So I currently have a d2 icon wired to one ohm in a ported box running off at sundown sae 1200 v2. I also have 2 fi ssds d1(s), I built a sealed box for them and wired them in parallel; on the dmm it reads .7 ohms. My vehicle is a buick lesabre which has 130 amp alt. With the icon my electrical is great, the lowest i see is 14.0 (13.8 or so with the a/c on) at full tilt while at a stop light or something. I put the fi's in, a direct swap. I left the amp setting the same. My voltage is horrible, dropping into the 12s at full tilt at highway speeds. So i turned down the gain, pretty much a 1/4 turn back and my voltage is just as bad. My lights flicker horribly and the volta…

So i went to my local shop and had them do the big 3 for me, yeah i know i should of done it myself lol. Used that Knuconceptz 0 gauge wire. A buddy of mine told me that I will need to add an additional fuse to put between the alternator and the battery, but the shop said that it wasnt needed. I think my alt is like a 130amp on my scion tc, and the extra fuse i bought says 300A. Big 3 helped the voltage a bit, but it still drops right away if im giving a demo or just bumping it loud to the upper 11's. Check the pics here, ImageShack Album - 7 images All i see is the alt to the battery, then the battery to the ground. Is it done right or do i need to add that fuse that i…

Well, instead of posting all this in the build log, i'll just post it here because i have a question anyways. I have\had 2 of these amps strapped together. When i first strapped them up, after several minutes, the slave went up in smoke. It was concluded that the input stage on the amp got damaged. There was no audio coming through either amp when i first tried using these. I tried using just the master. No signal at the time until i unplugged the rcas from the HU then plugged em back in... been working ever since, odd but no probs now. Got the slave amp back in and i did not have any subs hooked up to em when i had em strapped again but the slave amp went up in smoke …

I just installed my new HU, it's a Pioneer DEH-P690UB (not the best in the world, but it gets the job done). It has a usb connection to hook up your iPod and other usb mass storage devices. My question is what brand/make of HDD works? I've already tried a few and they are a no go. Reason is I think they are requiring more juice then the usb cable can provide. So if anyone can point me in the right direction and stop me from wasting more time and money trying out different usb hard drives I'd really appreciate it.

I have an 86 crown vic with a kicker 300 watt amp powering an IA 187 15. When i have the volume or bass up i get some very noticable dimming from my interior and exterior lights. I think the stock alternator is only a sixty five amp. What i want to know is will this up grade help my dimming, and what exactly is it. I know its replacing wires with larger wire, but what wires should be replaced and how big should i go. I tried using the search feature but i guess its idiot proof.

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 got a second hand kicker 750.1 a while back, pushing two 10 inch Kicker CVRs (400rms each) wired to 2ohms so the amp is giving about 750rms. Today, my new amp came in, the Hifonics 1700.1 (1700rms at 1ohm, 1200 at 2ohms, 600 at 4ohms) I wired up my old kicker subs to it, same wiring and boxes, so they should be getting 1200rms instead of the 750. On the kicker amp, i had the gain right below half way, on the new Hifonics amp I have the gain turned right around half way, and it sounds the exact same. Why do I not get any difference with the added 450rms? This setup is also only temporary, 2 Sundown E-12s wired down to 1ohm will be in soon, as soon as I finish the bo…

So i know hifonics isnt the best of companies, but ive heard mixed opinions about the 2008 brutus amp lineup as to whether or not it does rated power, I was wondering if anyone knows for sure what they output(specifically the 1608) or has any birth sheets/ done any bench testing. If not what do you think the bxi1608d does at 1 ohm and at 2 ohm, it claims 1600 at 1 and 1100 at 2...

Two questions 1) Does the AQ2200 have a regulated power supply? 2) Would the AQ2200 be able to run 2 FI Q 15's with BP power, or would that be too much power for the subs? Thanks

ok guys im starting a thread here to discus some real cheap amp, new and used, that would be acceptable for a budget setup like mine. also, the new option must have some significant advantages for justifying the purchase. i have to run off shortly so i cant type up to much right now. what i have now is a kicker zx100.2 and kx250.2 powering sls8's and peerless 3" full range. my dad is interested in the 100.2 for 30 bucks (baught for 50) and my bro is interested in the 250.2 for 70 (paid 90) and im willing to throw in 100 bucks tops for a $200 budget. some things that id like to get out of this are, 1 a good quality amp that i can expect to last thru college (3 years), …

I recently got a nice deal on two used mm1400.1d's. Now i'm considering running them together on one BTL 12. Does it matter if one has a little more wear and tear than the other? Will it be okay as long as i check that i have the amps sending the same output wattage with a multimeter? Is it a bad idea all together?

Say I have an amp that has 2 power and ground inputs. Say if I just use one with twice the size power wire is that ok? Or is there some important reason that they are split up to begin with? Fast advice is appreciated.

