General Audio

Just saw this, worth a look:

Hi all- I have been battling with alternator whine for a majority of my car audio hobby. I have tried countless things. I had just made an LC filter to filter out noise in the power line of my radio thinking it was finally it, but unfortuately it remained. Then it dawned on me, I have 2 amps for speakers in my car now and I tried disconnecting the one I've had for years. The noise went away, which is great to finally know what is causing it. The problem is I don't have the cash to buy a new amp for my midbass. Does anyone have any idea where to start troubleshooting inside the amp for something like this? I'm a fourth year electrical engineering student, so I'm quite …

Hi all, longtime lurker, first time poster. I'm not new to car audio, but I am new to this forum. I have an issue with my system setup, basically that there isn't much bass over the factory premium audio system. It's a long post so bear with me. I am trying to get a similar output to the systems I've had in the past but am coming up short. My previous system was in a 2007 Grand Prix. It had a Kenwood Excelon headunit with sub out, two PPI Art series amps (an A300 running the highs @ 2ohms and an A600 bridged to 4ohms to run the subs), the highs were a pair of 6 3/4"s in the front doors and a pair of 6x9s in the rear deck- all the high speakers were Kenwoods, and a pair …

i actualy live 30 mins west of Toronto in Milton, and i was wondering if anyone near here has an SPL meeter...i wanna see were i stand before the comp on may 11...ive never been meetered before. thanks guys

I installed my big 3 about 2 months ago, and I was in a hurry to get it done. I want to help shield the wires from the heat and possibly change my battery terminal to a ring-style terminal. Will Techflex be enough? Or should I put on some wire loom as well? I'd like to be able to just put on some color matching techflex to my power, ground, and amp cables, but if the AZ heat is going to beat down on those wires this summer, I'll wrap some wire loom around them if need be. What do you guys think? EDIT: KnuKonceptz 0g wiring. According to their website, with the insulation, it's 16mm thick, just over half an inch. Should I go for the 1/2 techflex or the 3/4? Same questi…

I have a 1.3 ft^3 vented box tuned to 33 hz and an Audioque 1200w amp. I placed an order for a GCON-10d2 so I can have plenty of head room and keep the gain down on the amp. My goal is "SQL", not looking to flex all my body panels. I chose this particular size box and sub so I can keep most of my trunk space available. I keep thinking I should have chosen a more powerful subwoofer that can handle ~1000w RMS (ie. FI SSD or AQ HDC3, etc) I'd hate to order a new sub just to wait even longer for the build time. I listen to rap, R&B, techno, dance, dubstep... All advise and recommendations is much appreciated. Thanks!!

Is there anyplace perhaps an Instagram page that has funny car audio pics? making fun of certain subs or Idk anything funny? That would be greaattt......(office space refference)

OK so as you guys know im overseas in germany right now. i went to a local car shop today and asked how much it would cost to build me a box for my Massive Audio DMX stg2 subwoofer and he quoted me 150-200 euros which is about $200-$300 for this build. the box would be made of MDF and will be carpeted. i asked about bracing and if he could build it in birch instead he didnt know what that was. the language barrier owns me and this guy. I asked him if i got the materials if he could build the sub and he said yes. so theres an option. I hear Birch is stronger and lighter, but harder to cut and you have to prep and sand the area, blah blah. anyway is this a good deal? I was …

Hey guys, just recently bought a 2 channel and am now wiring or trying to wire it. i have come to the point of putting the speaker wire to the speakers. but i have come across a little issue. you see all the previous wiring is connected to the driver and passenger door by a single clip. there is no other opening in the door. and theres no room to slide my speaker wire in there. so how do i get the new wire into the door? the only way i see is to drill a couple holes. what do u guys usualy do?

My alt charges at 14.4 Have a batt bank, and stays above 13v whith hard bass hits. After a while my subs loose "thump" I still have some bass I'll turn the volume down and it comes right back. I have my gain set to 7 at 28 volts well below max output. Brand new T1000-4ad running two P3's.

For fun: If you had to pick one brand for amp, sub, speakers who would you pick and why ? Let's say $5000 budget on one and one dream no budget build. omit head unit so more brands to pick from. SQ build and/or SPL your pick. Just for fun, curious to everyone's picks.

what would it take to have surround sound in a vehicle and about how much will it cost to do so

It was a nice day, and the shop is closed on sunday so I decided to break out the old TL and do some testing. At the moment, the ports I am using are for testing purposes, just form tube, no fibreglass enforcement or even flares for that matter, so I know there is still more I can squeeze out of this. All testing was done with Two 15" Icons on a Crescendo 3500d (At 2 ohms keep in mind). Pretty basic electrical with only a single kinetik 1400 as a second battery. First Test : 6.cuft / 8" formtube tuned to ~27hz 30hz - 137.94db 35hz - 139.19db 40hz - 141.53db 44hz - 143.20db 46hz - 143.52db Second Test : 6cuft / 8" formtube tuned to ~ 33hz 30hz - 138.23db 35hz - 14…

