Kenwood KTS-300MR Power problem

I have a Kenwood KTS-300MR on my boat, its is a little under 2 years old. The unit will not power on. I have checked the fuses and wiring on the unit and everything is fine going into the unit but it will not power on. I have pressed the reset button with no success either. Does anyone have any suggestions or does the unit just need to be replaced?

you need to firstly trace the speaker wires to the unit to make sure there connected first. if they are then its a job for a car audio expert ( if there is such a thing) if the unit is connected to correctly to the speakers then there is an internal fault ..

Here's a link to manual and wiring on page 30 on the PDF file.
Yellow is constant power from battery, for memory etc. Red should be to switched source.If need be, you can connect both to battery, but remember, you'll have constant power draw on battery when stereo left on but switch turned off, and will draw battery down, if you forget to shut it off, and leave the boat. Speaker negatives to black should work but I would advise hooking my 2 right and 2 left + speaker wires from stereo together, then to one of the speaker positives,right or left for better sound. Fronts will usually supply higher ( high and mid range), and rears will supply lower sounds (woofer) Joining them together will give better sound usually, when only using 2 speakers, on a 4 speaker stereo. You may want to test with them joined and not, to see what sound you like better.

When you connect multiple speakers to one channel it drops the impedance. A radio is designed to play at 4 ohms which would generally be one speaker. When you connect two speakers to one channel it drops to a 2 ohm load which can be fatal for a radio but not always

CALL on display


Hello plainolelow,

"CALL" is displayed whenever a telephone call is received.

This is controlled by the brown wire from the wiring harness, and is activated when your telephone system or bluetooth device adapter detects an incoming ring. Activation is a "ground" on the lead. If you do not have a telephone or bluetooth adapter attached, the wire is probably coming into contact with some other wire or metal that is causing it to be momentarily grounded.

Hope this helps.

Setting up an account


In order to solve this problem, personally view the ID number of the radio in the car just to be sure, and call XM's 800 number once again.

Explain to them that even though this radio is on another account, it is permanately installed in your vehicle. Explain that the information they have on file must be the old owner of the vehicle and ask to see if the account is current or if it is old and unused. Tell them that any balance on the account is not your problem and that the radio came with your vehicle from a dealer. If they tell you the account is very unused and very old then ask them to please apply this radio ID to your new account that you need to create with them right then.

This kind of mismanagement of new customers is what big companies need to watch out for and stop doing. They need to recognize that a new owner of a car radio is not working for their accounting department and is not responsible for the former car owners satellite radio debt.

No Sound - boat stereo


Assuming that the four speakers are connected to the amplifier, then the amp is the most likely problem component. Does the amplifier show a power light when the system is turned on? Note that there is probably another fuse in the amplifier power wire, near the battery.
