Where does the remote wire, connect to the Head unit??? Where does the remote ground hook up to the head unit and does the amplifier ground have to be attached to the remote ground...?

The remote wire from the amp should be hooked up to either a wire that says remote or power antenna. Some wire that becomes hot(meaning it's getting power), when the head unit is on and off when the head unit is off. On most head units it's either a blue wire or a blue wire with a white stripe. As for the remote ground i have no idea what that is, never heard of a remote ground. The amplifier ground has to be attached to the cars body somewhere, like a screw in the trunk that is attached to some sheet metal.

i would reccomend hooking the remote wire on your amp to the remote on your h/u because on some decks when you are playing a cd then your power antenna lead losses power causing your amp to turn off. and as for a ground just pull the carpet back in the trunk and hook it to a screw.

Some older head units don't have remote turn on's, that's why i suggested the power antenna thing. As for the grounds, yes for the amp you do that. But he said something about a remote wire ground, and i've never heard of one, unless he's got something mixed up.

I dont know, in the amp kit my friend got, when we were putting his system together, it gave us 2 remote wires. The remote ground wire which seemed to be attached to the head unit, then grounded to the same place where the amp ground was, after that i questioned all my previous knowledge of amp installation, and thats why i am asking you guys.

Well, the only wires i've ever used are: the remote wire which is spliced into the head unit, the ground wire for the amp, and the power wire for the amp.

Some, no offense dude, cheap kits put in "remote grounds". All this basically is, is a ground wire that connects the ground of the stereo to the ground of the AMP to avoid a difference in potential, thus causeing ground loops. Something these manufacturers don't realize is that the stereo is already grounded to the chassis, and if you ground the amp to the chassis then you aren't at a different potential. Some people I have seen use the "remote ground" on really small amps where they don't want to ground it in the trunk or right at the amp, for instance if it is mounted under a seat. I don't recommend hooking it up in any case.

I just installed my friends subs with this amp kit, that I have been talking about, and nothing happened when all the connections were made. The amp turned on, so i assume the remote wire was working. But the fact the subs werent moving wasnt a good sign. This is what I have checked so far:

1. RCA connections

2. Sub wiring

3. Remote Wiring

4. Ground connections and wiring

5. Fuses

I havent checked the power cables, because the amp was turned on so it didnt seem neccesary. Im going to feel like a failure until I fix this problem. If anyone could help out that would be great.

My Kenwood amp had a remote ground. Since I had a stock head unit, I ran my remote to my radio fuse. It works fine, except the amp turns on with the vehicle, and not just with the radio. As for the remote ground.. I just put it with my amp ground. Oh well...
