It connects to a fused, switched 12 volt power source; one that comes on when the radio comes on, preferrably the blue/white wire from the back of an aftermarket stereo.

THE GOAL HEAR IS TO DETERMINE IF THE INSTALLATION IS CAUSING YOUR PROTECTION FAULT OR IS IT THE AMPLIFIER ITSELF HAVING INTERNAL DAMAGE. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL GOES INTO PROTECTION AND YOU HAVE VERIFIED THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%, THEN THE AMPLIFIER WILL NEED TO BE SERVICED. ANOTHER PROBLEM WHICH IS A LITTLE RARE, IS THAT SOMETIMES THE RADIOS REMOTE OUTPUT WILL SAG BELOW 11 VOLTS AND THE AMPLIFIER WILL NOT TURN ON. IF YOU CANNOT MEASURE THE REMOTE LEADS VOLTAGE, SIMPLY DISCONNECT IT AND TEMPORARILY INSTALL A JUMPER BETWEEN THE POSITIVE TERMINAL AND THE REMOTE TERMINAL OF THE AMPLIFIER AND THIS SHOULD FORCE THE AMPLIFIER ON, BUT IF IT DOES NOT, IT WILL DEFINITELY NEED SERVICE, AS YOU HAVE TOTALLY SIMULATED A BENCHED CONDITION THAT IS TOTALLY INDEPENDENT OF YOUR INSTALLATION. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

the amp will need to be repair because it has a fault that it is seeing internally. so not much you can do other than buy a new amp or get that one repair. probably cost effective to buy new. hope this help. good luck

Hola morebass, Aquí está el acoplamiento al manual.

¡Esperen que esto ayude a mi amigo hispánico!

disconnect audio inputs and outputs and see if one of those are causing it , if it still does it with all audio inputs and outputs disconnected then there is a problem with the power amp

It sounds like the amp has shorted output transistors. They would need to be replaced.

That amp seems to support 2ohm and 4 ohm loads. You cannot get down to 2ohms with 2 8ohm loads (subs). So, you need to wire them in parallel so that the load is divided among the resistance of their voice coils (2 8ohm paths means the driving circuitry (amp) experiences 4ohms of resistance because ... physics, basically). Wire the + and - terminals of the subs together and attach them at the amps + and - speaker output terminals. DO NOT run them in series. 2 8ohm loads in a row means the amp sees the loads added together, 16ohm. And its not rated for that, you could blow the amp by making try to drive a load that is too 'heavy' for it. the turn the amp gain all the way down, turn the head unit up until you hear the normal sprakers start to distort (that f@rty worbbly muddy sound), then turn the volume back until it goes away and the full fidelity (faithfulness to the input signal) returns. Then turn the amp gain up until the subs distort, and back a touch until they stop. Turn the system back down at the head unit. Your system is now balanced to the maximum volume it can reproduce, adjust to taste from there. And remember to thump responsibly.

I looked up the specs for the amplifier

• 4 ohms: 85 watts x 2 channels
• 2 ohms: 125 watts x 2 channels

So it will take 2 ohm speaker loads, therefore you can parallel 2 speakers together, that is to say connect 2 speakers to the + and - terminals of the left channel and 2 to the right. 4 ohms paralleled with 4 ohms = 2 ohms So you are OK

Take the peak to peak power rating and multiply it by .727 that should be the RMS watts. You don't have to worry too much about new stuff, but if you are using an older stereo amplifier that is rated for 8 ohm speakers then you should not use 4 ohm or they will pop the finals in the amp. You could use 2X 4 ohm speakers in series on every channel and it should be ok.

the amp probably got to hot and had a thermal shut down witch will have to be fixed by a professional.

The radio code is a security feature that's meant to deter theft, and it's unique to each vehicle. If you've lost your code, you'll need to contact a Nissan dealership or service center and provide proof of ownership. They should be able to help you retrieve the code. Please do not attempt to use codes from the internet as incorrect attempts may lock your radio.

I have the same radio now with no Bluetooth am trying to get Bluetooth on it too without having to buy another radio. Please help.

First thing to do is check to make sure that the batteries are properly charged.

Second, make sure that you have a clear line-of-site to the IR transmitter. Infrared (IR) works the same way that your TVs remote control works - if the signal is blocked, then you will not hear any sound.

Third, make sure that you are in the rear seat of the vehicle when listening to the sound. The IR transmitter only transmits to the rear seat, so you will not hear any sound if you are sitting in the front seats. This is a common problem that i see.

Lastly, make sure that the heapdhones you purchased are compatible with your 2006 2007 2008 2009 or 2010 Toyota Sienna. Remember that some older models require RF headphones, not IR headphones. I checked http://www.audiovideo2go.com for compatibility before I purchased my headphones. They have a useful listing of all the headphones and models of vehicles they are compatible with.
