  5. Need help with system choices...

    Lol i guess i dont really need to know how to do all that.. Thanks man :D it was good learning that right there. I will still prolly see if i can wrap my head around that and use the clamp meter and all. Thanks for the help I feel better about running this amp to this sub now. I'm not too worried about blowing it. I have seriously overpowered subs for a few years now so im used to doing that. I'm smart with how i play them and how long i romp on them for. But this will just help with knowing more about where im actually at on power. thanks again man

    Ok im understanding that much. I'm taking down my little notes off this haha. I love math btw i just don't know the equations thats it. once i see what goes where it looks like #s to me lol. So my real question after this is lets say on your amp then you do set it to that. 60 volts coming out when your doing the gain setting again. Lets say running the system on the 40hz tone like you did you set your amp to 60 volts now does that mean your only gonna see that 900watts??? and if so then why in the world would i want a 5-7krms amp lol :D i know i gotta be mixed up on something there..

    Ok well not to ask you to straight up teach me everything here but this is making very good sense to me. If i have box rise of lets say 5ohms as you used. How could I set the gains with the dmm... I mean even if i found out the rise of the box with a clamp meter and all how could i set the gain closer to where i want it at 3k rms with the dmm... Sorry if this is annoying you but im learning a great deal here :D thank you sir :drinks:

    Here's the thing that a lot of people don't understand about gains. If your amp will do 5000 watts @ 1 ohm, wiring at 1 ohm does NOT mean you're going to get that 5000. After voltage drop, box rise, etc you are not going to see that power.

    Now you can get MORE than 5000 watts @ 1 ohm, but the power will be dirty and it will be a clipped signal. You can also get LESS than 5000 watts @ 1 ohm. This is the reason why you have things like the volume knob, the sub level on the deck, and the gain knob on your amp.

    Here's my opinion. Wire the amp @ 1 ohm. Then, if you're set on using a DMM to set the gains, set it at something lower like 2000 or 3000. Truth be told, even if you set your amp with a DMM to put out 3000 watts, you won't be seeing that much power because you aren't accounting for box rise.

    I'll use my car as an example. I have an SAZ-4500 wired @ 1 ohm. If I were to use a DMM to set my gains, I would set my amp to put out 67 volts to see 4500 watts @ 1 ohm. After box rise, I'm @ 3.67 ohms clamping 2600 watts at roughly 98 volts and 26.7 amps. If I would have tried to set my gains with a DMM to 67 volts, I would only be seeing 1200 watts out of my amp because after rise I'm actually at 3.67 ohms not 1 ohm.

    This is very very helpful man. Now my question is why would I use a dmm then if i couldnt account for the box rise... But besides that what your really saying is if i set my amp at likes say 55ish volts which by guess would be something like 3500-4k i would be pretty safe, because i would be seeing much less than that anyway. Then maybe after its broken in and i can find someone with an o-scope i can set it proper and account for everything?

    Well all i have to set my gains with is a DMM.. I know i can match everything with the formula that i found offline somewhere... I had my old system set like that and it sounded great. But I feel I will NEED an O-scope for this one. My prob is i live in MO so i don't know anyone around here that has an O-scope lol. I mean i can do it by ear so i know it doesn't get overpowered via bottom out or anything like that.. but yea lol....

    I have a DC xl 15'' d2 sub that is BNIB.. I have not gotten to play this badass sub and i wish i could do it. My problem is i have an addictive audio 500.1 amp... Now if i do hook this sub up at this point the only thing i can safely do is run it @ 4 ohms... I have the electrical to back it all up, I just don't really know what to do. Should i sell this badass sub and get a lvl 5.. Should i try something crazy and put the full amp to this sub... Should i get rid of the amp and go smaller??? IDk lol I'm mad i got into this situation.. but the price was right lol. I will have the box tuned @ 32hz with whatever setup i get. And only have about 3.5-4cubes to play with. What to do...

    I need an alternator for my 2007 Scion tc. I have a limit of $400 on it. I am going to be powering 5k and a sundown 100.4 with it. I have a D3400 under the hood and 2 Decka group 31a's in the back. 2 runs of 0guage will be used and the big 3 of course. Well PM me with offers im really looking into DC Power and Mechman the most. Not opposed to anything though.
