Install services

What we install

Car stereo, ceramic window tint, car alarm, dash camera, and Harley bagger audio — done here in Carson.

Car Stereo Installation

A stereo install has to keep the factory functions that already work: backup sensors, steering wheel controls, backup camera, and on some cars OnStar, the front or scene camera, the mirror camera, blind-spot assist, and the warning chimes. Maestro or iDataLink is what lets the new stereo show climate, doors, and tire pressures. We build each job with genuine parts for that car.

Backup Camera Installation

We add a camera when the car already has an aftermarket stereo — that radio supplies the trigger. Luxury cars that never had a camera can need a separate module. We do those installs too.

Bass Amplifier Installation

Power comes through the firewall, fused and loomed, and the amp is mounted and grounded properly. If the car has an aftermarket radio, we pull it and run RCAs plus a remote wire. If it still has the factory stereo, a high-to-low adapter or a processor takes the signal, then RCAs go to the amp. Most cars take two to three hours; some European and EV cars take longer.

Four Channel Amplifier Installation

This is the longest install — the amp runs the speakers. Same power work as a bass amp, plus a full rewire: power on one side of the car, RCAs on the other, so the system does not pick up engine noise. The usual mistakes are a speaker wired backwards, which puts the system out of phase, or the wires run together, which brings engine noise in. Typically four to six hours, and the most expensive install.

Speaker Installation

Every car is different — front doors, rear doors, dash. We take the panels off the right way and put everything back right.

Subwoofer Installation

Enclosures that actually fit the car. Packages are built around how hard they want the bass, with the right cables and the install.

Full Sound System

A full system is a head unit or processor, speakers (four plus two tweeters, or six), a bass amp, and a sub. That covers acoustic, loud, or heavy bass. Some customers do it in visits — head unit, then speakers, then bass, then four-channel later. Others do the whole system at once.

Window Tint / Ceramic Film

Ceramic film is still polyester. The “ceramic” name means nanoparticles in the film that block heat, so you don’t feel the burn on your skin and a lot of the sun’s heat and UV stay out.

We hand-cut a micro-edge so the film sits seamless around the glass — not a computer-cut piece with a gap at the perimeter. Every car takes two to three hours in the shop. We treat the car like it’s ours and make sure it looks perfect.

Car Alarm Installation

A basic alarm covers doors and shock, starting around $269. Smart-key and keyless-go cars use the same alarm with a DB3 module so the factory fob, hand gestures, and keyless go stay. Remote start means finding the proper wires and stitching each one — no T-taps. Diesel trucks are a different job from a Dodge Charger or Challenger; some cars need a T-harness, and some need extra parts like DB3 and a bypass module.

GPS Tracker

An add-on to the alarm. Lock and unlock, start and stop the engine, and a notification if someone breaks in.

Ignition Kill

Sold alone, with an alarm, or with a GPS tracker. Once the car is locked, it will not start — even with the factory key.

Dash Camera

Thinkware front and rear, with an optional cabin camera, installed with the alarm work. Kits and remote-view options sit with the alarm, GPS tracker, and ignition kill on LA Car Alarm.

Harley Bagger / AMS Quick Disconnect

Harley bagger audio since the early 2000s. Crash-bar pods are built in-house, chrome or black — they sit on an angle and almost disappear behind the bar. Street Glide and Road Glide bags get a soldered line with a quick disconnect; Road King puts the amp in the bag on a carpeted board. The pods and the method are on AMS Pods.

Quick answers

From the shop

Why not buy a cheap CarPlay radio off Amazon?

A no-name Amazon CarPlay or Android Auto radio is not a safe buy. If it isn’t Pioneer, Sony, Kenwood, or Alpine, you’ll likely buy another radio soon — dead spots on the screen, it won’t pair, the camera won’t integrate, and the steering-wheel controls fail. We sell and install those name brands; we’ll still install a Boss or a generic unit from Crutchfield, but we can’t service the Amazon units — it’s the part, not the install. Call first for a real game plan — a payment plan is available, so you spend once, not twice.

Why hire a pro for a bass amplifier install?