Me and my buds are doing an aftermarket deck install on a 91 Pontiac Firefly and need to know wire color info to hardwire it to the cars connector. We’ve looked all over the web and can’t find a thing! Called car audio shops and they all want money. Here are the colors to the wires; hopefully someone can help us out: A: Solid Red B: Solid Orange C: White w/ Black Stripe D: Red w/ Black Stripe E: Orange w/ Black Stripe F: Solid White G: Red w/ Yellow Stripe H: Solid Black #1 I: Grey w/ White Stripe J: Green w/ White Stripe K: Solid Black #2 L: Grey w/ Black Stripe M: Green w/Black Stripe This is our decks wire color info: P o w e r: Memory (+12v Constant) - Yellow Ig…

I'm going to be putting a marine speaker under the hood of my car behind the grille I want to run a kill switch into the cabin so I can only turn it on when needed I'm looking for something that will not cause me any resistance or quality loss problems I'm not real sure how to wire something like this until I see the switch but I'm guessing you only run the (+) to the switch and leave the (-) one whole wire and no i am not turning my car into an icecream truck........ its for the drive in movies Thanks and have an awesome day

I'm going to be selling my rockford t1 15 but I'm going to build a new box for it. My current one is tuned to 38hz which is probably why my lows aren't to good. I want to try tuning it to 32hz unless someone has a better recommendation. This is the box I have right now - http://imageshack.us/a/img828/4849/imagesyn.jpg I want to keep the height the same, but knock the depth about 2-3inchs if possible, and my width can be bigger. I'm not very understanding of port size and how to get that tuning/and get the cubes it needs with the different size port.

I need a box design for under the rear seat of my truck but the thing is I don't know if I want to go with four ported 8's with about 600 watts a piece or two 10's ported with about 1000 watts a piece...which setup will be louder? And who is a good enclosure designer?

Just bought another truck to mess around with and looking into doing a blowthrough. I figured if I'm doing a blowthrough I wanted to do 4 15s. I'm gonna purchase a h/o alt of course. My first option is 4 sundown sa 15s running off of a crescendo bc3500d or a sundown saz 2500d. Looking to only spend about $800 on the amp. Would the crescendo out do the saz for the same dollar pretty much? 2nd option was to get a lil louder. 4 sundown zv4 15s running off of 2 crescendo bc3500d or 2 saz 2500d. Or would that not be enough power to call it good? Would the much higher power subs My question is with the power I'm thinking of giving the 2 options what would be more ideal. I wa…

Today will be my first competition. Its only local but it still is exciting for me. Im mostly excited to see what numbers Im putting up as Im running my system and to see how things are operated as ive never even attended a show before. Wish me luck! Goin to rep some SSA and convert some of these main stream nut huggers

Putting out some feelers for shops in West Texas that do honest, quality work. Specifically, rear seat entertainment. Primarily in Lubbock, but Amarillo would work too. Failing that, Abilene? DFW? Austin? San Antonio?

So I reciently purchased a sundown SAZ-2500d v.2 form SSA and am a little stumped on wiring. I will be running a RE Audio xxx 15'' dual 2 ohm at 1 ohm. The amp has two positive and two nagative inputs, can I use both? Want to get the best power out of this as possable.

I saw this video from D'Amore and was wondering what everyone thought about it?

Hi guys The last forum I was a member on misguided me terribly Please help me with some questions I have thanks! 1. can i use 2 ground wires for lower resistance? 2. are 5/7 eq band head units pointless for a bass head since the eq should be at 0 anyways? 3. why is a 4v headunit better than 2v? 4. do you guys with multiple alternators have custom belts made? 5. what specifically is in an expensive amp that a cheaper brand does not have? 6. how can these guys patent a basket design? is it their reward for finding the most effecient design first? 7. why don't people use the 21" incriminator death penalty more often in builds? 8. what is the difference betwee…

In my searches for raw drivers I came across Renaudio. Everything looks good on paper so I was considering looking into giving them a try. Has anyone ever used their drivers before? Any thoughts or opinions on their quality, sound, or customer service?

Kinda in a dellema ATM. So my 2 front speakers blew the other day (jbl got 628's 2-ways) so I put the factory ones back in until I figure out what to do. Thing is I got em from best buy and they no longer carry any car audio (in Canada anyways) so they sent me to future shop for a replacement (I bought a warranty so I get a free swap). Annddd future shop doesn't carry those speakers butt they can swap them for something else. So I'm not really sure what to do. Im kinda on the fence on switching to components (leaning more to the I don't wanna side) and am going to buy a 4 channel amp soon. If I was to swap them: http://m.futureshop.ca/defaultpage.aspx?lang=en#/catalog/pro…
