I have one in my waja and it does give me the right bass that i need. Consider it as a bass extension. What your components cant play, it plays. It does give a punch/kick like a sealed sub also, but still depends on where you locate it and how big is your cabin. As for me, im running a 10" mohawk underseat sub (yea i know, sounds like cap ayam, but i did audition a few which was under my budget, this sounded the best and gives me the umphh that i need) mounted below the dashboard of the passenger side.

Currently i dont have pictures with me now but i can upload later. My budget was RM500 for an underseat. I tested some MBQ, VSL, SONY, these 3 didnt meet my requirements untill i met that mohawk 10" underseat sub.


its definitely this type

since i dont even utilize the glove compartment. Its just below it screwed firing in-dash. Couple it with time alignment. It goes smack dead in the middle. I can even imagine the drum kick is right in the middle at the aircond/player area.
