hmm..i have 1 mtx 12" 6000 and i was wonderin whether i should face my sub through the center armrest, or just place it the usual facing the back of the trunk. what are the advantages and disadvantages?

 

The advantage of putting it through the hole is sound quality. You will have a more accurate bass response time because it doesn't have to bounce off the rear end. The disadvantage is SPL. Probably at least a couple dB's. Either way keep the ski hole open.

P.S. Most people can't tell the difference in accuracy but almost all will be able to tell which way is louder.

 

Face the sub towards the rear and keep the pass-thru closed (it doesn't make any difference).

 

I agree with Micah95GLE. Whether you have the pass through open or not it doesn't make that much of a difference. I have my sub facing towards the rear of the car.

 

I can tell a difference but the thin steel which seperates my trunk from the rest of the car is covered on both sides with damping material, wrapped in fiberglass, partially wrapped in carbon, and the back side covered in 3/8 inch foam rubber(same type as used in mousepads).

 

I felt a major difference with the armrest open than closed. More Bass inside the car and less rattling. I have two 12's in a sealed box facing the trunk and placed more towards the opening than the backseat. If you leave the armrest open you'll fel a difference when you pump it loud.

 

That was a question I was wondering about also. I leave the ski hole open just because I have my amp mounted right inside there so it just looks cool when its open. Also I have a dual bandpass box to theres alot of bass no matter what

 

Face the subs to the rear of the car, this will give you clear bass and the trunk will act like second enclosure. It will make a big difference in sound Quality.

 

I have 4 JL Audio 12's and I have them on the sides facing each other. It rocks. I used to have 2 12's facing the trunk and it sounded good, but it is definently a mark of improvement when they are sideways. I have a board over my armest opening that I put there to mount the amp.
