I'm still waiting for the GCON 10-D2 to actually arrive, but figured I'd take the time to look for a amp to power this beast now. It will be in a sealed box, in a saturn ion 2003. Looking to present a 1ohm load at amplifier, since I'm assuming that power at 4ohms is asking too much for my budget. No HO alt, or big 3 done yet, assuming it won't be needed yet though. I was mostly wondering if I'd need to feed it the full 750w, or if I could get by with less, near the 500w level? Just wondering as my budget is a bit tight currently, and I was hoping to grab the amp for under $150. Given what I've listed, would any of these amps work well, or are there others I should be considering? All listed are CEA-2006 compliant, so I'm assuming they all do rated. 1. Concept CC-D1200 (Apparently 750W @ 1ohm stable, manufacturer refurb, so not new) 2. Massive Audio N2 (800w @ 1ohm) 3. PPI BK650.1D (650w @ 1ohm) 4. Hifonics GLX1000.1D (1000w @ 1ohm) 5. MB Quart ONX1.1000D (1000w @ 1ohm) Thanks for taking the time to look, hoping I get some great feedback!
