My deck doesnt not transmit signal to my amp. Is this an rca cable problem

DOUBLE CHECK YOUR RCA CABLES. MAKE SURE THEY R GOOD & THAT THIER IN THE RIGHT SPOT ON THE AMP AND RADIO DECK.IF YOUR LIGHTS COME ON. THEN TRY THIS........ IF THAT DOES NOT WORK. CHECK TO SEE IF YOUR SUBS R CONN IN THE SUB BOX.IT COULD B SOMETHING THAT SMALL

i assume you want the sub and amp for listening to music and not the onstar itself, just the vehicle has onstar? if thats the case the easiest way would be to hook a line level converter into the rear speaker wires (both right and left) this gives you a RCA jack output to connest your rca cables to to send signal back to the amp. run power to the amp as described in the wiring kit directions and hook everything up as the amp requires. the rca cables would go to the "in" on the amp and you can adjust the line level converter for output voltage ( increasing the level increases the volume before the amp, so be easy on the adjustments or you could blow your speakers.)

Check your RCA's from the amp to the deck, make sure it's on an output not an input on an aftermarket deck,and the input, not the pass thru on the amp. If you have it hooked up to a factory deck, you've opened a whole new can of worms! If its a factory Deck; Post the make and model of the unit if you can find it, as well as the vehicle year make and model. I get as much info as I can on it and walk you thru the details. If it's aftermarket and you've checked the above, post the make and model of the deck and I'll do the same. Hope this helps

If there's only a single sub-out RCA cable, you have two options. The amp may have a manual switch that puts it in Mono mode, in which case you only use 1 of the 2 RCA jacks. The other option is to go get an RCA splitter. This will take your single sub-out cable and feed the exact same signal to both left/right of your amp. Either way, you get the same result. If the 1200W amp is for your sub(s) only, you should set the high-pass filter and subsonic filters to help your bass "hit harder" and cleaner.

go into the menu screen on the pioneer unit and go to setting if you have a loud function there turn it on.... if that doesn't activate the amp ...(did you hook up the blue wire from pioneer deck to amp and run it threw the car to the amp)..if no than your pioneer deck does not realize there is an amp present in system....... if yes scroll threw menu till you see audio look for Sub Woofer or Amp you may even have a button on pioneer deck marked SW go press it and turn amp to on this will provide signal from pioneer unit to amp if this doesn't work other thing could be you hooked RCA to AUX input (but if you have a SW for RCA plugs on back of unit make sure the RCA wires are in it) the loud or SW button should activate it (if there is only F and R for RCA plugs on back of unit use R hope this helps)

First check the speaker wire from the amp to the sub, see if it's connected right. Second check the rca cables that goes from your amp to the back of the deck. I f both wires are still connected fine try to replace the rca cables. If it still doesn't work the rear out put at the back of your deck, where the rca's are connected are bad. FYI deck is bad.

first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
cheers

it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs

The RCA cables are for leads from your deck to your amp. Assuming you have an aftermarket deck, pull it out of the dash and look at the back. There should be a red out put and a white output for your cables to plug into. They're sometimes labeled left and right to help you make sure you hook up the amp right. If not, just be sure to match them up between the deck and the amp. If you have the stock deck in there, it's unlikely that you'll have RCA outputs, as most stock decks I've seen do not. As for the protection light being on, your amp is most likely shorting to ground somewhere. Be sure you don't have it screwed right to any metal parts of the car, as this can cause problems. Most amps have a section in the manual warning against this and the problems it can cause. Some amp manufacturers don't say anything about that or say that it will be safe, but, as a rule, I always just play it safe and mount it either to my sub box or on a piece of plywood or something that is secured in the car. Also, make sure that the in-line fuse on your power lead isn't blown, and most amps have one or more fuses on the side of them, so check those, too. If none of these things are wrong, then it might be an internal problem and I can't really help you with technical stuff. Hope this helps. Please leave feedback, too.

The first thing to try is disconnecting ONE of the two subs. See if you get more bass with a single sub than with both. If you do, re-connect the second subwoofer, but reverse the (+) and (-) wires.
