My Alpine car stereo model 9811 loses power then gains power when i drive. It keeps the presets, but its almost like someone is pulling out the hot wire from the back then re-attaching it. I've checked the hot wire and it seems fine. What should i do??

Make sure the yellow wire is connected to a source that still has voltage when the key is turned off. The yellow wire controls the memory of the deck.

Are you sure you are using the audio input wires and not the audio output wires on the back of this radio. there is also an input switch you need to set before the Ipod will work

try pacparts.com.

push and hold the menu and center button for ten seconds to REFRESH your ipod OR it 's the menu and play button.

No, its ok. Try to check the wire connection in the power supply. Check the fuse if the spring that pushes to contact is still working. The problem is on that area.

you probably have a bad output ic inside the deck.

this specific model alpine was famous for that pull the radio out and check the red yellow and black wire were they go into the harness on the back of the radio sometimes the pins in the harness loosen up

go to the alpine help forum and state your query theyl help you no bother, youl find this forum if you google apline car audio

The signal should go from the head unit to the amp to the subs. Someone must not have wired the subs correctly through the amp, or amp to the cd player..
