I was thinking today about having Pro Audio subwoofers in a car. I mean their generally cheaper, and they are much more efficient. I once wanted to run an 18" Pro Audio sub in my car but the issue was it was an 8 Ohm woofer which was difficult. But If I had 4 woofers I could get an impedance of 1 Ohm which is perfect for most amps.
These for example:

The description seems to be missing but the title says '1000w', so we could presume 500w RMS, so with 4 18" woofers I would only need a 2000w RMS amp (I'd go a bit over but just as an example).
Are there any member rides on here using Pro Audio subwoofers?
How would 4 of these compare to my single Fi SP4? I would assume Pro Audio subs wouldn't be able to play the lows as well but tuning could help?
