If you want people to feel the music in your vehicle coming from a block away, you should definitely get a car subwoofer speaker. Subwoofer speakers are devices that will give the bass in your music a great boost and will help deliver some amazing sound.
Car subwoofer speakers, whether they are MTX speakers, JL Audio car speakers, or any other brand of car speakers, will really do a great job of complimenting the other speakers in your vehicle. Subwoofers only deal with very low frequency sounds, such as the bass drum or bass guitar in a rock song, or the drum kick or bass line in a hip-hop or R&B song. They are housed by car speaker enclosures and are usually placed in the rear or trunk of the vehicle. Subwoofers also typically require car speaker amplifiers to produce the wattage necessary to deliver deep, resonating bass.
Any car that thuds along the street with blaring music probably has subwoofer speakers. So, if you want truly deep, banging bass, you'll have to get yourself some car subwoofer speakers, speaker enclosures, and an amplifier. Once you have everything hooked up, the low-frequency sounds from your car's audio system should give you the sound you are looking for.
