Hello,
For the longest time I have had a good amp lying around that I used to use in a subwoofer system in a Jeep Grand Cherokee we used to have. Recently I have been getting the car audio itch and decided I wanted to install it in our 09 Legacy. This Legacy DOES have the HK system in it. I believe I have gotten most of what I need to do the install for it, but I do have a few questions.
1 - Any "gotchas" in running the power wire from battery to trunk? Any advice to make that process easier?
2 - What is a good spot to ground in the trunk?
3 - I am using Line Output Converters to get music signal to the amp. I am not replacing the head unit or speakers or anything in the car. What is the least painful speaker to tap in the car for signal? I know there is a subwoofer in the back already, but it looks like it's mounted up side down, and the wire to it is obscured, I am guessing under the rear deck panel behind the seats? I looked at how this comes off and it looks to be fairly involved. I was thinking maybe one of the speakers in the back door, but that panel also looks to be a pit of a pain to get off. The door handle (opener) looks to be the worst part with cables and such.. I can just see me never getting that back on right... Also, I know the HK amp is under the front passenger seat (I think). I believe I can tap off the subwoofer signal there, but is that wiring harness hard to get at? Would I have to loosen or remove the seat? How hard is that to get back in!??!
I would say my biggest hurdle so far is just getting that speaker signal to the amp.
Also, I have a 5 farrad capacitor. Would anyone recommend installing that too? Someone on reddit said they are useless, but it's just sitting around. Worth it at all, or no?
Thanks in advance!
