General Audio

A year or two ago I had a box made by the local shop, I asked them to build it the specs of IA for the LI 15 but I'm doubtful they did so? The port looked and always seemed too small, it doesn't have any L shap as far as the port goes its just straight back and seems too slim...how would I measure the port to see the tuning and determine the total cubic feet? Also by first glance, does anyone think something is wrong here with the port....when I see most other builds by specs they all look a lot bigger...shady shops, only in it for the money smh.. I'll upload some more pictures tomorrow for a better look...

Well, my buddy gave me all his old stuff, but I feel kinda bad because he just had a kid and could use the money, so I'm gonna sell all of it and give him the money, BUT, I need some help with prices as research is leading to me to nothing, so What would you guys be willing to pay for this stuff. NO BS either. Rockford Power 501bd, and Power 451s. Both in immaculate condition. Come with a bridge to connect the two together.

My dad was looking to buy me a sound system for my birthday, i am looking around, he immideatily eliminated the idea of a subwoofer, so now i have a head unit and new speakers, and an amp (if necessary). I drive a 2004 jeep grand cherokee. I was going to buy with him today, Alpine CDA9886, 1 Alpine SPX-13 REF component set, 1 Alpine SPX-17 REF component set, and to power those speakers i was going to use a autotek SM4-800. I was wondering if this set up would be good, and if the amp would be adequate power for the speakers, i think it goes 100x4 @ 4 ohms.

I was looking for opinions on a how many batteries or Ah ( amp hours ) would people use to supply 20-30,000 watts? Fyi 2-300 amp mechman alts supplying the bank and 4-cresendo 5500 sub amps in use.

yeah well since bimmers alternators are expensive i decided to see if caps would do anything for me. Theyr gona be strapped to a JBL 1200.1 for a total of 2 farads. i didnt want to waste money on caps so i bought used ones that i got for 25 bucks shipped for non digital and 35 shipped for digital. I just came up with the rack idea when i was about to put em in, i grabeed a peice of leftover MDF wood from the box i made and put some leftover carpet on it and screwed it to the side of the trunk over my optima red top battery with a couple L brackets. Turned out pretty sick and im waiting on a D2 so i dont know yet if theyll do anything to help the dimming. either way i…

hi, I just got a Kenwood DVD player with monitor (KVT-819 DVD) and when i tested it, i do get the sound but the screen is not showing any video. It is still at the playback menu but i see no buttons to press to show the movie. anyone familiar with Kenwood DVD player? thanks.

Ok I just got my order of Knu 0/1 gauge wire in for my Power 1000 install. To make things easier I ordered 0/1 eyelets from Waytekwire.com. When I went to put the 1st eyelet on I could barley get it on the wire! I had seen this in the past with Knu 4 Gauge but this time I had to tap the lug onto the wire with a hammer (Not to crimp it but to get it on the wire it was so tight). I really don't think I will ever have a problem with my crimps seporating from not enough bite! Way to go Knu! If anyone is having second thoughts about ordering from them, order it, you can't go wrong! The wire is awesome!

Box for an 18" BL. 44.5" wide, 21.5" tall, and 20" deep. Port is 4.5" wide and 20" tall. Port length is 30" for about 30 hz tune and ~6.7ft^3 after displacements. I've never built a ported box and never had a sub that heavy. I've seen people do "window" bracing like I drew here...think this 2" wide bracing be adequate? The sub will fire up and port back in my Explorer (read that is a general rule to go by), but I can turn the box for rear firing the sub and firing the port up if that works better. Thanks for any thoughts!

i think i have seen people on the internet use power wire in place of speaker wire. is that possible or is that y they sell "speaker wire"

Quick Question What is considered Mid Bass? To be more precise, the frequency range. I hear this usually when people put 8"s on their doors (which I plan to do), but I would like to have clear what exact range is mid bass. Im guessing 100-200hz?

moderators making all these damn rules,20 posts outside the forsale section or else you cant list items,please i have 34 according to this board,pry 30 of them came from the classified section.but truth be known i was around from the very begining when mark first thought up this damn place.i can tell you why i dont post much here,its because of half of you dildos who think you run this place,well without me and a handfull of others who originally contributed to this more as a local board,you peckerheads wouldn't have a place to be keyboard commandos and act like your chit doesn't stink.theres other stuff that bothers me too,but i really don't feel like posting more since…

I have an amp and a pair of speakers and im not sure if they are good or not. What would you guys rate them from 1/10, i got them both for free so im not to concerned if they are good or not.

