so i got a 4' x 8' sheet of 3/4 plexi for free the other day so im using some of it to enclose my amp. im wondering where i should mount my fans i have 2 4" fans and im wondering how should i mount and wire them. 1 in each end? wired one pushes and one pulls? or both pulling air in? and ill add 2 more when i find some more

I need a new amp for my SI Mag. I had a Massive P1000.1 amp running it that does 880W @ 1ohm, but that amp is now powering my newly fixed Adire Brahma MKIII that Fi reconed for me and instead of getting a new amp for the Brahma, I'm thinking about getting one for the Mag. Now here lays the Problem. I'm down to these: Sundown SAE-1000 (1000W @ 1 ohm) - because I know Sundown is high quality. Massive P1500.1 (1250W @ 1 ohm) - because I've never had a problem with the P1000.1 in the year I've used it. and Hifonics BXi1206D (1200W @ 1 ohm) - largely because it's easy on the wallet. I won't ask which one I should get. I'm pretty sure EVERYONE's going to suggest the Sundow…

I was planning on getting two of these for the 2 BTL 12s Im getting but I looked at the pix and I didnt really notice any fans, does that mean I have to be weary of over heating? Ive had problems with amps doin that before. Also would it have a pretty good or just eh sound quality? Id be using it in a daily set up so yea.

So i got my 3500 v2 and hooked it up (post pics in just a min) im planning in running it on my SA-8 v2s for now @ 4ohm until i get my 0ga and mojos in. it should be be fine cause its not pulling more current than 4ga can handle right? also i ran it at 1 ohm for a moment and carefully increased the volume and i realize its not any louder than my saz-1000d was and watching my voltage im not getting any drop at all at idle. could there be something wrong with why its not pulling any more current than my saz-1000d was assuming it should be pulling way more? just confused at why.

I am doing the big 3 on my 2004 Rodeo and have ran into a slight snag. I am hoping somebody on here has some advice. I am using 1/0 AWG weling cable from Airgas (Radnor Flex-A-Prene) . I Grounded the negative battery terminal and the engine to the chassis without issue. Now I am trying to attach the cable to the charging post on the alternator. The problem is that the charging post is a tiny bolt, and the lug on the welding cable is huge (http://www.airgas.com/browse/productDetail.aspx?Category=14&product=RAD64002143). The lug is too thick to be able to re-attach the nut on the charging bolt, and it is coming in contact with the case of the alternator where …

does it matter how far the fuse is from the battery, as long as it's within 18"? more specifically can it ever be too close to the battery? i installed new wires in my friends car (power and grounds) and its only about 6" from the battery. his fuse keeps blowing so he tried a bigger fuse (still only 80 amps) could that be the problem? i dont know the specifics on what amp and such but its probably 7-900 watts. should he just upgrade to a 150 amp fuse? its 4 AWG.

so i got: optima yellowtop under the hood kinetik hc2400 on the back iraggi 240/165 amp alternator it was running fine for about a week since i installed it, my voltages were: 14.2@idle, 13.4v w/ engine off this morning it was running fine too so when i was leaving this afternoon, i noticed the battery gauge was pretty low i checked the voltage and it was only 12.7 while the car is idling and system is off so i turned my car off and checked the voltage, it was 12.8 so i disconnected my powerwire that runs to the back battery and the amps after about half hour driving i checked the voltage, while idle it was 12.3 when it was off it was 12.5 what do you guys think? did my …

Found these on ebay because I was bored at work. They say the one for my explorer is a 250 amp and will do it @ 1200 rpm. for $170.00 free shipping. Anybody ever ran across/used them?

Ok i shoulda took pics, but hey.. So i have it hooked up @.5 ohms and well yea this system is alot louder than my PA3000db. but i have a slight problem, i'm guessing its an electrical issue, but... I can only turn the system up so far before a big bass note hits and its like the amp goes into protect and then comes right back on, say 2 secs later. SO is it wiring or electric? I'm going to hook the battery charger up to my car to check but any ideas? IT wangs dont get me wrong, but i just cant turn it up louder than a certain point..

Pioneer Premier P880 PRS, easily the highest end deck i've ever bought. 24bit dac's, l/r seperate eq's, 5v outputs, a ton of xvoer points. here are some pics.... http://www.sonicelectronix.com/pictures.php?id=6822

So I just picked up a 2005 TrailBlazer and the factory Head Unit has to go.... I have alway like Kenwood head Units so, I'm looking at the Kenwood DDX514.... http://www.crutchfield.com/p_113DDX514/Kenwood-DDX514.html?tp=20217 It seems to cover most of my wants... Nice Bright easy to see/read display in all lighting conditions. If its going to have one, it might as well be good! Ipod control, not just Aux input, but seemingly native controls with Album art, playlists and all (need a 30.00 cable) Ability to hook up an HD tunner (extra 80 bucks I think) Ability to hook up a Sirius (again Controls it natively, not just a aux input) (I have sirus and love it for travel) Abil…

Hey guys quick question: I understand this: Voltage of the output = sqrt(RMS Power X impedance of the speaker) Example Say the amp provides 100WRMS into a 4 ohm speaker: Voltage = sqrt(100W X 4 ohms) Voltage = sqrt(400W*ohms) Voltage = 20V So I have a 1500W amp and two dual 1 SSD12s. Would it be? Voltage = sqrt(1500W x 1 ohm) Voltage = sqrt(1500W*ohms) Voltage = 38.7V Should I use 30HZ, 50HZ, or 100HZ tone?

