Subject: custom boxes for mitsubishi lancer
Date Posted: February 12, 2004 at 6:03 PM

i am going to be installing 2 15" subwoofers, but i need to make some custom boxes up due to the limitations of the size in the back of my car, which is a mitsubishi lancer, the subwoofers im getting are going to be from the fusion range and i will probably be putting 300-400watts RMS through each of these most likely at 4 ohms each

my question is, how can i work out the exact dimensions i will need for a 15" subwoofer, the calculators on this site really dont seem to be specific for particular sized subwoofers, i pressume the size for a 15" box and a 10" box will differ

What kind of woofers are you planning to use?  Every woofer has different enclosure requirements.  You will need to look up the specs on the ones you intend to use.

my old subwoofers were 15" but their RMS was only something like 150w some cheap and nasty brand too, but they sounded good :)

So, you want 15's because you don't want to change the box? Tell us about the box, what size is it, is it sealed or ported?

sorry i think uve misunderstood me due to my vagueness..let me explain

i wish to make a custom enclosure for the back of my car so i can get to my spare tyre without having to pull out the boxes..being 15" subs and all they are very very heavy to have to lfit out 2 of them..im wishing to make an enclosure that will go around the surrounding tyre well so i can still get to my spare tyre without having to pull out the boxes

i purely want 15's because they are better than any other subwoofers ive had, and these were cheap and nasty ones

the box i have for mine were originally designed for 12" subwoofers but i had the holes redrilled to suit 15" subwoofers

Are you trying to annoy the outback with bass or are you after sq? Do you want the subs to play deep with authority? The box is the most critical aspect of your sub sustem, it will make or break your sound. If you put these big nasty 15's in a box, you're playing russian roulette. Your better bet is to choose a sub system that works within the confines of what you have. What amp do you have to power the subs? More info for us is better as my crystal ball need to be recharged and Dyohn can't use "the force" right now.

im after alot of bass but no bigtime distortions so yes..sq and volume

the amps i am going to buy will be whatever it takes to do the job...

i was also going to run splits so one amp for splits and one for subs

i dont have the amp information on me right now but i think its 500w rms or something around there

my previous subs before the 15" i have now were 10" subwoofers and they struggled with SQ and bass at high volumes, where as 15's seem to have no problems at all...12" i really dont know about..but i know 15" sounded good in my car even without the right sized box

my original question was basically how do i calculate the sizes of the boxes needed for 15" subwoofers, are there any other calculators on other sites that do the correct measurements depdning on wattage, size of sub and so on and so forth?

Do you have a budget for your subs? I and many others can probably get you into something that will do what you need without the large size subs and the resulting enclosure. I've got to head home in a bit, so I may have to respond later, post up what you can do and what you don't want to do and the reason's why.

i would prefer to stick with fusion audio for my whole system, i dont wanna mix and match components particulary

anywhere up to 500 dollars (aussie) on each sub but id prefer they were fusion

If your looking for SQ your not going to find that running with fusion and also running 15's. You will be better off looking into some eclipse gear... beautiful SQ and go loud as you want them too!!

i dont exactly have a good range of stuff to pick from. as i live in the middle of nowhere, i can get stuff like sony and pioneer....which id rther stay away from for prior bad experiences with them..eclispe..well never heard of it...this is australia afterall, the best stuff i can get is fusion..fusion has had alot of good reviews and stuff, plus ive heard some fusion systems myself and was impressed

just keep in mind i live in australia and as far as brands are concerned i cant even get my hands on half of them unless i go internet shopping which id rather not

Nedgeworth can probably source out the Eclipse gear for you, he's one hell of a lot closer to you than I am (kinda cold here now - roadtrip?). Mixing and matching brands gives you the best possible combination of sq or spl or build quality etc. No one company makes the best of all items. Open your ears to other options and those options will do you no wrong. Fusion is a good brand but there is certainly a lot of other brands that are far superior, Eclipse being one of them. Keep asking questions, you'll get more answers. Nedgeworth, can you find him Eclipse gear?

Well where abouts in this beautiful country are you? (I'm from Queensland myself) If you wish too look at getting gear posted too you i've had great success with a company in NSW. https://www.fhrxstudios.com/

These guys are great. They don't just sell you your equipement and that is that. They will help you will absolutely anything you need.

We have all the same brands alviable to us over here as they do over in the States. They just get a lot better value for money than we do!!
