newb question about amps
Thursday, May 11, 2006 5:22 PM
ok I recently pick up two 400wt kickers a piece what kind of amp do I need to run them I know I need at least an 800 watt amp but I get really confused when amps say 200watts x 400watt bridged. Can someone help me out I'm new to the wonderful wonder of subs

what kind of amp would I need to run the subs?

Model #'s of the subs please.

Model #'s don't have anything to do with what amp he needs. What we need to know is the number of voice coils and the impedence of them. Either 4 ohms or 2 ohms.

The only Kicker subs that i know of that are 400 watts are the Kicker CVRs, they should be a dual 4 ohm voice coil . What you will need is a nice mono amp putting out 600 to 800 watts RMS. The subs would be running at 2 ohms at the amp if wired correctly.

As for understanding the power ratings, Ohms Law and all of the good stuff that come with it, that may take another day...

Yes, they do.

Which you can get from the model number.

so let me get this straight... YOU can take 2 dual voice coil 4 ohm subs...and wire them together to get a 2 ohm load on a mono amp? i want your super powers... and on this note.... stop giving advice in this forum or learn before you speak


On the other hand....you have other fingers.

haha first of all, how do we find all that info?? WITH THE MODEL NUMBER!!

And sedcond of all, id like to see you wire that setup down to 4ohms, properly. If you can, you are god.

i ment to say 2 ohms... So flame on somewhere else...

Not to mention not all model #s give you that information...

First off, how many subs are there, one or two? Second, is the amp 2 ohm stable or 4 ohm stable, or 3 ohm or .5 ohm stable? There is little information here.

basically, to answer the initial question:

You have 2 outputs, each 200watts. Bridging an amp is another way of connecting those 2 outputs to one output. SOOOOOOOO you would connect ONE positive and ONE negative instead of both. The diagram should be on amp itself on which ones to connect together.

If wired properly, using series and parallel, you can get almost any resistance you need for almost every amp. Post some specifics and I'll be glad to help you out.

NO YOU CAN NOT! MY FUKKING WORD IM SICK OF SEEING PEOPLE SO SURE OF THEMSELVES GIVING MISINFORMATION.... YOU CAN NOT WIRE A DUAL 4OHM SUB TO 4 OHMS, YOU CAN NOT WIRE 2 DUAL 4 OHM SUBS TO 2 OHMS, IT IS NOT POSSIBLE, CUT AND DRY, NO WAY AROUND IT, EVERYONE THINKING THEY KNOW SHlT AND TELL LIES, STFU AND LET SOMEONE GIVE ADVICE THAT KNOWS WHAT THEYRE SAYING!

Re: newb question about amps

if you run a posative from the amp, to a posative on one voive coil, then a wire from the negative on voice coil one to the posative on voice coil two, then the negative from VC 2 to the amp, it will show 4 ohms. Do that too both the subs too the amp, and the amp will see a 4 ohm load. Its just wiring seris and parallell together



heres what crutchfield (leader in audio equipment) says

2 dual 4 ohm subs can make a 4 ohm load on a mono amp... yes....now what you can NOT do, and what i have been saying all along is you cant do that and get a 2 ohm load...you have proven nothing

He's right, theres a reason it's called ohms law. Laws of physics cannot be changed. They are constants, not variables. you can wire a number of different combinations with DVC subs, but they will always be the same, more voice coils only means more options.

As for the original question, go with a mono amp. if the subs are dual 4 ohms, get a 1 ohm stable amp for the most power (unless they're one of those modulated ones that put out the rated power at all impedances). Do not go with the peak wattage. at best buy, wal mart, etc. it'll say "1200 watts max" or peak or whatever, that is simply the max power an amp can put out for say a 1 millisecond burp. Always look for RMS ratings on amps. For example, on sony Xplod subs, it'll say 1300 watts peak, but actually the RMS rating is only 380 watts. They will say "380 watts continuous" or "380 watts RMS" or something similar. If you cannot find the RMS rating on the box, dont even consider it. most companies I find that do that, usually go "haha! we got this guy to buy an amp that only actually puts out 50 watts RMS" Usually for lower quality stuff, the RMS rating will be a much, much smaller text on the box, if at all.

Also, dont forget, some companies like to fake the RMS ratings too. This is where forums like this come in handy. Ask around to see which company is more reliable. I heard kicker is an awesome manufacturer for putting honest RMS ratings on their boxes.

well his question has been answered again and again in all our arguments, he should at least post and say "thanks, i got it figured out" lol

Re: newb question about amps

First off, I had no idea how many amps/channels and how many subs, WHICH WAS POSTED AS MORE INFORMATION. So before going off on someone who is MECP certified, think again.

If he wants to run a 4ohm load, he can. But he needs the correct equipment to do so, which I have no idea what the ohm load is because all I see is yelling.

So if someone actually posted more information instead of trying to be a know-it-all, we could get this resolved. I am soooo sick of kids coming on and thinking they are hot sh*t and have no idea. Did I ever say he could wire anything? NO!!! I said almost anything is possible.

And I wonder why we have arguements on here every f*ckin day.

And just to make this clear, you CAN wire 2 4ohm dual VC into 4ohms. Here is how:

The first sub should be wired in parallel, making a 2ohm load.
The second should be wired indendantly, making another 2ohm load.
The two should be connected in series, making a 4ohm load to the amp.

The end.

only way to get a custom impedance is using resistors I'd think, but not alot of people, if any, use resistors in an audio system.

WHY DOESNT EVERYONE LEARN TO FUKKING READ. TAKE YOUR MECP CERT AND SHOVE IT UP YOUR AS$ AND GO BACK TO AN ELEMENTARY LEVEL READING AND COMPREHENSION CLASS SAM. YOU JUST REPEATED WHAT I ALREADY SAID....YOU ARE THE SECOND ONE ON THIS THREAD TO REPEAT WHAT I SAID IN TRYING TO ARGUE WITH ME... AGAIN LIKE THE OTHER DOUCHE.....
