I don't recall the exact power wiring sizes, but the kit was rated as being designed for "dual amps" with "1400 Watts"...
Yup, I am just looking to tap into the rear speakers.
So when you are saying line-level outputs, you really just mean the rear speaker wires, right? Sorry if this sounds so dumb, but I just want to make sure.
It sounds like power won't be an issue for you. So long as your total peak wattage is below 1400 watts, it ought to be ok. Provided you've properly fused it all (fuse right by the battery, right?) then you shouldn't have a problem. If you start blowing the fuse(s) when the volume is cranked up, then you need to explore other options. Again, we're not talking about adding another huge sub amp...
No questions are dumb! Yes, by line-level outputs I'm talking about the speaker wires coming from the head unit. The wires carrying the signal & current that connect directly to the speaker. The wires that you've disconnected or cut to get access to the rear channels.
