SPL & SQ / Fabrication

This post is going to be a little bit technical, but since most of you are more "technical" than I am, I'm sure you can handle it. I need help setting up my amps, and more specifically setting my amps' crossover frequency cutoffs. I understand if nobody wants to take the time to reply, but I'll just throw all of it out there. First, my setup. Some of you have probably seen my installation log (and my sig), but I'll lay it out more specifically here. I will be installing my amps very soon, and need to set all of the dials before I screw them into the amp rack. Amps JL Audio 500/5 (for front speakers and sub) JL Audio e2150 (to drive my rear fill only) Speakers Fronts:…

I have a Acura Integra Integra GSR, a ED 9.1 Amp, and a RL-P D4. I'm competing in the IASCA competition at the Nopi Nationals this year in Atlanta. I need help designing a box. People have told me I need a big box with alot of port area, and some people say I need a small box. So I'm confused and have no clue what to go with, I can't seem to find ANY information about any SPL box designs anywhere, out of a number of forums. If someone could help me, even with a roundabout guess of how big and how much port area I need, it would be GREATLY appreciated. I believe the resonant freq of my car is around 58 Hz, which I'm told is a good thing, I know how to tune the box and ever…

I plan on doing some dynamat here soon, would it be worth also filling my panels and/or doors with polyfil? What effects will it have?

Okay, Elderado told me that in my car, i have a gas tank between the trunk and the back seat. I actually think that the tank wall is my trunk wall. Anyways, Odds are good that I cant get wire back through any cracks there.. So, where do I put it? <pics tomorrow when its daylight> So, I was thinking maybe right behind the drivers seat in a nice sealed box with some plexy glass over the top so it doesnt get stepped on. Either that *not behind the passenger seat becaues its always moved* or I can stick it in the rear deck. Like, I could be able to drop it inbetween the two rear speakers? But I would need to check the space between the deck and the gas tank. Als find ou…

Ok guys i have a 2006 charger. It supposedly has a 180 amp alt in it. Over the past few weeks i have done everything i could possible think of to get rid of this alt whine. Change grounds on the HU and the AMP.Changed RCA's. Ran an isolated ground to HU from the battery. Gave the HU an isolated power to an external battery. Seperate ground to the alt with the stock wiring in. New alt power wire with the stock wiring as well. Took the serpantine belt off the pully's to see if there was any catching in the alt(no catching nor was there an play in the alt shaft). Went and got the alt tested today its a good alt. Got the battery tested and its a good battery. The only time th…

ok my friend will build me a box in his wood shop but i need to get him plans. SI 15 MAG, ported. what do you think of the aeroports? is it worth it for only $25 extra? most people use 2 of them at $12 each. power will be a hifonics ZEUS 1000D 1000@1ohm it is a lexus 2002 es300. should be the same as the new camrey. people have put 2 15 in there before with a almsot bent box. i only need 1. the red strap is what i will be using to hold the sub in place, i would also love there to be ehough room to put my trunk battey next to the box. it is 6.5 inches wide demetions are THANKS FOR ALL THE HELP I AM FINALLY BUYING A SUB TO FINISH MY AUDIO SYSTEM AFTER 2 YEARS!!!!!

can i make the wicked one to house a single 15"? is so how??

Since soon I will be installing a new sub in my truck (if i can ever get in contact with nick at IA) so while i have the 180lb behemoth out of my truck i figured I'd slap the leftover second skin somewhere. Im looking for the most quiet and the most potential SPL gain. My doors have 1 layre on the door skin and 1 1/2 on the door (didnt botehr putting a second layre over the window acess gap incase i ever need to acess the window) I have 2 on the back wall and that helped a LOT. It went from slapping my bedliner to maybe 1/2" of movement full tilt. I feel much more comfertable upping my SPL now that my back window isnt dancing...as much. The floor and firewall would proba…

i need help in making a ported box for a re xxx 12" v4 for a vauxhall astra sxi 52 plate could any one please help me

looking to buy a saw blade for my circular saw to cut my MDF. i was going to have lowes cut it, but i can't quit worrying that they will mess it up so im going to do it myself. i have been told to get at least a 40 tooth carbide tip blade....i am only going to use this thing once so i dont want to put a lot of money into it. i was thinking getting a higher tooth count blade, just not carbide tipped. i was thinking like a 120/150 tooth blade....would that work well? is the carbide tipped that big of a deal?

Me and smokedog will be hosting a show in bluefield wv at an autozone. We will have it at the end of sept. To space it out from the other shows thats happening up here so we dont get burnt out on it. Spl will have 5 classes still and we are gonna do sq as well. Door prizes will be supplied by Autozone, it should be a blast. But spl and sq will be happening at this show.

