few questions

[ladi3sman55 0]

ok first off i have 2 maw 15's in a sealed box.. not the loudest setup but it sounds damn good! anyways i have a few things i have been thinking about trying.. 1) 2 external aero ports (tuned to 30hz)(size? amount?) the box is 5.7 cu ft (inside the wood) not sure o sub displacement.. and option 2) i just use one maw 15 and port it to 30 hz..

which would get the loudest?

ok and just today my subs quit playing the beat of the music and had a really faint thump that kept going.. the speakers in my car were still fine. im thinking its something with my rca's.. also b4 this happened my sub would go into what i thought was protect mode. when i woud start my car for the first time it would seem like the amp had to warm up or something b/c it would cut out occasionally (usually on harder hitting bass and long notes) i thought mayb it was getting 2 many volts b/c it would go away after a while but i never really figured outwhat was causeing that..

so any help on those problems would be great.. (btw amp is disconnected from battery) o and the faint thump was at a consistant rate and would play when ever the car was started.. didnt matter if there wasnt a song playin or if the faceplate was off or anything like that..

Subs don't go into protection, amps do. Sounds like your amp turned off & on & you have a suspect ground in your system, likely your headunit.

Also, you would be much louder if you faced the subs to the rear of the car.

Two 4 inch diameter aero ports 10.25 inches long will tune the box to 30hz.

yeah i know that subs dont go into protect.. that was a typo.

and why would it be louder facing the other way? ive heard this b4 but i dont remember the reasoning behind it.. the only reason i faced them the way that i did was to make it easier on my self when installing the subs.. i had to screw them in in my car and the baffles were chitty so they wouldnt go in right. i will think about turning the box when i redo the baffles and brace the box..

also any views on 1 sub in a ported box vs 2 in a sealed..?

I'd prefer the two sealed, but that's just me.

Cliffs: When you face the subs towards a hard surface, it will load (reinforce) the sound wave.

I also say this because of experience, you won't need to port if you face them to the rear.

I will second Jim's preference.

i think the amp is faulty.. i read some of the manual and they said that is what happens when there is a problem with it.. so i'll send if back and hopefully just get a new one.. hopefully they are fast with their shipping!! i'll see if i can get it shipped off tomorrow!!
