    installing amp this weekend, last minute questions

    ok, i'm installing my amp this weekend and ahve some last minute questions.
    1. where in the trunk could i ground the amp? i looked under the carpet and saw soem bolts, can i ground to those?
    2. what level do i set the LEVEL input sensitivity to so that i could match the stock HU?
    3. i want to install a switch so that i could turn my amp off while still having music in the car on. do i connect the remote wire coming for the HU into the "power" on the switch? and the remote wire coming from the amp into the "load" on the switch?

    thanks

    To tell you the truth I did the following

    1. There is a bolt at the top dead center of the trunk. I used that for my ground.

    2. Don't know

    3. Just put a switch off the remote wire to the amp. You will still get sound out of your speakers, and shut off your amp.

    Hope that helped.

    BTW If your running your stock deck, I ran my speaker wire off the rear speaker. It takes some time but works great. Hits really hard.

    1. Any bolt that goes into the metal frame of the car is fine.
    2. If you are using line level inputs then I think you set the sensitivity to "1" if you are using speaker level inputs then you have to play with it to get the volume you want. Since you mentioned matching the stock system I guess you'll have to fiddle with it until it sounds good.
    3. Switch the 12v turn-on lead. I don't quite understand your power/load terminology, but that's what you would do. DON'T switch the power supply from the battery unless you want to buy a high amp switch.

    1. Any bolt that goes into the car (metal) should work. However, make sure you clear the paint from the area. Bare metal is a better contact. Just sand a bit in the area around the hole. If you want to get fancy, use some of the goop they use for the battery so that it doesnt rust.

    2. Easiest way is to play it by hear. Play some of the stuff you listen too all the time. set it low, and start setting it higher as needed. if it starts to clip, then you want to set it lower than that and never go past that point. You want to get the highest volume without distortion. Play it by ear.

    3. Not sure about the question, You're using the stock HU right? What is the amp driving, just subs or all the speakers?
    Here's my thoughts if the above is the case.
    There should be a "remote" wire from your amp. When there is no power to it, the amp should remain off, even if the 12v wire is still connected. This is used so that when you shut off your radio, the amp goes off also.
    If you're using the stock HU I don't think you get a remote wire. In that case, your amp should have the following leads, 12vdc, ground, remote/power switch, speaker in/outs, rcas.
    The remote and 12v need to both have power in order for the amp to be on.
    Out of your stock HU, I would use the Front Left and FrontRightchannels for the door speakers in the front. And use the RearLeft and RearRight as your inputs to feed your amps. That way you could control/tweak the volume in the bassbox with the fader/balance controls.
    If you wanted to completely shut off the amp, I'd throw a regular, radio shack switch in series with your remote lead circuit.

    I just gave you a general idea, so I forgot to mention, make sure you protect your stuff with fuses also. You rather burn a $1.00 than $$hundreds$$ on an amp.

    Or thousands if you burn up your car from having no fuses.
