Thanks, guys. New amp!

I have been using a Hifonics ZXi-6400 for two years now (cost me $135 new from ikesound). The past month or two, my channel 1 speaker keeps cutting in and out. After some tracking down, I've determined that it's the amp that is probably bad. It seems like a hardware issue, maybe something loose...

My setup is just a simple MB Quart RAA4200 powered temporarily by a weak stock head unit (max 40w out). I was driving home today, hit some bumpy asphalt and something shifted in my truck and caught the rear left speaker wire, pulling it out and shorting it against the case (or maybe the other...

Yeah, I was pretty disappointed with that, too, but their explanation for busting it was right. Once there's a crack or leak somewhere, that's it for damage to the car. If it wasn't the sunroof, then it could be a rip in the surround or something (and leak down and out). It won't be glass...

The only time I had one side sound quieter than the other is when I had a short. Maybe check your wiring?

- Digital is the type of signal passed on the wire, it's not the wire itself. - The wire can be an optical cable, a RCA cable, a 3.5mm cable (like what Creative products use), or any cable really because the cable has nothing to do with the signal. - Yes, digital coax is just a single RCA...

Thanks for your reply. I got the MB Quart since I thought they were supposed to be good, but now I'm finding threads about how they're not. Sucks. I know I have to comprehensively test every little arrangement individually, but I've had no luck so far and was hoping for more advice. Thanks...

I just tried it, and the whine is still there (just harder to hear over the engine, but same pitch, same volume). So far, I've individually pulled out and put back in speakers and input, I've cranked the gain up and down, and I've tried it with both the engine on and off -- and the whine is not...

JimJ: I guess what I should've said is that the whine persists, whether the input is plugged in or not. I had pulled them out to test if it was caused by the input line catching outside signals Loud3: No, there's no fan.

I have a MB Quart RAA4200 purchased new. I've only owned it for two months and haven't really used it since I'm still working on the install. I've been trying to debug this problem for the past week and finally gave up and am asking for help. The amp WHINES... I never noticed this before...

To explain phase difference requires a brief lecture on sine waves. Basically, when the sub receives a signal pulse, it moves from center to forward, to backward, and then back to center. A 180 degree phase shift means when it receives a pulse, it moves from center to backward, to forward, and...

Hmm, I know this is just a old thread being resurrected, but I too had a horrible experience. I second the sentiment of paying more for a reputable company. Communication is non-existant and they don't seem to know what's going on. Every time when I'm able to get in contact and ask where is my...

tweeter right now is selling the MB Quart Discus series 10" sub for $25 here. It might not be the best, but it's cheap and decent.

Ah, well, if it looks like this, it's autumn: Symbolically, it breaks down to Grain/Rice, Fire, Sky/Day. Put that together and you get autumn. As for recognizing characters, after a while it just becomes a symbol that represents "Autumn" and "Day". It's just a symbol. People do it with...

I can't make out the first symbol, but the second is "sky", "heaven", etc (depending on context).
