An amplifier wiring kit that gets the job done

The following review is for SK4681, which is a part of the bundle you are viewing.

Had everything I needed, including 2 larger sized (8ga - 12ga) butt connectors, which I ended up using.

I should noted that I did end up buying a separate Stinger 4-Channel RCA cable as well. I didn't require speaker wire as I was able to re-use my cars wiring.

Great speakers at a great price!

The following review is for TDX65, which is a part of the bundle you are viewing.

Needing to upgrade the stock speakers in my 2013 Hyundai Veloster, I shopped around for several weeks before deciding on these MTX 6.5 speakers for the back of the car. With 5 star reviews on just about every website, nice looking specs, I figured I can't go wrong. They've been in the car for several days and they're starting to warm up and I can really hear the difference. I see they're discontinued but the newer model will probably be pretty close. I listen to hard rock and like a deeper sound from the back. I haven't added the amp & sub yet, but without them, these speakers are filling in where the stock speakers were lacking. The stock speakers in the back were horrible. Very muddy and rotten volume. The MTXs are very nice and I don't have to turn up the volume.
Being one of the more important specs I look at when considering speakers, I loved that the sensitivity was a good number. Most of the other speakers in the same class are under 90dB, so this being 92 was the main selling point for me - along with the reviews - and price, of course.
The speakers were easy to install. I can't give all 5 stars because i don't know how durable they're going to be AND giving 5 stars for "Look/Design" is silly. They look like speakers. Nothing special.
I can't do this review without rating my experience with Sonic Electronic customer service. I called the number with a question about installation for my specific car. I read somewhere that I needed to take out the back seat to install the left, rear speaker since there's no door there.I just wanted to know where the bolts were that I need to remove. The installer said that I did not have to remove the back seat. Well, he's wrong. It's impossible to remove the panel without removing the back seat. I shopped on this site because they provide the number to call the "experts". The guy I spoke to was nice and professional. He was just wrong. The other negative is the fact that these speakers need a different bracket to fit and Sonic Electronix doesn't provide the right size, nor do they suggest you buy the right bracket. The other "big name" electronic website shows they include the right bracket on these MTX speakers (no extra charge) and they included the bracket (no extra charge) that I'm going to need to replace the front speakers i just purchased from them.
You see, customer service is important, and in this case it's prompted me to shop elsewhere. I might buy here again if it's a great price and I don't need to call 800 number for help.

They work great! Have them in my Grand Prix and they are awesome, but definitely need an amp to push them properly!
