QuestionWhen I moved the headunit to a new car, hardly any bass was going to my subs, even with the gain on my sub amp turned all the way up. So I decided to instead send the bass through the front RCA channel (instead of the subwoofer channel) and all of a sudden I could hear bass again.
Recently I blew the fuse on the + cable (the fuse closest to the battery). When I replaced it, all of a sudden I was having the same issue from the front RCA channel as I was from the subwoofer channel. Now I have to have my sub amp connected to the rear RCA channel to hear any bass.
What I find weird is that when I hook up my 2-channel amp to any of the front or rear RCA ports, the midrange and highs play fine through my components, so it's just the bass that's missing.
What is going on? Is it possible to blow out only the low range of the RCA-outs?
I'm almost 100% positive it's not a crossover issue since I've played with the head unit's internal crossovers (even tried turning them off), as well as the one on the mono amp to no avail.
The issue can't be with the source either because I've tried multiple sources such as satellite radio, AM, FM, CDs, and even my MP3 player to no avail. Besides, like I said earlier, the bass issue only occurs through the subwoofer (and now the front) RCA outputs, but not the rear.
AnswerSounds like internal damage to me. You wil have to try another sound source to test. An ipod with RCA adaptor works well. That way you can tell if the rest of the system is OK. Have you considered that when the fuse blew, the amp may have caused that problem?
