I'm trying to find a good amp to match to my subs. I understand the concept of matching rms levels but its the ohms that get me. I keep reading everywhere that you can do this and that (different loads, run at different ohms, wire it this was, parrell that!). I just dont know what the best way is.

My subs are 2 10" kicker compvrs that run at 300rms@4ohm.

What amp should I get?

Do i buy a 2 channel amp or 1?

At what ohm level or load should I run at?

I'd like to stick with kicker amps but im open for anything.

 

Let me first state that I am pretty new the the game here as well, but I have done a lot of research on the subject. This helped me understand:

Basically , my undertanding is that if you wire a 4 ohm amp to a 2 ohm load it will produce more power but also work harder in the process, so theoretically a 100 watt amp at 4 ohms will produce 200 watts at 2. And vice versa.

 

You have 2, 4 ohm, 300WRMS capable subs.

You can run one of these on each channel of a two channel, 300W RMS into 4 ohm capable amp. Or two seperate one channel 30WRMS into 4 ohm amps. Or you can wire the subs in series for an 8 ohm load, which will reduce the power, or wire them in parallel which will double the power requirement, which means bigger amp and heat. You need to know before you put them in parallel that the amp you buy is stable into a 2 ohm load. Meaning the amp won't crap out with an early failure for drawing too much current. This is usually in the spec sheet.

Do you know how to put these subs in parallel or series?

RMS means the amp might actually be marketed as a '500 W per channel' amp. But it's RMS, or average Wattage rating is the operable one you need to pay attention to.

Critics are welcome if i mispoke here.

wont i need 2 of those?

 

Nope that amp should work fine for you provided you wire the speakers up in parallel.

 

i dont need an amp that produces 600rms x 1 @ 4ohm or 300rmsx2 @4ohm

 

oh your right get this one instead:

Bart would you care to explain this one. I'm dead tired.

oh and D don't buy that amp

 

Hoooooooold on a second here, Im confused. Are those subs Dual Voice Coil, or single?

If they are svc, then you need the power at 2 ohm.
If they are dual voice coil, then you need it at 4 or 1 ohm.

My understanding is that they are SVC; and the only reasonable option is to wire them in parallel for a 2 ohm load. The KX600.1 does 600wrms at 2 ohm. Not going to get any better of a match than that.

With that SX600.2, you would either have to wire them in series for an 8 ohm load, or put one sub on each channel, and you would only be getting about 150 watts per sub.

 

They're the dual coil subs

 

Ok, I was thinking they were single voice coils.

So, yes, you will need it at 1 or 4 ohm.

 

Ok, sounds like we got the Ohms cleared up.

How does a dual coil work? I remeber the cone being driven by a driver which was pushed by magnetic force created by a coil, but how does a dual coil work?

 

still that amp only does 300Wx2 @ 2ohm

Dont I need something beefer that will do 300wx2 @ 4ohm?

 

If these subs have dual 4 ohm voice coils then yu are going to be looking at an amp that can do:

300w x2 @ 2Ohm

with 2 dual voice coil subs you also have some wiring options that will also let you run an amp with these specs:

600w x1 @ 1Ohm
600w x1 @ 4Ohm

 

Styx man, two dual 4's cant be wired for 2 ohm final Only good choice there would be your first link
