Anyone know of a good site with the crossover math? -or- Design software? Though I'd prefer the calc's -Nick

I was wondering if anyone here has an Expedition or any other vehicle (other than a tahoe) and has put a D3100 under the hood. I think I saw a picture a while back of someone with a Ranger or F-150 with one under the hood but they mounted it sideways. If someone can offer some advice on something I could do to make it fit I'd gladly take it. I'm gonna get it under there one way or the other!! Thanks.

There is a bunch on eBay for under $10. They seem very cheap looking and I am not sure where I would go about mounting them. What meters are recommended for update speed, accuracy and still maintain a sleek appearance?

hi, i currently have a 200 amp alternator ( excessive amperage) but i have had a problem. it came with a 2" overdrive pulley and i need a shorter Serpretain belt for it and they don't make one short enough. so i have to go with a 160 Amp alternator because of the Serpretain belt problem. the amps i have/ going to be using are: Us amps md1d @1 ohm (1200 underrated watts) and Jl Audio 450/4 because of the RIP Power supply. Would a 160 Amp alternator be big enough for roughly around 1650 rms watts? and i am going to get a Yellow top Battery under the hood.

Im in need of a website for my company. I Dont have any spare cash at the moment, b/c I am out so much for startup cost, but have spoken with Scott Atwell of Fi Car Audio, and he is willing to help me. I would like to trade Fi product for a nice webiste. If any of you guys know anyone that might be able to help let me know.

When i want to show off my stuff im always afraid of blowing my subs. I was wondering if there is a formula or something that you guys use to make sure you know where the subs limit is? If i dial in my gains to where the amp is not sending clipped signals when the head unit is all the way up, does this mean that i can turn the head unit up as much as i want and not have to worry? I have an Audioque HDC312 "1000 RMS" sub Audioque AQ1200D all wired at 1 ohm

I've got a competition tomorrow and had my batteries just arrive this evening. Setup is two hc2400 and two hc600.the question I'm posing is only one run of 0 ga. Enough for just this one time event or just forget about it and spend the day making a second run. I'm powering a sundown 2500. What's your thoughts? It will have the second run done I'm just not sure if only one run will hurt the batteries.

Alright, so I'm trying to plan out my car system and ive ordered my subs/amps. The subs are 1x 18" FI BTL and 2x 12" FI BTL's. I have a 4 door dodge stratus and I was planning on removing the back seats where I would put the 18" in a 7'-8' cu ported box. The two 12"s would go in the trunk area in a single ported box (can do two seperate boxes if that would be better). The trunk/cab would be connected due to the removal of the back seat. My question is, would this be a very stupid thing to do? Im VERY new at these things and I apologize if it's a rediculous idea. Also, if it isn't a good idea, what would be? And last, what would be good places to have the ports/woof…

I was just asking because on the ups tracking label it says 40 pounds(not shipped yet Just label). Or do i go off the site were it says 55.

finally, something done the right way. i just hope they now go on to create a law that is constitutional and actually does what it should, which is take care of the pricks that bass heavy in neighborhoods, disturb the peace, etc. http://www.orlandosentinel.com/news/local/os-loud-music-law-unconstitutional-20110512,0,4161161.story

I was wondering why subwoofers use tinsel leads to carry the current to the voice coil. Wouldn't copper be better because the resistance to electricity flow is lower? What makes the tinsel leads better for that part of the sub.?

I plan on getting some new equipment in July (happy birthday to me ) but I'm having some trouble deciding what I want to do first. I plan on changing everything that's currently installed, except for probably my HU, so this is going to be a slow project (lack of funds, FTL). I honestly have no idea what I want to do. The only thing I know is that I want to keep the sub enclosure small (around 1 cube) and power on the lower side, but I still want it to get decently loud. Budget will be between $250 and $300. A few scenarios I've come up with are: 1) A Sundown SAX 125.2. I'd run my Shiva off it for now, and later on get a Sundown SA-8 and custom ported box. 2) An IA …

I have a sundown 1500d and stock electrical right now ... and it probably wont change to much im looking into getting into bassracing ... ive heard a little about it but i want some information on it ... possible box/woofers/etc. i have a focus hatchback so i know its capable of hitting solid numbers with the vehicle... i really have a budget for woofer and box .... around 400 dollars ... if you could alittle help would greatly apprieicated, thank you fellas

how much would you guys pay for a billet alluminum subwoofer grill to fit your sub no matter the size or shape it is.... i can have them made but there a little pricey, so im trying to get an idea on who would pay to have them... im going have a few made plus if someone wanted something else on the grill i can make it for a little more, so it would be one of a kind.... remember this is billet aluminum not no cheap plastic so the price of the aluminum and the cost of useing a C-N-C machine is not cheap, but if i have a few orders i can get the price down... jamie

Someone wants to trade me a 1990 240SX for my truck. Was wondering if anyone has really messed around with the audio in one. Curious if its easy to get it to sound good or loud, and how easy or hard it is to take the interior apart for sound dampening. Also, how much room is there? I wouldnt need the rear bench seat, so it could be folded down or taken out all together. Its a fastback hatch, not the coupe. Is it easy or cheap to get a hold of high output alts for them? If I would get it, my SA-10s would be going in it. Possibly add a couple more, or sell them and get 15s. It would be my toy vehicle, so Id be looking for loud, not SQ.

Hi I'm in New Zealand and looking at opening a car audio shop in the future, will mainly focus on car audio retail and installs, in mid range - high end and also car alarms, tining etc. Tossing around names/ ideas of a shop names. Must be professional and not already be used. Any ideas?

I want to build a box for 2 12 inch pioneer ts 3002d4 subs. Any ideas to where i can find either a blueprint or measurements for a box?

basically, i've had a major drop in bass in my car. i have 2 fi BLs and 2 kicker 1000w amps. initially, i had trouble with my iPod cable(dock to aux cord , the 7$ one from ebay) so i bought a new one. well now all of a sudden, my cds have also lost the quality. the stock speakers in the door hit harder as of right now. when i turn the knob all the way and put the volume up, i finally get what i should be getting at about 1/4 turned. i looked at the amps thinking 1 of them was dead and they both were fine. i dont really know much about wiring but will probably read up on it 2morrow since i will have some free time to look at it, but this is what basically happens http://pi…

I looked at both company's products and was a little baffled as to why AA would want all of their subs to have a 1.85 ohm(3.7 since all of their subs are dvc) whereas FI's products are 2 ohm/vc respectfully unless FI's are the same but just secretly rounded. I used the calculator on http://www.the12volt.com but couldn't get the AA's to come out to an even ohm no matter how many woofers are added to the mix.

After only 1 year my JBL component tweeter died. I am officially done with made in China garbage, this set wasn't even cheap! I replaced them with an MB Quart RVF 269 set I found at a local shop for $140. Made in Germany is on everything, even a sticker on a bag of hardware! This set sounds way better than the JBLs for half the price. I wished they were silk tweeters, but I guess you can't have everything. Now I need to save up another $150 to get that DCON.
