What is the best way to have subs in the trunk? I have a coupe and my two twelves take up to much room. What is the best box to make the most bass and save the most space? Right now I have no trunk and my box is so heavy it is like having another person in the trunk.

If you're willing to give up your spare tire, you could fit a sub or possibly two in that area, using a fiberglass enclosure. Also, you may be able to fit a sub on each side of the backseat, using a fiberglass enclosure or infinite-baffle subs.

What is the best way to have your subs? Does it sound better in a box with an enclosed front and ported back or is it better to have the front of the speaker out and the back sealed off?

It really depends on the sub. Sealed enclosures are usually a tighter punchy bass and also can take more power because the sealed box helps control cone movement.

Ported hit harder but can sound a little "muddy" compared to sealed. Also ported boxes are tuned to a certain freq. below it their output drops off.

Bandpass boxes are a combination of sealed and ported. They are tuned to a freq. range and produce the most bang for the buck in that range above or below that range and you get pretty much nothing. But to get the extra output you pay the price in size. Bandpass enclosures can be really big.

You need to listen to the different kinds and decide what sounds good too you. Then you can have someone design an enclosure based on your subs.

Since size is a concern a sealed enclosure is probably the way too go.

Personally I have a single 12" Kicker Solobaric in a small sealed enclosure. I think the internal volume is like .88 cubic feet. I'm using a true 500watts rms and most people think it sounds good. It's not overpowering unless you really turn it up but even then it's loud but still clean.

Thanks for the help. I'm gonna go by my audio store and listen to the diffrent kinds. How could I find which frequency would be the best for my subs? I have two 12" sony xplod subs.

well first off you need a smaller box if you want more room


get one thats 33 inches wide or less

i had one that was for two W7's that was like 31 inches wide and it fit perfect inbetween the two rear strut towers. oh and always face them towards the back. it gives the subs the perfect amount of room/air to resonate in. in other words, deeper and hits a little harder too.

get some dynamat. that will raise the amount of sound that you hear and less rattle too.

The tuning frequency is only gonna matter in a bandpass or ported box. The spec sheet sony provides with the subs will give you tuning frequency. If you don't have it the shop should be able to get it.

So the best thing is to face them towards the rear of the car? I thought it would be louder if I face them towards the back seat? Thanks for all the help.

Try them facing both ways. It all depends on the car but usually rearward sounds better.

I'd be interested to hear on your choice and results.
I have 2 10" 600W sony xplod subs but fixed in my hb parcel shelf.
(NOTE: Parcel shelf bows under the weight).
Facing up they sound like loud speakers and over power anything else.
I reveresed them today so they're facing into the boot...sounds much much better.
Having said that, I'll probably be making a box over the winter.
