General Audio

i have an 08 impala with 2 12 ssd in a ported box, n i wuz wondering wut all should i dynamat? just my trunk or wut? cuz i really dont wanna rip out all my nice new interior. and will it sound better if dynmat the trunk or will it sound weaker, cuz i dont mind the rattle of the trunk, but i def dont want to loose overall loudness.

New to the forums, so forgive me if this is in the wrong thread. I'm about to purchase a GCON for my first build in 5 years, and I want to make sure it's done right. So, I'll be running a single GCON-12 in the trunk of my 2007 Honda Accord SE. I've been looking at the RF Prime R1000-1D Amp, which puts out 1000 RMS @ 2 Ohms. Feel free to suggest a better matched amp, just trying to get something for $250.00 or under. http://www.sonicelec...00-1D.html#tabs First question: Since the GCON-12 is a DVC sub, I would need to get the 4 Ohm model (D4) to get 1000 RMS out of this amp, correct? (I realize this is overpowered for the GCON, but I want to have a little overhead fo…

so i was roaming around the internet the other day and i found this sub called the emf ermagerd that says it takes 6500 rms but it wassent released yet i eamiled the company trying to find out more about it and havent got a reply does anyone know anything about this company or if this is a woofer that has been planned forever and not got done or anything about it? or google it and just check it out because the picture of it does look beautiful

I figured I only have one chance to do it right, so I thought it would be best to ask. I had planned on using my circle jig with my dremel but because of the design, I can't get the jig to sit flush with the surface to be cut. What's the best method to cut a hole for 6.5" and 1" tweeter?

Hey guys I was just interested in what DSPs you use the most on your setups? We install a lot of Audison bitONEs and bitTENs. And a much smaller amount of Fosgate 360.3's, Helix P-DSPs, and JBL MS-8's. Just curious and what do you think of them?

I am in a minor dispute here. I was looking to do a 150 trunk set up and I was talking about what I was looking to buy to a few friends of mine. One friend pipes up and says that "I can do 150 ease with 2 12s on 1k sealed in a 2 cube box".......BULLSHIT!!! SO....I am asking you guys who have done it before to please post if you have done it and how so?? i.e. ( what subs, amps, box size, electrical ect) So I can get a better idea of what kinda cash in going to be spending AND to prove him wrong.

Hi guys. Since I got my BL 15 I have no use for my Type R 12 and my buddy wanted to upgrade his system a little bit. I've done a couple installs but have no clue where to start with this. This is the system that got my into high output sound systems and now I really need to help him get things straight. He has two Blau Punk 12"s running at 170 wrms each mounted in two 5 gallon buckets. They are basically free air but when the truck is closed they actually have quite a bit of output. For what it is. Lol. Now he wants to fabricate a box for the new Type R 12 and run his amp bridged at 500 wrms. Any ideas would be awesome!! Here are a few pictures and measurements. Thanks ev…

Im looking for a clamp style meter and ebay looks like the cheapest route. Im looking at a couple and would like some opinions on which would work best. Im looking for a true rms digital clamp meter. Immediately I plan on using it on my stereo's, mainly for AC voltage and current, but later for home repair with DC voltage and current. Its not a temporary buy as I want this to last awhile. I was also looking for the one that Jacob used in his testing but couldnt find it. He even posted a link where to buy the exact one. Of course Id like a fluke or a fieldpiece but they are too expensive and Im recently unemployed. Heres the ones im looking at now. The one thats catching m…

These tweeter just came out , since I'm done with my sub setup I want to work on my front stage, I'm thinking of getting 2 pairs of these for my front doors. Right now I have mb quart components runing of an amp , it sounds good but I want it louder. So Anyone that has bought and ran these let me know how they sound and work for you.

My buddies and I were messing around with some of our equipment today and it sounds like there's no difference in output. My friend has a Rockford t1 15 d2 wired to one ohm on a sundown saz1000. Box is 3.0 cubic ft tuned 32-34hz in the back of a 02 Ford explorer. That thing bumps! Very loud and powerful. So I wanted to try the amp on my setup and my other friend wired his sax 125.2 to the t1 bridged at 4 ohms getting 400 watts. Tuned it and they sound virtually the same??? We all were thinking something is wrong with his saz1000 but could there be no audible difference between the two amps? Same song and volume same setup just swapped amps. We're thinking something is wr…

I'm always looking for ways to improve my daily driver. I am not an audiophile that can tell a whole lot about staging and imaging but I do listen to alot of music that reveals the best and/or worst of a system and I do love clean output at extreme listening levels. I have been pretty happy with my Morel tweeters and Peerless 6.5" mids with passive crossovers (my favorite amp on them to date was a US Amps USA-2000 running at only 8 ohms...extremely clean with a ton of headroom. Anyone have any USA-2000x's for sale? ) Anyway...my problems have been as follows: I burned the coils in the 200w rms Morels once already and had to rebuild them...and the two 6.5 Peerless mids…

so, i found out on saturday that after i come up with 1400 bucks for repairs, i can have my dads old car. it is a 99' ford contour. you know me, the typical basshead, already thinkin about possible woofers. i settled upon the IA-DP21 i want to put a wall where the backseat is, and integrate the box into the car. (i.e. make a box using wall of backseat, firing woofer into cabin, porting it through the rear deck) I think it would look cool as hell. Here is the amp i am gonna use: http://www.woofersetc.com/index.cfm?fuseac...Product_ID=5694 i know, not the best but i want to bump a little while saving up for a 3kd. damn, bell rang g2g to lunch. ty for feedback on this idea!

