I was wondering what the best box would be (ported) for two Alpine Type R 12's (2011 models). I have a sealed a box right now, sounds outstanding, but they hate the sealed box.. I have the 4 door with the flip down seats taken out. Not worried about the hump in the middle as I have a board across the width of the cab. Not worried about mounting amps or caps as they are mounted under that board. I was thinking about getting/making two separate boxes to put behind each seat? Would like them to be facing up.. Any Suggestions?? I can make one or two if need be.

Thanks!

 

Not sure if you want to have space for storage or what but my plan in my truck is to have one behind each seat with an angle matching the angle of the seat.I have the 2 dr super cab and I will have one against each wall then planning on building a small seat into the top of the box. I also plan to build a small compartment to go against the back wall to house my amps and caps in.

 

I don't understand why you would hate the sealed box if it sounds outstanding... sounds like your right where you want to be. A ported box will only get slightly louder if you build it just right.

Chances are that if you were to buy a pre-built ported box that it would not be specific to your subs and would sound worse but probably a little louder. I don't know anyone who wants their system to sound worse.. You're pretty much left to building your own box to the exact specs they require. The manual states the best ported enclosure for them. If you can build or find a box that match the exact specs you will gain a few dbs and it will sound just as good.

I've always found that more power tends to achieve the best results if your already liking what you hear. sealed enclosures allow you to pour on the power, well above the speakers rated specs.

Lots of Loud Loud Bass <- Old people say what a jackass, lol sorry im 27 and I loved extremely loud bass back in the day. Now I enjoy the sound of a loud tuned system without bloated muddy and distorted bass. Too much bass is easy to achieve, its the mids and highs that are difficult to get right. I'm guess I'm getting to old.

 

i would make 1 box, find the cu.ft for a ported sub box... you got 7cuft behind your seat without going above the window.. the biggest thing is you want your port fireing twords your back or twords the floor for best sound.. ported box does hit deeper notes and pushes more pressure around your cab. give me the cuft for 1 sub and ill run some numbers and give you good demensions.

 

sealed boxes are the easiest to get right. if you have too much cubic ft then you need to take some space away buy adding blocks of wood. if you have to little, polyfil is your best friend. If it sounds to tight and punchy then add polyfil, if your subs are sounding muddy and wofty then take space away. too much boost and gain will also give you a terrible sound. I say work with what you have. little tweaks can likely fix what you dont like.
