Customer Ratings & Reviews

Worked Great! in my 2008 STI

Buying these made installing my new door speakers so much cleaner and easier. It became total plug and play to install the new speakers. Definitely worth the money. I would definitely buy these again.

Works Great on 2004 Celica GTS.

Worked well in a 2012 Toyota Tundra.

I used these in my 2012 Toyota Tundra. Worked perfectly and a good fit.

worked very good

These make changing speakers a breeze, very good product.

Also works for 2011 Subaru Forester

Great product for aftermarket speaker installation if you want to keep factory harness intact.

Mitsubishi eclipse spyder GS 2002 infinity sound system

Works great with my Mitsubishi eclipse spyder GS 2002 with infinity sound system (4 speakers + 1 dashboard speaker + 2 tweeters).
The Metra 72-8104 fits perfectly with the 4 main speakers (2 doors + 2 rear speakers).

useful

good for not having to splice speaker wires into aftermarket speaker...not totally necessary, but useful and time saving. fit well into factory connector. why not

Simply amazing! Entry level?

I can not believe these are considered entry level speakers. I am picky and these sound really great for their price point. The mid-bass is spot on, and blended really well with my 10" subwoofer. When it comes to tweeters, they’re super smooth and very clear, not harsh or ear piercing at all. If you are looking for an incredible sounding set of components without the big price tag look no further.

Worked well in the front doors

I own a 2006 Toyota Matrix XR with a 1ZZ motor. These fit perfectly in the front doors, I would suggest getting your own bolts and nuts. The nuts they give you are garbage. In my car this adds about .5 inches so you get a full 2 inches of mounting depth with the window rolled all the way down. They didn't however work on the back doors, but those doors really didn't require anything special anyway.

Works Great for Mitsubishi Lancer 2003

These plug right into the Mitsubishi Lancer wires.
Works great!

Easy installation

I purchased these to make installing speakers in my 2012 Impreza easy and clean. They worked perfectly!

3 stars

for the money there great but a very cheap feel to them, one wire pulled out of the connector but not a big deal. they worked and worked good, just a cheap feel, but good for the money I suppose

Solid speakers for the money

Got these for my old Prius to have some better speakers than stock. Running them on an old Alpine MRP-F300. They perform pretty well thus far. Handle power good and can pack a decent punch. I think once they're broken in they will sound even better. The tweeters leave some to be desired. At certain frequencies they don't sound the best, but these are budget speakers so I cant complain. These aren't audiophile quality but they will make an old system sound better than stock for sure.

Professionally made to fit the factory wires without any guess work.

Perfect fit

Perfect fit in the front door in my 2015 Toyota Corolla, thank you.

By AMBRO on November 13, 2015 Verified purchase

Wires had to be modified

the wire end that goes to the speakers were to small to fit on the connection on my RF speakers, also the wires were to short. I added longer wires and soldered them to the speakers.

Perfect

mounted some Infinity primus to these. Great build and simple installation.

Good spacers.

I used these on an '05 Subaru Legacy. The screw holes didn't match up but that was expected since this is actually for a Toyota. I used self tapping screws and made my own holes. It gave me enough space behind the speaker to fit my NVX VSP65's.

By Joseph on February 2, 2020 Verified purchase

Fit well

I used this to install aftermarket speakers using the OEM connectors and it's a very easy and quick installation. No splicing needed.

By Stephane on July 1, 2015 Verified purchase

Perfect fit

They fit perfectly In my 2016 RAV4 and we’re easy to install. They lined up perfectly with the factory rivet holes and then just bolted in like a breeze.

Smart buy

A no-brainer if you're replacing factory speakers while still using stock wiring. No splicing needed. Happy customer!

Metra 72-8104

Plug in perfect, pre-butt connected if needed. Wires are long enough to route around anything in the way of your connections.

Metra 82-8148

Fit really well. the hardware they give you isn't great and if I had looked before I was installing them I would have bought different nuts and shorter screws.

Best buy for easy speaker connections makes everything simpler. No solder, no fumes, just plug and play...don't forget the heat shrink and you're all set.

Just perfect

Fast shipping excellent customer service good price.....just perfect 100% recommended

Great value and definitely worth it.

Plug and play, that's really all you can say. Great product.

By Daniel on April 26, 2020 Verified purchase

No issues

This came free with my order, I did not need it but it fits perfectly and works as advertised

Plug and Plan, super easy!

These adapters are great for the ease of installing new speakers. There is no guess work on polarity of wires, it just clicks into the factory speaker harness and the other ends to the terminals on your speakers. These are great for systems under 75w RMS a speaker, any more and you will want to run a heavier gauge wire anyways.

