So I have a 80 amp fuse inline from battery 14 inchs away. Was expecting this fuse to blow. I am running a sundown 2500 @.5 ohm to a xcon 18. Question is why has it not blow I'm I not getting the watts I think I am? Voltage out of amp to sub is 50 volts.

ok i just got a alpine cda9855, and the preouts say 4 volts. i am going to be using a us amps ax1000de and a us amps merlin md41, and the input gain on the ax1000de is 150mV to 3 volts. and the md41 i dont have the manual on. so my question is. will a 4 volt preout work with this amp, and if anybody knows if it will work with the merlin as well. also what exactly will the difference be between 2 volt preouts and 4 volt preouts. becuase im pretty sure 4 volt is better. thanks

I think that I might run into some electrical problems in my new system that I'm currently putting together. I want to try and avoid it if I can to save money. I drive a 2000 Jetta VR6, it has a 120a stock alternator and this is my current battery My head unit is a Kenwood KDC-248u 4- Memphis PR 6.5's components in the doors My amp is an AQ1200d and this is where my first question comes in. I am looking at either getting 1 12 Icon, 1 15 Icon, or 1 12 Xcon. My question is should I play it safe and run them at 2ohms using ~870 watts or 1ohm using ~1200 watts. How much of a difference will there be in the sound and will it even avoid any electrical problems. My next questio…

I have a nendo BC2K that got a small amount of water in it,popped 2 transistors/mosfets.I'm having a hard time cross referencing the fets.I dont know if I have the P channel or the N channel fets,digikey pulls all sorts up.part number is IRF 3205.I'm grateful for any help.

i've got a crossfire vr2000d thats supposedly been modded to be .5 ohm stable and handle high voltage. it has 2 hookups each for power, remote, and ground. these all need to be hooked up right? how can i test the amp beforehand to see if i can run it daily at 1 ohm? it should do around 2800x1 @ 1 ohm, and i'll be using 1800-2kw of that for my 12's, so it wont be running full tilt but about 2/3. anything else i need to know before firing up this beast?

I dislike the dimming of my lights and i never want to it happen again. Right now i have 3 Fi SSD's with a RF t1000.1BD and a T500.1BD powering them. I have a 200Amp Alt and one optima yellow top. I haven't installed the equipment yet, so i don't know if it will dim. I have 2 electrical fans that drop my volt gauge from 14.5 to 13.5 and when i have my lights on theres no volt drop at all. Considering the fans draw 20-30 amps each, that isn't that bad. I have the Big 3 upgraded with 0/1 awg. Grounds from my frame to battery, body to battery, block to frame, and frame to cab. I have damn grounds everywhere The real question is, i want to be able to run my fans, lights, ster…

looking for people with recent experience with them, I am interested in the APA2160, fiarly sweet amp from their CES show car, but I am wondering why their prices are so low in many places??

Alright I just want to clear this up so I don't fry an amp. Here is how I will have my set up wired. What do I disconnect just the front battery negative? Or what? And do I take out all the fuses then plug in the postive to the amp and THEN negative ? I just want to make sure

As the title says this will be about the older fosgate 1000.1bd. Im not sure i understand the class"BD" thing? how does that compare to a regular just class D amp? Also im going to have to double check but im almost positive the SSF on the amp at its lowest setting is only 50hz, can that hurt me at all as far as sub performance? i have a box tuned in the 33hz area. just looking for any kind of technical answer to help understand this amp better and decide if it needs to be put up in the garage and replaced lol.

ive got two amps in mind does any one have thoughts on witch would i be happier with the saz2000d or the aq2200d the one that i get will run one 12" fi btl w/cooling in a 2.5ft3 tuned to 33hz big three and 200amp alternator just wondering witch to go with

So my amp has been acting up since the day I got it.(Diablo Audio Technologies HellFire 1000.1) The problem is that it plays for a few minutes after I turn on the truck and goes into "Alarm Mode". (If I restart the truck it will come back on for a few minutes as if it had a clock inside telling the amp to only turn on for a few minutes(3 or 5 min.)) At first the ground was a little loose so I tightened it. It still kept on doing it so I bought some Sandpaper to make a nice, clean ground and it still does it. Can someone help me? P.S.- As I've mentioned before I did a direct swap with my MTX amp. In fact, the only thing I changed was the ground which is alot better now. H…

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.

