Re: sterio codes

Best thing to do is call the dealer and tell them you replaced the battery and the car didn't have an owners manual. They can get pull one off their computer, they just need a S/N from the radio. If that doesn't work, I can tell you a different idea. Don't forget to leave feedback

I need to know exactly what type of system you have. Are is this an inline preamp. Or is this something that you want to connect directly to your stereo before your amp?

Where can I find the rca conection for my 2007 tahoe factory radio

It does not have one. Look at the REQ 5, from MTX. It will convert your 4 channel system to a 5 channel RCA, with a 8 volt pre out, which is better than most aftermarket decks.

Hi im after some help coz driving w/o music is no fun. Just done a sterio system upgrade to my car using mid-high end sony xplod components ie 6x9s in the rear, xm4s amp, 6.5s in the doors new head unit...

Congratulations on your new audio system. I will give you 4 scenarios: 1st. From your head unit, use the Fader to separate the front speakers from the back. (only front speakers playing) now using the balance separate the left from the right so only one speaker is playing. If the sound becomes more bass filled then you have a phasing problems which could cause cut out (protection) issues. Do the same for the back speakers, BOTTOM LINE: make sure that your connections from amplifier to speakers are all correctly connected where they should be.You will know that your speakers are correctly connected when the bass is richer while both speakers are playing as opposed to more bass when only one is playing. 2nd. Your head unit RCA output is of a certain voltage (V) [signal strength]. (1.2V, 2V, 4V, 5V) Lets say that your head unit has a 4V output, To match this up with your amplifier you must adjust the gain control on your amplifier to be at the 4V position. If your voltage output does not match your input voltage and the signal in result that is being sent is too high for the settings on the amplifier, you will over voltage your amplifier making it distort then heat up and most likely start cutting out to protect it self. this could also potentialy damage your speakers. 3rd. Check that the speaker cables are not shorting on metal anywhere, that includes the speaker terminals not touching the frame of the location that they have been installed. 4th. The cable size you are using is not adequate for the power needs of your amp. hope this helps. dreamsystems

I carnt remember the pairing coad for my bluetooth on my blaupunkt sterio

Most factory defaults are 0000 (Four Zeros). You can also email the manufacturer and see if there is a way to reset the code.

Ow do i hook it up to my home sterio system?

Not really possible, as a car amp requires a remote signal (usually a 'pulse' of 5 to 6 volts), to turn on.

Maybe you could wire up a small homemade battery/switch box to the amp to pride the switch on signal?

JBL CS60.2 Car Amp is fitted to new sterio but stays on 247 regardless weather the car is on/off or even when sterio is off... so stays on during the night ¬¬

The blue wire to your amp (remote signal wire) needs to be connected to the red power lead for your deck. Right now it sounds like you are connected to constant power on your signal wire.

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.
