So, I'm currently in the process of setting my gains for my 4 channel amp and mono amp. I've been researching on how to properly set your gains using a digital multimeter, and it seems like every forum and website tells you a different way to do it. The SSA forum stood out to me and made the most sense about gain setting, but it still left me with a few questions. My first question is should i set my gains for the 4 channel amp first or the mono, or does it even matter? When i set my gains for the 4 channel amp i will be using a 0 dB 1000Hz test tone, but what i'm not sure of is what settings should i use for my head unit? A lot of people say to set everything to 0. I'm …

what are the benefits of using ur subwoofers on a external crossover? is there any difference from using a subsonic filter. running subs @ 35hz.

Looking to upgrade my head unit and I'm between Kenwood ddx376bt or Pioneer avh-501ex

Well I finaly got to mesuring my cars voltage, and to my suprise, my dmm read 14.23 and this is all stock electrical without the big three. I got the voltage Through some cheepo 8 gauge from my most recent system. I wanted to know if this sounds good for a 1kw system. Thaw alternator is 95 amps and the batery is a die hard. I want some opinions if you guys think I may be able to run a aq 1200d whithout any major electrical upgrades. And I am doing the big three in 1/0 cable.

As the title states im looking for a new digital multimeter for a few reasons. I was looking on amazon and i see they have them ranging anywhere from $5 all the way to $200. I dont really know the difference one would have over another but im willing to spend anywhere from $10-$25 as its just for a few purposes here and there. If anyone has any options on a good decent DMM feel free to post them here as it may also help people in the future to decide which ones to get. Thanks in advance

How do you measure the actual output of an amp in watts? I remember my friend Aubrey telling me how, but cant find the info again. Im trying to figure out what my 601S Rockford Fosgate Amp puts out. It says 600 rms, and 1800 peak, which is strange for the peak to be so much higher, but anyways I've also heard that RF underrates their amps substantially like Kicker does. So my question again is how do I measure the power an amp puts out?

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!!!

i want blue tooth/ipod/changeable backround pic, the ipod is most important and SQ. what i have is in sig. i have good stuff and want the best deck for SQ. they both have the options i want. i think the p980 has a better screen and i think the ipod on the x991 is better. no one around me has this on display so I'm buying blind. please help me

do you think the US AMPS xt4000d is a good amp for a fully loaded 1 ohm 18 FI bl?

I ordered 1 guage wire and it should be in soon. I have 8guage running to my 2channel now that was drilled through my firewall. Is there any other ways to get such a large wire through? Id rather not put that big of a hole in my vehicle. What are my options? As always all help is very much appreciated

I need an amp that puts out 40-80x2 for my mb quart components. My budget is around 100. I've seen some cheap clarion amps on ebay. Do you guys have any suggestions? What do you think about this memphis amp? Would be nice if i can extract 70x2 out of it. But it is refurbed... Any suggestions would help guys. Thanks! http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...me=STRK:MEWA:IT

what is everyones opinion on the kenwood kdc-x790?

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…

Well on my way to class i smelt something odd... thought it was the dump i was driving past. i pull in to CSN and i see smoke go by my face... so i turn around and my whole trunk is in smoke.... now aparently my ground was bad (pops said too much current). ran 2 amps into 1 ground, just tapped into one amp ground to get them both going (Ground was VERY HOT when the smoke appeared). So i went to Lowes and picked up some 1 gauge and it dont fit in my amp terminal. so i grabed some 2 gauge... FITS... yet the wire is VERY stiff and i cannot find any Ring Lug Connections for 2 gauge so i grabed some bolt connector things.... yet it does not give me a secure connection and i wi…

Ok, I'm looking to put a new H/U in. Here are my parameters: -nav built in bluetooth built in -ipod control -dvd -double din -5.8" or bigger screen -sub pre outs Right now, I'm leaning towards the Pioneer Premier f90bt. A friend of mine has one and I'm really impressed with it. I can find it for about $650 new and $475 refurb on Ebay(would you guys trust a refurb???) The only thing I don't like about the unit is the cd slot. Its petty, but I'm used to flipdowns where the slot is behind the face. I think it looks a little sleeker, plus you get an extra inch or so of screen. Opinions on this unit? Anybody have any suggestions for similar units, preferably around the same pr…

alright so i just received my xs power d3100 battery... now how am i supposed to connect 4 1/0 gauge wires to it ??? do they make special terminals that hold 4 1/0 gauge wires or do i have to make my own ??

So i recently got a pair of DC Audio Subs..1000rms/2000 max.... well i have been told that it since they are a pair of 2ohm subs that a mono amp will not push it to the amps max.. i am looking to spend at the most 350.. I would really apppriciate the help:)

This is how my boat is wired as of now. 2 ga. from the alt (pos) and the neg. (don't know where it is grounded but most likely the engine somehwere). These are connected to the starting battery. Then I have additional 2ga cables running in series to the aftermarket stereo battery (a deka intimidator), off of this is where my 4 ga. amp wires run (pos and neg in the same fashion). My question has to do with the grounding. I would guess that it would be better to ground my aftermarket battery directly to some big ass piece of metal (but alas only fiberglass around) and the same goes for my amps. It seems that all the ground is running all the way back to the starting batte…

ok im going to try to make this short and simple because ive been thru hell looking for a new HU that can beat my RAVDVD1 (its nice but lacking a lil and very slow) im lookign for a few features i need and a few i want and other then that i dont care what else it has... so far ive found some close canidates but nothing for sure yet (top is JVC and i dont want a jvc to be hoenst) Features i need: 5.1 support with 6 rca outs dvd video support single din sized Features i want: DVD audio support Ability to handle high SPL USB input DIVX (very very important but all in all i could do without if everythign else was right) 4v+ preouts with 2 360.2 processors and 12 channels of …

US Amps XT-1600.2 I was looking at that amp on here, and thinking about maybe getting it. It looks good to push my 7515. Or should I consider something else? I'm just begining to start shopping.

Okay, So here in a few days I am ordering some Mach5 MAW-15's and I was wondering what Amp would be best to push them...... I have a list of some amps that I "THINK" would work good with them. So tell me what u think. Feel free to inform me of any amps that arent on the list that would be good for the MAW's Kenwood KAC-9103 US Amps XT-2000D Kicker ZX1000.1 Crunch PZi 1000.1 Hifonics BXi 1606D Hifonics ZXi 1006 Kenwood KAC-9152D. ~MadroX

I've been going back and forth between buying amps and i cant decide which one i should go for. I'm looking at either getting a refurbished Rockford t30001bd or a refurbished Autotek mean machine 4000.1D. I cant choose between the two and i need to decide soon can anyone help me choose which one to buy.

I took my red top out an put in my yellow top( got it for 50 bucks). I thought maybe my red one was going bad. Buddy of mine put his meter on it. It showed 12.63v ( that was about 15 min after shut off). I took it out ( a day later) and measured again 12.63v. So, i wait one more day 12.63v . My buddy said that 12.63 was low for those ( should be around 13.3 according to him). what do you think? Is it going bad, should i wait a bit longer and see if it drops or just run it with the yellow top (parallel)? thanks

So I'm getting ready to do my wiring and I came across: http://www.remybattery.com/Departments/Cable--Accessories/Connectors--Lugs-and-Terminals/Compression-Connectors.aspx the battery terminals look pretty cool... Any thoughts on compression terminals? Pretty secure?
