need help on amp choosing

It's 2x200w rms @ 2 ohs (1x400w rms @ 4 ohms)... so definitely no.

You have two 600w rms dvc 4 ohm subs that can be wired together to 1 ohm at the amp... it would likely be the cheapest route to find a class D mono amp that does at least 1200w RMS at 1 ohm.

wall for $200 1200Wrms is going to be hard to get you can get the http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=18349

but it's not that good I dont think. I say go with the http://www.sonicelectronix.com/item_6522_Hifonics+BXi+1206D.html

it's 1200Wrms at 1ohm and I think it's better for the $$

im a newb at this so if i get a class D amp with atleast 1200watt at 1 ohm i will be able to get my 2 subs running off that amp at a good beat? dont i need a 2ch since i have 2 subs ????

The "mono" in monoblock is in reference to how many output channels it has - that being, naturally, one.

It has absolutely no bearing whatsoever in regards to how many subs it can adequately power.

For the answer to that you need to figure out three things (1) How much power does the amp make? (2) How much power does my sub or subs need per each? (3) Can the specific combination of sub(s) that I need to power create the appropriate resistance load on the amp for the level of power I am needing?

A monoblock amp could, in theory, run as many different drivers as you could physically wire up to it so long as you do not drop the resistance to such a low level that the amp becomes unstable.

on page 1 of this thread it shows the specs on my subs can you take a look at them please and let me know what i would be lookin at //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

As I previously stated, you have 2 subs that are dual 4 ohm voice coils each. The best route for you would be to wire the voice coils of each sub in parallel (giving each sub a 2 ohm load), then wire the 2 subs together in parallel (giving the amp their going to be attached to a 1 ohm load).

Refer to OPTION 1 of this diagram.

Either of the 2 amps (the Crunch GP or the Hifonics) will work great for your application.

Poke around on the forums here to learn how to set amp gains properly, and utilize the following forumula to get the desired amount of power from an amp that is capable of outputting more than what's attached to it can handle (say for example, two 600w rms subs on an amp that is capable of providing 1500+ w rms).

SQRT(WATTS * OHMS) = VOLTAGE

Simple put, you take the ohms at the amp and multiply by the watts you want to output, then find the square root of that result. The final result is the voltage desired from the amplifier's speaker output terminals.

SQRT(800*1) = 28.28V
