Question about Pioneer DEH-1500 CD Player

1 Answer

Sound quality When volume is at low levels sound is ok. As the volume increases, the voices become 'static' and 'distorted'. It can't be turned up loud enough to be heard over road noise. I have tried different speakers with the same result. I just bought this unit at an auction and the prior owner said it worked great. Also, I am unable to receive any AM stations.

What is the watts for the cd player?

It's published rating is a measly 13 watts per channel (four channels total). That is very low for a car head unit and isn't going to drive the typical speakers this would be used with to normalr volumes without distorting. Frankly, this entry-level unit is really designed for use with external front, rear and sub amps, which is why Eclipse designed it with three sets of pre-outs. On the positive side, the line voltage level resistance on those outputs is relatively low (55 ohms), so this unit will provide a good amount of gain into a given amp.

I have a Kicker 2500.1 monoblock amp. I am going to run 4 15 inch Kicker L5 subs to this one amp. What ohm subs do I need to purchase? Dual 2 ohm, or dual 4 ohm? Also, how would I wire these subs to pull a...

make sure that you get dual 2 ohm subs. to get a 1 ohm load, wire each sub in a series. that means the positive from one coil, connected to the negative of the opposite coil. then the other two leads will be your active speaker wires. that will give you a 4 ohm load for each sub. once all 4 are wired like this, you simply take all of the positive wires that you have left, and combine them at the amp. do the same with all of the negative wires. that will give you 1 ohm. just be extra careful to make sure every sub is wired exactly the same, otherwise your sound quality will be greatly reduced.
also, 2500 watts isnt as much power as these subs will take if wired together. it will still sound awesome, but I reccommend turning the level on your amp up just until you hear a bit of distortion, then back it off a hair. being slightly underpowered will cause you to have some distortion in your bass. playing distorted notes builds up alot of heat in the voice coils, and these subs are VERY sensitive to overheating.

Stereo cutting off when volume is over 29

Twenty nine sounds pretty loud to me. A shorted voice coil in any one of your speakers will drop its resistance value so if the amplifier thinks its feeding a short circuit, will "protect" itself by shutting off. Check wiring carefully and each speaker at a little lower volume for sounds of distortion ie: shorted voice coils...

Extreme distortion/static in music.

you might have blown your speakers. Thats what it sounds like, if it got loud with a lot of low-end then it got all staticy and distorted, you fried teh speakers.

Sub woofer volume adjustment

The gain dial is not a volume control. The gain dial is used to compensate the output level of your car radio head unit. all car stereo units output are not alike. If you set this gain level too high, it will cause major distortion (clipping) to the audio output of you speakers when cranked up. This excessive distortion WILL eventually, or even quickly damage or blow your speakers.

I personally blown speakers this way no not properly setting this. (lesson learned, I guess :| )

Volume fade

Check to be sure there are no speaker wires touching ground, and that the wires are connected in phase to the head unit.
Front Speakers 5 1/4" Doors Left Front (+) Green Left Front (-) Black/White Right Front (+) White/Red Right Front (-) Black/White Rear Speakers 6" x 9" Rear Deck Left Rear (+) Pink/Red Left Rear (-) Pink/Blue Right Rear (+) Pink/Light Blue Right Rear (-) Green/Red

The symptoms you are relaying definately sound like an internal amplifier problem. It is fading in and out for a reason - usually due to heat.

Have you had the radio bench tested (seperate from the car) to eliminate the car as being the culprit?

Since the radio was run with damaged speakers originally, the output or amplifier power supply on the amplifier may be bad.

As an alternative to repairing, I would suggest investing in a small 2 channel amplifier to power the speakers.

The radios claim 50W per channel, but in reality give 12-15W RMS power.

A dedicated amplifier with built in crossovers and gain adjustments will prolong the life of your speakers and add to the tonal qualities of your new speakers. Instead of turning up the volume on the head Unit, and sending out a distorted signal that will blow your speakers, an amplifier will give more CLEAN power to them, so it will be louder at a lower volume setting.

This will bypass the internal amplifier on the radio, and send a Low Level signal ONLY thru a set of RCA cables.

Good Luck!!

Sound problem

You have a shorted speaker or a speaker with a bad voice coil. This has been confirmed by the fact that the audio amplifier is shutting down (protection) but the unit stays powered on. The speakers will play for a few seconds or maybe even longer at lower volume, but any length or time or an increase in volume will immediateley shut off sound. This is due to the fact that a shorted speaker wire/connection will ground out or short to one another. If you have checked all connections behind the radio AND at the speakers and found no problems, then it is a voice coil on the speaker. A shorted voice coil will work until the speaker cone moves causing the short or until enough power passes through the voice coil's short to turn off the radio.
1. You can use a voltmeter set to check continuity to test for a speaker short. Disconnect all speakers from the radio and connect one side of your meter to ground and the other to the speaker lead. An audible "beep" will confirm a short.
2. The other method would be to disconnect all speakers and re-connect them one by one until the radio's sound output shuts off again. This will be your shorted speaker.
I hope this information was helpful.
