Thanks for this review. I have one LE-ST06d and two LE-S06d's installed under the rear trunk floor of a Hyundai Santa Fe, each one getting about 400W RMS with no problems at all. These are CLEAN sounding subs; the boxes are perfectly designed for the woofers, and the grilles actually come with the boxes instead of having to pay extra for them. I suggest at least two of these 6.5 subs if you have amplified front stage speakers, they can take the power and don't sound muddy.
