There are many different brands when talking about car audio, but there is one brand that leaves most people wondering exactly who they are. This brand is usually tight-lipped about their products and is even pickier about the retailers they allow to sell their product to the masses. The brand I am speaking of is Crossfire.

Crossfire was started in the early 1990s by some car audio enthusiasts who were tired of the low-quality brands, and the higher-priced, US-built car audio. These car audio entrepreneurs decided they were going to create a brand that melded the high-quality and performance of the US-built brands with the lower-cost imported brands. With this marriage of the two, Crossfire was born.

Crossfire, during its tenure, has become known as one of the premier car audio manufacturers in the business. They have also become the leader in the OEM amplifier niche. 

Even though Crossfire has been limited their authorized retailers, you are in luck if you have been looking for Crossfire for your car audio build. Down4Sound Shop is an authorized online dealer that carries all of the most popular Crossfire subwoofers and amplifiers. That said, let’s take a look at some of the Crossfire subwoofers, amplifiers, and speakers that we stock here at Down4Sound Shop.
