i had seen a stroker perform in an insane setup back in 99. that guy had two jbl 15 inch free air woofers, one stroker, 4 kenwood speakers, kenwood player and pioneer mid/tweeter set. you could hear it coming from a mile away. oh btw the car had 5 amps and 2 batteries. all this in a baleno.
Strokers and pure power and pure loudness. you have to get a proper tuned box and a really good amp for this.
