Pioneer

I don't think it's any exaggeration to say that a good sub will make your car's sound system come alive, and Pioneer made their A-Series subs to give you the deep low-frequency punch that you want. The TS-A100D4 10" subwoofer handles up to 400 watts RMS while pumping out loud, clean bass. This sub features an injection-molded polypropylene cone that's impregnated with glass fibers and mica for exceptional precision and strength. A butyl rubber surround supports the woofer during cone excursion so you'll get accurate, hard-hitting bass notes even when the music's turned up loud. This potent Pioneer sub will bring out all the power in your music by filling in the lowest frequencies of the sound spectrum. Its dual 4-ohm voice coils give you more wiring options when setting up your system. Throw one or two of these subs in your daily ride, power them up with a nice amp, and you'll understand what the fuss is all about — whatever you listen to, great bass will make it sound much, much better.
