So I bought a Tantric HD 12 d2 a week ago and received it yesterday. Today I went to put it in my 2.5 cu enclosure and I am having a problem with the sound/voltage. It doesnt drop ( to maybe low 14s) and something is definitely wrong. I had a problem similar to this last week when I realized my coils on the mayhem were toast. Voltage drop with zv4 was to around 12 volts. The way it is playing seems as if it wired very high. What I did: -Checked coils on sub (read 2.4ohm each) -impedance at the output terminals is 1 ohm (car off) -o-scoped the rca's and output voltage (clean) - free aired the sub and notice no coil rub at all (seems as if not getting full power) and it s…

I just hooked up two 12" dual 2 ohm Ascendant Audio Havocs powered by a sundown audion saz -2500 amplifier in my 2004 dodge ram quad quab in a bassforms box. Before this i had two 12 inch kicker cvr powered by a cheap 2500 watt ssl amp. The problem im having is first i think one of the subs is busted, it sounds like a voice coil it rattles as if its not tight until you hold the sub down, when you push on the dust cap off it it rattles profusely so i think i may need to send it back. My second problem is my setup is no louder then it was before. i mean its loud but i expected it to be a decent level louder then it was. I have my subs hooked up to produce a 1 ohm load. My …

Which one should I do.... I have a SAZ3k and power to back it up.... I already have a box built to seven cubes tuned to 33hz that I was using for my BTL but I offed that to get a new sub. Give me some input!!!!!!! A few more things This is going in a 96 jimmy with 3 layers of second skin and for power as of right now we have a 300amp iraggi alt with the process of building a bracket for the 2nd alt I have sitting here. Batts we have a yellow top under hood and a bt120 shuriken in the back. I have 3 runs of 1/0 monster cable 2 from the alt and one connecting batts. I have 6 grounds of 1/0 1 that goes from that batt front to back and other 5 go directly to chasis. A video …

http://www.danleysoundlabs.com/danleyport.asp?ID=33 The most powerful semi-mobile subwoofer in the world. Can create tones of 94db from a 15-20hz sine wave, up to 250 meters (820ft) away. Can play 15hz tone at 140db 24hours a day 7 days a week without electricity due to a generator it has inside. 40 15" subwoofers and 40,000 watts self generated power.. Pretty impressive. I found it pretty interesting.. Anyone heard of this company/ subwoofer room?

http://www.simpac.com Eh, I don't know what to think. Hype? Sure. Reality? Possible.

So here is the scoop. 02 Silverado with older Pio Premier, H701, C701, Sundown 100.4, Sundown 1000D, big 3 with all 1/0 (pos to alt, neg to frame, neg to cab). Had some trouble with some tweets blowing (Link to that thread) and narrowed it down to the Sundown amp. Quote from previously linked thread below Had it sent to db-r they sent it back after they replaced some things. This is what db-r said... So I got it back and during the re-install I installed a Alpine W505, added a HU ground to metal in the truck. For the amp ground I ran a bolt through my cab with 1/0 on one side to the distro and 2 2gauge strands on the other side (had it so I used it). The 2 gauge str…

Hey guys my girl friend is asking me to get her a little bass in her car but she wants to keep everything stock! which i am very cool with! the car is a 07 hyundai elantra and I have never did an install where everything is stock so I thought i would ask how do I do did it first of all and what I will need. Now i think i will need a LOC (line-output-control) is this true? I have never pulled her dash apart and it looks crazy to do. so if anyone has experience with this or knows something that i don't please let me know. next i will need to rig of a remote wire... i was thinking of just using a switch or is there a better way to do this. thanks in advances and if anyo…

** Coles notes: Very hot today, as soon as I turned up the volume the 2.600 amp shutdown, at about 1/3 volume every time. Was fine last night, had them cranked for a long time, no issues (I assume cooler outside too) ** Was thinking of adding three 140mm fans to each side of the amplifier rack after I drill some ventilation holes along the sides. Soundstream Rubicon amps in amplifier rack 1.2500D - bottom 2.600 - middle 2.250 - top Speakers. CDT CL-62 (2 pair per side, front) CDT CL69X (rear) Fi BTL (Dual 2, loaded) Had the fronts in parallel from the 2.600 @ 2ohm load. Rears @ 4ohm load. Sub @ 1ohm load. Hooked everything up last night, no problems setting gains, front…

I want to make a box for my 03 yukon this is what I have H21"xL46"xD28" I want to chamber both 18's with a 3" port turned to 33hz is this right for my truck. I want to put the subs up with ports up is this right or should I go with subs up and ports back? Need help from the family. Thanks for all the advise.

