    Hi, im hooking it up in my room, ok tell me if this would work i got a 24volt plug that goes into the wall the amp only needs 12volts so what if i get 2 amps which would equal 24volts could i just split the plug that goes into the wall into 2 hookups for both amps with electrical tape and like twist them together or wat ever and if not could u let me know other wise like send me a simple drawing or diagram on how to split the 24volt plug into 2 hookups that would be awsome my email is

    Hi, so where could i get a small baterie charger? ad would i have to use jus the charger or would i have to use baterys to?

  • gignac Mar 07, 2008

    so where do u think i could get one? (charger)

  • gignac Mar 08, 2008

    so just to be sure i ask for a 12volt battery charger? i herd it might need a lil more like 13volt or 14volt cuz the positive has to atach to the REM too so it needs a lil more voltage for current is this true? if not let me know exactly wat voltage charger to ask for thanks

You could get one at walmart, radio shack, or any automotive store

You could use either or both. I would use the charger in the house. The only thing is that if you have a big amp, the charger may not work at high volumes because the bass may draw too much power. The best way it will work is to hook them both together but I dont recommend you charging a batt in the house.

No, 24 volts will burn up your amps. If you can get a small battery charger, you can use that to power your amp. Hook it up the same way I told you with a car batt.

First of all, is this going into a car? If you are just hooking this up for whatever, the positive from the batt goes to the (+) positive on the amp. The negative from the batt goes to the (-) negative on the amp. The (rem) remote wire will also go to the (+) positive on the batt. If its not in a car, its only going to work for a short time until the batt dies. If it is going into a car, post it.

    I'm sorry, I forgot the red and white wires. Plug the red and white into the input of the amp and the other end into the output of the receiver. Be careful though. The red and white plugs are low level inputs and if turn the receiver up too high, it may damage your amp.

    ask for a regular 12 volt battery charger. Most chargers go up to 13.8 or 14 volts. Ask for a simple car battery charger.

What is the REM (remote I assume). The second hot wire other than the red is usually yellow. Is your REM wire yellow. Also, don't forget to put a fuse in the "positive" side of the circuit. Keever

I have a pioneergm-d8500m amp and it stopped working and the green led just flashes.. i bought a new amp to replace it and it just does the same thing.. what is going on to cause this

crossed speaker wires or loose strands creating a short circuit, improper speaker ohmage or a blown speaker.

verify that you dont have any positive strands coming in contact with negative strands/terminals, the amp case, the speaker frame, or any metal part of the car chassis.

verify that you only have a 2 ohm load connected to the amp. most car speakers are 4 ohm (siginfied by the greek letter "omega" on the back of the spoeaker magnet, or in the speaker specifications), but some are 2 ohm and/or 2 ohm x2 voice coils per speaker. 2x2 ohm coils/speakers would produce a 1 ohm load, which would cause the amp to overload, and go into "protect" mode. to achieve a safe load, you need to use 1x4 ohm speaker, 2x4 ohm speakers or a dual voice coil speaker with 4 ohms per coil x2 voice coils, wired in parallel.

you can also achieve 2 ohms with 2 speakers with 2x2 ohm voice coils apiece (that is, 2 speakers, each with 2 ohm voice coils apiece, 2 speakers with 4 voice coils altogether of 2 ohms apiece) by wiring the two coils per speaker in SERIES, and then wiring the two speakers circuits in PARALLEL. wiring the coils in series means connecting the positive lead of one coil to the amp positive, then connecting the same coils negative to the positive of the second coil, and finally connecting the negative from the second coil back to the amp negative terminal. if you wire both dual voice coil speakers in series, and then connect both series circuits back to the amps positive/engative, than you have the coils in series, and the speakers in parallel- achieving an overall 2 ohm load from 4 total voice coils between 2 speakers.

if you need a better explaination, comment back with your exact speaker combination (brand and model # of speakers + number of speakers), and i will provide a more specific description with your exact speaker set-up in mind.

Have hooked up al conections properly acording to diagams but amp will not pwer up. tested wire conections and i am getting juice to the amp but still no responce fuse are good amp is brand new out the box...

If this is new out of box make sure you have 12volts to the amp turn on wire. You should have constant 12volt + to the battery terminal 12volt- to the ground and 12volt + from the head unit (radio) to the amp The turn on wire on most car stereos is a thin blue wire. run this wire to the amp's terminal and when you turn on the radio the amp should turn on.

My amp turns on but stay in protect mode

check your wiring, is it properly grounded? is your remote positive wired to your ignition's positive line?

Car Audio - mixed ohm speakes - best setup

Here is the link how the speakers are suppose to be connected.

