If what you're telling me is correct you're trying to drive a stereo sub -woofer with a mono amplifier. If so, that could be a bad situation for the amp, if the voice coils are not wired together correctly. Before we go too far, I have some questions I need answered.
1. Is the MA unit an M1889i?
2. Do you have the 4 terminals of sub-woofer tied together. For example the 2 positive terminals are tied together & the 2 negative terminals are tied together?
3.How do you supply 12VDC to the amp?

While I'm waiting to hear back from you, I'll try to draw a schematic (wiring diagram) of the way it should be wired for your particular setup that I'll send to you.

800 watt mono block sony xplod amp blowing my dual coil 1500 watt subs


if the wiring to the sub is correct, then you have something wrong with the amp itself... something is power surging to the subs which is causing them to blow

I Have a Sony Xplod 800 watt amp and 2 12 inch Sony Xplod subs


You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

Getting my son a sony xplod xm-1652 2 channel what subs would sound good and the things says 1000x2 and 500x2 what is the truth


165 watts x 2 @ 4ohms and 200-230 watts@ 2 ohms or 400-460 watts bridged into a 4 ohm mono load is what the amp will actually do. A single 12 inch sub or a pair of 10 inch subs or 12s would be great

Hi mate very nice amp you got there here is the specs for it



Model: MA Audio HK401SX

1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS @ 1 Ohm Mono

1 x 500W RMS @ 4 Ohm Mono
Fully Unregulated MOSFET Power Supply
2 Ohm Stable @ Mono

if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck

What is best amp to run 2 12 inch cvr's


12In Kicker CVRs
are Dual Voice Coil, and You can run each voice coil around 200 Watts RMS

So each sub will have a 400 Watt RMS and 800 Watts peak.

Now since you have 2, Your total will be 800 Watts RMS and 1600 Watts Peak.

I would get really any amp that sits at around 800-1000 Watts RMS.

These are kicker but they are low end so i wouldnt push them to the extreme.

1000-1200 Watts RMS Max and but keep the Gain down on the amp. They will hit no doubt but i wouldnt push these subs or you will be disapointed in the long run.

I would get a Fosgate or MTX amp.

You can get any amp really but find something right around 1000 Watts RMS and it will push those well.

You can go mono block or a 2 channel, just depends on how you want to wire them.

Be careful though. If your running them bridged right now with your mono block, do not run them parallel bridged on a 1000w RMS Amp, you will blow them so fast lol

(RMS = Root Mean Square. Or in other words is the continuous wattage being sent from the amplifier to the subwoffers)
