Well i just put 100 dollars in the bank and was bout to send the money to crescendo to get their new mp6 pa mids, come to find out they ran out of stock 2 days ago!!! they said they still have some 8 ohm versions left for sale. i was gonna run 4 on a mb quart onx 4.125. well i planned on using the front channels for the mids and the rear for my tweets. well i cant buy the 4 ohm versions so would it be better to get the 8 ohm and run them 2 on left front channel and 2 on the right front channel for half the power i would have been getting, or wait 43 days til the 4 ohms get back in stock?

need some help on some 6x9's. i have alpine sps-600 in the front doors so i was going to match them with the alpine sps-609 but then i saw the spr-69c is not much more money. should i get sps-609 or the spr-69c with no amp?

Window all the way down with hair blowing out of it, or window cracked with hair blowing out of it?(Just curious)

I have the 2200 A.Q. amp. The grounded wire got hot enough to melt, so when being replaced the power wire was still connected. When connecting the ground back to the amp it caused a popping sound and white smoke to come from the amp. Is it ok to try and reconnect it still or would it have caused damage to the amp.

So today i went to replace my girlfriends hifonics bxi 610 with my old rd 1000.1 v1 amp. Before i made the swap she said sub was playing. After i swap the amps i go to tune the amp by ear and absolulately zero output from the sub. So i grab my dmm and turn it to the ohms setting, with the car off it reads .9-1.1 but when i turn the car on it goes to -23-25. first i think maybe the sub has a bad lead or something so i go grab another perfectly working sub and get the same results. Then i was thinking its gotta be the amp then so i switch them back, same results on both subs and both amps. So now shes without beats and its all my fault of course so i wont hear the end of it…

Hey everyone, me and a few others on Ecoustics are getting a little get together worked out right now. We have a place in York PA (eastern PA right above the MD/PA border) that we can do it at right now. But we might change the location to a place like Wilmington DE. The date we should be having it will be March 15th. Nothing is official to say just yet but we should have everything locked in place hopefully by mid to late this week. We have a guy coming out who is bringing his AC mic although he said something about bringing a TL but I'm not sure if he has one or not. He said he is going to charge a little fee to get metered. We aren't looking to have this thing be a com…

i went to MetroPlex Battery inc. in Dallas Tx today after work to pickup the only Speedcap i could find in North Tx, for my US 8v gc battery- for free.... he had an extra... ( good Karma ) and i was discussing how audio shops put our nuts in a vise and jack up ( tripple ) the price of any battery that will put out power.... so he was showing me all the different batterys he had for fork lifts / sky lifts etc and i mentioned i had a chance to get an NSB 90 and missed out cuss i dident get paied in time... he said he had 2 reconditioned Nsb batterys 1 was a NSB 90 the other was an NSB 110 ---- he sold it to me for 35.oo + tax i now have over 4000amps @ 12.85v for my S…

Alright i got 2 dvc 2 ohm subs i wired them just like option 2 on this graph so i can get a 2ohm load http://www.rockfordfosgate.com/rftech/woof...mp;woofer_imp=3 and my DMM is reading 1ohm did i do something wrong? NEW PICS! for everyone to double check! the ohm reading changes from 1.7 - 2.0 though just keeps changing

I'm having a problem getting a straigh answer on whether or not i can install my two 12" kove subs into my 96 aurora. The problem is I have a factory bosse system with the factory cd changer. According to a few places I've called my subs cannot be added without a new cd player or getting rid of the speakers in the back. I think some of the places are just trying to make me buy a new cd player. I also don't see why I would have to get rid of the back two speakers to add two subs. Any suggestions would be greatly appreciated.

I decide to make a couple vids of hairtricks. My last box was much easier to do hair tricks because it was tuned at 25Hz. This box is tuned at 38Hz and is much harder. But its all for fun so enjoy... p.s. My mom is a teacher and we did this video for her students. This is the better vid.

hmmmm...... where to start.....i know i have done this before but i havent really did it the right way, and in a manner that could be taken seriously. i am planning an overhaul of my beetle i will be recieving in just under a year. (dont ask about the Contour, long story about that) i want firstly, to get a good system in it right off the bat. following that, i want to get a black paintjob, tints, and some spinners (total joke on that last one, for christ's sake itsa beetle!) you guys all know me well, i like it loud and cheap. but those dont always (rarely ever in fact) go together. i want to know if i could go to far as to three 12's across the backseat. i dont really w…

Hey guys im hosting a car audio competition in my hometown, just wondering what tips should i take while planning it?

