i recently bought a 12" cvr kicker subwoofer dual coil off of ebay and i want to know what you guys suggest of which amplifier i should use. the sub is a 400w and i was planning on putting it in my honda accord with the stock speakers and a after market head unit which i haven't decided on yet either.

your help much appreciated

Look around on ebay for a 400w RMS @ 2ohms amp. I bought the same sub but the 10'' version. I paired it up with a Clarion apx1301. Works great!

Though, I'm going to suggest a class D amplifier. Mine makes a lot of heat.

so the sub wont blow if i buy a amp that is 400w and the sub is also 400w?

and what does it mean if a amp is mono or multi channel?

No, Matching RMS rating is the best thing to do. However getting a larger amp (500w RMS) gives you some head room.
From what I've read on here. One forum member was pumping 1000w RMS through his CVR.

Mono = one channel.
stereo = 2 channels.

If you read the spec of the amp it will clear it up. Some amps are marketed at 500w two channels. So you might think, is that 500w PER channel? or together?

okay thanks. so is my sub mono or stereo? because i know it can be bridged in series or parallel circuit

I think you're getting mixed up here.
First, What impedance (2ohm or 4ohm) sub are you getting? I assumed, and I shouldn't have.

Dont think of your sub being Mono or stereo.
An amp with 1 channel can drive as many subs as you want, as long as the impedance is correct for the amp. Same goes with 2 channel amps.
Bridging an amp is when you have a 2 channel amp, say 250wRMS per chan, and you bridge them to make a 500w RMS 1 channel.

When you say "i know it [your sub] can be bridged in series or parallel circuit" your talking a bout the voice coil. Which isn't bridging. Series or parallel will give you different impedance's. Which will determine which amp you'll need to get.

this picture is what my manual says and i dont know which amp will work with series or parallel wiring

All amps will work with series and parallel wiring. But We still need to know the impedance of your sub. That manual is for both models of sub. 2ohm DVC and 4ohm DVC.

If you have the sub already, you can use a multimeter to read out what the impedance is.

okay this is the part that confuses me. in the manual it says that each cvr sizes are 2 or 4 ohm and on the back of the sub it says 2 ohm. but the subwoofer is dual coil so is it 4 ohm in total?
