General Audio

Ok well here's the scenario: I am running a 15" BTL off of a JL Audio 250/1 (not the v2 one). On the amp along with the power light and protection mode light it has a light that is labeled "low Ohm" with the little ohm symbol. This amp's lowest rating is 1.5 ohm. My woofer is wired down to 1 ohm. But i figured it wasn't a big problem. OK so here's the problem - just now I noticed that on a certain note of a song (Lil Jon-Throw It Up) the light labeled low ohm blinks. Then i noticed sort of a popping sound coming from the box. So i went around to the back and popped the trunk. Then i could really hear the popping sound. I believe the sound it coming from the sub itself an…

my car lights flicker when running my sound system 15 if q 1500wrms with soundstream rubicon 2500 sub set up at 4 ohms = 800-900wrms for amp....the ground is secure and in a solid place metal to metal.. what else could be happeneing. my bass knob is turned only to middle when this happens meaning is probably hitting at 600-700 wrm.... i checked my car battery and its fully charged duralast gold wich is bigger then optima yellow top.. and i also have a kinetic 600 on back they the lights flicker when my subs hit high sounding bass. uuggh can only imagine whats going to happen when i connect the subs down to 1 ohm meaning 2500 watts rms when summer is over. What could b…

Alright my budget is around $800 and i was wanting to get Fi Subs. I really like the SSD's but i think that may be out of my budget. So i was wondering if the Fi.X's are any good? If not then i want to go with the SSD's And i was wondering what amp would be great at running these at 1ohm stable.

ok So ive been looking at build logs for awhile been on a member on ca for a while just never really posted anything. They'll make you wanna choke em some of the shyt they do. But i work at best buy and we get a pretty good discount on the speakers and stuff. So im trying 2 decide between a rf 1000bd thousand watts at 1ohm or an alpine mrp 1000 thousand watts at 2 ohms gonna get p3's or type Arghhs 12's. Just dont know much about either brand i've only owned kenwood excelon. Heard some rf stuff in my unkles tsx they where pretty loud, But i kno that the alpine subs atleast are over rated but the amps i hear get hot quick. Hopefully i dont get flamed for not having pics…

Spoke with Nick @ IA this morning. Customer service there never ceases to amaze. Anyway, got wind of some pro audio woofers coming. I can't say when, but I'm pretty stoked. Also a new Flatlyne coming. I'm glad they're branching out and expanding as a company. Congratulations IA! Now send me 2 of the new DR 12's, and 2 of the Pro Woofers. LOL

I met a guy at a competition a few days ago that had some sound deadening tape and I was wondering where i could get some. it wasn't like dynatape that's just the aluminum tape but it actually sound deadening properties. I figured it be nice for a few places in my durango where my sound deadener is too think. Any idea where I might be able to find a product like this? I did a google search and all the ones I have found appear to just be aluminum tape. Thanks guys!

I live this hobby----I enjoy it almost TOO much!

I hear about amp hours and cold cranking amps...and deep cycle... What numbers do you want higher and which numbers do you want lower?

So I am going to do an upgrade and was wanting some feedback on how it will do. The upgrade with consist of 2 ssa icons in a a 32hz box which I would like to have a 3.5cu ft after displacement of .16 x 2 from driver with a crescendo bc2000d and will run of 4awg power and ground til I have the money to get a spool of 2 or 0 ga wire. I'm a bit confused on the rms rating of the icons since they only show 1250rms but no info on peek, which I would like to know how far I could push them. Which way would or should I have to face the box so that more of the bass goes to the inside of the car and vibrate the seats to help massage my back after a 10 and a half hour day of work. Th…

Can someone explane what these charts mean? i don"t understand what these mean but the first cart being the highest at 50hz makes me think that i won't be able to hit lows well. i listen to slowed music 90% of the time i just want loud and low. i don"t really care about anything above 50hz or so. box is a 4th order 2 cubes sealed 6 ported tuned to 60hz 90sq in. of port. if i am right about not being able to hit low how can i change that? lower tuning, make chambers smaller? (8 cubes is the most space i have so can"t make chamber bigger without making other smaller)

I was looking around at mp3 players and trying to figure out what would sound better on my car stereo system. Came upon this new mp3 player called cowon j3 Koreon device just came out has eq and all other kind of stuff on it says its a SQ mp3 player also supports flac files. . One thing i found out flac files are the best sounding type files and ipods dont support them. Is this the real deal or can find something similar??? the price of it is cheaper then the ipod(Not that much).

I will be down in Dallas, Tx in a couple of weeks. Are there any shops some of you from the Dallas area would suggest? Looking at subs, amps, and speakers.

Simply, would cotton work at all in the same way as polyfill? I know one is meant for it and one is sure as hell not, but I have pounds of cotton and a wretched internet connection so roaming the internet isnt an option for the rest of the week. All I need is a yes or no, and a brief why. I was staring at a pile of cotton from dog-shredded pillows, and got to wondering.

If I do not care AT ALL what I do on the meter what would you thing is the lowest you can tune in a wall of 2 18' Nightshade V.2 18's? I LOVE the low lows and moving sheet metal/air. I also have about 20 cubes.... probably more if I push it but I dont want to if I dont have to... Thanks. LMK if I need to add more additional info...

So far I have: Hyundai Accent GT: gutted, stuffed with 65 cans of expanding foam, 14 gallons of bondo that need removed from the windows and redone by welding sheetmetal instead. 320lbs of 3/4"mdf for the false floor, ceiling, doors, roof, dashboard, and subwoofer chamber/wall. I had 5 1gallon buckets of Spectrum Firewall...sold 2, trying to sell the rest, and a 5 gallon bucket of Spectrum Sludge...trying to sell that too. 6 Optima Red tops...getting 2 more. An Audio Control 6Xs, getting a second one when i get the crossovers so I have 2 bandpassed signals and 1 HP, all at 24dB/oct, then using deck/sub amps to cross the subs. 2 Vifa XT25TG30 Ring Radiator Tweets, a KX200.…

I was rolling through an industrial area, an area right before i get to the center of the town i live in, and had my windows down with the volume pretty high. I was playing "Party and Bullshit" by Tech N9ne (good song) and as i was going through a light, there was a cop at a red light to the left. I muted the music instantly, but he followed me a little bit, eyed my sub in the back and then pulled me over. I knew i was screwed once i saw him. Still haven't got a court date in the mail. I would think I would have at least got a warning first, but nope. I don't blast with my windows down anymore though, it can be heard from way to far away. I don't know how much the fine i…

Hey guys, I was just wondering what the tuning frequency of a box really means. For instance, if my box is tuned to 35hz, will it simply not play any frequencies below that level, or will it sound like complete shit, or...? I just wasn't sure exactly what tuning frequency affected. I've read in a few places that higher tuning generally yields more spl, while lower is more geared towards sq. Why is that?

I was looking on the SSA store and was curious about the soundrive cables. They are on the pricey side, my question, are they worth it? Would the sound really improve as they lead you to believe? I've always run twisted pair, currently RF brand, never used coax before. From what I have read, if there isn't an existing noise issue, most any cable will do. Though, the only info I run across seems like it's all just speculation. I just moved my amps around and now my current rca cables are way too long.
