Bahi to phir JBL GTO 936e lo ... 4000 tak kay hain, way better than the Kenwood speakers.
@adeel, you have a hatchback with CNG right ? ... n you must have made a box on the parcel shelf for the subwoofer. You are choking your woofer, giving it HALF its intended space.
I met a guy with a similar setup, 715+subwoofer+amp ... he didnt even get punch INSIDE the car, and none whatesoever outside.
Throw away the box ... and try to exchange your subwoofer with a 'free air' one. JBL GT4 10" and Pioneer 303F are two cheap and good ones, JBL is better though. Cut a hole in your parcel shelf (get a new more stronger one made, and mount a bit higher too if thats possible. Put the subwoofer in that space wiht no box just like you mount a speaker. Let me know which subwoofer you have, it maybe free air compatiable.
