I have a AVH-P4400BH head unit going into an Alpine MRP-F600 100 x 4 at 4ohm amp powering 6.5 mb quart comps up front and 6.5" comps in rear doors (no tweats in rear) Alpine MRP-M1000 powering 2 Dayton Audio HO 10's in ported box all in an 09 Mazda 6.
Problem is the gain on the mid/high amp is all the way down (both channels) and still gets a little to loud to quickly as you adjust the volume, its not really bad.. but would prefer to go even a little lower. I think 40 is max volume on the hu, by the time I get to high 20's to 30 its already the max volume I would want the mids/highs.
The sub amp gain is at maybe 1/8th and its fine overall I would say. I would actually turn it up a tiny bit more but the rattles in my car are so fing annoying I'm not touching it until I sound deaden.
