hooking amp up to 98 honda

I am having problems hooking up an amp to my 98 honda accord. I havent started to install it yet, so before i do i need to ask a few questions.

1. Do you think i should put the amp in the trunk, or the back seat of the car?

2. Where do i hook up the power sensor cable telling my amp when to turn on? The antenna is in the back window so i cannot hook it up to that. This is my main problem.

It all depends!

What are you going to run with the amp?

What size is the amp?

If you are just going to run the four speakers in the car, then I would just put it under the seat if there was room.  If your running a box, then I would put it in the trunk.

Grab the antenna turn on from behind the deck.  If needed, run it through a relay to turn on the amp.

I am going to run a box with the amp. What do you think is the easiest way to hook the amp up to tell it when to turn on? because i cant hook it up to the antenna, the wireing is in the roof i think. I could run it through a switch but where would you recommend hooking the wire up that goes from the electrical to the switch?

Use your WHITE/ red wire to turn on your amps. This is your switched 12volt source. As far as amp placement I would go under the seat if it fits due to it being less likely to be stolen. If not then to the trunk you go.

if u don't have an aftermarket headunit u could wire it to any power wire (+) that comes on when u turn the car on like on mine my cig lighter only comes on when i turn my car on and i just wire it to the back of it, i have a sony head unit but the antenna wire in the back of that isn't makin the antenna go up on mine for some reason, anyways my RCA cable has a 3rd wire so i used that as my remote

i installed a head unit and subs system into my cuz's 97 accord and only problem i had was the two screws i didn't know about in the center console below the shift console and almost broke it
