Are you ever going to run a second 10w3-3-4 or will this be your only one.?For one sub.I think they rate them 500rms now,the first batches of the 10w3-3-4's were 300 rms.I ran 2 of them on a Alpine mrp 650-m--600 rms @ 2 ohms in a vented box @ 1.125 cu.ft.For 1 unit--to be run @ 4 ohms..JL Audio 500/1 or if you have the 300 rms sub the the Alpine mrp 500 m=300 rms @4 ohms/500rms @ 2 ohms 2006 CEA rated power.Alpine50..
