I just completed installing the upgrades in my system and the front right door speaker is distorting badly and I can’t figure out why. I am using a PAC 2.4 active line out converter that is connected to the front speaker outputs from the head unit. From there I have 4 channels out of the LOC feeding into Dayton Audio DSP-408. The first 4 outputs are feeding a 4 channel amp that is driving the front door speakers which are Polk Audio DB-692 and JBL tweeters in the A pillars. The 5th and 6th channel out are feeding a 2 channel amp that are driving the rear door speakers which are Polk Audio DB-652. The 7th and 8th channels are linked together to feed a Kicker HS-10 hideaway sub. The 4 channel and 2 channel amp gain were set using a 1khz test tone and a multi-meter and the sub amp gain was set with a 50hz test tone.
With the exception of the DB-692 in the right front door it sounds really good but the right door sounds horrible. It is distorting and sounds really shrill even at low volume. I have reterminated the wiring at the amp and where the speaker wires from the amp tie back into the factory harness and that made no change. It sounds like the speaker is blown, but it was fine when it was just connected to the head unit before I installed the DSP and amps. I’m going to pull the door apart in the morning and see if the speaker is possibly blown just to make sure but if it is, I am not sure how, I haven’t played it very loud or pushed frequencies to it outside of its range. I wanted to check here and see if any might have any other suggestions of what to look at. I can shut off that speaker in the DSP, but I would much rather figure out the problem and fix it.
