Crutchfield Customer Review (What's this?)

Pretty good fit in 1983 Toyota pickup - had to dremel out the holes in the corners just slightly to accommodate the stock speaker mounting plate, but otherwise fit was excellent.

These things sound great for 4" speakers!

A very good bargain.

Written By D. Kocak, Dravosburg, PA on Friday, February 13, 2015

Crutchfield Customer Review (What's this?)

A reliable quality and bargain for the price. You will realize the bottom end will not be a booming base, but it does bring through the bass guitar runs well enough. Midrange is good to excellent. Highs are also acceptable. Remember what you paid! Installation went easily with supplied installation kit. Another great bargain. Sound quality was best with CD play. Radio not good but believe it's the radio reception quality.

Pros: Easy installation, high quality ratio to costs.

Cons: No cons worth mentioning.

Good value but not hi-fi

LR Owner

Written By LR Owner, New Jersey on Wednesday, November 12, 2014

Crutchfield Customer Review (What's this?)

Great low cost replacement speaker for the dried-out factory units. Synthetic cones sound great and should withstand off road moisture. Had looked for a good replacement to fit in the factory LR door depth and to fit the factory grill. Speaker mounting tabs require trimming to fit within the grill diameter and some foam washers keep things tight.

Pros: Correct size thanks to the Crutchfield "fits my car" feature, they were correct. Great sound for the size and good frequency range, output and clarity for a 4" replacement.

Cons: none

Good Product at a Great Price!

Crutchfield Customer Review (What's this?)

I purchased these aspeakers to replace a defective Pioneer speaker in the front door of my 2007 Aveo. I have to admit it was to cheap price that got my attention. I was a little scepticle, but I figured if they are bavcked by Crutchfield then they should be fine. The install went smooth and these little speakers sound every bit as good as the pioneers they replaced. I like to listen to Metal and also some 70's style prog rock and blasting that stuff out of me Kenwood deck the sound is excellent. All in all a good purchase for the budget strapped person.

Pros: Price, good sound quality and sturdy build!

Cons: None yet- I'm sure for more money one can do better, but I like 'em!

Leave a bit to be desired

Written By Allen, Spartanburg SC on Monday, September 22, 2014

Crutchfield Customer Review (What's this?)

I used them in my Series III Xj6 Jaguar, replacing the original speakers. I knew they would have no bass, and since I was using a subwoofer, I thought they would be good. Sadly, they were also weak in the mid range which left me with a muddy, unsatisfying sound. Very disappointed, I removed them and reinstalled my original speakers, and the sound improved dramatically.

Pros: Cheap. Good hi range.

Cons: Poor sound, no bass, weak mid range.

Written By Dean C, Salisbury, MD on Friday, April 18, 2014

Crutchfield Customer Review (What's this?)

4" speakers are often a necessary evil. They're a common replacement size, if you don't want to do any cutting, but don't deliver the necessary bass. The Sound Ordinance P-40 speakers are excellent replacement speakers. The quality is great, they fit well with existing grills (they do not come with grills), and they produce excellent sound.

Pros: Quality of materials Sound quality

Cons: Grills not included. Must use original grills.

Most bang for the buck!

Written By JNS, Hemet, CA on Monday, February 17, 2014

Ordered these P40's to replace the 35 year old and dried up speakers that came in my MGB. Needless to say the sound is from day to night and no buzzing. The price is so low that I am amazed at how they do it. Still using the original AM/FM that came in the car. Actually hear decent bass & highs now when car standing still. With top down and driving exhaust drowns out the sound which is fine for me!

Pros: Perfect fit in original holes make easy install. Comes with necessary terminal connectors.

Cons: I ordered cheap connectors which were not necessary and spoke to a Crutchfield representative before hand that should have told me they were not needed!

I got these for my wife's Impreza wagon sport as the only working speaker was the front driver side one. These fit perfectly in the rear doors and made a huge difference in sound. Since only the driver speaker was working in the front, I could really hear the highs from these speakers and they added alot of fill to the sound. Very Happy with them!

Pros: Great sound, and they fit perfectly.

