I'm wondering why when I changed from 300w @ 4 ohms on my amp, to 600w @ 2 ohms I havn't noticed an increase in current draw. I just picked up a couple Z15s off a seller on here that listed them as DVC4 ohm, and I'm only running one of them due to lack of power/trunk space. I have it wired up to my sae1000d in parallel to get a 2 ohm load. I just pulled a 2 12s out that were wired @ a 4 ohm load on the amp, so I'm going from the 300w @ 4ohm to 600w @ 2ohm. I didn't adjust the gain because the voltage is the same at about 35 volts. But since I'm doubling the amount of wattage being used, shouldnt it be pulling 2 times as much current? The output is about the same as the 2 …

Anyone have this yet? I like the pandora idea wondering hows the sound qaulity of it.

I am getting 15's very soon. Two aq hdc3's off of a 2200d. My electrical now is a 200amp alt, 1/0 big three, and yellow top under the hood. All this is on a diesel engine, that of course runs at lower rpms than a traditional gas engine. I have the smallest pulley I can put on the alternator already installed, and am scared the voltage may not be enough to back this system. Would another battery be needed? If so which one, and for the best price? By the way, this is a daily setup.

Amps that have a clip light ie sundown is that light accurate? What's safe a small flash a little fast fashing solid red? Gain was check with a oscope and a dd1 in the past.. Still clip light comes on

which is better, dls a6 mono amp or a sundown sae-1200D??

ive had my new radio in for a few days and its great. i was going to sushi with my gf and we entered the plaza and as i hit the dip the stereo stopped playing and said protect. i did some research and i saw that there is probably a short somewhere in the speaker wire. im currently on the factory wiring for my front door speakers til i hook up my 2 ch. i have infinity kappas so they have that big external box for the speaker wire so i assumed the skinny factory wiring came loose or something. i saw that some people just reset the radio and it never went into protect again. i tired it and it worked for another hour then it went into protect again. but when it was working i …

ok so if i got 2 amps hooked up how should i ground them, so far i got a 1/0 spliced to 2 8 guage wires. its not working very well, should i get another distro block for my gound wires as well?

I am looking for 4/0 wire. any recommendations for this type of wire. and where to get it

any suggestions for an amp for a 18 BTL ????

Im looking for a good 4-way crossover for an active system. I dont want anything cheap but i still want it to be reasonable priced. Thanks Corey

I'M NEW TO THIS KIND OF SETUP SO IF I MISPRONOUNCE CERTAIN ABREVIATIONS, PLEASE FORGIVE ME, BUT HERE'S THE LOW DOWN....... I'M OVERSEAS RIGHT NOW IN THE AIR FORCE TRYING TO GET EVERYTHING FOR MY SYSTEM SO WHEN I RETURN, I CAN BRING EVERYTHING TOGETHER BUT THIS IS TRUELY MY FIRST TIME PUTTING A SYSTEM THIS LARGE TOGETHER SO I COULD USE AND USEFUL ADVICE U HAVE FOR ME. MY FIRST QUESTION IS.... 1. HOW DO I RUN MY BATTERIES AND IS THERE A DIAGRAM IN WHICH I COULD FOLLOW 2. FOR EACH ONE OF MY AMPS, DO I NEED TO RUN A SEPERATE CIRCUIT BREAKER? 3. DO I RUN THE POWER WIRE FROM THE ALTERNATOR OR FROM THE POSITIVE POST ON MY STOCK BATTERY WHICH IS A DURALAST MAXX YELLOW BATTERY? MY…

Hello I am an amateur stereo guy in need of advise on setting my amp. I have the gain set to 21 volts on the front and rear of 4 channel with a 1khz test tone I have the gain set to 41 volts on the 1500d amp with a 50hz test tone Those settings were given to me by a friend My question is where to set the crossovers? the low pass/high pass filters the subsonic knob and the 2 push in buttons I currently have the front channel run on the crossover on the head unit set to 100khz with a 24 slope Rear channel is off on deck, and set on low pass on amp but not sure what the settings should be on the amp, the deck does not give me a low pass option on rear channel The sub is cur…

I just want to learn about this amp some more, I have only seen one in a car, and the owner was not there to turn it on, so I would like to find out more

Ok, im looking for a head unit that is vibration resistant, clean output, good looking (matching my interior, ill post pics if i am asked), plays MP3's and WMA's preferably (so i can keep one CD in for 3-4Hr drives), and i would like an RCA in too but that isnt required. I only need 2 sets of RCA's. I would like pause as well (if i ever want to compeate bass race it would be nice) Im getting a $139 refund from Ikes Sound for the DEI1100D (its good because i paid $70 for the amp, send 29 to get it repaired. Im basically making $40) and soon ill have around $100 from my parents, maybe more if i score awsome on the ACT (lol). so my budget is around $240 and the above is what…

Ok well i got rid of the D3, and got a CDA-9887. LOL, bid difference i know. But before i've even done any sound setup or tweaking my subs instantly sounded better after they were turned on. But DAMN there are alot of sound options. I tried for 10 mins just to setup the HPF so i can take the bass out of the front and rear speakers to no avail. Needless to say at this point i feel kinda dumb. But i've been really busy today so i haven't had a chance to read the manual. I knew this deck had alot of options but man this is rediculous. I still have the stock hi's in my car but i plan on changing them out. And i know that everyone is going to say go ACTIVE. So before…

where can i find battery terminals with two 0 guage inputs. the only ones i can find have one 0 guage and one 4 guage.

