    New subwoofer how to break in amp power level?

    NOTE- this isnt a thread to argue about if breaking in subs is a myth or fact, its strictly for advice, thank you.

    I just installed a 12" alpine type R sub with an Alpine MRP-M500 amp. The subs rated at 500 watts rms, and the amp is rated at 500 watts. Im wondering how to break in the sub, if i should turn down the amp eq level(which is what ive been doing all day, but now that i think about it seems like it could be wrong), or just play the volume low on the stereo? I have no way to adjust the sub level from my crappy Pioneer deck, obviously that would be the easiest way.

    Thanks.

    Just keep the volume low for a while. It probably tells you in the alpine manual that came with the sub. Do you have it hooked up to 4ohms or 2ohms?

    the amps 2 ohms, the subs 4 ohms, sounds great...theres a knob on the amp labeled 'sub eq'....im wondering if this adjusts the sub volume level, or the power going from the amp to the sub?

    I am going to assume you have the single voice coil sub. So it looks like you are running your system at 4 ohms then, the amp is capable of being wired to a 2 ohm sub. Thats all the 2 ohms mean. So you are looking at putting about 300watts rms to the sub which is a good idea. It is a safer idea. You will not be able to damage the sub as easily and the amp will run cooler. As for power to the sub there should be a "gain" adjustment on the amp. What you are supposed to do is get a tuning cd that puts out a certain frequency, then you adjust the gain on the amp so that the outputs to the sub are a certain voltage.

    to do this you will need the Cd and a voltmeter.

    My recommendation is just take it easy for the first month or so, keep the gain at a lower level and enjoy it!
