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

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---

Dual voice coil

4 ohm per coil

400 Watts RMS

800 Watts max

Freq. response 25 - 500 hz

Mounting depth 5-7/16"

Mounting diameter 9-1/4"

Spring loaded terminals

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 @ 2 Ohm <0.01%
S/N Ratio >90dB
Channel Separation 60dB
Frequency Response 20-20kHz
Input Voltage Range 200mV -4V

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.
