Re: XM-2252HX

The idle current (bias current) of the output section is set at the lowest point that will prevent notch distortion. Setting it higher will only make the amp run hotter. It has nothing to do with the protection circuit.

You should check the woofer's DC resistance with an ohm meter to confirm that it's close to the rated impedance. You should also check the wiring to make sure it's not shorting to ground (which could cause the amp to go into protection).

I have Sony xm-2165gtx amp 165 watt rms x 2 at 4 ohm 200 watt x 2 at 2 ohm 400 watt x 1 bridge output at 4 ohm stereo or bridge mono output 4 ohm stable in bridge mode this mean can't go lower then 4 ohm...

You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.

I got Sony Xplod XM-ZR704 700W 4/3/2-Channel Car Stereo Amplifier and 12" sub. it play good for continuous 2 hours but after that starts tripping and goes on off. i checked all wires and connections.

Amp is probably over heating. Make sure the ohm load of speaker is good for that amp. This amp is not really built to handle a bridged 2 ohm load. Make sure ground wire is clean and tight to the body chassis.

How should i arrange the wiring on my xm-zr1852 xplod amplifier to get the best performance out of my 12'' audiobahn subwoofers?

it depends on the impedance of the subs-if your subs are dual 4 ohm coils then you can parallel the coils which will give you 2 ohms per sub- you could get max performance from your amp by just wiring the 2 ohm speaker load to each channel of the amp which will hit them with about 200 watts rms each. another way to do it is to wire the coils in series which will make each sub an 8 ohm load and then parallel them together and that will show a 4 ohm load -which you can use to run the amp safely in bridged mode. This will give you exactly the same amount of power to your subs as in 2 ohm stereo will. so with your amp being 2 ohm stable in stereo or 4 ohm stable in bridged mode- those are the numbers you want to hit for maximum"safe" operation

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

Amplifier loads

Hello ronnieyannon,
A single 4 ohm speaker wired to each channel, like you have them wired, presents a 4 ohm load. And it appears that you have them connected properly. The 401s is only stable to 4 ohms when bridged, so if you were to parallel the 2 4 ohm subs in bridged mode, the load would be 2 ohms and the amp would most likely overheat and go into protection.

I'd wire them the way you have them wired.

Each channel of the amp outputs only 100 watts into 4 ohms. That is adequate for regular full-range speakers, component speakers, mid-range drivers, and even some small subs. But it is a little low on power for most subwoofer applications.

Hope this helps.

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

Protection light

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
