Re: protection mode override

If you have your subs wired to the amp in a bridged configuration, try wiring one to each stereo channel instead. Also, make sure your ground wire is secure and connected to a clean, solid metal part of the vehicle body with the paint scraped off. If this doesn't work, disconnect both subs and try connecting only one at a time; one of the subs may have a problem that is shutting down the amplifier.

Green light comes on for a sec the red light comes on,1200 watt sony xplod amp 10'' Orion sub,I think the subs right around 3000 watts. What's wrong?:(

Your Sony Xplod amplifier turns on briefly (green light) then possibly senses a mismatch between the nominal output impedance of the amplifier and impedance of your Orion sub and goes into protect mode (red light) to prevent internal damage.

I have two sony xplod 12" speakers wich can hold

You only gave us the model of the amp so I will make an assumption that your 12" subs are the Sony XS-GTX120LW. First, they cannot hold 1200 watts a piece. They are meant to be powered with 350 watts RMS. They will hold 1200 watts peak. That means that 1200 watts for a few seconds will be ok. Past that and kiss them goodbye!

Next you indicated that bridged the amp. Since the subs are both 4 ohm single voice coils did you wire them in series or parallel?

It sounds to me like you wired them in parallel resulting in the amp seeing a 2 ohm load. The amp you referenced is only stable when bridged at 4 ohms.

Has the amp begun working again once it cooled down? If not you could have fried the outputs by having the resistance too low.

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.

Can I run 8 speakers and 1 sub through 1 1200watt 2:1 Sony Xplod?

asuming the 8s are 4ohms each; wire two in series and that gives you 8ohms then two more in series then you put those together in parallel and it gives you a 4ohm load. repeat with other four for the other side. you should then be able to bridge the sub

series; posative of one speaker to negative of other speaker and that doubles your ohms

parallel; posative to posative negative to negative and that cuts the ohms in half

How do i bridge 3 subs to a 4 channel amp

My information shows the XM-1652Z as being a 2-channel amp. It will not be stable below 4-ohms in bridged mode. For best power, your subs will need to be 2-ohms with all 3 wired in series. This will present a 6-ohm load to the amp. After wiring the subs in series, connect the positive speaker wire to one channel (+) and the negative speaker wire to the other channel (-). For the 1652Z no other wiring is necessary. For subs you will also want to set the LPF (80Hz) switch to the "ON" position (to the right).

Keep in mind that the rated output is only 400 watts RMS at 4-ohms in bridged mode. That's kinda wimpy for 3 subs. You would probably obtain better results from two 2-ohm subs, each connected to a separate channel. That way each sub would be getting 200 watts RMS, still low but there's lots of good subs that will sound pretty loud with 150-200 watts

Support Question about RMS

you are going to need an amp that can supply the right amount of rms power to make it sound good. these sony subs are rated for 380 watts rms. so in order to find an amp that will supply two, you must multiply that figure by two. so you will need an amp that can supply around 500 to 750 watts continuously (or rms). also you are going to want an amp that is either class d or class ab rated. these amps are built to push subwoofers exclusively and will give you the best efficiency and sound out of your subs. you will also want to get an amplifier is a monoblock amp, and not a stereo amplifier. make sure the amp can put out that rms rating at 2 ohms as two 4 ohm speakers equal 2 ohms wired in parallel. i have a kenwood kac9152d that puts out about 2000 watts max at 2 or 1 ohms (900 watts rms) that i used with my two sony xplod 10's for about 2 years. it was kick ***! now i dont know if you need that much power but they will handle it as long as you dont push them too hard for long periods of time, otherwise you might end up blowing them up! (depending on the box size that is, and the quality of it as well...)

i have years of car audio installation experience and can help with setting up and wiring any mobile entertainment system you can imagine. may i ask what kind of music you listen to and what kind of box do you have for these subwoofers?

if you have any questions email me at

High distortion

The head unit may be rated at 200 watts but it cannot produce more than ~20 watts of real power per channel. There's no way that it can drive the high end speakers to a level that will be needed to compete with the subs on a 1000 watt amplifier.

Boss chaos 150 200 watt that shows light but doesn't produce sound

If this is the CH150, it's not bridgeable. Try connecting it normally (one speaker per channel) to see if it will produce output.
