Will a aq750 be able to run at .5 ohms?

I recently bought a 3000 watt audio pip class d mono amp and running it for less then 45mins destroyed my stock alternator. i currently have a 130amp alternator two normal car batteries one in front and in the trunk. every thing hooked up with cheap 0 gauge wire (its not ofc), and i don't have a big3 upgrade. clearly i need to do something before i hook my amp back up. i was thinking either a big3 and big xs battery like a 4k watt one, or a high output alt and a big3, or something. What would you guys suggest? Thanks in advance for any replies i dont know if it makes a differnce but i plan on running either a ssa zcon or a sundown z series 15 in a home built 3cubic feet …

what does everything think of these? i had the 1500 watt version early in the year running 4 ohm on an old school eclipse 12, never ran hot, had no issues with it and i loved the small size of it but people either love it or hate it. i only ask because audiopipe came out with a new 2000 watt model and it looks promising as does most AP products due to cost/watt ratio. looking to actually compete this next year in street stock and street trunk. I'm working with a budget of about $400 for an amp. Ramrod and i have been talking but i also want to get some input from others in the competition world. will end up running either 2 12 gcons or icons. just waiting on the w3s i hav…

Wanting to add to my existing alarm, thinking about adding perhaps two exterior sirens, current one is hurting. Also like the idea of having one or two piezo sirens inside the cabin. I have seen these refered to as pain generators. Any of you have input on particular brands which might stand above others in performance? I also wanted to know if adding the additional sirens and alarms will require any additional wiring aspects, I guess I mean can I just wire multiple sirens or will I need additional installation knowledge or products? Thanks for your help and input. Chop

Hey there! Just a question, I know amps get hot, but i think mine gets too hot. It will get hot enough to burn the shit outta your hand if you touch it and count to 3. My question is, why? and can i prevent/stop this. I thought the problem was because of its location, it was under my seat, so i moved it out in the open thinking it would get more air and stay cooler. But i was wrong. It gets this hot on my way to and from work, so day and night regardless of outside temp. maybe 30 minutes of play. Its this amp - http://crunchusa.net/Crunch_PowerOneAmp.html the one in the picture. 2050.1 and i have 2 IA Lethal Injection 12's D4. My voltage never drops below 12, never. Any i…

Ive been looking at DC alts for my truck and they go from 2005-2009. The 2010 is the same gen and engine as the 2005-2009 im guessing they just left it off the list by accident just wondering if anyone knows for sure if it would work or wouldnt for some reason. thanks in advance.

i've had my system hooked up for several months now and just decided to add a rockford 360 line driver. i hooked it all up with the remote wire to the rockford 360 tied in with the remote wire to my amp. as soon as i started turning it up my amp went into protect mode. so i took i guess at that me adding the remote wire to my amp did it. so i moved the remote wire to one of my secondary batteries just to see and it still throws it into protect mode. the voltage doesnt drop it will just go itno protect mode. any ideas or suggestions? just incase you need to know what i have system wise 2 18'' HDC3 audioque DC power high output alt 3 batteries in the back (2 kintik HC1200) …

I've been looking around for a good 4 channel amplifier that cost some where around 350 or less that has a small foot print I was hoping to hide it. I have looked at the rockford fosgate pbr 300.4 was wondering if anyone had any experience with these? Or if anyone has had any other amps that are on the smaller side I would like to hear some other options as well. Also I was wondering if anyone could tell me where I could find some info on the little soundigital 250.2 I tried emailing them and messaging a soundigital rep on the smd website and got no replies. Was thinking of maybe getting 2 of those for running a set of comps. could definitely hide those somewhere.

So, i'm looking at getting an aftermarket alarm system for my truck, but not sure what to get. I want to get a good one. But only problem is, my truck dont have no power locks, just manual locks, or that wont really matter?

1st off let me say that a dd1 is not currently available anywhere around me at the moment. And I just got my system installd so I wont be able to afford a dd1 for a month or 2. Also no shops around me have a scope (dont ask me how they set their gains). So I have to temp DMM set it. Question is ive read alot of people saying to set it to the HU preouts which would be 2volts. Even on volume 29 the gain is pretty much all the way down at 2 volts. Or do I set it from the watts/ohms chart that ive seen around the web? Which would put me around 38-42volts? Which of the 2 should I go by? Also what setting do I set the DMM to, I know its Vac, But is it 200, 2000, ... ? Any info …

I am gong to be getting 4 Rockford fosgate t2500-1bdcp's and im wondering if there was a way to calculate exactly how much power I will need. I am planning on getting 2 DC 300 amp Spx alternators and 5 xs 2700 Batteries. will that be enough or does anyone have any other suggestions?

