So, chew, what would happen if you say in your car while doing these tests? Well If not wearing headphones you can definitely do damage to your ears above 145. Some competitions require you to be outside the vehicle due to safety concerns, those with weak hearts have been know to have a heart attac...

Awsome you should take some pics. Want to come help me with my project that i've been stalling on for quite some time? This is the results of my mx-3 dominating the North East circuit for seasons 06 and 07, I took a break this year, money has been tight. This is not all of them some were on loan to ...

Batteries are tough. I had a narrow box ( Memphis MOJO's don't need alot of space for SPL, 4' cu ft total volume ) Mine were mounted next to my box drivers side. Amps were mounted on back of box. Problem is the 2600 kinetiks are rather large and if you place them on the floor behind the seat they ki...

drivers side, and ditch the spare tire. The spare tire well is sort of key in this car, I still have no clue how it happens but with the spare tire removed and the well left uncovered its a 2 db gain minimum. I even went as far as to use a Dry Ice fogger in the car while burping a note, You can see ...

For the "52" hz box don't use any internal supports, instead double layer it 2 sheets mdf for each side, also you can learn from my mistakes, over size it a little so that you can fiberglass all the corners inside the box and round them out giving the air pressure less resistance and bette...

Yep thats perfect if you run into the box being a little to much volume you can just make it narrower, it won't effect anything.

yeah the sub is very beefy... will be feeding it 3000w rms + Can i remove the back seat cause that sub works best in a 4cuft box after sub and port displacement.... I dont think by keeping the back seat in there will give me enough space.... By all means remove the back seat. If its going to be tha...

chew*, I think you lose most people :) Yah that comes from being in the spl scene to long, It tends to make you take a more technical approach, takes alot of fun out of it but after building X amount of boxes for a car the technical approach can cut it down to maybe 3 builds. When you build a wall ...

That will work also but just continuing the original port to the right will work better. I don't have a program like that but i'll do a quick and dirty one for you. If you end up running a preety hefty sub however you may have to use the design in your second picture to allow for the magnet/motor of...

First off up fired, ported rear will be an epic fail in that particular car. The box needs to be mounted tight against the back seat and not extend over the edge of the spare tire well. I't look like your rolling ported so............the port will need to be fired rear as well as the sub. It looks l...

It's most likely something to do with the alternator/ idle speed, lower idle lower amount of power the alternator generates. Your battery may be tired if this is the case.

I love the sound of 10's, used to run 6 old school 10w6 in a CRX sealed.......150db+ and clean to boot. Then i got into SPL, JL isn't as efficient in those applications and anything over twice the rated power scorches them, I ended up with memphis which i put quadruple rated power into and they play...

I agree, simple seems to be better. I have a nice box I made the stretches most of the way across the back of the hatch...no its not the best design since its alot longer than it is thick, but it fits the car well and still sounds nice. Chew, would more power to a sub increase the SPL that much mor...

I think they are designed on the same premise of a bazooka tube.......Bazookas are impressive depending on the acoustics of the car, toss them in a typical trunk and they are an epic fail, toss them in a typical hatch ( rx-7 ) and they sound impressive. That said just because a "setup" ban...

Thats exactly what a passive radiator setup is designed for. You have an actual sub, then you have the "radiator" basically an unpowered shell of a sub. etc no magnet its just a suspension sytem so to speak. Only company that I know still does this with car audio is earthquake though, its ...
