What size speakers fit your 1990 Chevy truck?

The size of speakers that fit a 1990 Chevy truck depends heavily on the *trim level* and whether the truck is a C/K series (full-size) or an S-series (compact). There's no single answer.

To find the correct size, you need to do one of the following:

* Check your existing speakers: The easiest way. Remove one of your speakers (carefully!) and look for numbers printed on it (often including a diameter in inches like 6x9"). This is the most reliable method.

* Consult a parts store website: Websites like AutoZone, Advance Auto Parts, or NAPA Auto Parts allow you to search by vehicle year, make, and model. Entering your specific 1990 Chevy truck details (including the model - e.g., Silverado, C1500, S10) will show you the correct speaker sizes.

* Look in your owner's manual: If you still have the original owner's manual, it may specify the speaker sizes.

* Consult a car audio specialist: A local car audio shop can quickly identify the correct sizes.

Without knowing the specific model of your 1990 Chevy truck, I cannot give you a definitive answer. The doors and dash often have different size speakers.
