I have 2 12inch subs in a ported box in my trunk facing back would the bass be any better if i turned them facing front or does it matter ? The bass in the car is massive but out side not to much except you can hear the trunk rattle i want more bass to the front not the back. i want to rattle the car in front of me not the behind me .On a different matter what makes the subs hum when the amp is on and the car is running the amp kit is new the amp is a dual 600 watt 4 channel amp and it is bridged 8 gauge power and 8 gauge ground in line fuse twisted component wires(RCA Cables) and nothing touching or any open wires
For more bass get a more powerful amp and use a smaller gauge wire like 4 or 0 gauge and a mono block amp is good for bass. But if you turn them facing inside the car and let the rear seat down you will achieve your goal.
NO, turning the subs around will not produce a better sound(vibration) unless the subs front wall is completely cealed off from the trunk which means you would have to have a custom box. but in most cases like yours it will actually reduce the sound. the trunk is basically a expansion area.bass extension comes from space within the trunk. the trunks surface area resonates the subs movement and redirects it into the cabinet. that's why you lose sound pressure when you open the trunk. this fundamental is quite complex actually and requires tuning of the box and subwoofer. a good way to increase sound pressure and extend the subs motion into the cabinet is by making a port into the cabinet for example letting a seat down or if you have a armrest that has a trunk opening area, that can be used as a port to allow the sub woofer to resonate the area within the cabinet but this can also allow more subwoofer distortion to be heard aswell. it requires alot a padding and dampening material to reduce the amount of sounds leakage and rattle distortion. you have an improper amp for sub woofers is probably the reason why you might not feel proper lows. the humming sound can be from a variety of reasons. but the sound itself is distortion from either improper filtering, or a lack of energy to the amp, if you have the gains set high on the amp you are over the distortion limit and are probably under powering the amp to produce a proper wattage and normal levels. OR you are getting distortion from your head unit, which is not uncommon. what type of subwoofer and amplifier do you have by the way.
