Upgrade Your Factory Sound

The FLI AciD series is the perfect budget replacement to your factory speakers. These coaxial speakers are designed to be used in low wattage applications, making them the perfect upgrade to a set of factory speakers. The cone is composed of a molded polypropylene cone material, allowing them to provide articulate music reproduction while still allowing a punch lower end. Multiple polyetherimide supertweeters produce clean highs that your ears will love. The shallow depth of these speakers allows them to be mounted in a variety of vehicles. If you're looking for a low-cost upgrade for your door speakers that will bring the life into your vehicle, the AciD series is your calling card.

Cyber Monday deal

I purchased these speakers on cyber Monday. For the price, they are amazing! You definitely need a dedicated bass though. They hit the high notes really well, and can take a mild bass, but overall the sound quality is great and I would purchase another product by this company.

I purchased the 4in's and the 5.25in's for my WRX and the sound quality is MUCH better now! absolutely needing a dedicated bass though... thinking under the seat.
