I have Crown XLS-1000 amp that is 550 watts x 2 @ 2ohms. I am only listing 2 ohms rating coz that's the load i will be using on the sub.
I have some very to-the-point questions before I make the purchase for diy project;
- Can I power a single DVC sub from 2 separate channels i.e. each amp channel powering each voice coil separately?
- Related to point 1, shall I go for Alpine SWR-1243D (4 ohm) OR Alpine SWR-1223D (2 Ohm)??
- How to correctly model the sub if I power both the voice coils separately as the simulation software assumes we are using both voice coils wired either in series or parallel??? I am using WinISD Pro Alpha
I think Alpine SWR-1223D will serve my goals best as I am not wiring the voice coils in parallel or series; rather I want to power them independently from two different channels of the same power source. I think I can get the max out of Crown xls-1000 down to 2ohms this way.
Also, although it is a stereo amp but the signal it receives is already converted in mono in the avr (80hz crossover) and I plan to feed same signal to both channels using a y-cord. I can level match both the voice coils with separate level attenuators for both channels.
Am I correct in my assumptions?? I need your expert advice before I buy the sub.
