The Crutchfield Vehicle Research Team

Working hard to make your stereo installation easier

In a nutshell: No one else in the consumer electronics industry does the kind of stuff we do. That’s why no one else knows what we know. Here's a brief look at how Crutchfield's Vehicle Research Team does what they do. 

Here at Crutchfield, we've been selling car audio gear for over four decades now. For most of that time, we’ve been taking cars apart to find out what fits.

Way back when, we started by taking our own cars apart. We then started visiting junkyards in search of even more fit information. It was hot, dirty, and occasionally "snakey" work, but it was worth it.

Old school research

In the old days, our field research was often done in an actual field. (Crutchfield Research Photo)

In-depth research

We’ve come a long way since those days. Now, we have a dedicated research facility, access to a wide variety of current models, and a database of over 27,000 vehicles — and counting.

And that database isn’t just a list of makes and models. It’s an incredibly detailed collection of measurements, photos, footnotes, instructions, and the kind of knowledge that comes from doing the same work our customers are going to do later. No one else in the consumer electronics industry does the kind of stuff we do. That’s why no one else knows what we know.


Every step of the process is documented by our Vehicle Research Team (Crutchfield Research Photo)

Step-by-step documentation

The process begins when the car rolls into our garage. There, veteran researchers Ben and Wayne get to work. Each step in the factory stereo removal process, from the dash to the doors to the rear of the vehicle, is documented with incredibly detailed notes and upwards of 400 photos.

Most car audio sites check the size of the radio and that's about it. These guys check the size of the radio, then they check the shape of the dash, the depth of each vehicle's radio cavity, and any possible obstructions in the cavity that might come into play when you try to install a new receiver. They also test the dash kits and wiring harness adapters that are needed to install your new stereo gear. 

When it comes to speakers, they measure the cavities, but they also check several additional measurements, including mounting depth, mounting height, magnet diameter, cutout size, and exactly how they mount in each vehicle. That's why our website will sometimes say, "Nope, sorry, not gonna work." when others say, "Yeah, sure, it'll fit!"

Around 150 cars go through the full research process each year, and numerous others roll into the shop when the guys need to take a quick look at a factory system they haven't seen. For a garage that doesn't do oil changes, it's an incredibly busy place.

Is all of this a little over-the-top? Maybe, but as the old saying goes, "Nothing succeeds like excess." Part of the reason for Crutchfield's success over the years has been our dedication to doing what some would say is excessive amounts of research on the gear we sell. And yes, it is a bit excessive, we suppose, but it's what we do.

Lots of data, lots of benefits

The raw numbers are entered into our massive vehicle database, along with detailed footnotes that explain any issues that could arise when you try to install certain gear in certain vehicles. All this info comes into play when you speak to a Crutchfield Advisor or enter your vehicle information into our Outfit My Car page. Instead of wading through a bunch of stuff that doesn't work, you’ll go straight to what fits your car. From there, it’s just a matter of using Crutchfield's shopping tools to choose the installation gear you need to install the new stereo components in your car.

If you have installation questions, you can call, chat, or email our Tech Support team. These electronics experts can frequently refer to our database and find a photo of the exact area you're working on. When you need help, we know what you’re talking about, and we probably know what you’re looking at.

Dedicated to the do-it-yourselfer

For most customers, the most tangible benefit of all this work is our famous Crutchfield MasterSheet™. Created by Tom, a car audio expert and 22-year Crutchfield veteran, each MasterSheet contains installation instructions, photos, wiring information, and even a tool list.

For select low-volume vehicles that don't have a MasterSheet, we've created Crutchfield ResearchNotes™. These photo-filled instructions contain the info you need to handle your installation. They're sent via email with your order confirmation, so you can print out the sections you need, or just pull up the info on your laptop or tablet in the garage.

Though the info they contain is priceless, these documents still included free with car stereo and speaker purchases from Crutchfield. Or you can order one separately for $9.99.

Even with step-by-step instructions in hand, a lot of people are intimidated by the idea of “doing it themselves.” That’s why we created the Crutchfield Research Garage. This ever-growing collection of web articles gives you an honest assessment of what’s involved in replacing the stereo system in your car, truck, or SUV. If the job is easy, we’ll tell you all about it. But if it’s difficult or nearly impossible (rare, but it happens), we’ll tell you that, too. We want you to do it yourself and do it right, but we also want you to know what needs to be done.

As you might imagine, the smart fortwo has a couple of quirks, but as our Vehicle Profile article in the Research Garage explains, it's a reasonably uncomplicated vehicle for the do-it-yourself car audio enthusiast.

    I bought the pioneer 1400 nex head unit for my 2012 corvette a month or so ago and y'all sent the installation guide in an email to me. Unfortunately my email auto deletes after a certain number of days and I forgot to save the installation guide for it. Could y'all send it again please?

    Ebrahim, The cavity depth is roughly 1-3/4". When you enter your vehicle's info into our Outfit My Car tool, you can see all the speakers that fit your car. If you have any questions, our advisors are available via phone or chat.

    Earl, We're not intimately familiar with that particular powered sub, but we're pretty sure you'll need an amp wiring kit for your installation. Give us a call and talk to one of our advisors. We can help you choose the right gear and give you the right advice on how to install it.

    Is it possible to have a combination of both a cd player and a cassette tape deck system in cars built fro y2000 -y2017 ?

    Jon Paulette from Crutchfield

    on 6/8/2018

    John, There aren't many CD/cassette combo units out there anymore, alas. Depending on the car you're talking about, you might be able to find an OEM-style replacement, though.
