so i installed my sub yesterday (with no knowledge of car audio, i was proud of myself ) and it's sitting in the trunk, but i was wondering if it's supposed to face a certain direction. like, does it yield better results if faced towards the back seats or the rear of the car?

well mine is on its back facing up. but it faces towards the front a bit. it depends if you wana show it off and having facing outside the truck or toward the front and get more of the sound.
there are a few options but it doesnt rele mater because bass is better distributed than usual sound because it is low frequency.
not sure if i confused you but hope it helps

also, would my s**t bump more if i had a head unit that controlled the subwoofer alone?

the one i have now only controls the low end on all the speakers, not just the sub.

I'm no expert, but your speakers shouldn't be producing any lows (which is why you have a sub). I believe that Crutchfield sell bass blocker for your speakers. As far as adjusting your sub, don't you have a gain control on the amp?

I would place it facing the rear of your trunk.. It sounds louder and deeper cause the sound waves have something to hit.. I tried alot of different set-ups and it would better that way. what head unit,amp and sub are u running??

on my head unit you can switch between the front speakers and rear (subs) so u can vary the amount of power goin to each having more at the front or the back. thats what i use and my unit is a Sony. you cant control the gain from a head unit as far as i no.
as for the gain, u shud ajust that by putting the music up loud and slowly turining the gain up, when the subs produces that horrible sound when their up too loud you want the gain just b4 that.

actually. Wrong.

Facing the subs forward into the cabin is not going to be as loud, nor will it bump as hard. And its overall going to sound like COMPLETELY ass.

Why?

The sound waves will cancel each other out because of all the open space.

Face your subs towards your trunk, with the back of the box as far forward as possible (towards the back of the seat) for the best overall bump and sound.

dont get a bass blocker.

Get a headunit with at least 3 outputs on it with the sub capability.

My kenwood mp-7028 has it.

Low frequencies through mid-range speakers cause distortion.

I've always run a hu that controlled the sub separately, being able so adjust the volume to the sub alone is great. I have a pioneer 4900ib has hi pass x-overs for the speakers and not only separate sub volume, but it limits the frequencies to the sub as well. Bass blockers are a pain, with a good deck you'll improve your system 1000%. Also my sub fires to the rear of my hatch sounds better when the bass reverberates off the hatch door. I took the same sub, box and amp out of my truck and put it in the hatch and it was much louder. The gain is not a volume knob, it equalizes the signal from your deck to the amp. So for example if your deck has a 1 volt preout your gain would be turned higher than one with a 4 volt preout. Personally I never turn mine passed halfway. If you do decide to turn your gain up and your amp starts to get hot turn it back down, you'll destroy it. I've let the smoke out of 1 or 2 myself in my unwiser days. A nice system is when you can turn your bass to negative 15 on your deck and still knock off your rear view mirror.

Also bass is omni directional so placement isnt an issue. But reverberation is a factor.
