Quick question. I have 2 15" Soundstream SPL subs 400 watts a piece, and i'm thinking of purchasing a rockford p3002 amp. I know it won't give me the full power that I need to power them, but will it work well enough and will it be safe on the amp. I don't want to waste a lot of money on something like this if it will just mess up the amp in the end. If anybody could help me out, then please let me know, thanks.

400 watts rms each??? or 400 max power

The subs can not damage the amp. The amp just drives current through the voice coil of the sub. If your amp is not as powerful as the sub will take then you will not be able to supply enough current to move the sub through it's full range of motion and it will not be as loud, but the amp wouldn't be able to tell the difference.

It takes a freak incident for a sub to damage an amp and it usually involves a serious failure of the sub so it would be more of an overpower thing than underpower.

Edit: I'm not sure if you're going to be installing this yourself but another way to mess up an amp would be to wire the speakers up with too little impedance. Check to see what impedance the amp is stable to, e.g. 2 ohm, 1 ohm. Make sure that you wire up the subs so that they don't go below this number and for the most power ideally you want them to be wired so that they are at the minimum stable value.

yes, what is the specs on those subs, I can't find much info on the net, must be an older model.

Just make sure, if your underpowering them, dont crank the gain to try and make them louder, you will just end up clipping the signal, causing distortion and thats how you cook a sub, not too little power, but by running a square wave through the sub, inhibiting its ability to draw cool air into the voice coil to cool down, it heats up and you have problems.

They are 2 Soundstream SPL15 subs, dual 4 ohm voice coils, 400 watts RMS handling, they're about a year and a half old so that could be why you maybe haven't found them on the net. But yeah thanks for the help so far guys made things a little easier. I knew I would have to underpower, but since they're big subs and a bit of a smaller amp i didn't know if there was such thing as overpowering the amp. Keep letting me know though
