I drive a 95 oldsmobile cutlass ciera.I wanted to get two Alpine SWR-1242D's but now want to try and get the 15" Type R's but I was told that two 15's will in a ported box will not fit properly.

Recommended ported enclosure per 15" Type R is 3 cubic feet so could I fit a 6 cubic foot box (after all displacements) in my trunk?

It will be tight, I think more that 3 cf will be neccesary, IMO.

I just took measurements.

My trunk measure about 44" across between the wheel wells and about 40 inches from the back to he front and about 17"-18" from the bottomto the trunk lid.

What do you guys think,15's or stay safe and get the 12's possibly adding two more in the future?

I did some math and a 40" x 24" x 16.5" box equals out to 9.16 cubic feet (more than enough) but if the box would sound good and get loud is another story.

Maybe a 40" x 20" x 16.5" box ported and tuned around 32 or 35Hz *whichever gets loudestwhile still playing those LOW notes and some high notes.

I would do 12"s, give them some room to breath.

That's a big trunk, you'll have plenty of space if you build the box IN the car....

The only question is going to be if there's enough space for the sound to get back INTO the car, around the box.

That is what I mean by let them breath

2 12's, I've been in this car before, and thats really all you can fit.

If you really want the 15's you you could always lose the back seat:naughty:

You can physically "fit" 15's in your trunk but that's the not important question. Whether or not it's a good idea is the question. 2 12's will sound better then the 15's. Being that the box has to be so large the 15's will create somewhat of a corking effect in the trunk therefore not allowing as much bass back into the car. Stick with the 12's.

Well, I have an Oldsmobile too.

A 2000 Alero, and I roll with 2 15"'s daily, with a 5 cube box tuned to 34 HZ. Works perfectly for me. I think they have nice turnk size for cars.
