Hi my Honda CR-V 97 not enough power to hold memory and clock wont hold time ether and resets ever time I restart the car yours very confused

The stereo should have two 12v wires; one is switched power and the other is always on 12v power.

The memory needs always on power since there is no internal battery to remember presets.

My 01 civic wont keep memory everytime i turn it off it resets the clock and stereo

It sounds like the keep alive wire has either become disconnected or it was never hooked up. In most cases it is a yellow cable on aftermarket car stereos

I just put a new stereo in my truck but wont keep memory?

you didn hook up the hot at all times wire, or memory wire, its usually yellow on aftermarket stereos and goes to the batt. a way to find that wire is to pull the stereo, leave everything off, and check wires for voltage. once you find one with volts when key is off, just hook the wire up

How can I hook up the speakers on my car to my stereo? Got it workin just don't know what I need to hook up the speakers?:

Most modern car stereos have 4 channels. Each channel has a pair of wires, one a solid color and one the same color with a black stripe. The solid color is positive and the black stripe is negative. The channels will be color coded white for left front, grey for right front, green for left rear and purple/violet for right rear. So you simply hook up the positive and negative wires from each speaker to its corresponding channel based on the speakers position in the car.

Cannot get the memory to work when setting channels for the stereo. And the clock always resets to 12:00 everytime I crank the vehicle.

Very simple solution. What you need to do is remove the unit and swap your RED (ignition) wire with your YELLOW (constant or battery) wire.
there is not much more to it than that. if you provide me with your vehicals details i can give you a complete wiring diagram.
hope i helped and please dont forget to rate my solution

Either you blew the memory fuse or didn't connect the radio to the proper wire. Check fuses inside and under the hood.

The memory wire to the radio needs 12v all the time. If it's not connected or no power at the lead the radio will reset every time you turn off the car.

I have to reset my channels on my sendai car stereo every time i turn engine off

I would suspect that the radio is not installed correctly. There should be 12V present on one wire for retaining memory. There is a capacitor inside the radio that will retain memory for a short time (less than 5 minutes), but you should not have to reset the system after each start. If the wiring is correct, then the internal memory system may be defective and require replacement.
