I walked into maplin to buy some decent but cheap speakers to full in the holes in the parcel shelf, like a numpty I am I went for the 170watt speakers and only realized after fitting and wring the speakers to the head unit they werent working and looking at the box it said 170watt.

So i need some advice wiring a amp up to power the rear 2 6" 170watt speakers up and what kind of amp I shall need.

Thanks.
 
They should at least make a noise, although having them pulled into the HU isn't the best idea as they won't be getting much juice out of it.

To put an amp in your car, you need to run a power lead from the battery to the amp, an RCA lead from the HU to the amp, a short earth lead from the amp to some bare metal in the car, and connect the speakers. Personally I'd trawl eBay for one with around 100W RMS.

170 Watts is just the maximum input power*. You certainly don't need an amp to drive them as they will be perfectly happy being connected directly to the head unit.



* The maximum input power of cheap speakers is often grossly exaggerated. RMS power is the number you need, not "music power" or some other stupid made up term.
 
As others have said they should work no problem, so check your connections but firstly check the front/rear fader is not set fully forward ;)
 
this is where having a multimeter comes in handy. I remember replacing the 5x7s (or what ever) in the back of my escort with 6x9s (good ol' jigsaw cutty job to get the holes bigger xD ) and having to redo some connections and using the multi meter to check i had gotten the wiring right :) think I have some 150w pinoeer 3-ways or what ever, head unit put out 55/60w per channel i think so obv cute a bit under the max power but they gave decent sound up to reasonable levels... when really cranking them up with lots of bass is when they began to lose sound quality and an amp would have been needed :)
 
Ok checked the wiring and even bought a new phono cables to make sure it wasn't that and still no sound. Wiring 1 speaker directly to left and the other speaker to the right is this correct way?
 
not an option in the head unit to enable rear output? it might have two settings for direct out and possibly to an amp so you'll need to check and select the direct out if it's an option.

try using a multimeter on the speaker end of the cables, check resistance for a closed loop and try playing songs and checking for voltage that there is signal coming down the lines.

Yea I faffed around with the Pioneer DEH-4500BT and only found the fader or Subwoofer option. Gutted go out now to mess around looking for a cheap amp to drive the buggers. :mad:
 
No you haven't - youre making a balls of it somewhere. It sounds like you don't have a clue so either post some specs of what kit you have or save yourself some brass and take it to a car audio shop and get them to do it properly. :)
 
Op if you simply stick the spades back on one of the originals does it work? What's the car, it doesn't have any sort of active system I assume?

This. You're doing it wrong. :D
 
This is what I got...

Peugeot 106
Pioneer DEH-4500BT
FLi F15 5" 3-way 60W RMS 180W Max (Front) These work fine.
Speaker Wire
Phono connector L & R
Nikkai 6" 3-way (Not sure maybe 50W) RMS 170W Max (Rear)

The right rear speaker is connected to speaker wire then I twisted the speaker wire to the phono plug wire and then plugged into the right phono jack on the back of the Pioneer head unit. The same on the left speaker.

A rough sketch :)

Does the 106 actually have rear speakers or the actual wires for the rear?

If not, then you need to either wire them up your self to the HU or indeed us an AMP...
 
Phono is very low signal, its designed to be amplified you can't feed that directly to a speaker and expect to hear it.
Well you might just about if it was the only thing making any noise but would be incredibly low volume.

Check the manual, there will be as mentioned above 2 wires (on the iso connector) for rear right and 2 for rear left. They are signed (+/-) no major disater if wired up the wrong way round but will sound better and be more circuit friendly for the amp if wired correctly.
