Is this too much power?

[Jazz 10+ year member]

Hello

I want to bridge a 2 channel amp at 4 Ohm that will produce 290W RMS.

The 8" Subwoofer that i want to hook up to it is rated at 200W RMS and 800W Peak.

Will this cause a problem?

thanks for the help.

200RMS to 800 peak is a wide gap.

All you do is lower the gain on your amp so it doesn't push out around more than ~ 200 RMS to your sub. Set your HU to 80% volume playing common music you listen to and up the gain to a point where your sub doesn't distort. Then play with your bass adjustment and lowering the gain if necessary to reach the level of bass you like *without* distorting the sub. Listen for distortion in your trunk - not from your front seat. It may sound fine up front but in the back you're actually over pushing the limit of your sub.

If your sub can't reach a level of bass you enjoy while not distorting, then you need to look at upgrading the sub.

So, it CAN be done safely, right?

Or should i just buy an amp that puts out 200 W RMS just to be safe?

You can power a 50w sub with a 5000w amp if you wanted to.

x2, just set the gains right. And honestly, you could probably feed the sub a little more anyway after all things considered.

Yes. Like I said - listen for the distortion in your trunk and not from your front seat. Then you'll know you aren't overpowering the sub.

just run it, listen for signs of stress and/or clipping.