By Christopher on April 4, 2018 Verified purchase

Awesome product

I definitely love these for being able to reinstall factory speakers and keeping your nice ones when you get rid of a car so your not cutting and splicing wires and leaving a mess for someone else. Plus they make installing aftermarket speakers a breeze.

By Eric on April 28, 2020 Verified purchase

Did not fit for my car

This product did not fit my car, so I returned them

By JASON on April 30, 2022 Verified purchase

Does it’s job

What can I say? They do exactly what they’re supposed to do. I really liked that the speaker's connections came pre-crimped on. It saved me a ton of time on my install.

Work smarter, not harder!

These adapters make life so much easier! Why solder and fuss when you can plug and play!

By Frederick on September 23, 2020 Verified purchase

Great value

This Metra 72-8104 speaker quick connections are great, I used this on my 2015 Camry and it fit just right and you avoid cutting the vehicle's original wires. very satisfied, and at a great price and quality.

Spades do not fit RF speakers, nor rear speaker connectors on 9th gen Corollas

TL;DR: If you're putting non-Rockford Fosgate 2-way 6.5s in the front doors of your 03-08 Corolla, these will work just fine. But don't buy them for your rear deck speakers or component speakers with external crossovers, otherwise they're a waste of money.

These were recommended by Sonic Electronix for my 2003 (9th gen) Corolla when I purchased new RF Punch 6.5 component and 6x9 speakers. They DO fit the OEM connectors for the front door speakers, but DO NOT fit the rear deck speaker connectors. The spade connectors present also DO NOT fit Rockford Fosgate speakers, or at least the Punch line of speakers, nor do they fit the external crossovers provided with the front component speakers. Both the negative and positive spades are too small. Additionally, the wires are far too short for those using an external crossover mounted inside the door itself.

I ended up using the wires supplied by RF for the front speakers as the length and spades in the Metra adapters were insufficient. However, the rear 6x9s did not come with any speaker wire. I didn't want to put my rear interior back together so I cut the plastic connector off the Metra adapters and pulled the negative spade connectors off of each and replaced them with ones I had on hand. I then used the positive Metra spade for the negative on the speakers and the larger female spades I had on hand for the positives. I then hardwired the cut ends into the factory harness with butt splices and heat shrink. So out of the four adapters I bought I only used two out of eight spades and four out of eight wires.

Additionally I wasn't very impressed with the spades on the Metra adapters. It did not take much effort at all to just pull the spade off and expose the bare wire. It would not survive the yank test I do when I install new connectors on wires. I can't imagine they'd come undone driving around or anything, but I like my wiring harnesses tight and secure nonetheless.

By Dwayne on October 24, 2020 Verified purchase

Time savers

They're a great product! Sonic needs to change them to they work with 2004-2009 Toyota Prius tho. They worked just fine in my Prius. So simple to use. Two butts connect or some solder and a quick plugin and you're done. So simple and useful.

By Bryan on March 10, 2020 Verified purchase

Works great !

These adapters worked very well for installing new speakers in my car. Stock speakers came with speakers being held in place with an adapter being integral. This kit let me install the new speakers without modifications.

Very handy wire pigtails

I purchased these wire pigtails adapters to install my Rockford Fosgate 6x9's in the rear deck of my 2016 Corolla S. They saved me alot of time, and simplified the installation.
I highly recommend these wire pigtails

By G on May 10, 2023 Verified purchase

Perfect fit

Used on a 22 WRX, for front and back door speakers installation. Fit perfectly. Small detail unnoticed was the speaker end leads were super tight. I had to gently open them up with a small flathead. Overall very satisfied with the clean and easy instal.

By Carlos on January 29, 2023 Verified purchase

Excellent and easy to install

I only ran into one issue with these. They are for the front door 6x9s on my 2007 toyota camry. I thought they were capable with my rear deck 6x9s as well but ended up cutting and using the original kit with the car.

By Japheth on April 4, 2024 Verified purchase

game changer

I only spent like $250 (paired these with the 6x9 coax set) and got a system that makes me smile just from the bass alone, the highs are crispy clear (try covering a tweeter while a song is playing and you’ll notice how sharp they really are), and they work great in my home system too. running these paired with the 6x9s and a high powered 12 makes my civic sound like a box chevy

Ring mounts work fine.

I like them.

NVX 6.5"

I ordered 2 sets of these and they sound good. They are running off OEM amplifier, and you can feel the air coming from the bass. To get the most out of them, you definitely need to give them at least 100 watts to each speaker. Eventually I'll upgrade to an 8-channel amp.
