How should i wire these?

[DR3W]

I have 2 MTX audio subs 4ohm DVC. And im looking at the Crunch GPV 2100.1 its a monoblock 2000W amp. How should i wire them? Parallel or series?

Or like one of these



?

to 1 ohm. youll get more watts out of the amp. thats how i have my single wired. 1 ohm.

so the bottom pic.

DR3W, this is a "6 of one, half a dozen of another" type of question. I will tell you right now that if you are after sound quality, keeping the speaker resistance as the amp sees it at 4 ohm is going to be better. Also, running the amp at 1 ohm is going to cause it to run hot (lots of current), which can lead to early failure as the components are also running hotter (electronics hate heat). But, the down side is that running at 4 ohms, you may not get as much volume out of the amp.

Granted, wiring up each speaker in an 8 ohm configuration also helps with your SPL levels as you are creating a longer effective coil which is going to help with throwing the cone around. This will lead to a harder thump using less power.

Either way works, just a matter of what factors are more important to you (volume or clarity).

Clarity is top for me. Cuz i really dont listen to my music loud at all. My stereo is always at about 35-40 pertcent volume. Because im going to get new speakers too. And eventually a nice double din HU.

Any way i could hook it up for the amp is at 2ohms?

I always buy amps that are stable to at least 1 ohm (.5 better) and then run them as low as possible, but my buddy always goes for 2/4 whenever possible

DR3W, the only way that you can run the speakers at 2 ohms is to get single voice coil speakers (SVC's) or if the amp outputs a low enough power, you only need to wire up a single coil on each speaker. BUt, like I mentioned, you need to make sure that the power of the single coil in each speaker is more then sufficient to handle the sub. An example would be if you have a speaker that each coil is rated for say 200 W RMS, you can run up to 800 W RMS if you used all 4 coils. So, any amp below 800 W RMS would work for these speakers. But, if you only wire up a single coil on each speaker, then you are back to 400 W RMS (200 W RMS for each speaker). I don't know the specs for the speakers that you bought, but it might be something to consider.

As for running amps into the 1 to 0.5 ohm range, most people do this to get additional power out of the amp. This is true to a point depending on the amp that you buy. If you get a true Class A amp, yes, by dropping the resistance in half, you double the power. The problem lies in that most amps made these days are not Class A amps (mainly due to the cost of making them, very expensive). So, most amps are what are called Class AB. So, they have a lot of the characteristics of a Class A amp, but not quite. So, what you will see is that the power may double for going from 4 ohm to 2 ohm, but when you step up to 1 ohm, you may only get 3 times (or less) from 4 ohms (vice 4 times). I've seen some amps actually loose a little bit of power when run at low ohms due to the heating of the internal components. So, without knowing a very specific manufacturer and model amp, it is hard to say what gains you may get from lowering the resistance. So, there is a bit of truth to both sides of this.
