Infinity 60.7cs / 62.7i install in JBL Prius

You should be fine putting in coax speakers in the rear and just disconnecting the factory rear tweeters.

 

So how did it sound with the infinity speakers replacing the JBL speakers?

 

I have the 62.7i all around in my pkg3. The sound is VERY clear and it can withstand much higher levels of music, however the bass is disappointing. To me, the bass is similar to the stock speakers. Overall, a great buy if you are planning on adding a small subwoofer.

 

I have to agree. I had these Infinity speakers in my last car and they sound really nice but they do lack the bass. A powered sub for the rear is a really good idea...

 

I just finished my install of the Infinity 60.7s in my 05 package #6 (JBL system) yesterday. I have to admit I was very surprised in difference this upgrade made. Install was very smooth. I did have to drill new holes for the mains and use the adapter that came with the speaker kit. The fronts are an easy upgrade. Do not use the crossover that comes with the speakers. The JBL amp has the cross over built in.

The rear speakers are full range so you will need to disconnect the tweeter as it has a crossover built in. Thereby leaving the full range signal to power the new speakers.

For my money (and more importantly time) I put 60.7s in the rear too. Connect the rear line to the supplied Infinity crossover and run two wires, one to the main and the other to the tweeter. The sound is wonderful. The muddy base is gone. Just crisp tight music. I love it.

A side note: I did install Dyanmat Extreme and a Basslink sub first, but I consider this speaker upgrade to be the most important contribution to the sound system. Even with the sub disconnected the base is very good, add the sub and WOW!

Chris,
You’ll be glad you went with the 60.7s. There a great match for the JBL amp (2 ohms).

As for they Dynamat Install, let’s just say it was a lot of work. It did make a difference but I’m not sure it was worth the time or $$s. I have pics I’ll post here soon. I installed it on the outside door panel and the inner panel. I used about 45 ft. It made the biggest difference around the speaker. (Took care of all rattles.) If I had to do it again I would just put some on the outer panels and round/behind the speakers. I have about 5 feet left and will throw that in the hatch area.

I feel the speaker upgrade was by far the biggest bang for the bucks. I got the speakers off e-bay for around $350 for all four. The next improvement was made by installing an Infinity Basslink Sub. (I already had it from my previous car.) I posted my install pics here last month. It is a good match for the 60.7s. The last is the Dynamat.

If you want to talk before you do the install send me a message and we can chat. (I don’t have time to write a speaker install but it was similar to Sparky’s instructions.)

I love the system now. There is no doubt that these upgrades are well worth it those who want a great sound system for the Prius. The only thing that is missing is MP3 which I am waiting to see if the 06 JBL unit can be dropped in my 05. Otherwise I will purchase an Ipod and adapter.
