How car audio pricing works

$49 to find out exactly what your vehicle needs. The install is then one flat quote, approved before anything starts.

Head units & CarPlay retrofits

Quoted after diagnosis

Wireless CarPlay and Android Auto into dashboards that never had it. Steering-wheel controls kept where the wiring allows, factory look respected, quoted flat.

JDM & import radios

Quoted after diagnosis

Import head units with no English service documentation. We source and translate the service literature and map the harness first, so the install follows the maker's own wiring.

Car audio installs

Quoted after diagnosis

Amplifiers, speakers, subwoofers, and the wiring done so it neither rattles nor drains the battery. Bring your own gear or have us quote it.

Dashcam installs

Quoted after diagnosis

Hardwired to a fused, switched source with a low-voltage cutoff set. Cables tucked along the headliner and pillars, no dangling 12V plug.

Not the audio? Ask anyway.

$49

Anything vehicle-tech adjacent: backup cameras, phone mounts wired properly, factory-system oddities. If it is not our lane we say so at the diagnosis and you pay nothing.

The three jobs that come in most

Car tech fails and frustrates in patterns. These are the three we see weekly.

A dashboard stuck in the last decade

No CarPlay, no Android Auto, a radio that fights every phone you own. A modern head unit retrofitted properly fixes all of it in one visit, quoted flat.

An import radio nobody can work on

JDM head units ship with no English documentation, so most installers either guess at the harness or walk away. We source and translate the service literature first. Guesswork never touches your wiring.

A dashcam on a dangling plug

A camera taped to the glass with a cord across the dash works, until it melts a charging port or blinds you mid-turn. Hardwired to a fused source with a cutoff, it just works and stays invisible.

Three ways in

However the job reaches the bench, the quote comes before the work.

Bring the vehicle, or ship the head unit

  1. 01Bring the vehicle. 2224 Sunrise Dr, Longmont · Mon–Fri 9–6, Sat–Sun 10–3. Bench installs happen at the shop, so plan to leave the car for the appointment.
  2. 02Ship the head unit. Anywhere in the U.S.: get an RMA number online, pack the unit (not the car), and we diagnose within 24 hours of arrival and email a flat quote.
  3. 03Start online. The repair wizard gives a first-pass assessment any hour, and the AI receptionist answers the phone around the clock. A human follows up.

What we don't do

Scope stated plainly, so you know before you book.

Audio and tech, not electrical

  • No vehicle electrical diagnosis. Dead windows, no-start, charging faults, lighting gremlins: that is an automotive electrician's lane, not ours. We say so at the diagnosis and you pay nothing.
  • No anti-theft, immobilizer, or factory-security bypasses. We install and repair within the manufacturer's design, not around it.
  • No factory-system unlocks. Locked navigation or region-locked software stays locked unless the manufacturer's own procedure unlocks it.
  • No repair-avoiding part swaps. If a $6 connector fixes it, we don't quote a new head unit.

Car audio questions

The things people ask before they hand over keys or a radio.

Straight answers

How much does a CarPlay retrofit cost?

Diagnosis is $49 and free when you approve the repair. After that the install is one flat quote that depends on the head unit, the harness, and how much of the factory look you keep. You approve before any work starts.

Can you put wireless CarPlay in an older truck or car?

Yes. Most dashboards from the last twenty years take a modern head unit with wireless CarPlay or Android Auto. The $49 diagnosis confirms what fits your dash and what the wiring needs, then you get the flat quote.

My import radio has no English documentation. Can you work on it?

Yes, and it is one of the reasons this bench exists. We source the service literature, translate it, and map the harness before anything is spliced, so the install follows the maker's own wiring instead of guesswork.

Do you install gear I bought myself?

Yes. Bring the head unit, camera, amp, or speakers and the install is quoted the same way. We tell you straight if the gear is wrong for the vehicle before it goes in.

Do you hardwire dashcams?

Yes: fused, switched power with a low-voltage cutoff set, cables tucked, no dangling plug. The quote covers the whole job.

Do you fix vehicle electrical problems?

No. Wiring gremlins, no-start, and charging faults go to an automotive electrician. Audio and tech installs are what we take, and we say so plainly when a job is not ours.

Is there a warranty on installs?

Install labor carries a 90-day warranty. Equipment is covered by its manufacturer's warranty, and the quote states which is which.
