Need to know how to hook up a cd deck - Audio Players & Recorders

CD player to any audio in. Tape deck requires a dedicated tape in tape out connection found in older amps/receivers.

Turntable leads go to Phono.
Turntable ground lead (thin black wire) goes to screw terminal next to 'Phono'

CD phono cables go (unsurprisingly) to the CD

Cassette deck "Play Out" cables go to 'Tape Playback' sockets.
Cassette deck "Rec In" cables go to 'Tape Rec Out' sockets.

EQ Line Out cables go to amp's VCR/EQ Playback
EQ Line In cables go to amp's VCR/EQ Record Out

if this is a kenwood deck then by pressing the SRC will turn on the deck. tuner which would be radio and cd being cd player if the deck didn't turn on then it wouldn't show you any of that it would stay blank. for me to fully answer your help request I need to know the exact make and model of your deck. if there is no sound when you turn the deck on then try play with the volume as it may be turned down to 0 or 1 if there is still no sound then they didn't hook up your speakers to the deck. on the older kenwood decks there is a upside down triangle that is the SRC button on the newer decks it might be a rectangle button that says SRC. I hope i have answered your question, if so please vote and leave high marks. Thank you very much.

the parking brake wire just needs to go to a ground other than the ground for the deck and the orange reverse light wire you shouldn't have to worry about it if you turn on the deck and you still can't watch movies try hook it up to the illumination wire.

The yellow wire is the constant wire, you need to find the battery + wire which will be red and hooked that to your deck, the red wire is the main 12v wire and the yellow wire is there just to use a little bit of power to keep the memory i yur deck, i.e. the time, cd position stuff like that

always remember source, amp, then speakers. ex: cd to eq to amp to speakers and it goes: out from cd player into eq, out from eq into amp, out from amp into speakers . hope this makes it easier for you.

According to the manual at sony's web site, the sony cdx gt520 deck does indeed use RCA style hook up cables.

it will be hook p to the speaker in the truck you will not need to buy new one

Connect the EQ to the Sherwood as if it were a tape deck: EQ's outs connect to receiver's tape ins (play) and EQ's ins connect to receiver's tape outs (record).
Then you hook the tape deck up to the tape ins and outs on the EQ: Tape deck outs connect to EQ's tape ins (play) and tape deck ins connect to EQ's tape outs (record).
This will put the EQ in your receiver's tape loop.
The CD player should be connected to the receiver though the CD in's and out's (or if your Sherwood doesn't have a CD in/out, then use AUX or TAPE2).
To hear the EQed signal with all receiver sources (like the CD player) you'll need to engage the 'Tape Monitor' button or switch which will route the tape loop to the speakers.

The system remote control is usually a blue wire on your decks harness and it is for an amplifier for a sub or other speakers. It sends power to the subs amp when the deck is turned on. You may need to find the wires coming off the antenna and splice them into the red power switching wire 12v on you decks wire harness. Good luck
