Mids and tweets keep shutting off!

[ambrizd528]

I'm having this problem in my wife's g6 all of her mids keep Turning off, but bass keeps going. I have alpine 300.4 powering 4 kicker ss 6.5s the amp does not go into protect nor does it shut off voltage stays above 13.4 at full tilt. Sub stage is 500 watt alpine pushing sundown sa-12 running at 2ohm. I tried searching the forums before I post topics as most system related problems are usually discussed but not too many had my set up. Only thing I can think of is maybe loose wiring or crossover problem or recently bad ground in head unit. They don't shut off right away maybe after a couple songs at full volume when bass hits. running pioneer avh 4400 full volume I say is 17-18 I think they go to 35 or something both amps set to nominal dd-1 should be here tomorrow.

Reconnect all the wires

first thing i would do is check the remote to the mid amp

damn remotes always mess with me

[ambrizd528]

I'll redo the connections when I install the sound damp I bought taking those door panels off and on is a pain compared to my truck. I did redo the remote wire I had it going to the sub amp then the mids now it goes to the mids amp then subs

most likely there is a "tweeter protection" circuit in the crossovers for the components, once too much power is giving for too long, or the protection circuit gets to a certain temperature it will cut the tweeters off, until it has cooled, or the volume is turned down to accommodate safe wattage going to the tweeters, which then they start working again.

There also maybe a similar protection circuit on the mids in the crossover too, not sure, never seen the inside guts of those components to know.

Chances are, if you are powering them with an amp that will give the components their rated rms power handling, or even less than rated power and your continuously having issues with it triggering the protect circuit(s), you are more then likely clipping the amp, which is than putting out some DC Voltage instead of AC Voltage like an unclipped amplifier would do, and is triggering the protect circuit prematurely to prevent damage to the speakers.

My thoughts exactly.

Thanks for the reply hopefully I'm not clipping them, I will see with the dd-1 if how I have it set up now the signal is distorted. Amp is rated 50watts per channel 4 ohm mids are rated at 90 or 100 so underpowering and maybe clipping.

under powering the speakers wont hurt them if the amp is set properly.

properly meaning, the amp not distorting or clipping.

If under powering speakers would blow speakers, then speakers would be blowing every time you have the volume turned down, which that never happens.

Speakers blow when they are underpowered when the user thinks they are not loud enough when they are under powered, and turns the gain up, which is when you bring distortion and clipping into the mix which is harmful to the speakers and this is when the protect circuit on the crossovers see the clipping as an overload.

same happens to mine.. what i found is that one tweeter blew on me making my ohm change from 2 ohms on one channel and 4 ohms on another making the amp not send signal to mids and highs at a certain volume or loudness.. the crescendo tweeters are loud and did not know one was blown.. the fix was disconnecting the other other one and matching the ohm load on the amp. i then test it full tilt and never shut off on me again.. time for me to recone the tweeters

[ambrizd528]

I set the gain to nominal but maybe distorting the signal still. I'll have to check the tweeters too I think one might be blown, the dd-1 should be here today I find out and post results. Thanks for the help guys
