Pioneer DEH-X6500BT amp & speaker problems


Depending on the car and your setup sounds like the amplifier is not wired properly or an issue with adjustments on your deck itself. More info on your sound setup would be helpful.

I have a ADF-242 that is having sound output problems


If the car was running when testing sub and heard noise this could be engine noise and an inline filter would cure that problem and also have a good ground no more than 15 inches away from the amp.And good metal contact for ground.

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.

Hooked up the amp, lights up, fans kick on and run fine, speakers hooked up proper, no sound? hooked up speakers to another amp and they work fine. Fuses are all good too. Thoughts?


could be bad rca cables or no output from the radio rca outputs. the sub control may be turned off on the radio (ive seen that alot at my work). if all that is fine, the amplifier may be bad. the rca cables may be plugged into the "out" section of the amp. gotta look at all the small obvious things first. good luck.

Subwoofers dont bump


No such thing as a typical sub system. Be more specific? If the subs are moving well and just not basing you will need to check 2 things first. Try the polatity of the speakers (reverse one) they may be out of phase and will cause the bass to cancel eachother. Another cause is the box may the incorrect size for the speakers and will not give you the correct sound the speakers are capable of. If neither of those work check your amp settings and make sure its set on sub/low frequency.

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.

Air conditioning condensation and speakers


Check for audio from the radio. Hook up some test speakers and make sure the radio is working. If not then your last stage audio amplifier might be defective. also test you after-market amp by injecting audio into in and see if it is still functioning. If the radio is not working and the after-market amp is then the radio is the problem and its internal amplifier will have to be replaced. If the radio works and the after-market amp does not then the after-market amp will have to be repaired. I would suggest getting this testing done by a professional auto-sound shop, to make sure the proper testing is done.

I hope this helps,

Amp wont work jxp340


hi if you got a voltmeter TEST IT ALL ON A LOW LEVEL OF VOLUME!! check the outlets of the amp if there is a signal at all... no? - the amp isnt hooked properly! yes? - check if the volt level on the outlets is higher then the level on the inlets of the amp (the amp is amplifying) no? - the amp isnt hooked properly! or its bad... yes? - connect a speaker to see if its working wont put out a lousy spark? check your system, the problem if probably there... check all the connections, fuses, wires begin from battery and go FWD antill the next device isnt working good luck
