If your radio and phone are synced up together, it probably muted the radio when the call came in then didn't un-mute. I'd try to reset the radio (disconnect the power for maybe 10 minutes) and try it then.

Car Audio - mixed ohm speakes - best setup


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

http://www.fixya.com/Uploads/images/94A2E8C.jpg

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.

Subs made funny noise than lost complete power to the amp?


Could be many problems too hard to explain unless you are there. Here are somethings that can help you:
1. settings need to be tweaked up or down on amp.
2. check fuses if amp has no power at all. sometimes power protect comes on and you only need to reset by turning on and off car or shuting down radio and restarting.
3.If this is a new set up then you have a bad amp/speaker combo

I need a wiring diagram for installing 2 LT980-2


do you need help just for the power or for the audio or both?

power it is simple
positive goes to the battery but with a fuse in the middle
negative goes to a metal ground point on the car (but not battery)
remote goes to the radio with should have a blue and white cable if radio does not have remote line then use the acc wire from radio

for sound
your amp does two speakers and im guessing you want the back ones amplified
so cut the 4 wires that come from the radio and goes to the back speakers 2 positive and two negative
and connect this to the input the phono terminals on the back (unless your radio has phono terminals for audio out on the back side

then take the output from the amp and run it to the speakers one positive and negative to each speaker

i cant seem to find a wiring diagram for that amplifier but i can give you a more genral diagram

Trouble connecting marine amp to stereo


Hello lizskates814,

You can use either the high level (speaker) or the low-level (RCA's) inputs to the amp, but not both. Choose whichever one sounds the best or is more convenient to install and leave the other disconnected.

Hope this helps.

I have my amp hooked up but it isnt getting any power can you tell me if i have a bad amp or if i need the speakers and sound for it to come on?


With all amplifiers for a car, you must have the main power connections B+ and ground connected, and then you must also have the remote turn on connected as well. This is the way the amp turns on. It comes from the radio and is usually the blue wire from the harness off the back of the radio. When the radio is turned on, the blue wire gets 12 volts sent to it so it can turn on an external device like an amplifier or the power antenna. Make sure you have this connected to the amp and that the radio is turned on. Then check the voltages at the power terminal of the amplifer. You will have the ground, the main B+ of 12 volts, and then the turn on voltage of 12 volts. If you have all of these, then you need to troubleshoot it more. It will turn on without the speakers connected, but I am not sure why you would want to connect it without the speakers. It will also turn on without the RCA cables connected for the audio input as well. But just to turn on the amplifier, all you need is those three things i mentioned. Let me know if you require any further help.

Pioneer gm-5000t amp


If the amplifier is powering, but no sound, try disconnecting the speaker outputs from the amplifier and connecting a test speaker to the output channel. If you get sound, then one of the speakers in the car may be bad or shorted out. That can be confirmed with a voltmeter. If still no sound, then you need to check the input to the amplifier. Disconnecting the RCA cable from the input and testing that with an amplified speaker like you can get from Radio Shack will allow you to make sure that the amp is getting signal from your radio.

Amp in protection mode


Disconnect all speaker wires and signal cables from the amp. If it powers up normally (doesn't go into protection), the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