On paper a bass amp is simple — power, ground, remote, and an RCA signal, and you have bass. In the car it is not: power through the firewall, fused, with the right terminals; panels off; cable routed to the amp, sometimes with the seats out; the signal and phase right; and a real ground. When it is finished it should look like it belongs there — no extra wire, nothing twisted. DIY jobs burn amps and equipment, and have put cars on fire; one mistake can kill the amp. Hiring a pro does not cost a lot next to that headache, and when the bass quits later you have someone to call.

Is oxygen-free copper wire worth it, or is a cheap CCA amp kit fine?

CCA is the basic amp kit, about $50. An oxygen-free copper kit is about $200, and it is worth it when the job needs it. One sub at a few hundred watts can run on CCA; two 12s around 2,000 watts will heat CCA until it melts, takes the fuse, and causes problems. OFC does not get hot, does not melt, does not corrode, and the system sounds better — people here play for hours, three or four a day, some all night, so if you are serious about audio, use OFC.

Why add a GPS tracker that notifies you?

In LA you leave the car for hours or all day — Vegas, the outlets, hotels, movie theaters. A GPS tracker with phone alerts (Viper SmartStart, Drone XC, DroneMobile) tells you if someone hits the car, opens a door, or tampers with it. A screaming alarm does not get the police called. This is peace of mind for the investment — people who leave expensive tools or equipment in the vehicle, and high-theft cars like Kia, Hyundai, Jeep, Dodge, and Chrysler. If it does get taken, you know where it is so you can get it back.

Compustar vs Viper — which alarm?

Compustar and Viper both make car alarms. They are competitors, they work differently, and we use both — we pick by the car. Compustar kills the ignition when you walk away, so the car will not start without your fob; that is what we want on Jeep, Dodge, Chrysler, and some newer cars where someone can copy the arm/disarm code and steal it. Viper has an electronic ignition kill you turn on — the right call on GMC, Ford, and fleet vehicles — but on those copy-code cars, unlocking with a copied code can disarm the Viper. Dodge gets Compustar. A diesel Ford gets Viper. Both are top quality. Come in or call and we will point you to the right one.

What stays working after a car stereo installation?

A stereo install has to keep the factory functions that already work: backup sensors, steering wheel controls, backup camera, and on some cars OnStar, the front or scene camera, the mirror camera, blind-spot assist, and the warning chimes. Maestro or iDataLink is what lets the new stereo show climate, doors, and tire pressures.

What is ceramic window tint?

Ceramic film is still polyester. The “ceramic” name means nanoparticles in the film that block heat, so you don’t feel the burn on your skin and a lot of the sun’s heat and UV stay out. We hand-cut a micro-edge in the Carson shop. Every car takes two to three hours.

How much is a basic car alarm?

A basic alarm covers doors and shock, starting around $269. Smart-key cars use a DB3 module so the factory fob and keyless go stay. Dash cameras sit with that work on LA Car Alarm.

Do you build Harley bagger audio?

Yes — Road Glide, Street Glide, and Road King, since the early 2000s. AMS pods are built in-house, chrome or black. Bags get an AMS quick disconnect. The method is on AMS Pods.

Hertz Neo or DS18 on a bagger?

DS18 is the cheap one. Huge magnet, hard and sharp, loud — not an acoustic speaker. Fine if you only want it to scream. Hertz Neo is the motorcycle speaker. Weatherproof, small magnet so it fits a bag and an AMS pod, and it stays clear when it is loud. It costs more. You hear the music, not just noise. That is what we put in the pods. Compare them on AMS Pods.

Hertz Neo or Cicada on a bagger?

Cicada is a serious motorcycle brand. People speak well of it. It also costs more than Hertz, and the magnet is huge — it eats most of the space in the lid. We ran them side by side. Hertz was louder and cleaner. Better performance in the bag. Hertz Neo is weatherproof, small neo magnet, so you keep the space. That is the one we recommend. Compare them on AMS Pods.

Do you do mobile installs?

No — everything is done in our own bay at 22025 S Avalon Blvd Ste A, Carson. Cutting tint on the vehicle scratches glass and risks defroster lines, so every piece is hand-cut on a glass board in the shop.

Do I need an appointment?

Walk-ins welcome Monday through Saturday, 9:30 AM – 6:00 PM. Come in before 4pm and most jobs go home the same day.

How long does window tint take?

Most cars are 2 to 3 hours.

Is your tint legal in California?

Yes — California requires front side windows at 70% VLT and we install to that spec. Windshield strips are 70, 50 or 35.
