Yeah I think the amp will be fine for you. I would definately run it at two ohms to get its best power and efficiency. With the amps last year I know they were all recalled there was something wrong with them, I forget what because we only had them in our shop for like 2 weeks. Anyway Hopefully you'll be running each of your subs at two ohms, you should be fine with a "600 RMS" going to each. Hope that helps....

Yep, thats why im planning to do, run it at 2 ohms, to get 600W rms...

You will then also open up a possible can of worms by using two subs off of two amps. Unless the person who is setting up the system for you has the aptitude to do it properly and knows how to level match and crossover match, I would suggest one large class D amplifier. If you continue on the path that you have chosen, that's great, we can help you along. Start by making 100% sure that each sub has it's own enclosure, the subs cannot share the same air volume. Next is current demand, two amp draw more current than 1, can your vehicle afford this? Wiring, two amps use more wire than one. Space, I'm sure you get the point. RCA signal splitting, most sub amp sum mono the left and right inputs, now you infact have less signal available (in most but not all cases). Just some things to ponder.

I agree with forbidden you will not get the same voltage or signal across the two amps. It's very hard to set up a system for two subs with a different amp on each. I would reccomend that you get a different amp and something not pioneer. While I like them they have no balls. The last big amp had a recall because the board would overheat and was known to catch on fire!

What amp Could match my subs. they are rated 500W rms.?

I have right now Two bazooka amps connected to the subs ( I sold then). they sound great but i was having troubles with the setting, because the way i have it connected is this.

a pioneer AVH-P6500DVD connected to a digital processor Pioneer DEQ-9200 and to the amps....

Your subs are dvc 4 ohm subs, thus here are the possible wiring scenarios.

all parallel = 1 ohm (recommended) - need 1 ohm mono class D sub amp

series / parallel = 4ohm - need monster 2 channel class AB amp

parallel stereo = 2 ohm stereo - need monster 2 channel class AB amp

For the record, 2 ohm stereo is the same thing as 4 ohm mono. One of the amps I would consider for this is the Rockford 1051S or similar.

There are many good class D mono sub amps that are designed and engineered to operate at 1 ohm mono. A favorite of mine in the Concept CD1210, Lightning Audio X1.1000.1D and there are a whole pile of others.

Here is a wiring diagram for the two methods.

	Wiring Option #1
	Wiring Option #2

dont knock the pioneer amps. it wasnt the mono amp that caught fire, it was the big 2 and 4 channel units. The mono amps you have are brilliant units. Plug em in ,play it loud.
