Hey. Its me again, I FINALLY bought the 2 12" JL W3v1 Model Subs! There 300wrms Apiece and I have a 2004 Chevy Aveo Sedan Like This... http://files.conceptcarz.com/img/Chevrolet/2004-chevy_Aveo_manu-034-1280.jpg And Im thinking about having my friends friend build me a Inverted Wedge Box. What would be louder in that car with those subs? A Inverted Wedge Box?? Or A Ported Box?? Heres info on the Inverted Wedge INVERTED WEDGE DESIGN

Being a dealer for DD and working close with them i decided i should post this thread. Lets keep it intellectual of course but i want you feedback on over all DD products and everything. This information will be passed directly to them in an attempt to better their perception and reputation ( not that its bad of course ). Let me know what you guys think. Good and bad, give me good well written posts with positives and negatives about their products. I look forward to hopefully using your opinions/statements to help make DD a better company. I am trying to get someone from DD to come onto the forums themselves, so im also trying to show them there would be benefit in it.

Well I had my first spl reading ever and was fairly happy. My system consists of 4 RE8's in a sealed enclosure that is way to small approximately 1.9 cubic ft total with an OLD RF 800.2. This set up is in my 95 impala ss. Well for my first system I was happy with my 131.8. I have a pic but I am a retard when it comes to posting pics. I was kind of wondering if I was pretty much on par for this setup or am I off a little.

OK, Well I have tried a few things and nothing worked. But first I will tell you my situation. I have a 92 Ford Ranger xlt and a FI BL 15 in THIS Box with a Pyle Audio 2200 amp. My problem is that When the box and sub are in the cab of my truck and the head unit is off or on it doesn't matter. I receive a very loud buzzing sound when I turn the key on. Here is a video below to explain what happened. http://www.youtube.com/watch?v=4JuZPgoYyYk Please help me as much as you guys can.

i have a 2005 honda civic i need a bigger alternator im looking for a 150 amp or more anyone no were i can get one

hey guys. i'm fixing to fiberglass over my back speaker adapters in my eclipse.whats the best/cheapest material to use for fiberglassing.its gonna have a 3/4"template holding the 6-1/2" in place just need to fiberglass over it to cover up the unused space. i was just gonna get some fiberglass resin from autozone and some material from wal-mart. any tips on it would be appreciated. charles

No more rumors

on my way home last night i noticed that 1 of my 4 sets of comps wasn't working. so i was getting no volume out of the tweeter or the mid bass. I quickly realized it was channel 3 (front right). here is what i did: First I checked the resistance of the speakers and i got an ohm reading of 4ohm each speaker (mid/high) • so this tells me that the speakers are fine Second I check the output of the amp by putting my dmm in voltages A/C • I then compared the output of the channel 3 with the other channels and i got the same amount of output on all channels • so this ruled out my amp as an issue Next i put the dmm in ohm, and check the wires going into the amp leading to th…

Instead of cutting a hole for a terminal cup I plan on running a 1/4 inch or so bolt through the side of my sub box. My question is, what type of bolt would be best for power/signal transfer? -Standard Steel -Stainless Steel -Brass -Aluminum -Chrome -Grade 8 Steel -Copper (not sure I can find it) There is just so many options and I don't know what to choose. Thanks All

So i went to a local car audio shop probably less than a mile from my house and i finally got to hear a loud car. The guy that owns the shops name is Michael Jones. He also holds a bunch of worlds SPL records and titles. His stats Idk, i thought it was pretty cool that he lives right here in my town (around 100,000 people or less) He also says he has a B&K sound and vibrations sound level meter. Supposedly one of the best ones out there and he said hes 1 of 3 people in united states that has one. Also has a termlab so i will be metering my truck soon =) Edit: Oh yeah the loud car i heard was a nissan pathfinder with 3 15" DD 3500s i believe with 2 strapped DD m1's. I…

Yes!!!! They have super tweeters coming soon as well. http://www.rockfordfosgate.com/products/product_details.asp?item_id=223198&locale=en_US&p_status=

As the topic states, I need to get my hands on some parts to start building up my pile of motors that I have sitting arround. these things are just going to go to waste otherwise.. all have 3" coils--all from big name woofers so If someone can point me in the right direction it would be greatly appreciated. What I need: Baskets, Surrounds, Cones, Coils, Spiders, dustcaps, tensil leads ect... I've got a bunch of identical motors to build and some odd ball's that use the same coil (but have a different motor design) thanks in advance

