Question about Pioneer DEH-1800 CD Player

1 Answer

RCA Problem Hi...I recently purchased the DEH-1800 model CD player and installed it without a problem. When I plugged my existing subwoofer in(via RCA cables) to the Preamp Output, nothing came out of the sub except very little vibration of the cone(no audible noise). I then reinstalled my previous Line Output Converter to check to see if the sub or amp still worked, and the sub played fine. So, what I think is going on is that the RCA Preamp is putting out a signal that has no low frequency audio in it because it has some sort of a passive crossover in it. Is there any way to make my sub able to be played through the RCA Preamp of the DEH-1800 or should I just use my aftermarket LOC? Thanks!

    Hmm, ok. Thanks for your help! So the RCA output is only for higher frequency(mids, tweeters, etc.)? Thanks again! :)

    My DEH-1800 when plugged into a sub it"motorboats/distorts or cuts out all together when both RCA's are plugged in .I have an older Pioneer that has RCA outs and it works fine with the Sub.

You need an active subwoofer input in your amplifier.Which amplifier you are using? Only latest pioneer amplifiers has active sub input and sub output which can be connected to subwoofer.If you dont have active input then you will have to connect it the way you did in old player.

Hi. A model number and the speaker models will help.

Sounds like you need to go from the green 3.5 mm jack to the two phone sockets marked "input" on the sub. White left, Red right.

"output" RCA sockets look to go to your speakers but without model numbers I can't see if they'd need to be powered or not.

Can the pioneer DEH- 1800 play mp3

No, I'm afraid not. Usually you can tell if a pioneer will play mp3 cds, because there should be "mp" in the model number. Such as "deh-1800mp".

Not satisfy with the sound of my system

This Unit has got a 4x60w amp built in.

On it's own the subwoofer will not work, you need to buy a Monoblock amplifier, a wiring kit and a set of RCA leads to run it.

The RCA leads plug into the SUB output RCA sockets on the back of the headunit.

The OEM speakers in your car will not be of great quality, so it would be wise to change them. If you do, you need to buy speakers that have a rating of no less than 90watts, any thing less and they will sound distorted.

Any car audio shop will be able to help you select the right size and rating to suit your car. They may even fit it all for a charge.

Hope this helps

Wiring my tuner-DEH-1800 to Amp GM-5300-T into my 4 speaker system.


In most head units as in your case the Pioneer DEH-1800, there would be 2 RCA female jacks at the rear of the unit. These are your OUTPUTs.

While in most amps including your GM-5300-T, there would similar RCA jacks which would be your INPUTs.

You need to connect the output to the input using an audio cable terminated at both ends with RCA plugs. Further you need to connect the remote trigger on from the head unit to the remote/external amp to switch it on.

A more comprehensive connection diagram is available at page 6 of the GM-5300T Manual which may be downloaded from here.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
