Adding amp, which LOC
I2007 IS350. I want to add an amplifier for a pair of subwoofers to the factory radio. Which line output convertors are recommended?

Ok so I think I’m going to order the PAC OEM line output converter. I’m assuming i can just tap into the rear speaker wires and run a short set of rca’s from that to the amp on the trunk. Is this the best way to set this up? Looking to run an Alpine type x sub I already have for now and then order a Sundown and build a box for it. So I want to make sure the signal is good from the start.

Search on here, If I remember correctly there was a thread with pics that helped me add subs with an amp. It was very informative.. I can’t remember exactly how I did mine, since it was so long ago. Sorry

Yeah I searched before posting. Not finding much that helps. Might just go with a cheapo convertor and see if it limits output or not and splice the rear speaker wires in the trunk.

Anyone familiar with this at all? I’ve got the line output convertor, rca’s, and signal wire for amp turn on but not sure if I need to tap into the wires behind the radio or possibly at a factory amplifier. If there is a factory amp, is it in the trunk? Anyone have a wire diagram or know the colors for the front speakers and which to tie in for amp turn on?

I used the Audiocontrol LC2i Line Out Converter. Do yourself a favor and tap into all wires needed (except low gauge power wire) in the trunk. The factory amp is under the plastic panel on the right side closest to the rear of the car. Grab a test light and, with the car completely off, check the wires going into the factory amp to get a constant power source. Then turn the radio on and find another wire that only comes on when the radio is on; that's your remote wire. Use the center speaker on the rear deck to get your sound signals (that's the factory sub). Below is a link to my original post asking for the same info. The wiring chart saved my life. This was not a particularly easy job. If you don't have experience with aftermarket stereo install, I highly recommend you leave it to the pros. Good luck! The whole thing took me 3-4 hours start to finish.

Alright well I made access to the factory amp. Does anyone know which set of wires is for the front door speakers? I believe it’s the harness that connects closest to the rear bumper but would like to confirm first as I’ll be wiring everything tomorrow.