Just for example...I want to run 4 subs off a monoblock amp with 2 channels of amplification. If I run 2 subs wired in series to get my desired ohm load. Say I'm putting out 500 watts to one channel of power, do both subs see 500 watts? or is it changed a little?

actual technical question follows ---> Basically as the title says...I've decided on an 5.25" or 6.5" MTM design that works for my app, but I've got a choice of ribbon or regular tweets. The ribbon kit is double the price of the normal one at $550...I've never owned a speaker using ribbon tweets, so I don't know if they'd be worth the price increase. FYI, the speakers I'm looking at can be found at http://www.parkeraudio.net. 95dB/W or 98dB/W at a stable 2 ohm load. Thanks. :musik05:

ok, i got a hatchback and about 8-9 cubes to put it in. 2 RE 12' HC's and am gonna build a big enclosure. what do u recommend for the box size, and wat it should be tuned to. i listen to lots of rap and occasionally rock. ty in advance. Sorry im still a newb lol.

I may be buying Tirefryr's JBL BPX2200.1 if he still has it which i believe he does the last time i talked to him. Anyways what do you guys suggest i should do to my electrical system right now to handle it. Only gonna run it on one BL with the gain turned way down. So im thinking 2 runs on 0 from the front back and the red top i have in the back right now will handle it or am i sorely mistaken? I figure i could sell the 1200d to pay for the HO alternator but what do you guys suggest?

Alright well iv decided to get a 15"ssd with a soundstream rub1600. I need power wire... and should i get a capacitor?... i have all stock electrical. But i ordered a volt meter to watch and make sure my voltage dosnt go to low... but i am thinking a 5 cuft box with pvc ports... tuned to like 35hz... or lower... not sure yet. Possibly square interchangable ports.. its going in a tundra access cab.. any ideas? I have a sheet of like 3/8" plastic for a window in the box. Possible leds in the box... not sure yet but def a window. So any crazy ideas to make this build original? Im 18 but pretty skilled with a saw and router.. let me know.

Are there any sub box design programs that work for macs?

So I have been doing the car stereo thing for about 6 years, even having won several competitions but have never even considered impedance rise when building cabinets and I just wanted to get some info on this phenomena. I understand that it boils down to the size/shape/style of the box and any obstructions such as wires, braces, etc. 1. how can I test my setup to find my impedance rise? 2. can impedance rise be combated by wiring below rated amplifier impedance? 3. are there any build orientations that are more resistant to this? (sub/port firing back; sub firing up/port back; etc.) I am installing in a 2004 pontiac grand prix and a 2008 ford escape, any info will be gre…

Here is the little back story.. I bought my car off my dad, who previously installed some aftermarket audio system. I decided i wanted to upgrade the components and he said that he has Infinity Reference 5.25" components in there already so I decided to go with the Bravox CS50k (5.25") component set for ease of install. Today, I go to install the Bravox's and notice that the Infinity's are indeed 6.5". So now iv payed $150 dollars for a downgrade in size.. Great.

Hey fellas, not sure where to post this so here it is. I have a bus we drive for church on Wednesday's and we got a bunch of rowdy kids(saginaw area) so i installed a radio on the bus and we have a CB style mic but its not powered so as you all know the signal it sends isnt strong enough to amplify to make it audible. So my question is do any of you guys know an easy fix for this? Like a mic that is self powered or what not? Any help or direction would be great. 35 rowdy kids imma end up with no voice.

Love the look of the boxes how to I go about ordering one ?

Alright I think im done with loud bass.... I found a 15" MK2 Brahma for a good price and im gonna get it. What would be good to run that sub on for a SQ setup? Also how can i bring the quality of the sound in my blazer up?

so i just installed my new sundown 100.4 amp and i have a terrible distortion problem even at a barely audible level. ive double checked all the wiring for proper polarity and checked that i have a good ground connection too. ive also tried speakers which i know are good as well as inputs that i know are good. the only inconsistency ive found is the the remote from my deck puts out 11.3v and the book that came with my amp is asking for 13.8v would this cause the distortion or is there something wrong with the amplifier. thanks for the input

I have an MB quart 4.80 running 6.5" 3 way infinity kappas in the front and infinity kappas 3 way 6x9s in the rear. Each has a 2 ohm nominal on each channel of the amp. If I bought some crescendo super tweets would I be able to wire them and still make a difference to my front stage? I am planning on upgrading my 4 channel in the future to a Hertz or quality 4 channel after I get my alternator this winter. Should I just wait until I upgrade my 4 channel and just buy a component set?