I am currently running an alpine 7995, at this point it is the cleanest deck I have ever heard. Has anyone heard one of the new Panasonics with 106 db S/N and 5V preouts, or does anyone have any other decks they would recommend?

ok so I installed my singer 250 alt amp and did the big 3 using knu 1/0 ofc. . the volts with nothing on stays at 14.6. I can turn it up full tilt and it ranges from 13.8 - 14.1.. So my question is why do my headlights still dim? It's not on every song either. I can play tech n9ne so dope or TI on purpose and its perfectly fine. I can play something with alot less bass like lil wayne god bless America and it looks like a light show. Am I going to have to break down and install a couple batteries or what? trying to avoid it because im running out of room. oh, im running a 12 inch zcon on a crescendo bc3500

pretty much like the topic says i just want some opinions how many batts should you run on 2 SAZ-3000d's with a 225amp alt ?

Kinda new to this but just need an idea as to what I need to upgrade on my truck to run my 4 15s 600 watts rms 1200 max I got a 3k amp coming and 0 gauge wire my truck is a diesel so it already has 2 batties and a 110 amp alternator from the factory. I just want to make sure I don't have to worry about power loose. Anything helps thanks.

throw out some budget amps thatll do around 2500w rms @ 1 ohm daily, will run @ .5 or whatever if its stable daily...its for my 15" mts...i have 4. i know the power acoustik a3000db is rated at 2300w and doesnt even do that, but i heard they are .7 ohm stable daily, does anyone know what these amps are capable of? hifonics? help!

For Black Friday I found a great deal on an iPad mini and want to use it as my new head unit. I have done some research on how to hook it up and now have a few questions. I found the iStreamer that takes the signal from the iPads USB connector and converts to RCA but right now that piece is way out of my price range. So instead I wanted to use a 3.5mm to RCA output to run my amps. What I was planning was running the 3.5mm to RCA into the aux input on a Clarion EQS746 and running each output to its amp. Front going to my tweeter amp. Rear going to my mids amp. And obviously sub going to my sub amp. Will the EQS746 act as a crossover so I can control my system actively out …

Ok i need to know which one of these amps are the better one to get (am running a 1 ohm load). I narrowed it down to either the Autotek MM 2000, the Soundstream PCX2000D or the Soundstream TRX2000D. I would like to hear from anyone who heard these amps. And which one of these amps do rated power or is closes to rated power. Any input?

I'M NOT SURE IF ANYBODY CARES BUT I JUST GOT OFF THE PHONE WITH BRIAN FROM MTX AND HE INFORMED ME THAT MTX WILL BE RELEASING A 3000WATT @ 1OHM AMP, AT THE BEGINING OF THE SUMMER...I DONT HAVE PICS BUT HE SAID THAT WILL BE FAN COOLED AND THE AMP IS 2006-CEA COMPLIANT...SO IT WILL PRODUCE 3G'S @14V...HE ALSO TOLD ME THAT, THE AMP IS UNDERATED SO IT WILL PRODUCE ATLEAST 3200-3400WATTS@ 14V. AS FAR AS THE JACK HAMMER...THIS THING IS 22INCHES WIDE 23INCHES DEPTH...ITS NOT MADE 4 ALL CARS...IT WILL HAVE 2 REPLACEMENT CONES...ONE FOR SPL AND ANOTHER FOR SQ..AND BELIEVE IT OR NOT IT ONLY REQUIRES A PORTED 15CUFT OF INTERNAL SPACE. 80 JUST GIVING ALITTLE INFO

i am currently running 1 ea.pos and neg 1/0 ga wire from the front to the back, would adding just 1 more pos run help or do i need to add the neg also and keep them even? Can you have more pos than neg? Good or bad?

So, I just but in the new BL, (see sig for more info), and I am very displeased with the amp I'm powering it with, so I think it's time for a new one. Current amp is putting out 600 at 1 ohm, (so it claims, not so sure it is), and I am looking to change that; on a $300ish or less budget I was thinking an audioque 1200d or an SAZ-1000d, (the pre-order for the sundown 1200 will be long over by the time I have the money for a new amp, so it is probably out of my price range). Are there other good choices out there? This is going to be a budget-concious set-up so if there are two solid amps putting out decent power, then I'd go for the cheaper one, unless of course it is o…

Now I was told is that you swap out your factory battery and replace it with a better battery and high out put alternator. Others mention that I should have two batteries one for the car and the other for the stereo and high out put alternator. What should I do? Also are Odyssey batteries good since I have a PCJ 12OO under the hood.