I'm going to build my first wall in the back of my 2001 chevy blazer for (4) or (6) 15" AA Havocs. I'm not looking to burp or compete really, just move a lot of air and sound good doing it. I currently have two Havoc 15's ported in a 9 cube box, tuned to 38Hz and it sounds pretty decent. I'm looking to step it up and I'm already maxed out for box size without a wall, so thats my next move. I don't know whether to build a bandpass or a large ported wall. I had a 4th order in my old truck (extended cab pickup) and it was one of the best sounding substages I've ever heard, but I don't know how well it would work in an SUV.

Ok so I am not new to car audio but I am somewhat new to high power car audio and I have a question. Current setup: 147db in an 06 eclipse 3x optima yellow tops 2x 1/0 along with a big three stock 110a alt,(soon to be 240a) Sundown zv.4 rev2 15" 1ohm (2000 rms) ts3.5k (5k uncertified) 5 cubicft box with dual 6" aero ports My question is this, I tuned my system with an oscilloscope, the voltage reached the max of my oscilloscope with ought any clipping that I could see, I do not remember the voltage but when multiplied by my clamp meter results I got around 1200 watts that sounded fine so I left it. The problem is that any time …

I have always had a decent sound system set up in my vehicle and have been driving for 11 years mostly in the area of Cleveland, OH. We have a high population of white tail, as in many other areas in the Northeast region. Deer have become a nuisance to drivers, as a collision may cause serious damage to your vehicle and possible injury, or death. I always noticed that when I had the woofers turned up at night and exceeding 35 mph, white tail deer reaction to the stimulus of sound was not to fleed, but to remain still on the side of the roadway. I decided to do some research, and possibly try to determine the cause of low and high foreign sounds for a deer to react this wa…

I've recently installed my sub stage in my 2011 Malibu. 2 sa12's on a saz1500. Box is about 4 cubes tuned low 30's. I'm not blown away by the sound. It's clean and punchy but I'm not getting the blurred vision/nose itching bass I'm looking for. My head unit settings could probably be set a little different but my main concern is the sub orientation. Currently I have subs/port facing rear of vehicle. Everything's bolted down which is why I haven't tried turning it just yet. With the box in the vehicle, back seats folded down and looking in.. Box squeezes in perfect top to bottom. Touches bottom and top. Sides I have maybe 6 inch slots on each side opened up to the rest of…

so yesterday, we were chillin, and my buddy spits out, hey i think, wait- i KNOW i want two type x's in my car, when i get the new trans. i said, should be good. now. this is the funny part. he went to walmart to see what they had, in terms of two temporary 12's(something ot listen to while he is fixing up the car) he picked up two pioneer's. only 150 rms each, and only being fed 100 each, they are easily as loud as my other friends two MTX 4500 12's off of 1000w. these pioneers are in a prefab, the MTX are in a custom. can anyone explain this to me? i know there are factors like the shape of the car, but jeez!

I would like somebody to explain to me how Mark gets 143dbs with 1 12" XCON on a khaotik enclosure and the guy from the tahoe only reaches ~156dbs with 4 18s? I mean, I know after certain point, each db requires more than just another amplifier or an extra battery, but I cant understand why the difference is so close. Either the XCON is THAT good or there is something going on with the smd subs Is it that the 18s are in a box that is not spacious enough? or is it that the box needs a redesign? I believe I remember st3ve saying each of the smd subs had 4.65 cubic feet, I think that sounds kinda tight.

Just wondering because I can't find a metering place around me and I an just curious as to what numbers I'd hit with my set up.

Ok guys I give up! I need your help to completely redo my substage. My goal for my system is to have some loud SQ if at all possible. Want 2 10'' or 1 12''. Only thing I'm keeping from my current stock is my amp which is a PPI PCX 2200. Price range 600-700 Type of music: Hiphop/ R&B Car: 1997 bmw with the fold down seats. Completely starting over with your advice since I can't do it right on my own. Thanks in advance.

From time to time I come across old drivers. A lot of which are so old, finding listed t/s parameters is impossible. So I have started the search for a way to test for t/s parameters myself. Which lead me to parts express and the woofer tester 2. Anybody had any experience with this thing ? How accurate are the measurements it provides ? Is there any other cheaper more accurate way to test t/s parameters ? Any help would be much appreciated. here's a link to the woofer tester 2. http://www.partsexpress.com/pe/pshowdetl.c...tnumber=390-802

Me and Duran are arguing about this on Yahoo. I like speakers behind my head.... But he says no. I say yes. I was thinking 4 6x9"s again. Thoughts? And also, one thing that I have never understood fully is Active vs. Passive. I will be using the settings in radio and at the amp. So, Plz explain to me in DETAIL what active vs passive is. Thanks. =) Old system

Does anyone here listen to corridors? My uncle is wanting a system and we are trying to figure out what enclosure will work best. The equipment that will be used is a 10 inch kicker CVR (2010 model) and a jl audio 250 watt 2 channel amp.. lol ..

So everyone, I got pulled over yesterday for, as quoted off the ticket. "loud car stereo - unreasonable noise. No person shall generate or permit to be generated unreasonable noise or loud sound" Such BS imo...why should i get a ticket when its nt even 6:00pm and im on a main road. Im not one of those people that play it to annoy ppl, i play it because i just all around love the bass. People with loud mufflers on bikes and even cars dont get tickets...well I have to appear in court on the 23rd now for this 4th degree misdemeanor...really, lol. Cant see the ticket being very much....but im from OH so if anyone has ever had one please let me know how it when, cost...did …
