Basically my current setup is listed below and for some reason my front mid (one side) crackles (distort) when the bass hits really hard sometimes. Basically with certain songs, not all, the front mid will crackle like its blown when there is major bass coming from the woofer.

This problem has been on going for sometime but has gotten worst recently. At first when I switched the RCA from left to right it would make the mid problem change from left to right, so I took it into the shop and they said there was something wrong with that particular RCA and they fixed it. After about a month the problem has come back, so what they did now was hook up a Y splitter to the good RCA and plugged the splitter RCAs into the amp and the bad RCA is not plugged into anything, but the problem hasn't gotten better. NOW when the bass hits, both speakers crackle instead of just one side as before. And the weird thing is if I TURN OFF THE SUB, EVERYTHING sounds fine even if I go louder SO basically I can get rid of the problem by turning the woofer off.... but I don't want to do that.

They said it might be the output from the headunit itself and I may need to send it in to see if the out puts are bad. Can it be anything else like the amp or my settings? I can take pictures of my settings if that will help just LMK.

Thanks

 

Make sure the speakers are not really blown. Check all the power/RCA/speaker wiring, look for a short. Ask the shop to swap the HU and RCA and see if the problem goes away. Better yet, find another shop, these guys either don't know what they are doing or don't really care about your problem. Even better, find a local EJ to help you.

Good luck!

 

speakers were swapped from diamonds to the current mb quarts, so speakers are fine.


thanks

i will turn the gains down as suggested.

the HU is set to POP, sub level set to 5, stinger battery, phoenix gold RCAs, speaker wires go from amp to crossover, crossover to speakers. i don't think theres any tuning on the crossover so the amps are what i use to adjust the freq. as dipicted below. if theres anything else you need let me know.

ENTIRE AMP


FRONTS W/ ISSUE MB QUARTZ


FRONT SET AT 100HZ


REARS SPODS w/ Diamonds


REARS SET AT 175HZ


FYI: the rear amp outlet is running my fronts and front outlet is running my rears, don't ask me why they did that but pretty much they got lazy imho. i tried switching the rcas to see if that will fix anything thats why you see the Y-splitters connected to the good side, but it didn't fix the issue.

LMK if theres anything else.

 

I had a similar problem, but on top of your symptoms, my HU was cutting out. Check to see if any of your speakers are grounding out. Also, seeing as when you switch the RCA's from left to right, the problem changes from left to right, check and make sure that the polarities are properly aligned at the speakers.

I dont know how any of these things would possibly fix itself after the sub was unplugged .

Okay, I want to see if I have this straight:

Front left speaker (mid) is making bad sound.

You inverted the RCA's (took the front left and front right and swapped them)

So, the problem should have moved to the other side, but didn't.

You've also swapped out the speakers.

So you've eleminated everything before, and after, the amp.

So you're left with the amp and the wires going from the amp to speaker.

Am I reading this correctly?

 

You got most of it correct.

The problem at first was just the front driver side, so I switched the RCA's from L to R and the problem moved accordingly. The shop said the RCA was loose and fixed the problem, but it recently came back, so they unplugged the Black RCA you see laying there in the pics and Y splitted the RED RCA. It sounded okay for a minute or so, but by the time I got home both front speakers were crackling at about 17-20 volume.

Since then I changed the front RCAs (the bad ones) to run the rear SPODS and am currently using the rear RCAs for the front to see if that will fix the problem with the front mids and tweets. I'm just not sure if replacing all the RCAs would solve the problem and it would be a PITA.

Thanks

 

Thats the only thing thats tripping me out is when I turn the woofers off (going into the menu option and set subwoofer OFF) the problem goes away. I can drive with my mids and tweets pass 25 volume and its fine, but once the sub come on the problem reappears.

The shop said the vibration is shaking that bad RCA, but why is it still occuring with the Y splitter and the good RCA?

 

sounds like the RCA's might be bad, or the signal from the HU to the amp might be bad. Either of these would explain the "bad" noise switching when the RCA's are switched.
