2003 toyota sequoia limited with JBL premium audio. Took it to a stereo guy who said the factory parts are $200/door for the lower speaker set. This is already set up as a component system with a 6 1/2 woofer and a 2" mid-range in the door and a 1" tweeter in the upper door by the mirror. He suggested that we upgrade the system to sound much better with newer JBL speakers. They had trouble getting them in so I bought the system as they described and installed it myself ata fraction of the cost. Sounds terrible. Not happy. I think their recommendation was not a balanced system. I bought a JBL GTO608C 6-1/2" 2-Way Grand Touring Series Component Car Speakers System and put the 2" speaker for this system in the upper door as the tweeter as they described, and added JBL GTO328 3-1/2" Grand Touring Series 2-way Custom-Fit Loud Car Speakers as the mid range and added JBL GTO638 6-1/2" / 6-3/4" 360W Grand Touring 3 Way Car Audio Speakers for the back doors to just kick it up and be done with the failing stereo speakers. I tried to hook it up two different ways. I was wondering if I am suppose to USE the capacitor included for the hookup on the 3 1/2" set up as the mid for staters and am I suppose to then use the Capacitor connection box that came with this component system that has the in and woofer out and mid out for those two lower speakers since there was not one with the factory install. I figured that the JBL amp that came with the vehicle had the programming for the separate the freqs. There were three separate wires to connect to the 3 separate speakers. Also the rear speakers that i installed do not sound very good very bassy and somewhat distorted copaired to the factoy old paper speakers. maybe I just purchased low grade but I got what the stereo guy said he would put in to back it sound great. Any ideas? The bass is the worst prob. I have to turn the treble and mid wayyyy down to get the base to come up since we went with larger mid and tweeter speekers and it just sounds distorted. i also re-installed using the capacitor in one door and the one without sounded better to me but I did not play it with 2 capacitors installed. What may the additional capacitor do in the installation of the 3 1/2 speaker? It came with that speaker and was instructed to install on the + post. I did not try it without that capacitor. All connections were soddered. Please can you help?
First off stock wiring for speakers,and or amp are with minimal wiring.Rewire system for better sound quality,also use noise suppresors if needed.

FYI - I just took our 2004 Sequoia in because of speaker rattle coming from the front door speakers. Before I could tell them the problem, they guessed what it was. They see loads of Sequoias and Tundras with JBL systems due to the front door 8in speaker, basically, coming apart. His suggestion was to replace only the bottom 8in speaker, because the top tweeters usually are in good working condition. There is a minimal failure rate on the tweeters.
