Great Sub for the money, Fits stock enclosure, excellent bass

Excellent sub for the price and fit perfectly into the existing Tundra enclosure (Crewmax cab w/JBL system) and used 1/2 in. foam weatherstripping to increase the depth and worked amazingly. The customer service staff at Crutchfield was amazing as well in providing me with all of the details needed to make this work. Back to the KFC-XW800F...It is a perfect complement to the other components and the new amp. I would HIGHLY recommend anyone with the factory JBL system who is upgrading to use this driver, as it is accurate, nice tight bass, clean and distortion free and drops into the factory enclosure (I added some poly fiber fill into the box to give it less resonance) . Two thumbs up and saved a boatload on an aftermarket enclosure.

Terrific for what it is

This really is an impressive little sub given its dimensions and specs. I powered it with 150w RMS from a Rockford Fosgate P300 and installed it in a sealed MDF box I made with exactly .5 cubic feet. It was one of the only subs I could fit under my backseat, which is why I bought it. It really complemented my Infinity components up front and produced very clean, tight bass. It's obviously not as powerful as a quality 10" or 12" in a proper enclosure, but it blew the Boss BASS1400 completely away that I tried for a couple days and couldn't stand. The Boss unit seriously lacked sound quality and seemed oriented towards teenagers who want the world to know they have a subwoofer but can't afford something decent. With a proper enclosure and amp, the Kenwood is approaching audiophile sound-quality. I got complements from friends who are true audiophiles and even one who is a professional DJ--but it's worth noting that the inside of my truck is tiny and I listen mostly to bass-heavy rock (i.e. Tool) and no rap.

XW800F

I like my system (highs, mids & lows) all to be on point. The Kenwood XW800F has taken my system to that point.

I like it

This sub does exactly what it is advertised to do. I had the need to build a custom, shallow odd shaped box (sealed) to fit where a sub is not supposed to and this fit the bill. If I were able to fit the 10" version, I would have but the 8" sounds great. I was just looking to fill in the bottom end (mostly rock/punk/alternative) and I am very pleased with my selection. I am feeding it with a kicker 140w @ 4ohms and so far this seems to be a good match. I couldn't quite get the recommended .5 cu ft, closer to .4, but used polyfil, made sure the box is well sealed and the result is good clean full sound. Great sub for applications tight on space.

Replaced stock sub in my 1999 Mercury Mountaineer

I needed a replacement sub for my blown stock sub in my 1999 Mercury Mountaineer. The stock sub is 8" and is pretty shallow. Only option I saw were the MTX, a JL audio, a Pioneer Shallow Mount, and this Kenwood. The Mach audio system has a 85w RMS amp(150w Peak), I didn't think this speaker stood a chance because it had lower db's than the other speakers that would fit, which means it needs more watts to put out the same sound. Anyways coming down to it all I found a tutorial on how to get the old sub out, and the screw that screws into the back of the stock speaker magnet. Really simple job to replace, I did it all in under 1 hour. I found a plug at True Value for 30 cents that filled the hole that was left after I put the aftermarket sub in. Very helpful info is available on online forums for those wanting to change the stock sub in expeditions, explorers, mountaineers.

Nice

Paired this with a pioneer GM5400t amp, which is rated at 380 watts x1RMS at 4 ohms and is CEA compliant. It hits hard but the Pioneer amp runs hot.

This sub fit a shallow area/enclosure.

This sub fit into my stock sub housing for my 98' Mercury Moutaineer's stock Mach audio system which is located on the passenger side spaced behind the rear wheelwell. It has a more shallow depth compared to the majority of subwoofers available in 8" but the sound is very good. Comparing the original sub with this Kenwood sub, it's pretty evident why aftermarket speakers are the way to go. The quality in appearance alone amazed me. The sales rep, Adam via instant messaging, was very helpful in helping me choose the right subwoofer to make the replacement installation simple. It took me less than an hour to finish and I'm really enjoying my tunes again. Thanks!!

Great for an 8" sub

I put this sub in a custom box I built for an 07 Frontier crew cab. The box has a little over .5 cubic feet. The key to making the sub sound great is having a good amp to go with it. I origanally hooked up a cheesy 300 watt amp and I couldn't even hear the sub. I ended up getting the Kenwood KAC-6104D 600 watt mono sub amp. That made all the difference. The sub sounds great. It doesn't hit like a ten but it fills in the bass that is missing from your system.
