im kinda new to the sub world and im looking at buying 4 10'' kicker cvr subs that are 400 watts rms and 800watts peak a piece. im looking for a decent amp to go with and i found a ma audio amp that is 3200 watts and 1600 watts continuous power. it is a 2 channel amp. is it able to be hooked up, i really have no clue

Fist welome to the fourm, Yes you can hook up those subs to your amp. However just keep in mind that the amp you have in mind will not put out that kind of power. I would suggest looking at getting a better amp name brand amp for your system depending on your budget. Even if that amp could generate that power you would need to up grade your stock charging system in your car,assumeing that it is stock. If it were me on a limited budget again I don't know your budget. I would either opt for 1 good sub in a proper built box and a really good amp. Or if a just have to have 2 good subs with a really good amp. Or you can just be happy with the system that your wanting to get it's really up to you, that was just my 2cents

wire the subs in series and bridge the amp. ur not gonna quite get the power u want but thats the best way in my opion. what kid of car are u puttin this in the residencey will also make a huge diffrence

simply stating to wire the subs in series is no kind of helpful advice.
First off what impedance are the subs that you are going to buy???
What minimal load is the amp stable at??
then we can go on to wiring configurations from there

well first off i mean paralel. and it does help cus if it drops the ohmage lest resistance more power if he wants to stick to that set up so series advice ur right it is but parallel will help the situation

Sweet! more power!!!!
Dude don't post if you don't know what your talking about.
By that thinking 4ea 4ohm svs subs in parallel =1ohm If they were 2ohm subs = .5ohms mono with a very good chance smoking his amp if it is not stable that low witch I doubt that it is.
If they were duel voice coil it gets even lower. Bad advise.
If you wire 4 svs in stereo then you get a 2ohm load per channel in that fashion. So yes it dose matter what the impedance of the speaker are and how they are hooked up.

heres the info on the subs that i was given--- Freq. response 25 - 500 hz and heres the info on the amp... - Power Output 1600 Watts RMS Mono
- Power Output 2 X 800 Watts RMS Stereo
- Platinum Plated Connections
- Quiet Fan Cooling System
- High Quality Power & Protection LED's
- Thermal / Short / Overload Protection Circuitry
- 0-18 dB Variable Bass Boost
- 40-250Hz Variable High Pass Crossover
- 40-250Hz Variable Low Pass Crossover
- THD @ 4 Ohm <0.05%
- THD @ 2 Ohm <0.01%
- S/N Ratio >90dB
- Channel Separation 60dB
- Frequency Response 20-20kHz
- Input Voltage Range 200mV -4V
- Input Impendence 10k Ohms
if this will help any and it will be going in a 99 dodge stratus 4dr

Here check this page out I am too tired to think right now but play with this page some. It will get you in the general direction if your set on 4 subs one of the smarter people might still be up. On the left side of this page in the blue there are several items to help you out like the calculator that this sends you too.

so if he goes with your "advice" (haha wow) he will end up with a final load of .5 ohms...with will then be a .25 ohm load PER CHANNEL.
Damn..lower ohms = more powa FTW!! Lower resistance doesn't always means more power.
P.S. Good advice absolutepower...good advice

I'm not sure exactly what amp that is - I'm guessing the HK1398 or something similar... You can bridge the amp and run all four subs at 8 ohms, or leave it in stereo, and run two subs per channel at 4 ohms. The power will be the same, but at that impedance you can't get 1600w out of it. I would be surprised if you'll get 800, or 200 per sub. Do this on each channel.

STEE-RIKE ONE! Residency? Do you mean the kind of car? That will make NO difference to whether you wire in series or parallel or bridged or stereo.

STEE-RIKE TWO! The correct phrase is "drops the IMPEDANCE". "Ohmage" is adverb form or the Bhuddist centrist chant - ooooohhhhhhmmmmmm.

Around here we do things a little bit differently. We like to get ALL the information available (and yes, sometimes, it's like pulling teeth...) THEN we offer solutions. This ain't your daddy's car audio forum (.com)
 ------------- It all reminds me of something that Moličre once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

if that amp isn't really any good what amp or amps would you all recommend to push those 4 subs, i am on a kinda limited budget too

Let us know what your budget is for the system your wanting to put together and your sure to get several systems. And what do you want out of it a good sq, bass system or what have you. What items do you currently have? That would be alot of help along with your budget of what you want to spend and willing to spend. Since you can always just get a few quality items then as your able to add other quality items.

im for sure goin with the four kickers, and the only thing left that i need is an amp, and box which ill build myself, my budget is down to about 3-400, and i mainly want a bass system

I'd check out the factory renewed Kicker zx1500.1 at hifisoundconnection.com. Looks like about $380 shipped to MO. Power would be just about ideal for those subs.

I agree with n2audio go with a 1ch amp that kicker vx1500.1 sounds like a steal, my brother has 4 kicker cvr's with a crossfire 1000d in a ported box. Let me tell you it hits like a champ, but you will need 2ohmdvc to get that 1ohm load
-------------
WELL?