I searched a couple of weeks back for a converter that would allow me to put 6.5 inch midbass drivers in the doors of a tahoe and was able to find it. Now I am ready to purchase them, and I can't find them anywhere. I found them on ebay, but after hours of searching I can not find it. The speakers in the door are built into a plastic type converter so they can fit into the hole. I just need aftermarket ones so that I can install a standard 6.5 inch speaker into the door without any modification to the door itself. Thank you.

I will be soon upgrading some components in my system. I have a new SAZ-1500d v.2 that will be paired up with an Xcon 12. I will also be getting a DC Power 180 amp alternator and will do the Big 3 also. I just have some questions. I haven't ever worked on a system dealing with this much power, and just want to make sure I have everything that I need. First, my current setup is a dual amp setup using Rockford 1000-1bd amp and alpine pdx-4.100. I used a 1 Farad capacitor (Ya, I know ) basically as a distrubution block for those amps. Electrical is stock. The capacitor will go away when I upgrade, so I have been looking at distribution blocks. I know I will need a…

I posted some pics there a month or so ago and don't seem to be able to do it again....is this section down or is it my browser or something else I'm doing wrong?

Well guys im on a super tight budget for my next build so im looking for someone in the Charlotte/Mooresville, NC area that will allow me to use there tools to cut the wood for my next box. Im in an apartment complex and i have no means of getting it done and pretty much all local shops want from 500-1000 to build an 9 cube box and to me that's ridicules. My last box cost me 35 for the sheet of wood and my time to build. If anyone out there wood be willing to let me use there stuff or cut the wood for me for a small fee id much appreciate it. Thanks, Alan

is having a wall in the back of your vehicle illegal since u cant see out of your rear view mirror? thinking about doing a wall in my daily driver but not sure if im gonna b getting in trouble for it or not...any input would b great. thanx.

Its been a hot minute since I've been back around the SSA Forums. So what I have to share is our new M3 lvl 6 15. http://youtu.be/LgINN67wNHs?list=UUCyrPB8lLWhPP-oWTfTP7hQ New proprietary 15in basket uses a newly tooled 10in spider. It can accomodate a full 4in peak to peak and comes in with a 28hz fs. Just what the low low tuned daily groundpounders need! In the video sub was on a 10k in a box built for 2 lol.

so much for my eclipse ti's.. any chance ill get a fair reimbursment?

I have a Chevy extended cab full size I want to compete with again, I don’t want a wall or blowthru should I do 4 12” or couple 15” or 18”? one big sub or multiple subs? i will be changing out my alt and adding batteries as needed i use to have 3 JL 12W7 I’m a slot port box with one 1000 slash amp per sub in an s10 extended cab hitting 153.4

This may sound kinda newbish but I was wondering if anyone could tell me the formula for getting the true surface area of a sub.

my friend bought this sub that he is putting in his car when he gets one but he said i can have it til he gets his car its a interfire, i have never heard of them before. im pretty sure its a interfire IFB-15D. i wired it up and listened to it free air and it was real quite and didnt move much. would a box make it alot louder? also i need a box design if anyone wants to draw me up one it next to alpine type r 10

where can i get my wood cut, i dont have the equipment to do it, only a jigsaw, but suck at it

well i had ordered some items from someone over at CA.com Friday 9th. I received the image dynamic speakers thursday I believe without the sub. I couldn't imagine why I didn't get both of them but I just shrugged it off. Well.....I just got back from a trip and I told my parents about it and they said "Yeah, we have something to tell you." My dad hands me an envolpe that has nothing but a label and an aplogoy note from the postal service. Basically someone either A) stole my sub or B. lost the package which I have no idea how you lose something this big. so we are going to go talk to the people about this monday. I'm really bummed about it

I have a custom 2013 Q motor with a 6 spoke 18" basket and spl audio recone. I had it in 6 cubes tuned at 32 and it sounded great but i have to make space for my daughter. I was wonderingb could i put it in a box thats 22"x22"x22" with the sub inverted? Tuned to like 40hz? External ports