Hi, Im about to start a build in my 2003 Dodge Dakota, Will be running a Crescendo BC2000D to two 15" SSA ICONS and a Rockford T15004 to a set of Hertz HSK components and probably 2 8" or 10" Crescendo Mids. Have an XS Power D2700 so far just wondering if at this point getting A 250 amp Singer alternator or a second battery ex XP2000 or XP2500 would give me less voltage drop or if its even necessary with that power? All wiring is Knukonceptz Kolosses 1/0 Gauge 1 run - one run +. Also any advice on personal experience with people running Crescendo mids along with a high end component set? Thanks,

I am going to be getting some hertz 165xl components and am considering running them active with a nice sound processor. The problem is I don't know much about sound processors or running speakers active. what should I look for when buying a processor? is it worth it or should I just use the crossover that comes with the speakers?

a friend of mine is looking at getting a new system in his grand prix. so im gonna to hook him up with a dcon 12 but i need an amp that will run it safely. maybe a 500w @ 1 ohm. or a 1000w wired down or something along thoes lines. let me know what for amps i should look at but his price range would probably be around 300-350 for everything.

I am thinking about purchasing a Rockford fosgate 3sixty.3 but I am wondering if it works with apole laptop. this might be a dumb question but I just want to make sure. I would like to program it through Bluetooth with my laptop.

I have been wanting to put a mac mini in my car for a while now but still have a few questions. First off, would I need a head unit or could I somehow just use a amp and a sound processor? If so how would this be done? Second what are some good 10" touch screen monitors that will work well with a mac mini?

I recently installed a Pioneer AVH-3200BT in my new car. I've been having alternator whine issues, and I've been trying to figure it out. I thought it may be the pico fuse at first but the head unit still has connectivity between the chassis and rca shield. I tried a ground loop isolator and it made it worse. I ran a new ground direct from the head unit and the whine went away, but a static remained. At first it was bearable, but it's gotten louder for whatever reason. At one point today when I was troubleshooting it today, I removed the ground wire and the head unit stayed on! Confused, I tried to figure out how it was grounding, and it turns out it is grounding through …

I was thinking about my wiring set up today. In my new vehicle I have yet to do the Big 3, but I do have a dedicated 1/0 ground wire that goes from my back battery to my front. Is it really necessary to do the big 3 if you have a dedicated ground? I can see the upgrade being useful if you are using a chassis ground because your return path would be limited to the chassis to battery, but if that is elimated is there still a benefit? As far as resistance for the power wire goes, lets say the wire from the alternator to the battery is 4 feet. The stock wiring is 8 awg, which in general has a resistance of 2.061 ohms/km. This means the resistance of the wire is 0.00251 ohms. …

I'm thinking about doing a double din conversion on my 02 Silverado and was looking at the new soundstream/ power acoustik ingenix series double din. Do yall think that it would be a decent head unit without spending too much? Or would it be worth doing the conversion for?

Hi guys I've been looking around at some mids and highs. I'm thinking about trying to run 2 6.5s an 2 tweeters in each front door of a 03 ford explorer and maybe some coaxials in the rears. My question is what kind of amp should I run a 2 channel or a 4 channel? It's seems the 2 channels are usually quite a bit cheaper. What are advantages of running a 4 channel?

So I was browsing the classified looking at all the junk that people wanted a ton for when I came across this. Even better was what I paid. Just wish I had a use for it, its been sitting in a closet for years I was told, its got some scratches but its a huge beautiful amp. Please bear with me as I have never posted pics on a forum.

Hey everyone, just a simple and quick question. Is there any real difference in the two types of fuses other than the fact ANL typically has a higher current rating on it? I was wanting to use a 120A AGU fuse for my setup since the max draw of my amp is 120A, but I just wanted to know if there is any real difference between the two. Thanks!

I'm planning on buying a new starting battery for my suv. I'm running sa15's on a hifonics brutus elite 1600. I plan on doing the big 3 in the process. I just need to know what would be a good battery to put up front. I would like to do the big 3 and a new battery up front and then put a second one in the back. My budget is around $200 give or take

I may need to order some wire specifically for tight areas soon. If i do, has anyone actually used both of these before? I know Kolossus Flex is so flexible it feels like there is no wire in the jacket... But i do not know how flexible they have made the 4/0 in RE... My runs would need to do an "S" in about a 6" range.

Im running a crescendo 3500bc at .5ohm looking to make shure im getting the most power with the least resistance, trying to invest in dual 1/0gauge inputs but unsure which one's will fit. Down between three of them but im unsure even if either of them fits correctly. http://techforcepcse...php?productid=4 First one tool maker like this one because the copper option. http://www.teamproje...0-adapters-pair Second one is projectdb. Other option they offer is http://www.teamproje...0-adapters-pair
