Car Subwoofer Boxes & Enclosures for 8-Inch Subs

If you are looking for a small subwoofer box to fit a tight space or simply just to add a little bit of low end to your car audio sound system, a Car Stereo 8-Inch Subwoofer Box may be your best bet! Because of their size, 8-inch car audio subs can generate remarkable crisp bass in a variety of enclosures. The sealed enclosure will yield the best result and the tightest, most accurate bass compared with other subwoofer sizes. However, high-performance, high-quality competition-style 8-inch subwoofer with big excursion are known for delivering deep bass and SPL when loaded into ported (bass reflex) and even bandpass enclosures. If you are unsure what to look for, consider an 8-inch car stereo subwoofer enclosure loaded with a driver with a competition-grade pressed paper cone, a high roll foam surround, and a high-temperature copper voice coil two inches in diameter or larger. Like always, there are exceptions to the rules, and there are some ultra-high-performance drives out there with neodymium motors exotic cone material like carbon fiber and r Kevlar but have the tendance to be a bit pricey. On the other side of that argument are those not into subwoofer box building. Don’t worry. Consider one of these loaded or empty 8-inch car stereo subwoofer enclosures, and you can’t go wrong!
