Happy Birthday ! ! ! !

With a budget that low, you have your work cut out. You don't have to use an 18" driver. Check out some of the tapped horn threads on DIYAudio.com and see the amazing output people are getting from drivers ranging from 6.5 to 15. JP I believe the OP asked for displacement. You can get output from a fart box. Plus I believe a serious bass horn for a 15inch subwoofer is impractical in size to use in a normal car.

You'd need a relay. The relay cuts off a wire coming from the battery, which supplies voltage to the voltmeter.

Good luck sir ! ! ! Scholarships are a very nice thing

Cutting mdf is baaaaad. I've got my whole head covered when I work with mdf. Hate that dust but still need to pony up and get a good respirator. Even a cheap disposable is good Haven't looked into it yet. Only tried some cheap dust masks and they fog my glasses

Already tried, it's just not the same without the buzz Only one place to get resin and they only take big orders on epoxy resin. And a big order = way over 60gal of resin I can't even find leftovers from big orders. And speaking of buzz it was actually better today. Far cooler outside and a cooler mix.

God, this weather is getting me down. I think I'm going to overbuild the shit out of the kicks to get my spirits up. Nothing like some resin buzz.

Rained all day and couldn't work on anything

x2 More heat than benefits.

Bitch of a job to glass Prepping work took waaaay over one hour and only 30 minutes to lay the fiberglass Needs 1 or 2 more layers in some areas and then it's out to trim and see how I can attach the baffle to the fiberglass for the tuning stages.

d-poast

the fab work in that car is gorgeous x eleventy billion.

Growing your own veggies is awesome. So far we've got tomatoes, peppers, chilli peppers, onions, some garlic and some egg-plants in the garden

Having them already sure beats buying. Never heard the Iridium 3, only experince with domes is some 2" Brax Matrix, which didn't live up to the name...

Theoretically it is the same thing as going from 200 to 400 watts. In practice it will not be the same thing, especially at that power level. There are lots of things that can mess with the theory.

Dome mids, bleh Try some Scan 12m's. Should sound wicked ! How is the stage height ? In mine I got the driver's side to image almost on the dash, didn't play too much with the passenger side though. Funny coincidece, I've just finished masking things up and getting ready to lay the first layer of fiberglass in the kicks in my cherokee Oh dear, more and more coincidences with the sq system. I'm only lacking in the spl department

Just heard about it on the radio. I'd go out of town, but meh

Do not mix up diffrent subwoofers, either use the dual 1 or dual 2 or get 2 identical subwoofers. Look up some resistance calculations. Basic formula is : 1/r = 1/r1 + 1/r2 for parallel connection of loads r1 and r2. r = r1 + r2 for series connection.

Budget ? Electrical upgrades ? Wiring possibilities for the subwoofer ? These are all details we need to know to be able to recommend something.

This ^ doesn't make sense at all. I've read it 3 or 4 times and I still can't understand it. All the power in the box ? You never hear the rear wave ? Essentially yes, it does sound weird but it works... In essence you are putting all the sound in the enclosure, and you really won't hear much of it, the sound is meant to come from the front of the cone not the back. The rear sound wave never leaves the enclosure, is that what you don't get? Sound is not meant to 'come from the front', it is meant to come from a perturbation in the air, which can be cause by a cone moving back and forth, 2 wings flapping, a door beeing shut etc. The subwoofer is not a fan or hose which moves air in one direction which is what can be understood from your explanation. The cone oscillates back and forth and produces sound. It does not shoot air forward. Or backward. Not air, sound waves. If the sound never leaves the enclosure then why wouldn't you just use a sealed box all the time. Because there is no release of pressure in the enclosure, there is with a vented enclosure and they are more efficient because of it. There is no 'realease' of pressure in a vented enclosure. The vent acts like a sound source because the air in it is excited by the waves in the box. More reading material : http://en.wikipedia.org/wiki/Helmholtz_resonance

Sound waves are transmitted by oscillation of air mollecules. http://en.wikipedia.org/wiki/Sound And http://hyperphysics.phy-astr.gsu.edu/Hbase/sound/soucon.html#soucon Sound waves are not something magical and independent of the medium.

They connect the water pump to the heater core You live in AZ and need heat?? It's extra engine cooling Turn the heater to max and cool the water in the heater core
