i havent heard of either of those brands. but it is traditionally preffered that your sub woofers face the trunk lid. also try adjusting your amplifier. there is a switch on it that should adjust if it is music, music and bass, or just bass that goes to your sub. then there is gain. turn the stereo on and adjust the bass on the headunit to its normal setting (if its a scale of 1 to 10 put it at 5) then adjust the gain on the amplifier with music playing at the normal listening volume. this increases bass power. do this untill the sound is distorted and then back off a little.