So I have a Sundown Audio SAX-1200d, and I get a lot of dimming. what battery should I get to STOP ALL dimming?? thanks

Hey guys, been lurking for a while now (on CA.com, DIYMA and ROE more). I thought I registered but guess not. Anyway I bought this AX 5600 BNIB, I believe it is a 2006 model. Upon arrival I noticed that the Xovers were 50-500 for the sub channel, 50-500 for the "Front" 2ch and the "Rear" were able to be bandpassed from 50-500 and 200-5k. I have an Alpine CDA-9835 HU and CDT ES-6 mids and DRT-25 tweeters and a single 12" SS RL-p in a 2 cube box tuned to 32hz. I want to run the comps active off this amp. Now I'm stumped why the "Front" channel Xover is 50-500hz. Please tell me I have a fluke amp that has a typo and that really should be a say, 2000-20000hz HP filter....? Or…

first off im a 16 year old kid with little experience. ive done a few installs before but not very many. i have a single bl 15 on a sundown sae-1200d. but anyways my friend has a 1998 dodoge dakota and i was attempting to put a brand new kenwood head unit in it. and when i was wiring the after market harness to the head unit harness there were some weird wires. theres two harnesses to wire, one has 3 of 4 speakers and the remote wire on it and the other has power, ignition, illumination, dimmer, right front negative, amplifier ground, and mute. there is no wire from after market harness for left front negative but the one that says amp ground is the same color (white and…

I am currently looking into the three.1 from audiocontrol http://www.mobileaudiocontrol.com/product....roduct_Id=14149 I was hoping someone with more in-depth tech knowledge could educate me on if this product is worth my while... I have Alpine 9857 1 SS Rubicon 502 100 watts x 2 running my front comps (A/D/S 6-1/2" 346cs) 2 Us Amps MD.1D for my subs.... I am looking to get another amp to toss my A/D/S passive crossovers and run active... If the three.1 from AC isn't gonna fit the bill what would you all recommend I'm not going for competition SQ or anything just what a nice sounding daily beater that sounds pretty darn good to the ear....

I was interested in daisy chaining a pair of XS100's for each 9515. I am not too sure of how to go about doing this.

My first question when you change the bass level, middle level and treble level it controls all speakers including the ones on the amp? The levels go from -8 to 8, right now I have the bass at -6 (usually its at -8), the middle at 4 and the treble at 8. How do you tailor made these settings. My second question is the bass level has a Bass F(40-120hz, I keep it at 40hz), Bass Q(1.00-2.00, I keep it at 2.00) and Bass Extend (off/on, I keep it on). Could anybody explain what these settings should be around or what they mean (I know bass F is frequency) or if I should even mess with them? My third question is the middle level has a Middle F (500-2,000hz, I keep it at 500hz ),…

Im looking for a component set. with the addition of this 18" BTL its damn near impossible to hear high end over the bass this thing outputs.. I went to some stereo shops to see some products up close.. saw a set of the Fosgate power 6.5's.. has the driver, tweeter and crossover network.. price in store is crazy, but found the same set on the internet alot cheaper. Im concerned how they hook up as ive never had a pair of components before. Do you just use 1 channel of your amp per door.. Let me explain what i mean more.. go here My link see how the crossover box has 2 inputs and 2 outputs.. i just got done running all new wire to each door to a 4 ch amp.. will i have to c…

Hello everyone, I haven't posted here in a while, but I've been keeping myself current on the threads in the build logs section for sure. Some of you might remember my build log, and might also remember that once I got to the point where I could finally fire the thing up, I was having lots of trouble with noise. I tested and tested, and it turns out that it is my JL Audio 500/5 that's to blame (I installed another amp in its place and the problem was totally fixed). It's a high pitched beeping sound that changes evenly in frequency (up and down). Sometimes it actually sounds like a pack of dolphins from the nature shows... very bizarre. It makes this noise in all chan…

just wondering, if there is any mainstream manufactured gadget for converging multiple 1/0 into a single 1/0 input like that found on the stesom amps. i'm looking for maximum flow/least resistance for an instantaneous dump of power for a single burp. this'll be a single 12 on 2 stetsom 7k e's in a crx. i know others have custom cnc's things, or buss bar type feeders, but just seeing if i can get away with not fabricating something.