Hey guys to give a little info on my set up so far, I'm sort of on a budget but in need of bass who isnt right? Well i bought 2 2010 kicker cvr 12"s for $100 for the pair going to have them on a crunch pzi. 1500 i know p.o.s amp but its what i got for now the box specs. are: 30 inch wide X 14 height X 29 deep. Port is going to be 4 inches wide X 12.5 inch tall X 18.5 inches depth tuned to 32 hz with 45* in the corners each sub is getting 2.486635 cubic feet each would this box sound good or what should i add or take off. Any info or input would be greatly appreciated

So I will be pairing the 4 ohm Crescendo STS-1 Silk dome tweeters with 4ohm Crescendo PWX 6.5's . The tweeters came with crossovers just for the tweeters. Amp is a nvx jad800.4 which does 125 x 4 @ 4 ohms. if I have the pwx's hooked up to channels 1 & 2, can I connect the tweeters on channel 3 & 4 and essentially barely increase the input sensitivity on those channels? Doesn't seem accurate whatsoever to me and I am thinking I could seriously fry my tweeters from the get go. Would that still be considered going passive with tweeter crossovers or am I diving into active territory? Am I better off getting a different passive crossover that I can connect both pwx &a…

Well, I usually stay away from all the local shops, there about 5. But I was bored so I went around yesterday to see whats new. Theres one shop thats actually pretty knowledgeable/cool. A old guy at Autosoundaddiction(VERN) We were sitting around talking, this kid comes in with a 15" Team RF fosgate(sweet SPL 4hp sub) the dustcap was loose, but he was sure it needed to be sent to the factory for "repairs" Tested the coils, their fine. Vern says " I have some CA glue in the back I'll just glue the dustcap back down and you'll be good, save you a couple hundred" The kids like no"I don't want it half assed, it needs all new parts." WOW I tried to tell him, that its jus…

I Just put the pio 880 in my 98 expe, and that deck is awesome. I am in love. It even makes the factory set up tolerable.... almost. Well I know what I need to do next and thats basic electrical and deadening, while I wait to see if I want to do an alarm etc. I'm going to go active in the front and am still undecided about placement of speakers and then in turn about what size drivers..and how I want to go about it, so I'm going to switch gears and work on the bass and deadening and electrical for a while. I am completely lost on the big 3 and it will take me a long time to figure those out I think. I have read it's practical to just double up with the factory instead…

can any one help and give me the equations to calculate the box airspace and tuning on the box ... bcause i want to learn a very accurate way to design boxes like calculating them by pen and paper without using a software. PLEASE HELP

Im going to build a system for my bike and i dont know what box dimensions i need i will be using 2 8's and 2 6x9's and a small 400 rms amp the box i was thinking of was with the 2 8's each one on each side and the 6x9's on top of the box ... something like this but with 6x9's

I'm hoping someone can point me in the right direction. Forgive me...I'm not very knowledgeable about this stuff. I have a 2001 Chevy S10 ZR2 (4X4) I ordered off Crutchfield and they sent me my new Sony Digital Media player and a wire adapter kit. The problem is it appears to be the wrong adapter. Crutchfield only has one option for my year and make and it's that one http://www.crutchfie...ss.html?tp=2977 My GM factory plug looks like this... Next part. I start to drive off without the original factory stereo plugged in and got about a mile down the road before it started dieing on me. I deduced that this truck must have some kind of security protection (I have no clue)…

Just got this email from the police officer handling my case and lives next door:

I'm in the market for a new vehicle; and, I'm going to upgrade it. I have questions about today's vehicles: 1. I'm looking at a model that has push button start and factory remote start; what challanges are there when adding a partial or full alarm on it? 2. This model has the full sat radio/navigation/premium head unit and I wanna at least add better bass; what challanges are there in integrating to this head unit?

I have a question about the power wiring of my amps. Hopefully this nice diagram will let everyone understand. Thanks, Ben

Basically, I'm trying to think of the most cost-effective way to build a shelf that's rock-solid steady for my turntable. I've been floating a lot of ideas around in my head, from "floating" a piece of MDF in a little sandbox-type thing, to several layers of MDF on soft rubber pads, to wacky ones like a suspended magnetic table (most likely not even possible). So...I'm trying to brainstorm, need ideas for a table that's immune to vibration and help to deaden the internal vibration from the unit itself.

Lotsa stuff i got recently, an Eclipse 8053. The marantz SR8400 going to my HT system. It wouldn't fit my old rack so i had to put it on my TV stand. RE XXX 6.5 and they accidentally shipped me a re 6.5 so i took pix for comparison. Lastly, a Concept 1200D i got real cheap.
