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.

worked very good

These make changing speakers a breeze, very good product.

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

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

Excellent clarity

These speaker can handle a suprising amount of bass without distorting, even at high volumes. They sound crystal clear and they kick like 8" subs. Well worth the money.

Awesome speakers

i just bought these speakers and i love them they are a steal for the price nice highs and decent bass

Works on 2008 Subaru Impreza

Fits 08 Impreza factory speaker harness.

Fits Subaru

Worked in my 2011 Impreza!

Worked great

They fit my car and made install easier. No problems at all

parts fit great

Would buy these parts or similar part again. arrived in a timely matter.

great quality

these fit with no issues or concerns, great product quality!

A perfect fit

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

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.

MTX TERMINATOR #653 KILLER SPEAKERS FOR THE MONEY

I was going to replace the speakers in my 2000 Saturn SL2 with factory original speakers. In doing research I found the MTX terminators to be a better replacement. For my Saturn SL2, the fit was flawless and I used the oruginal fastners. I did solder the wires to the speakers though. The sound quality blows away any factory speaker by miles. I never knew this stock radio had such good sound.
I can verifie that they do fit a 2000 saturn SL2 in all four speaker holes.

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

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.

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

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.

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.

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.

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.

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

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

Not bad

Not a bad speaker for the price sounds pretty good

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

MTX TERMINATOR653

they fit into the car really well and sound great even with the stock receiver

Great sound

Great sound overall. Adjusted the deck settings and perfect speakers .good bass .crsip and clean for what you pay for

Great Speakers for the price, but mid bass is lacking.

Okay, so I got these speakers 2 months ago when the price was $40. I wanted to replace my stock rear deck speakers in my 2006 Honda Civic Hybrid, as I did in the front doors in summer 2017... They looked nice, they are much more durable than the Pioneers up front, and I thought it was be nice addition to my Honda Civic in terms of Mid bass. Installing wasn't too bad. The screws that came with these speakers were too long and thin for the Adapters I bought, I would've had to drill through sheet metal. So, i bought shorter screws with a wider thread. After I installed, I was disappointed in its mid bass performance. The speakers I have in my front doors are 45w RMS Pioneers I got cheap from Best buy, and they sound much better... However, I think these speakers may need an amp. I don't have one yet, but plan to get one. I haven't applied any deadener to to rear deck yet. Maybe an amp and deadener could help increase mid bass in the car... Or Maybe 8th gen Honda civics need serious work in Acoustic treatment.

On the flip side, they sound pretty clear... But after all, I am running them off a factory radio. That could be partially the reason mid bass is lacking. I don't wanna give a bad review, but I will re-work some things and leave another review.

High Quality & Good Value

I needed to replace my blown-out stock speakers on my 2006 Silverado Z71 Truck. The Terminator653's really pump the sound from my stock head unit. I'll eventually replace my stock head with a new one but won't have to change the speakers as they are ready for more power. Easy to install too. Highly recommend.

Wiring Harnesses were a perfect fit for my 2004 Toyota Avalon

The harnesses provided an easy and quick modification to add terminal connectors to the speaker connectors. Would recommend!

By David on August 23, 2024 Verified purchase

Good sound

These are not direct fit replacement for 2002 Subaru Impreza. The had to have the supplied spacer or the window hits the speaker. Also the screw holes arent in line with the fatory holes. Other than that I am satisfied.

Good factory upgrade

Purchased to replace blown factory speakers in 2010 Chevy Tahoe due to water damage from rear door windows. 4 OHM speakers with low RMS that the factory head unit could handle. Speakers have nice sound for low cost with nice bass increase.

Speakers work fine with a factory head unit definitely improved the overall sound.Great buy for the price! Sonic electronic was very helpful with my order bc it was on backorder. Got it shipped in a timely manner once they got the product. Would recommend both this company & these speakers.