Hi Guys, A friend of mine needs to finish the big3 in his car. He's wondering how to put the wire between alt to batt. From stock, there is a wire coming from the + of the alternator, going to the starter(démareur in French !) And this same wire goes to the + batt after the starter. So, the question is : can we just put a wire between the alt and the batt without hooking it to the starter ? Or do we have to follow the stock wiring ? Waiting for you, all the experts, please!!!

ok, since fords are a bit**, and the ground and power wire are connected behind the engine, and i would never be able to get them off and back on without taking alot of stuff off, maybe even the engine, can i just cut the original wires, close to where it is connected and just add my new wire to it. Because most people say that if you do the same with an amp it wont make a diffrence, so would it work. nv about clip.

Hey all, I'm going to buy myself a new headunit my budget is around 250$. So far the ones that catch my eye are the Pioneer premier DEH-p600ub and the Ecipse CD3200. I don't know much about head-units...the pioneer caught my eye because it has a 7 band equalizer while the eclipse only has 3 band. The eclipse caught my eye because it has 5 volt pre-out compared to the pioneers' 4 volt (apparently more volts is better). Visually I like the Eclipse better cause people in Montreal don't seem to have them and looks more classy compared to pioneers blue leds all over the place. I'm hoping someone who knows about hu's can help me out, please help! These are the ebay auctions i w…

I am gonna be running 2 sets of kicker ks 6.5 component sets,i believe they are 100 watts rms.i am looking for a decent amp to run them,my budget is up to about 200$.any suggestions?

Iv read many a thread talking about caps and well, nobody likes them ^^. So what i was thinking about doing, instead of just chucking it, would it be possible to remove the LED display and wire it upfront to be used as a voltmeter? Opinions?

Hey guys i need some help looking for a head unit for my car. Budget: around $160 so used is a option to maximize my bang for buck. Goals: Nice Stereo Remote Sub out Control in the future might want to amp the front stage CD,mp3, and usb thanks guys!

Soo i was drivin down the street bumpin and all the sudden my subs cut off, when i checked it the amp was not turned on but the fuse wasnt blown, i took the fuse out then put it back in, the amp turned back on immedatley after. next time im driving it does the same thing and i have to take the fuse out and put it back in to turn on the amp. it only cuts out when i turn it up to a little over half volume. i would just go throw on another fuse but they dont sell any 250a fuses at my local places so id have to order online

So I installed my 4 AA Carbon fibers and my SAX-100.4 just now and when i turn my truck off a "POP" comes from the speakers, i only turned my truck off twice so i only heard it twice and i think its coming from 2 speakers. How do i get it to stop thanks guys.

here is the situation, i was going to install my new alternator, when i took the belt off the old alt, i noticed something, even though i had all the tensioner down, it didnt come out easily, wasnt a really hard task, but was unusual then, when i installed everything, i was going to put on the belt, but couldnt put it in place, it needed just a bit more to enter, and a friend suggested me to put a longer belt what are your opinions, but would need them fast, need to do it before going to school tomarrow

Hi guys I've been looking around at some mids and highs. I'm thinking about trying to run 2 6.5s an 2 tweeters in each front door of a 03 ford explorer and maybe some coaxials in the rears. My question is what kind of amp should I run a 2 channel or a 4 channel? It's seems the 2 channels are usually quite a bit cheaper. What are advantages of running a 4 channel?

A buddy of mine just got a new 2010 Silverado. He took the old head-unit out of his other truck to put in this truck. The HU is a pioneer in-dash double din, not sure which model but it's fairly new. His harness for the old truck (an older silverado 00-05) is not the same for this new truck. We've looked everywhere for a compatible harness but cannot find one. The stereo also doesn't fit where stock double din was, so I guess we will need a dash kit too. Any help would be VERY appreciated. These new vehicles piss me off.. Here is the stock stereo

Hey guys, i just bought a Aura Force 400q amplifer. I don't know all to much about it. they seem like nice amps. I know its older. Its a 4 channel. Can anybody tell me anything about it?? Some general info would be good, Is it a good brand/qualilty? or just some opinions.. thanks.. BTW its almost mint, and I got it for $50.

Someone told me that one of the usamps line of amplifiers lie about there actual wattage they are putting out. is this true, if so which series of there amplifier is this?
