if im wrong feel free to help in anyway. i assume i would need to upgrade my alternator, just a givin. then add about 3-4 batteries that output that voltage while using a device that seperates the batteries in the back from the one under the hood, but also charges the batteries in the rear. of course whole car can not be ran anything more than 14 volts on a 12 volt system(14.4 was the most i seen but i could be wrong) so the battery under the hood would be different than the one's in the rear. and could anyone fill me in about the missing link module, i know its not good to charge the batteries on 15.4 volts but i think it has a button to switch between from 15.4 to 14.4,…

specificly the a3000db, here, and the a520-2hp, here...... what can anyone tell me about them? how are their amps in general? the reason i am asking is becuz a install i am about to start might include these two amps, if they are atleast capable of their rated power and good performers... also, if u can list amps in the same power range, the mono amp needs to be either 1/2 ohm or 2 ohm stable(the subs are dvc 2ohm) for around the same price...plz list....i need them to be a "matching" pair thanks all wheeeeeeeeeeeeeeeeeeeeeeeeeee

Ok so Im kinda stepping up a little bit on the whole sub scene and I kinda got over my head a little bit. I thought I would look to you guys for some guidance. I have bought 2 15" Orion HCCA's. I bought the dual 4 ohm version thinking Id just run 1 big amp. Well my noobness has bit me in the ass. I need a large amp as wasnt really thinking of the amp draw that this would present. So if I can get any suggestions on amp/batteries/alt that I may need I would owe a favor for sure. I know you guys get these questions all the time and I didnt want to be "this" guy but I really have no other choice. I want to learn this instead of just paying some shop to do it for me. …

Ever sinced I changed my stock battery to a XS D1200, after a few days of the initial installation, been noticing the car is starting to take a hair longer to start... While working on the car today, i noticed right after i got done driving it.. it was reading 12.6v.. that's pretty low from just turning the car off. So i clamped the battery cable, reading 0.4A draw... hmmm... Pulling fuses under the hood and came up with this- AM2 fuse - (according to forums, controls Starter, fuel injectors, etc....) this fuse is pulling 0.15A DCC fuse - I do not know what this is but it is said dealers pull this fuse to prevent battery discharge if car is left unnattended for days. Thi…

I know theirs many of these posts about people asking for a good amp to run there sub but I thought id post my own topic to fit my standards...I have/on the way a 15" Fi SSD. Even though I still haven't received my subwoofer and haven't heard it on my current amp I still don't think my US AMPS XT2000D is going to feed it the power i want. with that being said I want some ideas on a good amp that can put out as much power or a good recommended amount of power to push the SSD. my price range would have to be around 200$ or so...idk just thought id get some ideas if i were to get one soon.

It's an Atomic 3000.1 2 FI BLs @2ohms 1200 XS power battery in the rear 2 runs of 0 gauge wiring stock alternator/front battery Has been playing fine the past week or so, but as of yesterday, any time the volume gets turned up around halfway, nothing ridiculously maxed out, the subs make a funny noise and the amp goes into protection mode. I've already checked that the ground is good, no loose wires or anything touching metal, the usual routine checks.. Not sure if it is getting starved for power or what's wrong at all. I'm not 100% audio savey but I know bits and pieces here and there. The amp is an older model that was damaged when I bought it, but I sent it back to…

okay i have 2 mtx ta81001 amps straped....@ 4ohms it does 2000 rms .... because i have a D2 btl that is the only safe way i can run it..... my friend has an orion 2500d the silver one with the endcaps..... should i sell my amps and get his...i have meterd with my current setup and did 140.4 on the tl there is a comp this weekend and they are gonna use an ac mic... now i was planing on dropping the sub to one ohm for the burp....but i know that its not safe as those amps arent half ohm stable....should i get his amp? plus an advantage to having his is less headache dealing with one amp...... here are the specs im looking @ 2500d 2500rms @1ohm 81001 1500rms@1ohm x2 = not s…

nevermind..hehe what if i can't reach the engine block ground? will that be alright? wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

I think I might go full active, and I would LOVE to go the route of a 6ch amp. I was looking at the Audison VRx6 Direct, damn its expensive. I know PPI had a nice PC6600.2 back in the day before the DEI switch over. SoundStream had the Davinci (overkill for me, I dont need 7channels) Anyone have any other suggestions?

anyone here heard of nvx? how do their amps rank up against the rest? interested to hear your opinions and experiences.

