3 4ohm 12's

[Brett2853]

I have 3 300 watt rms and 600 peak mb quart shallows in a sealed box. Would it be better to wire all 3 parallel at 2ohm's and use a 4 channel amp or series parallel at 2.7ohm's and use a monoblock?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gifView attachment 26553608

Use a mono block either way.

Usually, 4-channel amps are used to run door speakers instead of subs.

How big of a difference is the 2.7 and 2? What size amp should I go with to get full power out of them?

If you have 3 D4 subs I believe you can only wire to 2.66 ohms or .66ohms

 

[Brett2853]

I've only seen the 2 and 2.7 wiring. How do you wire to get that impedance?

 

[NinjaBass]

I meant to say 2.66 which you get from wiring all the speakers to 8ohm

You get .66 from wiring the speakers to 2ohms

There's no way you can get 2 ohms with 3 dual 4 subs or even single 4 ohm subs. Ninja has the correct final impedances if you are using D4. Check out the following link if you need some help figuring out your wiring options. Rockford Fosgate® - Woofer WiringWizard

well it might help to know if his subs are svc or dvc lol

Since he was talking about 2 different wiring configurations I assumed he had dvc

 

[Brett2853]

They are dvc. I knew I forgot something. But what size amp would yall recommend?

Usually cheap subs have RMS ratings based on the size of an amp they can take. I'd do around 1000w or less. A PPI P1000.1 would be a nice choice.
