2 ohm?

[slideking 10+ year member]

My brother just bought some 12 l7's and when they got here I saw that they were 2 ohm. What kind of amp is going to push these and why would you even buy 2 ohm subs. Will the 1200.1(kicker) be ok to use, or will he just be getting half the watts. Need help please. Thanx

get a kicker 2500 and run em 2 ohms.

get a kicker 2500 and run em 2 ohms.

so in other words your saying that if he does get a 1200.1, he will only get 600 watts out of it?

You would buy 2 Ohm subs (or dual 2 Ohm subs, single or dual 4 Ohm, quad 1 Ohm, single 8 Ohm, etc.....subs come in all kinds of voice coil configurations) depending on what kind of available power you have to drive subs with to make the most of what you have to work with.

Have a read through the stickied tutorials in the wiring section to gain a better understanding of what exactly the resistance value (measured in Ohms) of a given speaker means.

If the L7s that your brother purchased are dual 2 ohm subs (meaning that it has two voice coils that the nominal impendence of each is 2 Ohms) each sub by itself can be wired into a 1 Ohm or a 4 Ohm load.

With multiple subs it gets a bit trickier - here's the page I keep saved to my favorites for quick reference. Pretty handy guide, IMO.

Figure out the output capabilities (RMS ratings, though - peak power is an irrelevant number) of the amp(s) that you're going to use. There will be multiple ratings as power output differs from one resistance load to another, most times.

After figuring out what the best use for your application will be wire the subs to the amp accordingly and enjoy //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

speakers come in different ohmages to allow different wiring options when running multiple subs off an amp.

Nice reply Prowler, I was just gonna say "google speaker impedance". lol

YOu people dont seem to understand what I am asking.......What kind of an amp do I use. The speakers are rated at 750 rms. and there are 2. Now what amp should I get. Because if there are 2 speakers they can only bridged at .5 ohm and 2 0hm. If you can find a amp that will run them without blowing at .5 or being too expensive at 2 ohm i wil kiss you

Umm...an amp that's stable into a 1 or 4 ohm load?

My PG Tantrum 1200.1 would be perfect for those...

well it seems that you answered your own question on ohmage so go to ebay and start looking. this forum is all about educating so if you just want someone to do the shopping for you--its gonna cost and we take paypal!

So you say that I can use an amp that is 1 or 4 ohm.? The guide says only .5 or 2 though.

What kind of amp can run at .5 all the time(steet use) without overheating or blowing? Thats cheap?

 

[bonesninja 5,000+ posts]

no he's saying that the amp puts out the same power at 1-4ohms.

So these are SVC or DVC 2ohm coils?

 

[bonesninja 5,000+ posts]

i think all L7's are dvc.

how do you bridge a sub? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif get an orion 2500d
