide: Viper Alarms, GPS Tracking and Dash Cams That Record While Parked

For an alarm, Viper is the brand we install: the 3108V and 3308V add an impact sensor, six-tone siren and starter interrupt, and the 5308V and 5908V add remote start. To know where the car is, the Viper VSM550 SmartStart Pro adds GPS location on demand, SmartFence, speed and tow alerts and alarm notifications on your phone, with a service plan. To have video of what happens while you are away, pick a dash cam with parking mode, like the Thinkware U1000 or Q1000, hard-wired by the shop.

10-Inch Car Subwoofers Compared: JL Audio, Kicker, Alpine and Focal

A 10 fits smaller boxes than a 12. For a first sub on a modest amp, look at the Alpine W10S4, Kicker 50CWCD104 or 52CVR104, or JL Audio 10W0v3 and 10W1v3. For a truck cab or under a seat, pick a shallow 10: the JL Audio 10TW3-D4 and Alpine RS-W10D4 mount 3.25 inches deep, and the Kicker 48CWRT104 and 46L7T104 need 3-7/16 and 3-3/4 inches. For more output, step up to the Kicker 50CVX104 or 44L7S104, the Alpine S2-W10D4 or R2-W10D4, or the JL Audio 10W3v3 and 10W6v3. At the top are the JL Audio 10W7AE, the Alpine HDZ-W10 and the Kicker L7X.

Questions on Boat, UTV and Golf Cart Audio: Marine Speakers, Tower Speakers, Subs and Stereos Compared

Why pick marine speakers for a boat?

The marine speakers in our listings are built for sun and spray: depending on the model, the listing names UV-resistant cones or grilles, sealed or water-resistant parts, stainless hardware, an IP rating or salt fog testing. Ask us about a specific model before you count on it.

What speakers fit a UTV or golf cart roll bar?

The Alpine SPV-65-SXS pods clamp to 1.5 to 2-inch bars. For larger tubing, Kicker KMTC tower cans clamp to 1.5 to 3.25-inch tubing. Measure your bar first.

Can I add bass to a boat?

Yes. The Alpine PWE-S8-MRN is a powered 8-inch marine sub that fits under seats, and the JL Audio M6-10IB and Alpine MRN-W12S4-IB mount infinite-baffle in a panel.

Do I need a marine head unit?

Not always. The JL Audio MBT-CRXv3 Bluetooth controller streams from your phone. For a full receiver, look at the Alpine UTE-MN801 or JL Audio A60.

How do I set up boat, UTV or golf cart work?

Call or text us first, before you come in, to set up boat, UTV or golf cart work. Tell us what you have and what you want to add, and we will go over the parts and the plan with you.
