Amplifiers / Head Units / Processors / Electrical

I am getting a lot of different noises coming out of my speakers. I have had this problem for a while. I thought it was my pioneer head unit but I guess that proved to be false. I have installed all new grounds and everything is wired correctly. I am getting not only alternator whine but ... noise from when I turn my fans on (ac/heat etc) and the noise increases as I increase the fan speed noise when I turn my signal light on or yield lights on - they noise pulses to the clicks of the signal lights noise when I turn my interior lights on and as the lights dim the noise dissipates. The wierd part is, if I turn my car onto accessory the noises are no longer there. These no…

Is anyone out there running lot's of power (+2KW) on a stock electrical system?

I've been doin some research about this so if i make a mistake, let me know. I got a chart from the12volt that lets me know what inductors and capacitors to use for a desired slope and roll off and diagrams for slope configurations. I also know what VDC one should shoot for based upon power used. Now, i would like to start studying the parts themselves. I'm starting with capacitors first. From what i'm reading, for high quality, low distortion use, to use caps that start with poly-... preferably polystyrene film caps. I would like to purchase all my parts from partsexpress.com and these are the ones they offer- Audiocap Theta Polypropylene Film Auricap Metallized Film Day…

Does anybody know where the brand Hifonics is made? Thanks!

I just ordered 2 d3100s for the back of my suv. I have 2 runs of 1/0 running from the front battery (d6500) to the back. I am running 4 sundown 1500s, a sundown 50.4, and a sundown 125.2. What would be the best way to wire all of this? This is what I had in mind: Each of the d3100s would get its own run of 1/0 gauge directed from the front battery. I would run 2 of the 1500s to 1 d3100 and another 2 to the other d3100. Then I would hook up the 50.4 to 1 d3100 and the 125.2 to the other d3100. Does this sound like the best possible method?

well i got my SAZ 1500d in the mail a few days ago... and now i have my 1/0 gauge Tsunami amp kit to replace the 4 gauge from my old sub amp... so now i am getting ready to install it all, i was just wondering if anyone had any good sugestions on where to set the subsonic and the LPF knobs ? and i a guessing to leave the phase off.. this amp is to run my 15" Xcon.. it is in a 4 cubic feet box ported to 32 hz.... i figured there would be someone here who could get me close..

Hay guys, I was just wondering if anybody knows anybody that might or is selling two Incriminator Audio 20.1's? I live in Nashville, TN. I am willing to drive a few hours if needed. I am wanting to strap two of these on my one 18. I don't fell like paying there retail price, so I'm checking around first. Thanks for helping.

Hey all, I have a question about routing power in the car for mobile video... I have 6 items that need to be powered on the roof: 3 15" flip-down monitors, 2 sun visor monitors, and a video signal booster. Each piece of equipment has #18 gauge power/ground leads and they are fused with very thin glass fuses, so I'm assuming they draw very little amperage (none of the equipment lists actual numbers and Google searches proved useless) so I'm assuming total load I'm looking at under 15 amps or so. I have some spare 9ga wire I could run from the battery up to the headliner for power (it might be overkill but the next smallest wire I have is 18ga and I'm trying to work with w…

I currently have an mb quart dsc 4125 for 2 peerless sls 8's(does 500 x 2 bridged) sundown 100.4(tang bang mids & alpine tweets) and a sundown 3000 for 2 xcon's. I was doing some measurements in the trunk of my acura tl while laying down deadening and there's no way to fit those 3 amps, 4 cube box, and a big battery so i need smaller footprint amps. what i need is 1 4 channel that can do 300+ bridged @ 4 ohms(pdx is an option, though i'd like something smaller) 1 4 channel that can do 100-125 x 4 @ 4 ohms(may pick up an arc audio mini) 1 mono amp that can do 3000-3300 @ 1 ohm

I am posting this topic for a friend. I cannot figure out what is wrong with this thing. Here is what is going on. Voltage remains steady. When subs are off the front speakers do not cut out reguardless of volume. When the subs are on the front speakers cut out at higher volumes. I disconnected one speaker at a time at the amp and ran each speaker separately and they front left cut out when connected and the front right cut out when connected. I checked all the connections near the amp and everything seems to be fine. The gains are also set below normal. What could be wrong? The amplifier is not bad because it would have cut out with the subs off.

Tomorrow i should have my my SAX 125.2 wired up to my Kenwood DNX-8120 and Hetrz HSK 165.4 components. I wanted to get a heads up about about all of the settings on the amp and where everything should be set. I dont have a DMM if that matters. Thanks for any help! Here's a picture for reference...

Hi everyone and Happy New Year! I need a some help finding a H.O. alternator for my 2000 ford taurus. My amp is a zx1500.1 which i have running at 4ohm to my FiQ(upgrading to an xcon). I cant really crank it up without the amp going into protect when the bass hits... Does anyone know where i can find one? Seem like every site i go to has alts for other cars except mine.. If there is any info needed about my system ill answer as best as i can.

