I'll be running one set of Pro60s off an Alpine MRV-F545. The birth sheet on the amp states ~164w per channel into 4 ohms at 14V. Now in a perfect world I could assume that halving the resistance will double the output, so using that, the 3 ohm mids should see ~246w each at full gain. This may be a tad too much for them as I have heard the 200w arena is where they like to play. Maybe not. My main question is the tweeters... at 8 ohms, they'll still be seeing 82w at full gain. This seems like a bit much as well. I can always set the gains- just curious how many watts (roughly) I should run to the highs.
Another thing is xover points- I have a 9887 HU and will be running them actively through that. Should I leave the amps at full range or set their xovers to the same frequencies as on the deck as 'backup'? That may sound strange but I've had issues in the past where I set a HPF on the deck and the amp on full range and it seemed to want to respond to frequencies lower than what I set the HPF at on the deck.
What points have people set the xovers at running the bostons actively? I've thought about ~3.5khz... just not sure about the slopes, etc. I was thinking crossing off the mids at 3khz@-12db/oct and the tweeters in at 3.5khz@-12db/oct.
Sound okay? Obviously it is all in how it sounds to me- I just don't want a huge spike in sound around 3200hz and this is my first time running components active. Any suggestions would be appreciated. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
