Hey guys, i was wondering if someone can help me out. I'm trying to install my mono amp and sub into my 03 ford escape. I got the power wire hooked up and routed, and i already have a grounding spot. However, the factory HU doesnt have RCA =(. Can anyone explain specifically to me how to install my amp using speaker level input?(yes, my amp has the option). What wire do i tap into and such? Also, if anyone can tell me what wire to connect my remote turn on to you would be helping me a lot.

Thanks ahead of time!

Edit: also, what can i use to hold down my sub in the trunk? Thanks!

I was hoping someone might be able to shed some light on this gentlemans question as I'm in the same boat. My plan was to install my LOC into the front or rear channels up by the HU but I was wondering if this would throw off the factory ohm load and damage something? Also there appears to be extra speaker wires coming out of the factory harness that I can't account for. Are there unused speaker leads there that I can use? Or are all the wires in a factory harness truly used. Thanks in advance if you can help us

I attempted to find a wiring diagram for the factory harness but was only able to locate one for the 2005+ on the boards here.

A factory radio never (or almost never) has RCA.

Tap into the front speakers, they are often less contoured by the head unit.

Will do, I just wasn't sure if it would cause an ohm issue adding something to one of those lines. Seems this is common practice though.

If tapping just for an LOC or something, you aren't introducing a change in ohms that the head unit or speaker will react to. Certainly if powering two sets of speakers via a splice, that could be trouble.
