Need help with choosing some ice

[CGDoig]

Just installed my sub the other day. Looks fuckin awesome, and workes really, really well. You don't really need a box if your trunk is sealed well. Your whole trunk acts like a mediocer ported box. Here are some pics.

That looks cool from inside the cabin but doesn't look that great inside the trunk.

I'm going to get another trunk carpet and cover it with it as well. So it will be the same color all around, Clean up the wires, i might cut little holes so you can't see anything from behind except amp and sub.

Uhm...ported? I would hope the front and rear waves are separated, or you'd have a nice amount of phase cancellation. The only "vent" you would practically have a use for is a vent used to tunnel the output into the cabin, assuming you don't have ample room to accomodate a baffle on your rear deck/seatback.

Hence the mediocer.

Not trying to start any beef here, but just letting you know:

It behaves nothing like a ported enclosure. It is not efficient, and especially not efficient at the 40-80hz octave, it decreases power-handling capabilities, and there is no point when the woofer itself hands off the output to another instrument (port), nor is there any limiting whatsoever on the excursion of the woofer. The only ported enclosure it would behave like is one with a hugeass hole in it. I'm not sure I would place ported boxes with a huge hole in them in the "mediocre" category, instead more like "garbage". If anything is comparable, it is a sealed box that has exceeded the Vas parameter, which at that point becomes regarded as free-air operation.

It behaves like an IB, and nothing else.

I doubt that is sealed very well if you have the ski tunnel out...not to mention the little hole in the metal behind the seat.

I don't know guys, All i know is that it sounds great, I get lots of bass if i want it, and i can still use my trunk without using up an extra 10 lbs for more wood.

I'm surprized that no-one mentioned the "sub in the spare wheel-well" idea for saving space. If a person can sacrifice their spare, that's the best setup for a space-saver.

[Digitalwave]

Most of us need to keep the spares in the car for daily driving use, and the fact that the sound of a sub firing straight up and down is less than ideal.

I had an upfiring 15... It wasn't bad I guess.

Anyone that has the skills to pull of a GOOD spare tire setup (meaning enough work to eliminate the rattles associated with pointing your sub straight into your trunk lid) will probably be willing to give up some space for a real box anyway.

I'm using my spare tire well for my batteries.
