Check the yellow wire connection on your wiring harness... This is the wire that provides continuous power even when the ignition is off. This is how the radio remembers presets/time and such. Every time you turn off the car, the radio "resets" because you dont have the yellow wire connected to an ALWAYS HOT wire.

If you cannot find a hot wire, then you can run a wire from the yellow on the back of your radio directly to the positive terminal on your battery. Dont worry, it doesnt draw enough power to run your battery down.

Most cars have a cigarette lighter or power port somewhere that is always hot. You could always run the yellow wire off of one of these.

Just find a way to get the yellow wire on a hot wire and your stereo will remember the presets.

I want to connect kenwood woofer sw-07 to pioneer amplifier vsx-d859tx. i am unable to connect please guide me.


Hello,

I don't recall correctly if your Pioneer has a sub out RCA connector, and if the Kenwood SW-07 has a low level input. So the usual way is to connect it using the speaker wires.
You connect either the FL or the FR to the sub and it should work.

Good luck

How do I adjust my subwoofer bass level for my kenwood kdc-138 car tereo


http://www.kenwoodusa.com/Support/Car_Entertainment_Owners_Manuals/ You can download the manual from Kenwoods site. While the unit is in Standby mode, press the B.Boost button for a second or two. You should now be in the Menu. Select SWPRE. Now chose SW from the (R*/SW) options. The output of your CD player is now a dedicated sub woofer output. I hope this is what you meant. There are many settings regarding the sub woofer and generally the sound in whole. Getting the manual is highly advisable. dreamsystems.

How do i set the rca settings for my kenwood kdc-217


Theres no way to change the rca settings. More than likely they put out 2 volts which is more common. Some newer more expensive models put out 4. What size remote wire you using? Try using a bigger (smaller #) gauge wire. That will give it a boost if your using the one that came with an amp kit. What kind of speakers? What kind of amp? If amp is mutli channel and only one sub then you will need to bridge the amp. Try different combos of + and - to see which gives the best. Also make sure everything is turned up on the amp and set to low pass frequency.

Connecting a car stereo to an amplifier


you have to connect your 4 speakers to 4 speakers output direct to your car stereo no need of amplifier to 4 speaker but speakers should be small not like a woofer, and you have to connect your sub woofer by using amplifier don't connect direct. connect the output of your car stereo (using 2 RCA) to the 2 RCA inputs of amplifier. If u connect your 4 speakers to your amplifier then your car stereo does not support Left Right channel.
You can also connect your laptop or iPod direct to your amplifier.
Good Luck
enjoy music

I have a kdc-mp435u and when i connect the subs woofers to it,it dissent put out enough out put Signal to it and when im driving some times it give signal the woofers cussing them to hit heartier. I check...


did you plug your rca signal wires into the subwoofer ouput rca's? if so you can control the level and frequency of the sub on the face in the audio menu. if this is not the issue try new rca cables. you can run them outside the car first just to test. another issue is make sure you have proper grounding on the head unit and amp. also if your rca cables acccidently touch power they can blow a fuse or trace inside the radio causing the rca's to lose ground (you will have low audio with lots of humming noise). you can check this by jumpering a small wire from the radio frame to the outer shield of the rca jack while it is all plugged in. if the sound gets louder and cleaner you can secure this wire in place by soldering it or fixing the circuit board itself.

Aux location


There is a RCA cable that comes off the back of the radio and also another cable for 3.5mm (mini-stereo jack) that also comes off the back of the radio. The RCA jacks can be used for "AUX" or "Sub-woofer" and the 3.5mm jack is just for "AUX". Your ipod can use the audio output jack or the headphone jack and plug that into the 3.5 mm jack on the back of the radio. You will need a "3.5mm male" to "3.5mm male" stereo cord that can be purchased at Radio Shack or Best Buy. Then you select "AUX" on the display with the source button to listen to it. You may need to go into the menu and activate the "AUX" input. Check your owners manual for details.

My kenwood kdc-mp235


I assume the amp is turning on (lighting up) No audio may be due to Burnt rca ground trace in your kenwood radio. If you have a ohm meter measure continuity from rca's ground terminal to radio chassis. Should be close to zero resistance. If there is no no continuity there are fusible traces on radios main board that burn open at times when to much current is flowing thru rca ground
Just a good possibility , haver seen this happedmany times.
If you need service manual let me know kstahl65@att.net
