I placed an order for two BTL 15''s on Sep. 10th. I ordered dual 2's but would like to change that to dual 1's. Is it too late? I emailed sales as well as sent a PM to Shawn a couple days ago but have not heard back. Would someone from Fi please contact me.

Before you do it, are you just wanting to use 1 large 1ohm amp now instead of two smaller 1ohm amps?

If you are intending on wiring things below 1ohm for a daily scenario I would highly suggest you do not do it.

Exactly, I agree. I will be using two RF T4000's. At first I was going to run each at 0.7, but have decided it'd be safer and more efficient to run each at 1.4 ohm. So I need dual 1's instead of dual 2's. If it's too late I'll just do 0.7 on each amp which is what I've been doing the last couple years so far with great luck/listening habits.

I want to wire D1's in series, instead of D2's in parallel.

Are you strapping the amps, or one sub per amp? Either way you will want d2's so each amp will see a 1 ohm final load. Or if you want a final load of 2 ohms per amp get the d1's.

BTL's aren't true 1 or 2 ohm subs. It's 0.7 or 1.4.... Right???

Yes think of them as "true" d1, and d2 subs.

Ok, I'll stick with dual 2's.

That is DCR, not impedance.

If you want both amps at 1.4 then you would want to keep the D1 parallel them up to 1.4

I'm going to stick with my original order of D2. Hopefully my flip flopping hasn't pushed my order back. Today is four weeks...
