[QUOTE="n2audio, post: 8371343, member: 540940"] using both would just steepen the slope. Just think about it logically...if you have the hu set at 80hz for example, and it's a 12db lp filter, you've clearly reduced a lot of the signal above 80hz. Then if the amp is set at 80hz as well, and also is a 12db filter, you've reduced signal strength again - in the same range. I don't know exactly how the math works out, but you're basically just "stacking" the filtering effect. That may sound better, or it may sound worse. Personally, if I had x/o's at my fingertips (as opposed to only in the trunk) I would definitely want to be able to toy with them. So i say either use the HU or use them both. [/QUOTE]
