well ive had my sub since oct. and have been very happy with it untill recently it just seems like it was deff. louder a couple weeks ago. so i got the sub and pulled it out of my box to give it a once over beccause i dont have any meters of any kind. so i looked through the vents at the coil and it looked ok i guess was not all black. when you push on it, it make no scratching noise or any thing but seems alot looser than when new? and on the back of the magnet it has this (pit type things on it kinda looks like rust but its not brown its silver) stuff i got a pic but dont kow how to get it here its saved to my pictures can i get some help

OK, i have some bass'd up songs that I've been trying to burn to a dvd-r. i have a dvd/cd player in the truck. I put the dvdr in and choose my program. first time i did it as a data. Second time I put it in as burn an MP3 DVD. I dont burn very often. what am I missing?

I know not a lot of people carpet stuff anymore, I guess I'm stuck in the 80's lol. I've been trying to find brown carpet for the past couple months to no avail. I can find black and gray all day long. Have come across a couple pieces of tan. I suppose worst case I can get some tan and tone it with some tint, just would rather not if I can help it. Thought maybe you guys could point me in the right direction. Here is what I need (the lower half). Thanks!

I have seen a lot lately people posting threads asking about their woofers SQ and woofers SPL in different enclosures. Also, using the same to compare different woofers like, " I don't wanna loose any SQ and but I want a lot of SPL." I'll start with SQ, most "SQ" woofers you will see are less then 1000w and are optimized for sealed enclosures to aid with a flat response. When most people talk about woofers and their SQ, they just want it to not sound like shit, not a flat response. It's takes 10% or more Total Harmonic Distortion to hear it. Most people wouldn't even notice it at that level. So next time you say you want to say you want SQ from your woofer, please reconsi…

need a instruction manual for the above cd player,can anyone let me know if they have one.thanks

im about to do my very first system and i wanted to know if any one would even want to see it. all it is is a alpine type r 10 with a alpine mrp-m500 amp in a ported box. in the front is a kenwood HU and alpine sps-600 speakers. idk if thats a good build log but if anyone wants to see the build log let me know. im getting my amp in a few weeks so that is when i will be installing everything.

Well I was searching everywhere for an amp the would give me over 800x1 RMS for my HT woofer project. I really wanted an amp with a passive cooling solution, but the ones available with the kind of power I wanted were out of my budget. My solution is in the form of a Carver PM-900 amp. It is a live sound amp by design, but I hope to tweak it into a quiet HT amp for my passive sub. I went with Carver because the amp in my car that powers my components is a Carver made in '87 and it sounds very very nice. If something that old can work so well..... then you have a customer for life..... even though Carver is closing down Here are some pics...... Teh GiZuts. EWWW a fan!! …

I recently installed an inexpensive amp (Pyramid 4 channel 1600w) for the 4 mids and highs but now have a noise when ever I turn up the gains of this amp. I have a noise filter on the positive lead to the radio but still have this. Can this be from the cheap amp or the Iraggi alternator? It was not there before. Any ideas??? Thanks, JR

So I'm in the process of saving up cash for my new system. I'm almost 17 and working at mcdonalds bringing in about 150-200 a week. But anyways here we go, I only have room for 1 15 or 2 12's yes I considered taking out my backseats and making a 2 18" wall but that's a little drastic. Thought about going with a BTL 15 and putting it on a 3500 (either aq or sundown) But figured for a little more money I could get 2 12" BTLs and put them on 2 2k's (aq2200 or sundown2000) Both would be going in roughly 4 cubes @ 32 hz Is it worth the extra money for 2 12" btls? Only a little more cone area and 1000 more watts.

Just finished putting together my DIY home subwoofer. I used a Soundsplinter RL-p15 DVC2 and an Oaudio Bash 500 watt amp...... the box is 4.6 cf gross, 3.2 cf after port/bracing/speaker deductions. The box is made of 1.25" mdf and oak vaneered. The port is 2.25" x 16" and 43" long tuned at ~24hz. Mike at Soundsplinter and Todd at Oaudio are two of the greatest people and are willing to help in anyway possible. Also, I can't say enough good about their products!!! I tested the sub on Pearl Harbor and the Japanese attack scene almost brought down the walls..................

So I am going to do the big 3 on my 2001 Jetta. I am going to be using 4awg. When you guys upgrade the alt. to the battery positive is it a straight run, from alt. to battery? I dont know much about cars but my cousin said the the wire goes from the alt. to the starter than to the battery, is it like this with all cars?