Ok so...we all know that some vehicles are louder than others, some are more prone to flex so on and so forth. We all know that a 150 in one car can look and feel drastically different than a 150 in a different car. But what I want to know is... can there be more force behind a woofer's stroke which would in turn translate into moving more air and more flex BUT, it's not as loud on a meter? Let's take say...a pair 6x9. I can make the 6x9's play louder (to my ear anyway) than my pair of 12's but they move less air and hardly flex anything. It doesn't sound very "powerful," if you will. At the same time, my subs at a lot lower volume can move my mirror which the 6x9's can h…

does your wife or girlfriend really know the price you paid for your audio equipment ?

Well I ordered all my wiring last week when I ordered my amps and forgot to order the RCA's any one have any good recommendations of are they all pretty much the same

what is an all around better subwoofer an 18btl or 18 solox?

Sup SSA! Just wondering what other people had for systems or metered when they were 18. Vehichle, class/ organization competed in.. Any records, acomplishments,crazy things done or memories from systems or installs? Always interesting to hear of bassheads of my age/generation

Someone told me he doesnt trust setting the gain by a multimeter so he goes by um i believe the sub burning up then lowers it to a stable point Now that doesnt sound safe... how did you do it?

I have an F350 that has captains chairs with center consoles front and rear. The stock head unit is quit acceptable feature wise, and even the door speakers are not awful, the lower frequencies are quite lacking however. I thought a nice clean way to solve the lack of bass might be to put a JL Audio Stealthbox in the center console (preferably the rear one) I don't even know where I can get one (I'm in Kamloops BC Canada). Another option is a "custom made" box with another sub in the center console, or a "truck box" behind the seats ( ick :-/ ). Any opinions? Know how I can get the Stealthbox at a reasonably price? I do have a 10" Cadence Beast subwoofer here not in use. …

the following parts are what i have been looking at using in my system, does anyone have any thoughts (good or bad) on the choices here. I have a few amps lying around that all have pass through (eclipse, audiobahn, alpine) so one of them will be used in this configuration for the remaining speakers. 2 JL ZR800-CW 8" midbass driver to be built in a glass enclosure in my lower doors. 2 Hertz ML700 2.75" midranges to be glassed in my extreme upper door and angled at the drivers position. possibly 2 focal or hertz tweets, i have 2 alpine R tweets now that i think work very well so ill start with them and if they work well in this setup then great but if not ill swap to a…

21 total cubes 7 sealed 14 ported tuned to 45 hrtz sealed side will be built into my trunk. discuss.... ready go!

i just wanted to know what is the correct way of using oscilloscope to set amplifier gain. 1. Do you scope the amp with the speakers connected? or just hook up the scopemeter to the amp speaker terminal? 2. What test tone to use to set subwoofer amp, midrange amp and tweeter amp? Will 50hz and 1khz be sufficient? I do notice that if i set amp gain at 80hz and then play 50hz test tone, the amp output is clipped. So how low on test tone frequency shall i use for sub amp? 3. For music playback, is it better to use 0db test tone or -3db / -6 db for gain overlap? thanks

Guess what... This weekend, thanks to my hero...and lots of hard work and testing... Got on the meter, with a Street B box for my truck...

Can any one tell how to mount the three hole driver to the id mini horns thanks in advance.

I have done some searching and can't seem to find a post anywhere that addresses what people like to listen to during the setup of their front stage--not the subwoofer. What CD's or tracks do you guys prefer for setting up the angles of your front speakers and to generally test the imaging and staging of your setup?
