Everyone knows audio is a simple and effective mod for your car, and if you want simple and effective bass, check out this TS-WX304T Sub from Pioneer.
The TS-W304T boasts a nutty 1300-watts peak power and is designed for low distortion and powerful bass at high sound pressure levels.
All terminals are at one end of the specifically designed tube for easy installation.
And if you want to build on the bass, the looks of this sub are deliberately similar to Pioneer’s GM amplifier lineup.
So, premium sounds at a competitive price: you can’t say fairer than that!
