I have Kicker 8 inch Subwoofer and I love it. Well, known the manufacturer and good quality product at affordable price. Super-rigid, an injection-molded cone with 360-degree back bracing and high-temperature coil wire. It also has vented pole piece for heat dissipation which is good to know. It is not that powerfull with 200 W but its construction and good materials use most of that power so the sound is good and strong.
It is maybe the best deal under 100$ and
loudest sounding subwoofer for that kind of money. If you are looking for the best value for your money, there isn’t anything better than this Kicker 10C84 8 inch subwoofer.
