jensen amp high level input

i just got a jensen amp, and it has a 6-pin connector on it for the high level input. Does anyone know what the pins corespond to?

looks like this:

| O [] O |
| [] O [] |

the top middle does not have a pin inside.

Also, are there advantages/disadvantages to using high input instead of low input?

anyone?

hi input is for mating a factory deck to a system ..... it just cuts the level a little before sending ther signal to the preamp

I have an aftermarket deck. Is it worth the trouble to route signal wires from the head unit, when i could just use the existing speaker wires instead?

read the thread 'high input low input' by Kenwoog guy. it might help...

be careful ...... the factory outputs at the speaker may have gone thru an amp and may not be compatible with a hi level input