Hey guys, i'm looking for 1/0 gauge wire for a big 3 upgrade. I was researching some wire and it seems that 1/0 is pretty damn expensive. I stumbled across this brand knukonceptz which was the cheapest, and i had to post something to get feedback, because i noticed in their description that their wires are made up of 90% aluminum and 10% copper. Now for an amplfier i wouldn't care, but i'm pretty sure for a big three upgrade i'm looking for least resistance, and that wire is basically all aluminum. I'm not trying to bash the company, but would you guys recommend this wire for a big three upgrade, or should i go off looking for something that has pure copper threading in i…

I will be installing this tomorrow.

I'm in the market for a new HU(since the mazda 6 kit is almost out). Here are my requirements: - at least 4 volt pre-outs, including one for sub - crossover for sub/mid/hi - red illuminated buttons or at least majority red illumination - would like it to be a silver color to match my dash but not necessary - mp3 capability I'm trying to gauge my options right now, and no price limit.

So I have a SoundStorm (SSL) EV4000D. I've had it for about a year and a half, and never have had a problem with it, except that I have blown two Subs with it. The first one was a Pioneer TS-W3002D4 which lasted about 8 months and then the most current one which blew today was a Kicker CompRT12. So i need suggestions of what kind of sub i should get because obviously the last two were a fail. I want something that will thump my price range is up to $250. Hope I can get some feedback.

Had to disconnect my radio for trouble shooting and when I hooked it back up with yellow to yellow red to red it dosnt wont to power on unless it's hard wired yellow to red.. I have a extra orange (illumination) wire left can't remember if it was hooked up or not please help so I don't have to take my deck out everytime

I'm planning adding some some battery terminals from knu konceptz, but there are about 3 smaller (stock) cables currently running to the power terminal now. Could I just combine all these and use them in one of the 0 gauge ports of the knu konceptz terminal? And then leave the two remaining 0 gauge ports for big 3 cable/amp cable? thanks.

Are there really any half decent HU's these days? Originally I was gonna go with a Kenwood eXcelon KVT-696. But I don't need a DVD player. I would have had this system done by now but I lost my job back in Jan and just found one. The rest of my system is: Subs: 2 IA Death Penalty 12" Dual 1 Ohm Amp: Sundown SAZ-3500D Speakers: Im still not sure. But leaning towards Polk speakers Speaker Amp: Kicker ZX350.2 Sub box: Probably something between 4.5-5.0 cuft net @ 33Hz My alt and battery will also be upgraded too. This will be going into a 06 Dakota Extended Cab.

Hey all.Im going to be getting a AudioQue 3500d.1 and I was wondering about the dual power/ground inputs on the amp.My main question is a major noob one.How do I hook the amp up with the dual inputs?Like do I need a distrobution block for both power and ground or do I just run both power/ground inputs to the power/ground inputs on my rear battery or what?My second question is about adding a 3rd battery.Ive been searching the forum and I think I have to just run + to + and then - to - on the rear batteries right?Do I need a fuse when connecting the + to the other + on the rear batteries?I have a 220amp power bastards alternator so im thinking between that and a 3rd battery…

I have an 08 Jeep patriot that will most likely be seeing a Hybrid Audio Legatia L8/L1 pro combo up front and a single sub in the rear. I have been weighing my options and I am curious. I am going for a stealth install, so basically you will see the amp. I'll be using the factory 6 cd head-unit so my options are this amp, an h701/rux-c701 combo or a rockford fosgate 360.2. The sub section will be one 8" sub seeing 360 watts at 4 ohms. Which option would you go with if your goal was awesome sq from a stealth install using factory head-unit, factory mounting locations etc...

Are the zapco SP7-SL and arc audio PEQ 1/2 din mountable, as in can I mount them under my denon HU in my 1 1/2 din dash? If so, how would I go bout doing this? Just take out the pocket and slide in the eq?

Hey guys, I've received good information in my other topic so I thought I'd come back for some more. Got some questions to do with the setting on my sub amp and head unit Currently I'm running a infinity reference 611a amp powering 2 infinity 1050w subs but I'm looking to move up to a single 15". my head unit is a pioneer deh-p80mp and I play all my music off my multi-media player via aux input but the devices output is really quiet so with the way my setup currently is, the maximum I put my head unit to is 55 out of 60. I thought that head units have a point at which they clip but I can't hear any distortion. So I don't know if this is a problem or not. The way the sub a…

Well today my 5th generation ipod video decided it was going to take a chit. something involving the drive broke off and they want $150 to fix it. I have virtually no cds anymore so this is a very bad thing. I have a 16gb flash drive, and am looking for a Head Unit that has a usb connection so I can try to use this for music. I have never owned one with a usb connection, and am trying to find a quality yet inexpensive H/U that will serve this purpose. Also wondering if JVC makes any H/U's worth buying that do this?
