Crunch Gp3000d Pro. With Maxxlink Questions.

[ROBERT 04XBLZ]

does anyone know the dimensions on this amp? ive been searching and every site i look at doesnt say its dimensions. also im getting ready to order two of them with a maxxlink. what would the ohm loads be? like sundown amps 3000 strapped say 6000rms strapped at 2 ohm.

gunna make me run out and measure?

gah

gotta earn my place somehow- if dont help ANYONE then i might get bant

I believe that the amp is 19-20" long X 9-9.5" wide. I never got around to measuring mine but I think that those are the dimensions that I read in the manual when I got it. I would expect in the 5k-6k range on two of those amps strapped at 2 ohms if you can keep your box rise at a minimum, otherwise they won't make near that power and you'd be better off running an amp per sub or per pair of subs if your going with 4 or more.

2.5 H

let me know if you need anything else

well i have two btls d2. so i would have to wire it at 2ohm? this will be the first time i strap amps. if you or anyone can explain to me how it works?

well, you don't have to strap them, you could just run one amp to one sub and just wire it at 1 ohm. you are most likely to have less box rise. but thats what i would do and what i'm going to do for comps

wouldnt it be better if i was to strapp them and bring down the ohm load?

acually, i do beleve both would still pull the same current because it says 300a fuse needed, and if you strap them, you need to have 600a worth of fusing. but with an amp per sub, you should see less box rise.

can someone correctme if i'm work (NIGHTSHADE!!!)

Absolutely bills. You more than likely see less box rise if you were to run one amp per sub. I tested this in my case and this is what I got. I had a single Crunch GP3000D running at 1 ohm nominal. When I would play a burp and get my power readings I would calculate for impedence rise and would get a reactive load of 3.88 ohms and the power output was only at 1900 watts. Now I have 2 Sundown 1500d's and they are wired each at .5 ohms. So you see the option of wiring lower right off the start because instead of having my one amp at 1 ohm I can run each amp at .5 which will produce more power right away. Anyway back to the amps are at .5 ohms nominal and when they are burped and rise is calculated they are at 1.45 ohms each. Thus each amp is producing 2000 watts a piece rather than one amp producing 1900 watts by itself.

Now in your case this is how that would work and this is just an example and the real numbers may be different. Now let's say that you strap the amps at 2 ohms like you wanted to. You are going to get a bit more efficiency at a higher ohm load but you will still have the rise effecting the power output. So at 2 ohms nominal let's say when burped you see something like 5.4 ohms reactive. Usually impedence rise follows in doubles such as 1 ohm, 2 ohms, 4 ohms, 8 ohms... So 5.4 is being a bit generous but it's just an example. Now the amps are capable of 6K at 2 ohms strapped and that's without any rise at all. At 5.4 ohms you would probably make in the 3000 watt or so range give or take a few watts. Now you move on to running a single amp per sub with the gains matched and you have each amp at a 1 ohm nominal load. You play a burp and calculate rise and if it carries the same trend as before you will be close to 4 ohms on each amp. But as I stated before with my single GP3000 it made 1900 watts at 3.88 ohms so I would expect the same amount of power or a bit more if you have a decent electrical system to help them out. So right off the bat in power you've went up from 3K to 3800 watts increasing spl by just choosing to wire different.

I can't guarentee the amount of power you will make because I just made up numbers to give an example, but in my case and the case of several others by running a single amp per sub instead of strapping them has resulted in louder bass and higher spl scores. It's something for you to think about and you have the option of wiring it both ways and putting it on a spl meter and seeing which one is actually louder. Sorry about the book, but I had to try and explain it all.
