Small problem... I have the new alpine type x components in my Z and the tweeters on them sound awesome, but the when the midbass hits on the 6.5 inch woofer, it sounds like its popping or something. It's been doing it since I got the set, now it's just getting worse... My question is, can I just buy a set of 6.5 inch alpine type r's or something and wire them up in the same spot? Any advice is appreciated.

 

Take off the door panel and see if you hear any noise. It could be somehting behind the door panel or the speaker is self could be hitting something. Most aftermarket speakers are a pretty tight fit.

 

i would be willing to bet that the cone is hitting the back of the grill.

 

The back of the grill? I'm confused... Is there a grill over the speaker that is behind the door panel?

 

If you put them in yourself, then take out the speakers and test them see if they are hitting anything. If you had a shop do it just take it back to them. They should cover it. I don’t think it would be the wiring because usually if you miss wire something it will a) not work OR b) just burn out but sound fine.

 

I would take it to the shop i had them installed at but i'm at college 9 hours away... I might have to muster up the courage for some diy

 

they're probably hitting the door panel or the factory grill.

 

I was thinking that they were popping because they were blown... but maybe you guys are right, they could be hitting something, i need to take a look.

 

They may be popping due to clipping, What other electonics do you have in the system.

Try turning the gain down on your amps and see if the problem goes away.

 

HU: Alpine CDA-9833
Speakers Front: Alpine 6.5 Type X
Speakers Rear: Alpine 6.5 Type R
Amps: Alpine MRD-M605 Sub
Alpine MRV-F345 Speakers
Sub: Memphis Pro audio 10

I don't know how to turn the gain down. I really don't know much about this stuff, thats why I always have it installed professionally... How do you turn the gain down?

 

On your Amp there should be an Access Pannel that you can open to expose some tiny ***** that control the gain. (Look in your amp manual) You can usually turn the **** counter-clockwise a few degrees at a time until you get an acceptable level without the pop.

Although an Osilliscope is the best way to correctly set up the gain, you can do it by ear easily.

1) Put in some Dynamic (Meaning Loud) music.

2) Turn the Gain all the way down on the Amp

3) Turn the Volume up to 95% on the HU with the Bass/Trebble set at Flat.

4) Slowly turn the gain up on the amp until you hear distortion or clipping.

5) Adjust the gain back down until there is No distortion or Clipping.

All the gain does it set the proper input voltage level from your Head Unit.
Typically, when using all Alpine Brand Gear, You can set the Amp Gain **** to "Nominal" and be set without having to do any modification.

 

Sounds like they are bottoming out. Turn the crossover up to about 80 or 100 HZ on your amp and see if is still does it.

Another good Point.

 

Hell yes... After an hour or so of playing around with my amp I figured it out. I turned the gain down on the front speakers and the "popping" noise almost completely stopped. After I fixed that, I decided to find out what else my amp could do... So i adjusted the gain for my rear alpine type R's and sound is finally coming out of them! I asked the guys at the stereo shop why my rears were not producing sound after i replaced them with the type R's and ran them off an amp and they have no clue... I turned the gain down i think and Whalaaaa! Sound! My system sounds so much more balanced now.

 

Wow, you might want to post the name of the shop that doesn't know about gains on an amp so others can avoid them!!!

 

Yes... EVERYONE... Avoid STEREO ONE in Memphis, Tenn. Those people don't have a clue what they are doing... I'm a complete audio novice and I figured out more than them...
