How to hook up speakers correctly for proper impedance

i believe you have a built in amp in receiver, so just do not push it, and its fine.

The amp needs an RCA input to communicate with the head unit. SOLDER the wires that come out of the head unit for the front speakers to the SNI-15, making sure that the polarity and right/left is correct. Do this for the front and rear speakers if you have a 4 channel amp. Cut the wires if you add new speakers and run the new wire from the speakers or sub box directly to the amp, or skin back the wire insulation and tap on if you use the factory speakers :( then plug your RCA cable from the SNI-15 to the input side of the amp. Don't forget that most new cars have their own amp so you might have to locate it and bypass the speakers wires around it. Don't make a mess in case you have to put everything back to factory for resale. You can avoid all this by installing a new/modern head unit with built in RCA outputs for front, rear, and sub woofer. I hope this helps. Ray

Rum a fused power line to the Battery, a fused remove on from the head unit or keyed fuse in the fuse box, ground it to the chassis, hook up the signal source using speaker wires or pre-amp cables. Bolt it down so it wont more while driving

Sounds like possibly the Amplifiers built in protection circuit is active

If you know the speaker is good then check the speaker wires an make sure none of them are shorted out or pinched somewhere touching the metal of the car... if you are using the factory speaker wires then try a new wire ....

worst case scenario could be short inside the amp? but you can easily tell if that is the problem by disconnecting the speaker wires from the amp to see if the light stops blinking

Hope this info helps but cant be exact without knowing what type brand / type Amp you are using

Alot of amps and speaker crossover have protection circuits built into them so when you turn up the music to much it's there so you don't blow your speakers. Try turning down the gain on the amp if that does'nt work check your speaker wiring for out of phase meaning
+ - wires are backwards. To test them use a 9v Battery touch the speaker wire to the + - terminals on the battery if the speaker pops out it's inphase and good if it pops in it is out of phase reverse wires and if all that checks out get a stonger amp.

remove all speaker connections to your amp. MAke sure the inputs are driving all 4 channels, and that the built in crossovers on the amp are all set to full range. Conect your full range speaker to each output channel one at a time and verify there is oputput on all 4 channels. If all is ok, then connect your rear speakers to the front(a) outputs of your 4 channel amp, and then use the second 2 channels (rear or B) bridged to drive the sub. Re-configure the crossovers for highpass for front (to drive your rear speakers) and lowpass for sub. This is the proper way to connect a 4 channel amp with a sup whle driving 2 full range speakers.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally, the wiring and speakers need to be checked. If it still shuts down, the amp likely has blown output transistors.

This radio can not use a common ground. If your speakers are all grounded together you will blow up the amp IC in the radio. The negative speaker wires run at about 6 or 7 volts and so do the positive speaker wires.

Trust me, run new speaker wires, do not common ground any of these speakers

If this was helpful a good rating would be appreciated.

My experience has been for this configuration, is that the red wire is your +5 volts, the green is right, the white is left, and the black is the ground for the supply and both speaker grounds. Hope this helps...accordianman