You notice how they hook it up the left connections are your full range or hi frequency speakers and the switch is on for HPF (High pass Filter meaning only high frequency is being passed thru)

The right connections are connected to subs and the switch is on for LPF (Low pass Filter meaning only low frequency is being passed thru)

If you turn off these switches to off the its FULL RANGE all frequencies will pass thru.

The single output of the radio is probably for a subwoofer output but since your using the amp to power speakers too Its useless because your sending only low frequencies to the amp which will make any speakers connected to the amp sound horrible due too all the highs and mids will be filtered out.

STEP 1. 2 4ohm speakers depending where you put them Front or back. Hook these speakers up to the Radio's speaker wires coming out of the radio harness. You can also call them Hi level output wires FR & FL wires if positioning them in the Front. Hook them to the RL or RR if positioning them in the Back. What ever wires you dont use tape them SEPARATELY . DO NOT TAPE THEM TOGETHER and cause them to touch each other it will short out the radio and you will hear no sound.

STEP 2. Ok get 4 same length speaker wires and cut them long enough to go too the amp. Now these speaker wires will only send the FULL RANGE frequency signals to your amp. So note with a paper and pen how your connecting each speaker wire. I would tape one wire with black tape to remember this is the FR right, 2 tape FR left, 3 tape BK right, 4 tape Bk left. And I would make the copper thread of the wire positive and silver thread of the wire negative (very important so that your in phase and it will sound awesome) mixing up the positive and negatives will give you a tinney sound and it horrible to hear .

STEP 3 connect these 4 speaker wires to the High level out speaker wires coming out of the radio. The wires that are already connected to the 2 4ohm speakers go ahead and splice into them and the ones you didnt use connect to the remaining 2/4 speakers. REMEMBER OR NOTE THE CONNECTIONS cause you have to connect the right sequence and right polarity + & - to the HI Level input of the AMP. You will not use any RCA'S from the radio to the amp anymore. Since your radio dont have any Front & Rear output coming from the back of the radio. (YOU CANNOT USE BOTH RCA INPUT & HI LEVEL INPUT OF THE AMP ITS 1 or the other OR YOU WILL BURN OUT THE AMP AND DAMAGE THE RADIO)

STEP 4. Now connect your 2 6ohm speakers of your front left and back left together in parallel and your 2 6ohm speakers of your front right and back right together in parallel. Look at the diagram hook it on the left connections as in the picture of the front left speaker(but your connecting two 6ohms valued at 3ohms when in parallel and the amp can handle 2ohms so its safe) Do the same connection for your two right speakers as shown in the diagram of the Front right speaker. SWITCH THE HPF to OFF so that you get full range out of your speakers. Mid range is 70% of your music if you turn it ON you are only getting the high frequencies and it will sound awful.

STEP 5. This is the final connection Your 6 ohm sub is very bad for this amp. For example if you bridge it off of the last two channels the amp may double the power. If each channel is 100 watts and you connect the positive to one channels positive and connect the negative to the others channel negative(presuming its bridgeable) On a regular 4ohm sub it will be getting 200 Watts of power which is an average thump. Now you put a 6 ohm sub it will be weak and it will be getting around 130Watts. To make it worse if this 4 Channel amp is not bridgeable you can only connect it to 1 channel and the output will be around 70 WATTS causing distortion due to lack of power. If you still connect the sub be sure the switch is ON.

Good luck cause this the best connection you can do anything different and I'm sorry it will sound even worse. I am a master installer and have done this for 12 yrs. The higher the ohms the worse the sound gets cause less power. Thats why car speakers are 4ohms and home speakers are 6 ohms or higher cause they have a bigger amplifier to power and 120volts AC current. A car only has a 12Volt DC current powering the amp.

My amp wont even turn on or red light or nothing so what do i do

check ground cable, check fuse on amp, and check the fuse under the hood, on the positive cable should be about 12' from the battery, if all is well and theres no light, check the blue wire coming from your deck use a tester,if bad you can run one of your fuse box ,place a 12volt switch and hook it to the amp you should be good to go

run a wire from the battery to the place u are putting the amp. place a fuse in that wire no more than 10 inches away from the positive batt terminal. find a bolt near the amp and see if it is grounded. if so connect a wire from the bolt to your neg terminal on the amp. then run a remote wire and your rca from your radio to the amp. then connect a set of speaker wire from the amp to the subs or speakers

ok well this is easily checked with a ohm meter see what the resistance is then if ok you might have a problem with your amp wire the speakers direct to the amp do not use ground on the car to negative on the speaker the amp is making its own ground called a floating ground do not hook the speakers together cause then you might put the in series or in parallel this is dangerous to your amp will make it work harder. so put the positive of the speaker to the positive on the amp and negative to negative same for the other speaker
