I need to find the light bulb that goes inside a Rockford Fosgate FNQ crossover. Tried googleing the product number and looking around RF site but got nothing.
The product number is HDW10932.

Any lamp that will fit will work. Literally. On the end of the lamp will be a rating, possibly in voltage, but certainly in wattage. The wattage is the important number. Any auto parts store SHOULD be able to get you close to the part, but really, physical dimensions are the most important part. All it does is present a dynamic resistance, one that goes UP as the power through the resistance increases. It's for protection of the tweeter.
If you want, (and these lamps will be SO cheap) you could replace the other one at the same time, that way IF there are any differences between the OEM one and the replacement, replacing them both with identical lamps will remove any differences, and the tweeters will end up with the same resistances and protection values.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
