Ohm's???
 

I'm looking into buying some Kicker Comp series and which is most gernerally better 2 ohm 4 ohm or 8 ohm. I have a pionner premier series deck 50x4 a old school orion 275 sx 150 watt bridged at 300 watts and a alamani capcitor. Not really sure if that will help all yal but I heard more ohms=more bass but all the competion guys are running 1 ohm.

Here check this out u most likely want 4 ohm DVC.

ohms are the resistin's ?? not sure about spelling. you can wire them in series or paralle an get different ratings.. what you have to do is make sure your amp can handle the rating.. like dont run your speakers at 1 ohm if your amp can only handle 4 usually high end amps an speakers are running 1 ohm..

alright I i don't know what ohm my amp is I got it from my dad its a old school orion 275 sx 150 watt and bridged to 300 watt

ohm's = resistance, it aint hard to figure out how to calculate that, it just depends on what kind of power your looking for.

what do you have right now?

Rockford Fosgate® - Woofer WiringWizard check this for wiring.

just my 2 cents: (in addition to the other posts) different ohm speakers run at different temps also... This is what i'm told anyways... :w2:

alright thank you guys the rockford post helped the most with cause the pics lol

To understand ohms you need Ohm's law:

R= U /I

you also need the Power law:

P= U x I

To gain watts- which is what you want,you need voltage as current.

Some amps are built to deliver huge voltages other are better in current.

Your old school orion is a competition amp. Built to cheat! That means it can deliver lot's of amps due to it's heavy power supply.
It can feed low resistance at the speaker output. Normal amps aren't able to do that without getting to hot and destroyed.

Now it gets interesting!
The less resistance the speaker has, the more amps are needed to drive that speaker.
remember: If resistance goes up, current goes down and if resistance goes down, current goes up!
Only a really good amp can handle that low resistance. That's why most automotive speakers have the 4 ohm resistance.
To make it more difficult restistance changes with frequency. So the 4ohms are just an average.
There are subs available going close down to zero- what is close to known as a short.
Which destroys cheap amps!.

Those orion amps where known for their ability to deliver lots of amps and to drive speakers in the low resistance area around 1 Ohm.
That means if you put four 4Ohm speaker parallel, the orion can drive the resulting 1Ohm load without problems.

To calculate the resulting load you need two calculations:

1) speakers in line:

resistance adds up: Rres= R1+ R2+R3+...

2) speakers parallel:

resistance gets always smaller as the smallest resistance

1/Rres = 1/R1+ 1/R2+ 1/R3+ 1/R...


You see a bit of math is included. You can also combine both laws.

A simple example: You have two 4 ohm speakers.
In line they add up to 8ohms
parallel, they get smaller to 2 ohms.

So which circuit would you choose for your orion?
Right, the second one due to it's high current ability to drive low resistance.

I hope, thats not to confusing.:c:

One last thing: your Orion can deliver 2x 75 watts at 4 Ohm. That doesn't sound much at all.
BUT:
At lower resistance it can deliver twice the power! That's how they are built to cheat. You can compete in lower wattage classes. They will deliver more power with lower resistance!

If you are not completely satiesfied with your Orion, I will pay the shipping and make sure they are properly disposed and recyceled:tttt:

who uses U cmon now lol

E (electromotive force also knows as V)
I (stand for current or amperage)
R (Resistance)
P (power or watts)

E = IR or R = E/I or I = E/R

and for Power there is

P = IE or P = (E^2)/R or P = (I^2)R

but like stinker said its pretty simple, if your good a math i can explain more laer i have class :td:

What the..... I damn near deleted that as spam:s: lol

:lol:
guess, it is the damn euro thing inside me...

Damn, when I would get my hands on an orion amp today- real good old skool
not those skinny, flimsy ones.

:lol88:

i kinda forget hot to set up an am with just using a DMM though :humm:

You need:
a) Test tone cd (shoot me a pm if you need it)
b) DMM with AC Voltage setting
c) formula: voltage= SQRT (P x R)

- use a 50Hz or 60 Hz tone ( DMM must be calibrated to this)
- max RMS PWR of the amp multiplied with the speakers resistor and take the root of the result. The result is the max. voltage at peak power.

turn up gain until you reach peak voltage as calculated.
Or a bit lower to have a safety margin.

you are done.:c:

so is P is E^2/R

and then you have E^2/R times R

which then makes E^2

and the SQRT of that is E

and your measuring AC in volts

so E=E :s:

hehe that was fun.

anyhoo for the other guys who arent crazy at math

if you have 300 watts of power (RMS) at 2 ohms comming from your amp and your subs are wired up at 2ohms resistance

then V = SQRT(300watts X 2 ohms)

so you get V= SQRT ( 600)

so your voltage should be 24.5V :tu:

you confused me badly...
:dang:


next time I choose the formula for AC, not DC and then we go wild with complex Z, j and i

ooh so we get to talk about magna flux and impedance now do we?:pca1:

no we don't- we keep it simple!:w2:
But maybe we can collect some simple rules and laws, like wiring diameter compared to wattage, how to wire speakers, where to install the wires to avoid hissing and noise.
How to install CB's without trouble and noise.
Dual battery installs in the correct way without those ridiculous relays.
Some tricks what can be done with relays, diodes and switches.

