I wasnt really happy with the sound in the stock plastic bass box. I tried porting the box, dyanamap, rewiring with heavy gauge wire. I used the LC2+ for power switching and a class D bass amp. Still wasnt happy. I ended up adding another pioneer 10” Sub ($125) under the seat connected by a 1/4 phone plug so i can easly move it in or out. Wired both speakers at 4 ohms. Used the LC2+ mains-not the sub out. Wow...really happy now.