Cons: They don't install themselves.

Better than my Toyota Supra Turbo OE speakers

Written By NickD, Wisconsin. on Wednesday, September 26, 2012

Crutchfield Customer Review (What's this?)

First off, the application, Supra only comes with 4" speakers mounted in a plastic resonant box like Bose. And yes, they do sound like a 4" speaker in a plastic enclosure just like Bose. Actually the rears are 4 1/2" speaker with a more like square frame. No big deal, used 1/8" plywood to make a gasket, outline identical to the old speakers, hole for these round speakers.

This was Toyota's idea of providing bass, actually, the cone diameter of the fronts are 3 3/4", rears are 4" not really that much difference. My radio is stock and have no intention of changing it thinking some day, this car will be a classic. But I did invert the spare tire so I could mount a 10" Overdrive Woofer fed by both channels into an amplifier I designed for bass with a 40 watt output, you want bass, I got bass and a fair amount of midrange to boot. These four inch speakers solve the missing high range for me, and that is exactly what they do. So very pleased with them. Not interested in blowing my ears off, but virtually harmonic distortion free if I turn the volume to maximum. I had to add a volume control to my woofer amplifier to turn it down, more interested in a flat response.

I did look over the entire range of 4" speakers that Crutchfield sells, as well as some completive options. Crutchfield for as long as I can remember always treated me well. I see the top of the line 4" speakers they carry have a 600 buck price tag, But bet, really not much different than these.

Pros: Inexpensive, weather proof cones, nice tweeters, easily handle around 15 watts and fit the application.

Cons: Not 18" woofers in folded horn enclosures.

Crutchfield Customer Review (What's this?)

Bought these for the rear doors in my 91 Volvo 240. They fit well but after installing i realized that they didn't come with speaker grills as shown online and in the catalogue. Crutchfield was good to handle the resturn in a professional manner. ending up going with a 4" polk dxi and very pleased with the results.

Pros: had pretty good sound especially for the money overall good construction. everything you need to install...except for speaker grills

Cons: don't expect thumping bass for a little 4" speaker. lightening bolt on the tweeter is a little cheap looking

good sound, at moderate volume

good speakers for the money. had to use 4in. because of mounting location. good sound well rounded sound quality , taking into account they are only 4inch drivers. no bottom end . i just turn the gain down on my 4 ch. amp and they balance nicely with the more powerful rears.

Pros: good quality and price for the size.

Cons: low power rating , no bass to speak of.

Great sound and value

Written by Jude, Director, Digital Imaging, on 7/10/2014 9:22:00 AM
My son just purchased a newer car, a 2002 Pontiac Sunfire and the sound system it came with was, well, awful. We sat down together and planned a system and since he was on a budget we decided we would go with our house brand Sound Ordnance for most of it, and we are not disappointed. We installed the P65-C in the rear deck using the SA69 6X9 adapter. We then installed the P-40 in the front doors with fabricated brackets we made from the 12x12 sheet of ABS #1208900903 and then used the Dynamat #15410415 to seal it all up and add sound deadening to the doors. We chose the JVC KD-R950BT for the Bluetooth and the generous power the internal amplifier has, plus the abundant color choices made it easy to match the red backlighting in the Pontiac. We needed bass so we used the Sound Ordnance B-24 and the Rockford Fosgate #575P500X1B we had from his previous vehicle and connected it using the EFX 8 gauge wiring kit #142PA8. We spent a Sunday working on this project and have to say it exceeded my expectations on sound. It sounds clear, the bass hits as hard as you want and the total price was well within his budget. This is a great system and it was also a great day spent with my son.
What are the Labs?

Get everything you’ll need to enjoy your new Sound Ordnance™ P-40

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You may need speaker wire to connect your speakers to your amp or receiver.
Keep your speakers clean and dry. They compress to fit behind your speakers.
These speaker connectors are handy if you're running new speaker wire or if your speakers have oversized terminals.
The right tools will help keep your installation simple and clean.
If your stereo doesn't cut the deep bass from your full-range speakers, a set of bass blockers can help prevent distortion and give you cleaner bass too.
