Posted September 14, 200817 yr My 100.2 was pushing a set of PG RSD's until the passenger side mid and tweet stopped working.....but the drivers side was fine. I replaced the PG's with a set of Pioneer TS-C720PRS and after two weeks I noticed the tweeter from passenger side was cutting out. Eventually the tweeter stopped working all together, and now my mid is cutting out on me......and it doesn't matter if it is at high volumes or low volumes. So basically to sum it all up: The channel that's pushing my passenger side has blown through two different comp sets and I'm wondering if something is wrong with the amp, or if I'm doing something wrong (the drivers side mid and tweet are fine). I don't have the gain up that high (which I know isn't saying much) and they aren't crossed any lower than 80hz.
September 14, 200817 yr I'd clamp the outputs and put them on an o'scope to see if anything's wrong...
September 14, 200817 yr Author Thanks for the suggestion Jim. I'll try and find a shop around my school that has an o-scope. So do you think I'm going to have to replace my mid now too? I already bought a new tweeter to replace the blown one.
September 14, 200817 yr I'd check it with a DMM to make sure, and try it with another amplifier to rule it out, but it doesn't look good for that if one tweet already fried...
September 14, 200817 yr Author Has anyone else had only one of the channels from a 2 channel amp give them trouble?
September 14, 200817 yr It happens, yes. The channels each have their own circuitry. Wouldn't be unusual for there to be a bad component in only one channel. I would think that both channels having problems would be unusual unless the problem was the power supply.
September 14, 200817 yr Author Thanks helo...I sent Jacob a PM yesterday asking him what I should do. I'm guessing I'll have to send it to Db-r.
September 14, 200817 yr Did you measure the output ? Check for DC ?Also keep in mind that the 100.2 is *significantly* under-rated, could simply be too much power.
September 14, 200817 yr Author No I haven't measured output or anything yet. It just seemed weird to me that only the passenger side was being affected and not both sides. I'm hoping that it's just error on my part with the gain....the amp has never gone into protect or anything, although it ran pretty hot during the summer. I just went for a ride and played two songs without the mid faulting at all, it doesn't happen all the time.....it's pretty random.
September 15, 200817 yr Are you using any sort of amplitude correction on the right side ?I know that I always fade to the right in my cars since those speakers are farther away.
September 15, 200817 yr Author The only time I faded to either side was after I realized that something was wrong. I heard the passenger side tweeter stop playing and come back on so I faded to the right to get a better listen. I have an alpine 9830 hu and it has time correction but I don't have that setting on at all.
September 15, 200817 yr Could also be a coincidence too, hard to say - if your amp is still playing fine it is probably fine. Only thing you should check for is DC on that side.
September 15, 200816 yr you could switch the RCA's and the channels and see if it happens on the other side lol.albeit it would be much better to use a clamp/oscilloscope/voltage meter if you had them available.
September 15, 200816 yr is it possible that you have a water problem on passanger side causing issues like the crossover getting wet and blowing
