I believe its a matter of what you expect from the subs, deep bass, SPL, etc.
You can get different results with the same Sub by using different enclosures, i.e. sealed for audiophile performance; vented or ported deep bass; band pass pure SPL.
On the other hand depends in the amount of watts youâ??ll be running them. Makes no sense having a large sub with a small amp or vice versa.
I have in my Contour a single 12â? W3 JLAudio subwoofer in large vented enclosure, with 400 watts RMS from a Punch Amplifier a sounds great! Actually makes my rear view mirrors shake. I strongly recommend this subs. Hope this helps.
