Easy to fit on my crewcab silverado
Emmanuel T on Dec 25, 2016
I have used pioneer products for years. I have never had any issues with any of them. I have bought other radios and speakers before and all have not lasted as long as Pioneer have. So Pioneer is a a brand that i trust.

will this fit the ts-swx251 sealed box?
A shopper on Jan 31, 2015
Best Answer: The dimension measurment online for the speaker should help you determine that. Just make shure you have enough air space within the box and that the box has the correct diameter cohesive to the speaker. I don't know the box well, hope this helps.

I have an amp that puts out 450wts. Is that 2 much for this speaker?
A shopper on May 19, 2015
Best Answer: Need more information to assist. 450 watts at what ohm? Is it a single channel amp? if not, how many channels. This speaker should handle 450 watts of 4ohm clean single channel power. If you are shallow mounting the sub, you may want to reduce the gain on the amp so that you get the best this speaker can offer. Also, you want to pay attention to crossover frequencies so that you aren't trying to go to low on the Hz.

Best Answer: I have the same box in my 08 F 150 with a Kicker Comp S 10" sub (9 1/8" cutout), fit perfect. If this Pioneer 10" requires a 9 3/4" cutout you could modify the hole in the box to fit. Mark the center of the existing cutout and mark a 9 3/4" circle around the existing cutout. Could be cut with a jigsaw.

How do I find out how far the woofer cone extends out while under load? It will be for a box facing the floor and I want to have clearance under full volume.
Daniel F on Nov 17, 2015
Best Answer: Hi Daniel,

The "XMAX" tells you the excursion of the driver:

Xmax (millimeters) 6.5 mm
