For 2013 I'm wanting to go a little bigger and I'm trying to get loud for a change so I'm gonna strap 2 DC 5k's @ 1 ohm. I have a mechman 270a alt and 5 XS D3400s. This is in my daily suv so it'll be used mostly few music, maybe a comp here and here. A lot of demos and vids. Right now I have 2 AQ hdc4 18s on 1 5k @ 1 ohm and I'm looking to sell them soon and get some new subs when adding the 2nd amp. Any sub suggestions that will handle 10k @ .5 ohm on a daily basis for music. My enclosure is 11.5 cuft tuned between 38-39hz. It's a non wall and I'm gonna keep it that way for awhile. I've considered custom level 5s, tantric shd's, fi subs. Any ideas guys?