I recently installed another amp and some 6x9's in my car along with my existing sub amplifier, I have some obnoxious engine noise going on now that wasn't there or noticable before the install. My power wire and RCA's are ran on seperate sides of the car, The amps do have a common chassis ground in the trunk. Is the engine noise because of the shared ground? If you need anyother info please let me know. Thanks for the help.

hi, im new to this whole forum thing but i need some help. i recently purchased 2 15" incriminator lethal injections and have them powered by a hifonics 1600 watt amp right now, im wanting an upgrade on my amp and extra battery and need some help on making a choice.......my 2 choices are the sundown saz-1500d or the rockford t1500-1bd......i also need an extra battery but dont know what brand....please help me out if you can....also would like to hear of any other amplifier options you may have. thanks

Ok so I got 2 major questions. Lets start off with the first one... So I have been doing some reading and trying to understand batteries, amp hours, CCAs, and such. And I am lost.... I even watched that youtube video someone posted explaining it and I just was overwelmed with all the math/info. So here is one question for ya. 1st vehicle is a 1999 mustang GT. It has 1 4awg positive run to the rear and split in a distro block to a jl 300/2 amp and a phoenix gold zx350 amp. Ground in the trunk is also 4 awg as well. The problem is the lights dim. But when I hooked up a DMM to the battery in the front it read 14.4 volts and would drop to 14.1 at the lowest with the sub hitti…

I was about to place an order for my big 3 wiring and the ought gauge wiring for my my 1200D. Really dont want to order a surplus here. Trying to keep the price low as possible. The amp combo kit that im getting comes with 17 feet of ought gauge. I am sure that it wont take 17 feet to reach the amp so I may have some left over cable. Not sure how many feet it usually takes to do a big 3 in a engine. Any thoughts would be nice. I am considering buying 10 extra feet. If you think I can do it with less that would be great. also thinking of getting x2 of these battery terminals LINK to terminals. I am assuming the big 3 will take 1 cable for the alternator, the amp will take …

this weekend i worked on the car some. i installed my voltmeter, when i installed it it said "LO" figured cuz the car wasent on well i was working on it and the batt drained some. so i hooked up a charger and let it charge well i finnished wireing my active front stage and my sax100.4. when i was done i turned the car on and i had nothing playing at all. volt meter went up to 11volts, i drove around and the highest it goes is 11.4. i have the big 3 done. i have an optima g35 under the hood 720 cold cranking amps. when i stop at a red light it drops down back to "LO" witch is under 10 volts. i have an 06 envoy. when i was running my wires and installing everything i notice…

i just had some weird dreams i was being bitten by blackwidow spiders on my left hand and woke up in a panic. (i'm terrified of spider). so it lead me to go to soundstreams website to look at what kind of amps they offer. i see this D tower thing looks pretty sweet. anybody have any experience with it? i found a place on ebay that sell is it for 328 each. they only problem i really see with it is you cannot lay it down. ebay D-Tower also that cant be right... can it? direct 4 awg power?!

whats the opinions on the newer MB Quart amps. i know galamonkey uses them and ive seen alot of others with them. Im wondering if they share the same boards as the autotek mean machines. they seem very similar, especially being that they are both crappsonics brands. they are tempting bc you know the name used to be good and you can get them for so cheap on ebay.

I know to add up all my amps fuses and the total is my in-line fuse size. My question is about fusing at the db block. I've read in a previous thread on here to fuse under never over( i.e. 180A = 150A). I have an amp (US Amps USA-150) that requires fusing at 75A. It has 2 inputs for positive and 2 inputs for the ground wires. Can I use a 40A + 30A = 70A fuse in my db block or will it affect anything being different sizes and under the fuse rating? Thanks and have a Happy New Year!

I ordered my 270 amp alternator from Dc Power Engineering on 12/18/09. They got my payment and I have yet to receive any information. I've called them and left messages with no avail. For the people who bought alternators from Dc Power Engineering how long has it taken to get a shipped notification? It's been almost two weeks and I'd like to get it in (Who wouldn't?). At first their customer service was Grade A but now i'm starting to see its not as great as i thought. They say they'll return calls and such. Even if they didn't have any information on it it would be nice for them to call and simply say "we don't have any information". But I guess it will be another week…

Blue one: http://tinyurl.com/ybem7ro Red one: http://tinyurl.com/ybndc95 just ordered mine.

i got a soundstream sa-164 a cpl months back its in mint cond. was it worth the $40? also what yr were these made also i recently traded a pair of 6x9 boxes for a brand new alpine mrd-m300 v12 i like how it tell u the volts, current ,an temp. i have it hooked to a pc power supply in my room and it will jump up to about 11.0 amps before it shuts off the power supply. my alt. in my car is bad so i havent tried it in there yet. now my ? is can anyone tell me the average amps it might pull at 14.4v? thanx in avance

I have 3 of the old rockford 200x2 transana amps 2 of them i bought from a guy that swore they worked fllawlessly. Anyway I hooked them up to test them out, they paly fine until they have to play a low note, and then they clip i guess, until i turn the volume down a little and then they play fine. The other 200x2 I have doesnt do that at all I can play it all day long and it never does that. has anyone ever heard of such a problem?

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.
