[QUOTE="logicalthought, post: 8070269, member: 653656"] I'm a car audio novice (but with a decent set of ears, I think) and have a couple of questions that are confusing me: I just had professionally installed (in a Boxster) a set of Morel Elate 903 3-way component speakers (woofers and mid-ranges in the doors and tweeters on top of the dashboard) powered by an Alpine PDX-F6 amp, with no sub-woofer and using the stock head unit. Although there's plenty of bass and the system sounds really good with the convertible top up, with the top down the vocals and upper ranges sound a bit harsh/metallic so I'd like to "warm them up" a bit, and I'm wondering if I could do this by tweaking the gain and/or HP/LP settings on the amp. Currently both gain adjustments are set at 50% and both filters are set at 60 hz. Do you guys have any suggestions as to how to warm up the vocals a bit? (I don't have access to an oscilloscope or voltmeter.) Also, I'm conceptually confused a bit by the filter settings, as the woofers (almost 9") are rated at 25-3000 hz while the low end of the midrange speakers is 450 hz, so what good does it do to set the HP filter below 450 (and yet on the amp it only goes up to the 200s). Thanks for any help on this! [/QUOTE]
