For 500 you can have a well around complete system.

Looking at watts is worthless to determine whats "BEST"

 

[96dreamss]

ur right thats was jus a thought when he said a 18"

It is a Solo X not L7 That 10,000 watts is for burps not daily. They only have a 3" Coil and a 3" coil can't take more than 4,000 watts daily and that is with clean unclipped power. I have seen those Solo x's blow off 2,500 watts. As far a 2 18" BTL or any other 18" you could definetly fit 2 in the trunk. I was going to do it. The only problem was even with a hole in the rear deck for air to pass threw they will tear your trunk apart. With my one 18" BTL with port and sub in the trunk it ripped the sheet metal by the hinges on the trunk lid and on the 1/4 panel by the tail light. That is why I built a new box with sub and port sealed in the rear deck. And there is no way to get 2 18's and have enough room for port area sealed in the rear deck. So I haven't done it. So yes you can fit 2 18's in the trunk. But it is going to trash your car.

Yeah I plan on doing 4- 15's in a 6th or 4th order bandpass.
Well you could fit 6 like this-

u could do a 4 order by buying (2) 2 15" seal box. get one sheet of wood at home depot. cut it in half. then put one on the floor and put the 2 box of 15s on top as far out as possible to the bottom wood edge. then put the other half on top of it and get another wood for one end of the side and you'll have seal/ported box design where the bass will travel to the front. IMO i still suggest a simple port box is the way to go

And the passband and gain would be? There is more to a 4th order bandpass than a sealed and ported box.

Exactly what I was thinking.

I second that statement, guess i need pics to better understand

 

[defdaboss]

i apology for not explainin things better but i was told from a professional box builder when he saw my set up. i dont understand it completely but i understood the result. if u look at the picture

it's more like a seal box back there with everything shooting forward to the cabin. hard to explain but picture a seal box installed. inside the box nuthin leak making it a seal box some bass are trap inside the box. because of this it give u more PUNCH when the bass hit. now using the FRONT side of the speaker (not in a box) you take advantage of it and create a port. only difference is it's not OPEN AND SPACEY like the picture provide. it has some sort of TUNNEL to create the bass coming in front of the speaker to create something real low as 35hz. think of a bandpass box . just like that but the OPPOSITE and deeper port..

in other word.. the inside of a port box would be the outside of a seal box.

anybody catchin on that could explain this any better than me?

That picture is a 4th order bandpass. What I was saying is you can't just take some sealed box and attach a ported box. In a 4th order BP the ported section is usually tuned really low like 27-30hz to pick up where the sealed boxes steep lower end roll-off. The sealed section is used to pick up the higher frequency that the ported section pick put out. And if you build a 4th order BP right you can get a flat response from 25hz-85hz(passband). And if you just if you just put some boxes together you will get a passband like 50hz-125hz.

it doesn't help that I'm drinking... but wtf? I'm pretty sure the one 18" in a ported box will suit his needs just fine as long as the box is built right for the sub.

 

[killerzracing71]

Man screw all this crap. Dude just make a large ported box with a lot of port and a long port. So it will be tuned to below 30hz. Find a sub with a low fs and call it a day. All this bandpass box it a not a small task and if done wrong is worthless.

If u want a real box look up 1/4 wave enclosures...........

Just stick with a ported box tuned low man....... damn..........
