I finished wiring my D3 yesterday without using my stock amp.

I was thinkin about this but not sure if it would work.

On the 2001 IS300 wire diagrams it says the car has 2 rear woofers. I was thinking about wiring RCA inputs to the woofer wires and running that to my Sub output RCAs on my D3.

Will it work? and is it even worth my time?

I don't think it would change anything. They're not really rear woofers, they're just rear speakers, you wouldn't get better bass or anything if you did what you mentioned

You can add RCA's to the stock amp, you need to know how to solder in SMALL Ass places to small ass pins. If you don't you can heat up the board and fry the amp. I have seen a few of these now..

Ive modded over 20 stock amps now.

This should work, but I'm sure pre-wired woofer wires don't have as good insulation as off the shelf RCA cables, which might make them more prone to noise. They are twisted together though, so that might help with the noise. Give it a shot, you don't have much to lose except maybe 4 RCA connectors :)

Personally though, I'd just run my own RCA cables, it's not that hard and you're guaranteed more protection against noise.

This will only work if the rear woofers have a seperate amp. If your talking about the two ohm speakers in the rear deck, it won't work.

The RCA outs are preamplified signal on the headunit. This means they only carry a low-level audio signal to the amplifier via the RCA. The amplifier takes this audio signal and amplifies it into a high-level signal, which is what speakers play.

There are no woofers in the car.

The rear speakers are just 2 speakers stacked up on each other. Don't waste your time.

BUT if you replaced the headunit without using the metra harness. REPLACE THEM.

about the soldering of the rca to stock amp

You can add RCA's to the stock amp, you need to know how to solder in SMALL Ass places to small ass pins. If you don't you can heat up the board and fry the amp. I have seen a few of these now..
