Prevent HU turn off during ignition

If you want to test to see if this is even possible to have the radio stay on while cranking(don't know why 5-8 seconds though) then what you can do is to try this: pull your radio out, run a FUSED wire from the battery to both the radio's constant and switched, then try and start your car. If your radio stays on then you can run a constant and a switched from your ign harness. If it turns off while cranking then it won't stay on. Starters just draw alot of power and the voltage drops below the minimum voltage for the radio to stay on.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

Hello there is a reason why your stereo is turning off when you crank the car. it is connected to the accessory lead on the ignition switch. You have 4 positions off-acc-ign-start. In order to allow all the current to flow to the start systems that require a lot of energy for the start i.e. starter and it is a bigger priority than you music, all your accessories are turned off while you are cranking the car i.e. stereo, ac, fan and some others. This is done simply by disconnecting a switch inside ignition lock during start position and connecting it again when you return to ign or acc position. It is a very good safety feature which insures good starts and safety of your electrical systems.