Hey, i stay true to my name <<<. lol, but why does a sub seem louder with a window(s) down, than when they're up? I don't know if it is on a meter, or just to the ear, but shouldn't it be that if the waves are focused into a smaller space, it'd be louder? with a window down the air goes everywhere.. just don't understand. Also, if it really is louder on a meter to have windows down, then why do the true bassheads, modified vehicles spend thousands on concreting a vehicle and making sure every crevice is sealed, when i roll down a window and it's louder. Is it just the class they're in, and the rule is windows up? Or does it actually make it louder? Just kinda wo…

Im about to order new subs as we speak just waiting on a reply. Should i go with 2 of the ascendant audio havoc 12 inch subs or 2 of the 12 inch fi q series subs fully loaded? I know there both geared towards sq so any answer would be appreciated

i just picked up a 18'' fully loaded dual 2 ohm btl for my expedition and i was wondering what would be a good amp for daily driving? my budget falls between $300 and $450

Hello. I have two Sundown SA-12 d4 and a saz1500d v.3 and im having a little problem with what gauge wire i should be using. right now i would like to run it at 1ohm but im probably going with the 4ohm hook up. I still have my stock battery and alt and im not trying to run them down anytime soon. some people have also told me i can run them at 1ohm since i dont run my system all the time but im still a little sketchy saz1500dv.3- 1ohm =1500watt rms 4ohm=530watt rms

My alt arrived today and it's installed! Now I need to upgrade my wires, I am stuck on KnuKoncepts but am interested in Stingers 3/0. In the long run Stinger 3/0 is actually less than 3*1 of the KK for obvious reasons, and KK doesn't offer any 3/0. I hear that the Kolossus cable is almost 2/0. I plan to get 2 more 250 alts, so am thinking about the multiple run issue. I am now stuck on deciding if I want to go with Kolossus Flex or KLM. KLM is smaller, but it's a bit cheaper when purchasing the amp kit, and they don't offer any amp kits with Kolossus. What would everyone else do? Go for the Stinger 3/0, multiple runs of the Kolossus Flex, or multiple runs of th…

just as the title states, i've done some searching, and the most i got were 3 pictures on caraudio.com so i'm just trying to find anyone who has pics of the new toys for this year

Ok, within the next month or so I plan on getting a car stereo for my new car. I'm probably getting 4 alpine type component speakers, tweeters and cross overs with either a kenwood double din deck or a Power Acoustik touch screen deck to power the speakers. Now for the subs, right now Its between Fi and Dc, I'm leaning towards Fi but I'm just wondering what is the difference really between the Bl and the Dc?

Hey guy does anyone know how many cube you can get in an extended cab range 97. I'm thinking about buying one but don't know if I can get my 2 21 dp's in there.? Any advice would be great.

So I have a Poineer 3200bt, Pioneer TS-D1720C 6.75" speakers/tweets on a Pioneer GM-9500F amp, 12" RD Alpha V.2 powered by a Cadence ZRS-8 (1500rms). I have 1/0 gauge from my battery then it runs into a distributor with two 4 gauge leads coming out to the amps. 12 gauge from my 9500F to the speakers/tweets. I had the cadence amp and sub in my previous car ('98 accord coupe) and my lights would dim a little with the volume high. In my 2011 mazda 3 I sedan. I have my volume at 24 and the lights dim on every bass note, and I was on the freeway last night got my rpm's at 3k and at 26 my lights were still dimming. The bass on the HU is set to -4 and I can turn my speakers (wit…

I just got a Kicker s12l72. I was planning on getting the 40hm but I got the 2 brand new for a steal. But Now Im confused on what amp I should get. Will the Kicker 750.1 be fine. And should I wire it for 1 ohm or 4 ohms? Thanks

Does anyone have a dodge quadcab or have knowledge with the vehicle to tell me what i could fit behind the front seats. I don't have a problem lifting up the back seats because i don't plan on using it anyway. I wanna put 2 12's where the second row seating is typically. I know the second row seats lift up.

So I just filled my box with polyfill and I do all my connections. Then I connect the amp to the box, throw the fuse in, and jump in the car in anticipation of some wonderful sounds. To my disappointment, the music sounds exactly as it did prior to installing the subs. My first guess is that the amp isn't connected properly and is not powering up. Upon inspection the amp is turned on. It's a bit late and I'm too tired to start taking things apart. I'm pretty sure all the wiring is secure. I'm just hoping that the screws I used aren't the problem. I will feel like an idiot they are the problem. Instead of using a those fancy speaker terminals I used some bolts …