I really hope somebody out there can help me. I have a Fusion amp(FP-1000) I also have a remote bass control for the amp. Which is a little box that goes up front with you, giving you the feature to be able to control the gain on the amp. It is connected to the amp by a telephone like plug and cord. Here is the picture of it. http://www.fusioncaraudio.com/products.php...p;product_id=97 I am not sure if they let you post links on here, sorry if you can't see or read the link. I went back to the shop that installed the audio setup in my car. He feels really bad for the bass control that I have now stopped working. He contacted Fusion to get me a new one which fusion says t…

how can you test if a bad remote line out from head unit is causing amp not to on?

Can any one post a tutorial( or show where one is) on how to set up the gains using a oscilloscope ???? ! would like to set up my stereo that way if i could figure it out.

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

So i have an Fi Car Audio SSD 12 inch Subwoofer and a planet audio amp and the box is a groundshaker sqpxl 1 12 at 33 -35hz and how do you guys think i should tune my amp to this setup

Hi, I will be doing 2 15" Icon build on a crescendo BC2000D etc in a Dakota crew cab and have two nice decks in my possession. a Kenwood KDC-bt945u and a Clarion VZ401 DVD deck. Ive done a lot of researching on pre-out voltage but have seen so many opinions to as if it really does make a huge difference or not. Basically the Kenwood has 4v preouts and the Clarion has 2v. I like both decks but would love to have the dvd screen but not at a major loss of output or sound quality. My question is, will I notice a difference or should I go with the Clarion? Thanks,

I'm looking at this dual headunit and I was wondering if it is a good choice, its only 17RMS but I dont really care I just want to make sure it won't blow up I plan to get a amp for my speakers soon so 17RMS is fine right now. I already have a after market head unit in my car will I need the wire and harness still??? this is what I'm looking at: http://cgi.ebay.com/DUAL-XDM7610-CD-MP3-AM...1QQcmdZViewItem

I was wondering if anyone knows what type of RCA's would work best for a Soundquebed 3500 amp? I was hearing about differential and coaxial type's is why. I know one type is twisted and the other is straight. Also,any brand inpatucliar would help.

Well... I reciently bought a Pioneer DEH-P940MP. I was planning to run the front speakers acvive and the rears passive. However, I didnt see in the manual that you can do this. I NEED rear fill, burbs are huge inside, components up front arent going to be able to be heard way in the back. I do carry passengers. I had 2 ideas on how to accomplish this. Run a LOC off the H/U's rear speaker outputs to the amp for the back speakers. Thats if the signal is not seperate (trebel/midrange). I dont know if the internal amp even works in this mode. It cant be shut off so its definetly on. Or... Get 4 Y splitters. Use the output RCA's on the amp and " blend" the treble and mid range…

Can using a bass knob cause damage? If so, to what extent. Should I go ahead & set my gains to what my bass knob would normally be? And finally, what exactly does the bass knob effect? Does it stay within the preset gains? I like being able to turn it down with just that little knob, or turn it up when I want to blare it. I was thinking of setting it all the way up, then the gain to where it gets the right AC Voltage, would it be fine?

Doesn anyone have any expeience with these amps? I am currently shopping around for new amps for the possibly near future and was reading a little bit about treo. I know their subs are of good quality but what about their amps?

I have a Hyundai XG-300 (ya i know they are not that common) and I'm looking to do the big 3 upgrade with 1/0awg but before i do i want get get a new alternator rather than the stock one that i have(120 amps) Only problem is that i cant find an alternator made for my car that does any thing over stock and i need at least another 80 amps at the minimum..basically im trying to power a btl 15 or grab a re audio xxx 15..pretty much i need to get 2000w + rms out of my charging system.(i am aware of the extra batteries needed)... my question is would any H.O. alt. i find work fine with my car or should i just buy a new stock alt. and get it rewound and altered to put out more p…

HOLY chit BALLS I can't wait till my amps get here... I'm just f-in happy, I got lots of amplifiers on the way!!! WOOOOOOTTTTT....can't wait! -Kicker KX 450.2 (225rms x 2 @2ohms for XXX mids) -Kicker KX 200.2 (~30-40 rms x 2 @6ohms for Vifa Tweets) - TWO Powerbass XA3000d's ;) (One daily, two for comps ) -One 15" RE MT anticipation sucks...

Hey guys my brother drives a 1996 Jetta GLS. The other day his car quit playing music. I know its not the head unit because I took it out and tested it and it works I even put in his older pioneer that also works and it played for about 1 second then it stopped playing music (same happened with the first head unit also). My question is what could be the problem cuz I have no clue. Any help would be appreciated

My jvc kw nx 7000 is buggin' out and they want $50 plus shipping for me to send it to Colorado to diagnose it before they can even give me an idea on price. Has anybody ever dealt with a company for touch screen repair? I am reluctant to spend 70-100 just to send it out to be told it is another 400 to fix. Any ideas?
