Looking for power and speaker connectors

that amp is pretty powerful and will be great to use in your own car. YES
That is a great amp Don't trade or sell it its a great unit and worth around $250.

Speakers don't plug into inputs. Check your work.

Try powering it up with nothing attached, then proceed to attach things (like a speaker to the speaker terminals) and see what happens.

No!. If you disconnect it from power, you need the code to turn it back on. Check your manual before doing anything! that's the #2 problem reported on this site!. Chances are good that you have a bad wire at a door, or a bad speaker. Take it to the installing shop, they warranty their work. Hope this helps.

good morning and welcome to fixya. not a bad setup you have here at all, you ned to start by checking the speaker wires inside the box to the connector inside and then the wires from connector to amp on outside. if everything looks fine there, then you need to check the amp for power out of the rca plugs to make sure the channel is not dead. if you are looking for a new amp you can try several different ones from fosgates new line up to soundstream's. im running 4 polk momo 12's on the tarantula amp and love it. they are great amps. hifonics also has a new line up pretty cool stuff, heard really good things about there stuff to. good luck and let me know so i can help you out.

Yes, you need to plug in a 4 pin FLoppy Molex connector. Your power supply should have at least one. The power connector is right next to the Floppy Drive connector.

Also, the Floppy connector goes in with pin 1 (The red stripe) to the left looking at the unit from the back (furthest away from power).

There is no manual to speak of.

As an alternative cheap solution, if you have the following available you can do as I've done.
I used an old burnt out ATX power supply 24pin motherboard connector, cut all the wires of about 10 inches and then cross sliced the connector up into 2pin connector pieces. Worked perfect, saved me $ and made some great recycling use of an otherwise useless PSU.

Oh, my goodness.  I have the exact same problem, and it just happened to me today as well, same model.  The fifth prong got bent in while I was trying to plug it back in after diagnosing a different issue (speaker volume would randomly jump up and down regardless of audio source).
It looks like a PS/2 style connector with one of the top pins missing, so I thought about taking an old PS/2 plug and grafting it on after breaking off one of those pins, but the center plastic block on the PS/2 connector is unfortunately keyed differently than the speaker plug (it's lower down on the PS/2 plug).

that is actually a sign that the reciever is bad. it usually means the amp is blown. Not in the sense that it wont work. But its overheating and thats where the problem lies. for this recieve it only costs 130 for the pcb board that goes bad. I know no one likes to hear that there stuff is broken. But when i worked for Square Trade i seen a few dozen of these units come through and it was always the amp which can still be serviced by yamaha. -Thanks Nate

I have an extra unit. I don't have the magellan road mate manager. I would be willing to trade the whole unit if you could get me the magellan road mate manager cd. I hear there is another one that comes with it that would be great to have also. I have tried everything to get these cds but to no avail. comment here or email me at [email protected] if you are willing to do this.

what really matters is the quality of the usb speakers. check specifications such as wattage first and find reviews if possible. however usb speakers will probably not come close to separate speakers. i'd recommend buying a cheap sound card ($20 or so). these work great overall. $20 spent on a sound card will be a better trade off than $20 spent on speakers. just use your old speakers with the new sound card and you'll have plenty of power. after this i'd recommend headphones as they work great in this case. finally moving the sound card would probably work fine, but i have doubts.

hopefully that helped
