I currently have an Alpine MRP-M850 (800@2ohm). I like it, but I want more power for a new sub. Here are my options:
1) Buy another MRP-M850 ($150) and run each amp to one coil on a Dual 2 ohm sub, gain matched, for 1600w total. The amps aren't strappable, I'm aware, but I know if I match the gains as closely as possible, i'll be fine.
2) Sell the Alpine, buy a single, big amp that can run ~1300w @ 2ohms. I was thinking of a used AQ2200D or DSC2000.1D, or anything else right around $300 (suggestions for anything cheaper?)
I'm not competing or anything, so I'm not worried about the possibility of a tiny db loss from running a pair of amps slightly out of phase. And since this a daily rig, I'd rather run the amps (what ever I end up choosing) at 2 ohms to keep damping factor at a reasonable level, compared to 1 or .5ohm per amp. Also, please don't say that running 2 amps to 1 sub will be difficult to wire up, it's a non-issue.
Here are the questions: Which set up would be less stressful on my electrical system? Each Alpine has a max current draw of 75A, so 150A for 2. Since I can get ~1600w for a around $250 (cost of 2 Alpines) vs ~1300w for $300, does the benefits of a single amp outweigh the cost and power difference? And would there be any AUDIBLE consequences from running 2 amps on a single sub, assuming they're properly gain matched?
