Stereo

So i've been having alot of problems with my stereo ever sinse i got my car. The kenwood kvt 514 in it came with the car when i bought it, so i dont know alot about its history. Anyways, it won't hold any memory. The only kind of memory it holds it written memory. As far as time and color schemes or audio settings, none of them will hold, they just reset as soon as i take power from it. I have it wired correctly, with the main power, ground and Mem wires all connected. I tried a jumper wire straight from the battery to the Mem wire and it still wont hold memory. However, if i just take the memory power wire off and try to turn it on, it just flashes a red light and wont turn on. so this tells me it's getting power from the mem wire and interpreting it as something, because it wont turn on without it, but it also wont hold memory with it after i turn it off with it even jumpered to the battery. Is this pretty much an indicator of a bad head unit?

The other main problem is that after extended driving the volume for all my speakers gets low and eventually there will be no sound, the only thing that will be playing is my sub, which has it's own amp. I have no Amps hooked up to the speakers however, they just go straight to the head unit. I also have a total of 8 speakers, with 4 pairs wired in series, as to not overload the head unit.

Since you jumped to a known source of 12 volts you can rule out the car's wiring.

Have you checked page 85 and 86 of the manual? It appears there are a lot of memory functions and lockouts in that unit. I'd also try to reinstall or update the firmware.

The volume dropping could be an ohms issue with the way the speakers are wired or once again related to buggy firmware.

Hopefully you can get it worked out as it looks like an incredible head unit.

Power takes two wires, jumpering to the battery for plus should make it solid, but maybe you have a bad ground?
