I'm thinking about install a basslink into my RX400h. I wonder how do you run the wire from the battery to the basslink? I was looking for the firewall hole in the engine compartment but couldn't find anything. The battery on the RX400h is located on the passenger side and the fuse box is located on the driver side. Do I follow the wire cord on the fuse box or the battery side? Do I need to remove the rubber firewall in order to run the wire through it or just make a hole through the rubber? Once I got the wire through the firewall, where will it be located inside the vehicle? At the bottom of the carpet? Do I need to remove anything in order to see the wire from the firewall inside the car? Once I got the power line hooked up to the basslink, where do I tap it into? The speaker line or the level line of my rear speakers? I don't have to mess with my factory amp since the basslink already got a built in amp right? Thank you

 

No offense to you, but you need to take it to a shop if you're not sure about these things. It can be a very expensive lesson trying to do it yourself without someone there physically showing you how to do it.

To answer your questions, however, you want to make sure and run the power cable down the side closest to the battery. It doesn't matter where the fuses are - you need a fuse on the power wire of its own. You tap the speaker level - there is no line level if you're running a factory deck. You need to remove the trim and carpet to see the firewall - it's all hidden under there.

I'm still recommending you hit up a shop and see what they would charge you. It's just like installing an amp to them, so it shouldn't cost much more than that if at all.
