2015 Jeep Compass

I recently purchased a new Jeep Compass and immediately started looking into redoing the entire interior with a new audio setup. My last car was a Chevy Impala, and I had an Infinity Kappa system and was very happy with the sound. With the Jeep, I was really trying to recreate that sound which was in the Impala. I began with a new deck and all new wiring throughout. For the full range, I started by trying the latest models of Kappa components for the front and 6x9 coax for the back doors. While it did sound nice, it just wasn't cutting it for me. Was it the speakers? Was it the amp? Sound was nice but just not loud enough for me. After auditioning another brand or two, I decided to step into a whole other level of price and performance, something I didn't initially plan on doing. A friend of mine who used to run a car audio shop told me about the loudest and smoothest speakers he'd ever heard, the JBL 660 GTI components. I like to keep my business through Crutchfield, so I ordered a pair of the model that took the place of the 660s, the JBL 670 GTI comps. They are expensive but worth every penny. Please realize that these are rated at 150RMS per ch/300RMS per set, so amp them properly. These comps LOVE power, and can absolutely handle way more than what they claim. I paired them with Rockford T800-4AD which puts out 189 wpc accord. to birth sheet which makes them sound truly amazing. I plan on getting another pair for the rear and using time alignment to prevent localization.

Pros: Very tough/rugged construction of all parts. Mid drivers play extremely low once broken in. When using speakers at this price point and up, it can be beneficial to install proper sound deadening, 0/1 awg cable to dist. block if running more than one amp, quality RCAs, and consider a deck with features like DTA and hi/low pass filtering or if you want to keep the stock deck get a DSP. Oh, and they play LOUD and CLEAN!! Just be patient as they sound better as they break in. Well worth it!!

Cons: Crossovers are large, but can be hidden under a seat. Older model (660 GTI) was bi-ampable but these are not. Getting the front sound stage config properly can be challenging. I used my dash tweeter locations and angled them towards the opposite headrests, combined with either a deck or DSP with dig. time alignment makes everything come together nicely. Must be amped up properly to enjoy full benefits. Sound deadening at least your doors is a MUST when running speakers of this calibre.