It would be a help for neebies and everyone to have something like that sticky.
What do you think? There is no need to go to stereo sites- we can do it ourself adjusted to trucks.

How can I find out that Im pushing my full power out of my amp to my kickers? Is there a way you can read the rms or anyhting with a volt meter?

Yepp, there is a way!
1: track down your speakers resistance
2: track down your amplifiers rms power. Please no music power or peak music power output these are unreal wattages.
3: use a single 80hz tone for subwoofers and 1000hz for speakers.
4: connect your DMM in a AC voltage setting to the amp speaker output.

5: use this formula: V=SQRT (rms wattage x resistance)
example: V = SQRT( 25W x 4 Ohms)
the multimeter readout should be V= 10V.
You don't need a load at the amp -just the DMM and the test tone.
You don't have the test tone- shoot me a pm.

warning: Set all amp and headunit adjusters like bass boost and equalizers to a zero level to get a real world signal.
:hellox:

the lazy way is to post your amp rms and speaker resistance...

or do you want a visual warning like flashing Led when reaching peak volume?
its possible to do that.

My orion has a led peak power on the side where my gain is and where I can switch from mono to lq(what excatly does lq mean lol:argh:

and one thing i forgot how do I find the ohm's. I want to takes those four ohm kicker competion series to the full potetionol with my amp you think it will handle it even with the capcitor?

What do you mean by this lol. Sorry just didnt make since. Are u wanting me to turn all of my bass boosters and equaliers off and turn the gain up for they hit harder or what?

No problem:
so your kicker speakers have 4 ohms? A single one or more of them?
How are you going to connect them? parallel for maximum output for your Orion amp?

- Yes, turn off all boosters and equalizers. an equalizer boosts your signal very heavy
+3db equals to double volume- so that you reach the limit very quickly.

- Iq does mean that:
Incorporated in the high-pass crossover, Intelli-Q maximizes the
performance of a subwoofer. The high-pass subsonic filter removes
unwanted bass output from the woofer, increasing the output of a
subwoofer by as much as 3 dB due to the increased mechanical power
handling. Depending on the enclosure, using Intelli-Q can increase the
low frequency response by an additional 10dB! The type of enclosure
used and the woofer’s excursion capability determine acceptable
boost levels.

That means it cuts off very low unneccessary subsonic frequencies to be able to have more cone movement without destroying the speaker cone.

That makes alot of since. I have set up some systems but I want this one to be advanced. And yes I have two kickers and I'm going to be setting them parrell. I have a few more questions a guy who used to work for us was kinda a B/S'er and I have a hard time believing him because he said 8 ohms will hit harder but thats how this discussion came upon. But he said that if you havs 800 watt subs and only a 600 watt amp you can have everything up and the subs won't ever blow. To me that sounds ridiculous even though every sub has a peak power. So what do you think bud is it true cause I dont think it is. And I have a pioneer premerrie series deck two pioneer 6x9's, two pionner 6 inch door speakers my Orion amp, Alamani capcitor and monster cable wire and two Kicker comp. series subs how do you think my system will sound will I blow alot of people out of the water, even with the subs at 1 Ohm???

You will have a blast if everything is set up right. Use your speakers in parallel! Because your Orion amp is built for high current in a parallel application!

Each speaker will get the same amount of current in parallel.
That means you double the volume by supplying more current.
Don't be afraid- Orion amps are built for that!

A series application will increase resistance and cut the supplied current into half.
That means: less power for every speaker!

8 ohms series on a Orion amp are a waste of power.

You will get a great sound with 2 Ohms in parallel.

everything will be set up right. Have you seen the pics of my box that I custom made so I know all of it will be bad ass I just need to out thump my bro with his Dual 12's and a kenwood 1000 watt amp. And a few other of my buddies:humm: But they will bring it on adn so will I. What size ports should I run for the kickers I have two inch and 4 inch

It depends on the kickers itself.
Go to the kicker site and get the number supplied with them. They will also tell you if your speakers are for a closed or ported application.

You have to built your box according to those specs to get a maximum of punch.
This is neglected very often and one of the causes why people aren't satisfied with their speakers. But it all depends on the built!
Go for solid MDF- no OBD boards...

Don't fear Kenwood- you got an Orion, man!

The bigger port causes less venting air noise.
Almost all application that are sold now have bigger ports. But it depends on that what Kicker recommends!

Alright I'm ready and thank's for all the help buddy time to show how we cowboys roll:rocking:
