Inverting a sub should have no effect on the musicality or longevity of it.

Welcome to SSA

And you didn't visit me

Spec's will be dependent on the sub woofers you choose to use. My dimensions wouldn't do you any good b/c I was getting rid of the spare tire well and fiber-glassing to make everything as stealth as possible, but sadly I ran into job issues with this economy... So it never got built.

2 18"s would be a stretch, I own a 2008 Jeep Patriot and I've mocked up an enclosure for 2 15"s... Sub's up port back... I wouldn't be too worried about the rear tailgate, but you will need to put something between the license plate and the tailgate (i've always just cut a piece of dynamat or second skin and stuck it to the back of the plate, but there are only 2 screw holes if I remember correctly so getting that back plate to not vibrate is going to be a pain.) If I were doing it in my patriot i'd probably go with either 2 12" subs or 2 15" subs.... I would love to do icons on a 3500d (sundown saz3500d) but I think i am going to go a different route instead of beating up another car (especially one I'm still paying on).

If you lived here i'd get you a job.

Bad RCA, loose wire, blown speaker. Short somewhere.. rca's not grounded properly, bad y connector... Amp is bad... those are the general ideas.

Woot, I love knowing that I do the same job you used to do Tirefyr

Nope. Mids should be on a "channel" or more specifially a pair of channels. So: Left Mid: 1 Right Mid: 2 Left High: 3 Right High: 4.. So your low pass/high pass filters are affecting the right speakers.

You will most likely never see wave cancellation within a sealed box in car audio... The boxes are just too small considering sound waves are measured in feet, even 1/4 waves at frequencies sub woofers are producing.

i have yet to buy a DMM lol but i dont think they'd be blown..they're brand new.. i checked all the wires and everything is connected, solid. but if they were blown, doesnt that make them sound horrible? not quiet? Depends on how they blow... and where the speaker fails, sometimes they just die and you never hear from them again

Are you sure all of your speaker wires are hooked up... A loose wire would cause a change in impedance, not to mention a speaker not operating... Also make sure no speakers are blown, check the impedance at each coil.

They also make void free baltic birch.

IT's simply amazing how far we have advanced in so little time. You can thank the owner Volvo for the seat belt and airbags, his wife was horribly injured in a car accident which in turn motivated him to search for safer ways... The real scary thing is to see how far we have advanced in just the past 15 years alone... As an auto body student, we had to study crash videos.

If your box may ever get wet, make sure it isn't mdf... it baloons and looses all structural integrity.

Yea, definitely a good start to figure out why it's going into protect. Don't ever buy 2 amps to power one sub unless you are strapping.

I have the old version of the one you linked, except mine was the pro model, but mine is from 2005, the car doesn't exist anymore, but I have the alarm for when I build another.

my friend has a compustar alarm system in his tahoe, i dont remember which one exactly, but the alarm would always go off randomly after he presses the lock key on his keychain Just sounds like he needs to adjust the sensitivity... at the most sensitive settings I've seen the wind set mine off. Other than that my "random" alarms were just my father or friends screwing with me.

I would buy that compustar, 1 mile range and an LCD key fob... Just ask them to do hard wired connections instead of t-taps (or just ask them if they use t-taps) I've seen countless alarm/starts fail b/c of t-tap connections, they aren't built to handle any decent current before melting.

With the power you have, I would definitely do the Icon's... Flared ports can produce slightly more output when done properly, but not that you will be able to "hear" it as much as see it on a meter b/c of the exponential nature of spl. Is this the first box you will be building?

I don't have any experience with viper to comment... The shop I used to represent used Compustar/Directed and the occasional Varad piece b/c of the flashy lcd screen.

I will say this, if someone wants your stuff bad enough, they will get it alarm or not.
