What We Install
Start with a goal. Leave with a build sheet. Nick quotes labor — this is not a cart and not an installed total.
Kenwood and Pioneer head units, plus ZZ2 luxury integration when the factory screen stays.
ZZ2 dealer. Factory-screen CarPlay and Android Auto for BMW, Audi, Lexus, Mercedes, Ford.
Kicker-led power, Stinger wiring, grounds that stay quiet on South Bay pavement.
Kicker boxes in stock — dual 12s, L7, L7R, CompC, CompR, truck and downfire. Dual Comp $249 house special, box only.
Tweeters aimed. Crossovers mounted. Kicker, Hertz, Focal, JBL.
Analog line converters when the factory radio stays and the amp needs a clean signal. Epicenter on cars that need the bass restored.
Road Glide, Street Glide, Road King, and Softail sit on AMS Pods. Hertz Neo in the pods. We do not put JBL on a bagger.
Brands We Trust
Kicker shows up in more of our car audio builds than any other brand. Pioneer, Kenwood, JBL, Hertz, and Focal fill in the rest of the car work. Harley bagger audio is a different page — Hertz Neo, not JBL.
Kenwood DMX9707S multimedia receiver — photographed in shop inventory alongside JVC head units. Kicker boxes and amps are on the floor.
From the bay
A real Audio MotorSports job: a Ford Bronco with a full stereo upgrade, eight hours in the Carson bay.
Kicker, Focal, Hertz, Pioneer and Sony installs from this bay, on video, brand by brand.
Text the year, make and model and what you want to hear. Nick sends photos of a similar build and a price.
Why LA Car Beats
Collective shop experience across stereo, tint, security, and bagger builds — not a count of individual installers.

Questions
Yes. A stereo install keeps the factory functions that already work, including steering wheel controls and the backup camera. Text Nick the year, make, and model so the quote matches that car.
Yes. ZZ2 adds wireless CarPlay and Android Auto on the factory screen, so the radio you already have stays. Steering wheel controls stay with it. Some cars still need a new head unit. Text Nick the year, make, and model and he will tell you which path fits.
Book a 10:00 AM or 12:00 PM slot, Monday through Saturday. Most amp installs finish the same day in the bay. Text Nick the year, make, and model so he can say if that car needs more time.
Yes. Bring the head unit, amp, or speakers and we install them. Text Nick what you are bringing and the year, make, and model. He quotes the install for that car. Booking a slot does not take a deposit.
Yes, on head units and on install-only work. Text Nick the online listing and the year, make, and model. We match that price when the part is the same. Full custom builds stay a quote.
Yes. A Payment Plan is available. Open the Payment Plan page to apply, or text Nick and he will send the link. Booking a slot does not take a deposit.
Yes. Book a slot or text Nick. Same-day is possible if you arrive at 9:30 opening, Monday through Saturday. Sunday the shop is closed.
