And was very happy with The Tweeter / soundbar speaker upgrades. About an hour for all four.After reading a few posts it's still unclear which speakers are best. I have the stock base system in my jku 10. I'd like to hear from people who have made the switch what speakers did u get? How's it sound? How much did it break the bank?
The Alpine fronts that you got from Sonic, did you need a adapter?Speakers are very subjective. You really need to hear/audition different brands of speakers to see what you will like.
That being said, I used Alpine SPR-17S separates for the front speaker replacements, and Alpine SPR-17C coaxial speakers in the soundbar. I also used a JL Audio Stealthbox sub. All of that is powered by an JL Audio HD900/5 amplifier.
I purchased the Alpine speakers from www.sonicelectronix.com and the JL stuff from Crutchfield (authorized dealer for warranty purposes).
