I have a 99 chrysler cirrus that I wanna put my 2 15 in l5s in. I was thinking they would fit if i took off the back of my back seat because my seat can pull down. I were to extend the box into the back seat would i be able to get the right dimensions for a vented box?

Would you be able to measure your trunk and post the max width, depth, and height that could be used by the enclosure?

This ^^^


Also, Kicker square subs like volume. So an enclosure for 2 15s ported will be rather larger(lager then your average dual 15" enclosure).

its 37.5 width and 17.5 for height and the only thing i dont have measured is the length but if i take the back seat out i should have around 40 in to work with or so.

exactly...you are probably looking close to 9 cubic feet after all displacement is taken into account.

9 cubic all together? I was thinking more like 10 to 12 cubic for both with port?

9 cubic feet AFTER displacement is taken into account...so it would probably be close to 11/12 after port/drive/braceing is taken into account

This should be possible with the back seat taken out though right?

If you build the enclosure in the car.

Not sure losing the back seat would be worth the output you will get though. I would suggest selling them and getting something to fit better with your application.

Lets take a look at the measurements when you get them and go from there.

Good point...The depth of the enclosure could become so great that it will be impossible to get it into the car itself.

So i measured it and here it is: 38-witdth 64-length 17-height. I could possibly get 18 in for height but it would require me cutting off the support for my back seay(which I wont need anyways since I'm taking my back seat off.) Any help on this box would be appreciated. Looking to get a big vented box built for them. And I would be willing to build it in the trunk. Thanks in advance.

I was also thinking though, could I just cut a piece of MDF to fit the back of the back seat and basically wall off my trunk as a box and have them facing forward? Or would that sound like total @#$!?

Are you ditching the back seat? If you are, then why build in the trunk?

Yes but I'm building the box myself and I figured it would be easier to build it in the trunk and because I don't have $800 to spend to wall them lol or I would.

If you build the wall or half wall on your own it won't cost $800 or what ever to build. Just more time and effort, and it will look much better then other options you are considering at this time.

Personally i would just use one sub or get something different all around that will work with in the limits of your application.

I am wanting to trade these for 2 12 in l7s and build a good box for them if I can find some l7s. I owned a pair of 12 in l7's before these and I loved them. Would that be a better option do you think? I think 2 15's would just be a hassle to build the box in such a small car.

I'm looking for spl here thats why I went with these 15s. I figured in the right enclosure they would slam... but the main concern is building the box. I would rather get 2 12's though.

Personally I would get some nice round subs lol.

You may be able to fit the 12s in your car. At least it would be much easier then what you currently have.

A car like yours and SPL when in the trunk do not really go together lol.

What are some good subs for spl that will keep up with the L7s for the same price? I'm open to suggestions to other subs... I have just personally owned all kicker subs and I love them so I don't know what other subs I could look at? I want them to hit real hard and I want a vented box for deeper bass.

Your best bet is to set a budget and go from there. Depending on the power you want to use and the budget there are lots of options.

Remember though SPL is only a number. In order to achieve a decent number with out a tone of work is higher tuning.

If you are talking about just being "loud" rather then SPL then that is much different and a lower/average tuning will net a decent result for that.

I had 2 12 inch l7s that I loved that were extreamly loud, hit real hard, and they went real low and would shake everything. Thats what I'm looking to get again.

Ah, yea that is not SPL. That is just being "loud" which is more subjective then anything.