So I have my normal starting bat up front and I'm going to put an additional battery in the rear of the car near the amps. My question is should i run a fuse near the main bat to the 2nd bat as well as in between the second bat and the amp. All in all I don't think an additional fuse would hurt anything and if they power wire ever chaffed through I think I'd be really glad I had a fuse there. any help

Its been a while since ive been on here... but i need some help... I'm building an enclosure for my new car (02' focus ZTS) which will house 4 10" woofers firing towards the rear of the car at a slight angle with the deck lid.. (ie 35-45*) question one... is this going to cause a lot of cancelation? question two... i want to build a seperate air chamber to fit the spare tire well... and connect the two chambers to increase my overall air space... will doing that actually do anything for my airspace considering for now... the box is sealed? thanks for any help -AcId-

Would it be a good idea to cool your coils down to less than 0*C before your SPL run. One of the ways i have thought about would be to spraythe duster cans upside down int the pole vent. Only problem i can think of is if you got alot on the spider. Lower temperature means lower resistance which means more power.

I want to mount a Double DIN unit in my 1.5DIN dash opening. Yes, I know it is 1" taller, and I know I need to be doing some modifications. I can handle that. My problem is, the unit I want to use does not come with a cage. http://www.crutchfield.com/S-qehudI3MTzg/c...550&I=257AVX706 So, I need to fabricate a way of installing the Double DIN in the dash without use of a cage. Perhaps I can use an already existing kit... and mold it into my factory stereo trim piece. The whole bezel over the stereo and HVAC controls comes off. And use a kit like this one: http://www.scosche.com/scosche_caraudio.as...&ItemID=HA1566B Mold the kit right to the bezel, then slip it in…

If i where planning on useing external ports for my SPL set up (probably a pair of 6") to decrease cancelation and turbulance would it still be a good idea toconjure up some type of brace for the port? i would assume so but im not 100% sure. Keep in mind i want to easily be able to change the length of the port not only for trial and error testing to get the highest score but also so i can give it a daily tuning for the ride too and from the competitions and so i dont have to lug the Ava out of and into my truck every other weekend.

well, after a long and horrid search for a sub, i finally purchased a near new eD 13Ov.2 (bought in Jan. '06). now, its time to design an enclosure. i know eD has 1 ft^3 for the recommended but i was just curious if there was anything better, as it shows 1 ft^3 for the Ov.2 and Kv.2. obviously, looking for sealed right now, not going ported YET. i want it to hit hard, hit all those double bass kick drums hard, want to get as low as possible, and decently loud. oh yea, going to be putting 400 watts @ 4 ohms to it. no plans for amp expansion right now. im looking for a cube, not a rectangle as well. i figured up on rockfordfosgate.com and a 13.75x13.75x13.75 cube (external)…

well the time is aproaching. '06 seasoon ends in 4 months and my senior year (and project) starts in about the same time too. I will be running in Street B, equiptment is as follows. OEM TC9 w/ Death Penalty Recone 15" Starting the season with a BX1205D and as i earn money (or if i save nough over the summer) and then i will have around $300 for another amp. I have a 2000 Mazda B3000 Ext Cab 4dr, Will be running either an Optima Yellow top of Blue Top. Set me a goal. I'll have a sticker made up saying "Powered By TeamSSA" and put it across my back windsheild if i hit it. My GF's Uncle used to be a part of Team Kicker and before that Team Roxfor Fosgate. He said if i wa…

For the past couple of months I have been playing around with imaging. been reading everything I could get my hands on, even picked several brains along the way. I started my project with simple goals in mind. But after listening to others systems, as well as my own. My goals keep getting raised I built the kicks allready. Temporarily using a pair of $1 crunch midbasses ( I love yard sales ) and a pair of large format PE silk domes. Simple inline crossovers. powered by an rf 200a4. To my amazement, and a few others. The sound was rather nice with no processing what so ever. So my goal has now changed once again. I was originally building towards a single seat soundstage…

just starting to figure these enclosures out a little. any one got any info.

alright i have a 2001 honda accord coupe, and am looking into buying a new ride. im not sure whether to be looking into another trunk installation, SUV, or hatch. I have a diamond audio d915d2, a us amps AX1000de amp, alphasonik components with a us amp merlin md41 powering them. i am looking for basically a realiable wehicle that will be the best for a LSQ system. looking to pay around $20k or less, or if i should stick with the car i have now. dont have an enclosure yet, but will build for respective car. (if keeping the accord i will be making a fiberglass corner enclosure), and i may also be doing this for any other car i may purchase. something sporty, and that…

Currently I have four Kicker Comp 15s doing a pretty good #, really pounding for a street beater on such a low budget. In the vehicle, we have room for a 4th Order Bandpass. I used a calculator from www.carstereo.com to design one but doubt its accuracy. Can anyone aid me in designing a 4th order bandpass, or link me to a site with theory/equations for one? Simple calculators are hard to trust w/o knowing the math behind them!!

Anyone know where I can look at pics of pods? I'm having some started today for my jeep. I'm not building them myself. Is there anything I need to be aware of or tell the person making them? I don't know jack about them. I'm installing my Kicker RS6.5 component set in there. I'll probably mount the tweeter in the co-ax. Any comments, opinions? Me competiting in db drag street class means I can't have anything large or alot of glass on my door.
