I am installing an Alpine CDE-HD137BT and will be using the HU speaker out cables to the stock amp to to wire up the fronts to the door speakers and the rears to the speakers. (My original HD skipped CDs over bumps.) I have also replaced my door speakers with a set of 609CS Infinity speakers - I had a blown passenger speaker. The new 609CS 6 inch are heavier and larger than the stock and the tweeters are also larger and much heavier. My new Apline has an equilizer built in.
So my doors (6 inch and tweeters with the new Inifinity Crossover connected) will be controller by the front speaker HU settings and the subs will be controlled by the rear speaker HU settings. I have wired everything up as shown in other threads on this site - separating the inputs into the amp from two channels to four channels. Getting ready to test everything on NYears day.
Should I still install this mod for my front speakers? I realize that my subs (rear) will only produce low bass frequencies based on the amp design and the fact that I am using hte original subs still.
Thanks
Only if during your testing/daily operations you drive the door speakers too much (the midrange specifically as they both use the same feed) to distortion at your 'normal' volume levels. The cap mod was to tailor the mids above the bass frequencies distortions. For many, this clipping sufficed to let the volume be set louder so the subs can actually be felt/heard. So, its only after you test/operate that you can determine if you want to try this mod.
