O5 TUNDRA 4 DR SUB OPTIONS

THE ONLY THING IVE SEEN IS A BAFFLE BOARD WITH 2 EIGHTS IN THE SPARE COMPARTMENT UNDER THE LEFT REAR SEAT.... I TRIED IT AND IT SOUNDS LIKE A S S ! THE SPEAKERS FIGHT EACHOTHER AND WHEN I UNHOOK 1 THE OTHER ONE SOUNDS BETTER BY ITSELF CAUSE THERE IS NO FIGHTING OR CANCELATION!... ANY OPTIONS? MABEY A SINGLE 10? BUT SPACE IS REAL LIMITED.... THE INSIDE OF THE WELL GOES DOWN IN A "V".. SO MAGNET SPACE IS LIMITED.. AND WHEN YA FOLD THE SEAT INTO SITTING POSITION, THE BASE IS RIGHT UPON THE TOP OF THE BOARD...

ANY SUGGESTIONS????????? THANKS IN ADVANCE!
