Question about Pioneer NEW GMD8601 1600W CAR AUDIO MONO AMPLIFIER AMP WITH BASS

Open Question

My Pioneer GM-D8601 800w mono sub has a constant red light and doesnt work. Its connected to the same power block as the other pioneer amp which is a 4 channel and works great.

I got the amp used so maybe its defective? because the other amp connected to the same power block and same ground block works great with a constant blue light. I even reqired the sub from 1ohm to 4 and still stays red

SOURCE: i have a pioneer gm-x404

The wiring is fairly straight forward. Along the top row of the ten pin plug =
(Left to Right)

Front Left positive,

Front left Negative,

Control wire from your stereo head unit should be thin blue wire sometimes listed as Remote Wire this switches your amp on and off via your head unit so you don't run your battery flat,

Front Right Negative,

Front Right Positive.

Bottom Row=(Left to Right)

Left Back Positive,

Left Back Negative

Centre Nothing

Right Back Negative

Right Back Positive

These are all inputs from your head unit.

To bridge from 4 channel to 2 you connect

one left speaker to Ch B Left Positive and Ch A Left Negative

one Right speaker to Ch B Right Negative and Ch A Right Positive

Ten Switching the Input Select switch to 2CH

Alternatively if your unit has RCA's on the back of the Head unit you can use them to run your subs.
Hope that helps.

SOURCE: Red light showing up on amp ( pioneer 800 watt GM 7200 amp )

it could be the amp it could be the way you've installed and if you have a sub in an enclosure the wires could be touching the postive and negetive speaker wires what ever the problem is the amp is in protection mode i hope this helps hope its not the amp i hope its just the wiring

you Amp is overloading and going into protection mode. if it cuts out with the wire u were using first then their would be no need to upgrade the size of ur wire cause that would only be, doubling or trippling the power u are getting threw those wire now. bottom line the 2 subs u are using are obviously to much for the amp. try dropping the OHM's by connection the subs together and runnig just a single positive and negative to the amp! or just get a better amp

Sudden loss of power


Are you sure the battery is being drained during this process? That would be a major draw from something, but then you said "...suddenly full power again,". It sounds more like a connection or a terminal working loose at times, not able to pass normal voltage. You sure need a voltmeter, my friend.

I think I would want to have that new alternator tested again, just to make sure it is not defective. A lot of aftermarket parts are turning up like that. Did you replace the alternator and battery because this condition was present? Do you know your battery cables and ground points are all good and secure, and corrosion free? You might want to double check all the grounds you can find- the battery negative cable, the engine to body strap, or cable, maybe an engine and computer harness ground point-look around the top of the engine for a ground wire coming out of the engine wire harness and going to ground at a nearby bolt. Also check all alternator connections.

If you have to keep looking, look at the power side of the power distribution scheme. From the battery, power goes to the Power Distribution Center, maybe called a junction box or junction block...it is where the fuse and relay block under the hood receives power, both from the battery and the tie-in from the alternator, and then distributes it to the major circuits for the car. With all your symptoms, it sounds like the problem is not far from the battery in the power distribution. Sayeth Dr. monte. Good luck.

I have 2 pioneer 6x9 400w, pioneer GM 6500f 760w amp and a kenwood KFC W1012 sub, how d i get the best sound from these?


pioneer gm 6500 is a 4 ch amp rated at 60w-4 way to small of an amp to run your sub. UNDER-POWERING your sub is more likely to damage spkr than over-powering. my advice,get mono-block to run sub

Amp constantly blows fuses as soon as power wire is connected. anyway to fix?


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty .
.A thumbs up would be greatly appreciated if this answer is helpful to you

Whats the red wire is it constant power? When I ground it can I put it to the radio ground?


You should have a yellow wire that is constant, and the red is for the ignition. It's what signals the EQ to turn on. You can hook the ground up to the radio ground. It's not advisable to do it that way, but you can. The reason why it's not a good idea is because you should use a bigger wire when you connect two smaller wires. Most wires behind the radio are about 16 gauge. Using bigger wire number sizes for an amp as an example, you could use a four gauge wire to a distribution block. From there you would use two eight gauge wires to go directly to the amps. This helps electricity travel the path of least resistance. It does not matter so much on smaller wires.

Hi, you can split the preamp RCAs with Ys available everywhere. The amp input impedance shouldn't cause much load on the head unit. Let us know if you have more questions, and thanks for using FixYa.

I have a Pioneer GM X862 car amp, with a constant red light on it. Also, it is supplying the subs with power, they are lightly vibrating but its not pushing like it should. No bass.


Make sure your power line comes directly from the battery and that iyt has no abrasions or cuts in it. Check your ground and make sure that it has a good connection to the vehicle chasis. Ensure that the remote line is connected properly to the remote lead from your head unit/receiver.

Common mistakes in this area are using the remote turn on lead as a power lead. It does not have near enough power to drive the amp so you will only get a slight trickle of power.

Good luck!

I have a pioneer gm-d8400m the amp isnt working


flashing light could mean a few different things. 1- constant power may not be there. check with a test light or multimeter. should read around 12 volts. it would be a good idea to check all the power and ground leads. make sure u have a good ground. 2- bad sub. im assuming sub since its a monoblock amp. you can meter the subs. make sure the total ohm load is no less than 2 ohms. any lower the amp will go into protect mode. 3- bad amp. power supply may be bad. the newer pioneer amps are full of protection circuits. ive been a professional installer for a shop about 8 years and we sell pioneer. hope it helps.

Power led flashes and amp doesnt work at all


Hello hexi_86, The amp is going into protection mode. If it goes into protection immediately upon power up, either the amp itself is defective or it is getting too high or too low of a voltage or current, or the outputs are shorted. 1) Make sure that the battery voltage, as measured at the amplifier?s +12 volt and ground terminals, is 11 volts or more (your alternator voltage is typically about 13.8 volts). So if you have 11 or less at the amp terminals, your wiring is too small or defective. 2) Check all +12 volt and ground connections. 3) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current. Check by removing the speaker wires one at a time to locate a shorted wire or defective speaker. 4) Check all speaker connections. 5) Remove RCA inputs and see if the amp powers up properly. A shorted or grounded RCA cable can cause the amp to go into protection. If all these check out, the amp itself is probably shorted internally, most likely the output MOSFET's. In this case it needs professional repair or replacement. Hope this helps.
