I have a couple of these 12 volt led strips left over from another project .
each led has a 560 ohm resistor wondering can I switch the value of the resistor to make them brighter?
And if so what value resistor should I use ?

The resistor was likely chosen to give the greatest brightness that the LED could provide with consideration for the life of the LED. Greater current from a lower value resistor will likely reduce the life of the LED.
Was a datasheet included with the LEDs?

Not worth the hassle, and replacing resistors on a thin PCB or foil base requires skill and experience.
Even if you can, the LED may have brightness and life issues.
Some are static sensitive, also to leakage from soldering irons.
You will not achieve much.
They are very cheap, 3 cents to 5 cents each...in packets of 1000.
And there are now LEDs with integral resistor for 12V use.
There are also SMD for 22V constant current used in lighting.
Shop around.
These you can use with a 12V supply for lights that you may need to have constantly on, such as those in passages, or on the light switch boards, very useful for aged people.
Heat sink may be needed.

12V LEDS for 0.60$ for 20 pieces... https://lcsc.com/product-detail/Light-Emitting-Diodes-LED_XINGLIGHT-XL-3528UOC_C2843804.html
I think they're red though.

Ok I found some different leds that will work super bright .
Now to my next question might be a weird question but here it goes .
I cut out the DD logo as seen in the pic . I have red leds mounted behind the panel to light up at night . But you can see the black carpet on the speaker box as the leds illuminate it . The black carpet doesn’t look the greatest .
Any suggestions as to what color to put behind the letters to make it look better ? I also want it to look good during the day when the lights aren’t on . Maybe a darker black or any suggestions. As you can see I used white leds at first same issue with the red leds you can see in the 2nd pic the background doesn’t look the greatest

Put white opaque plastic on the box directly behind the cutout. Put white translucent plastic behind the cutout to diffuse the light.
