I ran this off a 300W amp.
*cost effectiveness
It was the cheapest of the "low wattage" speakers and yet had an impressive range on paper. The only negative point (on paper) was the low sensitivity (84dB?).
When put to practice in the real world, these performed decently and I had no complaints whatsoever.

*installation notes
The 2 1/2" bottom mount depth was also a consideration, as I was not confident the larger 6.5" components would clear the doors.

The spade connectors came with plastic jackets so you don't have to add tape / heatshrink to the connections.

The red and black wires to the crossover seemed skinny... too skinny. Almost like 24awg. Not confidence inspiring at all. It may be irrational but we always feel good with chunky wires.

*Tweeters
The tweeters came with different mounting options (flush / pod). MB Quarts are reputed to sound overbright but these sounded just right.

Overall, a good buy on a budget.
