Doesnt sound good

I have a jvc h\u 6 inch speakers in the doors and 6x9's in the shelf and it just distorts at pretty medium levels and it has no bass at all, i broke the wire connector bit of the 6x9s a little but it was only the bit where you slide the thing onto so i just wrapped the wire around it and duct taped it... i dont know if that has anything to do with it.

Re: doesnt sound good

My suggestion is try using electrical tape and make sure you wires are not making connection with other wires or any kind of contact with the chasis. That can sometimes mess with your sound quality and can cause your speakers to act up.

The bass in my Sony 3-way 6X9 speakers wont work

if these speakers are several years old, chances are that the left one is just blown. could be a loose wire, but if not, it would be cheaper to get new speakers than to get that one fixed

I installed a Pioneer DEH-P800PRS head unit and 4 Kenwood KFC-1662S speakers in my 2003 Dodge Dakota extended cab truck. I used a Kenwood KAC-5204 2 channel amp connected in parallel. Sounds good at lower...

Hello.... sorry to hear about your problem. Bass is the ultimate evil of coaxial speakers. You have a couple of options here, and this is just my professional opinion because I do not know what your lifestyle details, such as truck space needs, type of music you listen to, budget, etc. If you are looking for alot of bass, the best bet would be to use 2 external amplifiers, 1 for the interior speakers, and 1 for a subwoofer. You would then need to purchase an electronic crossover. With this setup, you can remove all of the low frequencies from the coaxial speakers and put them where they belong, with the sub. You will gain EXCEPTIONAL clarity and a very high volume before distortion level. Again it will depend on what your budget is and if you are willing to compromise on some cab space. The only other option you have at this point is if you are wanting to play your music at high volume levels, you will just need to reduce the bass level as you increase volume. I hope this has helped. Good luck with your venture!!

I have a problem with my car speaker/tweeter

Sounds like you have the ground and live possibly the other way around from the head unit to the speakers. The reason for you hearing it from both the tweeter and the speaker is that the tweeter is connected in parallel to the speaker.
Swap the wiring and try it.

I have 2 kenwood 3011 400 watts rms and 12oowatts peak power each 1 is blown and wonderin about upgrading 2 the Hifonic Olympus OLM1612 would this be a good upgrade even thought i only a 400 watt kicker...

yea for sure thats a good upgrade. You shouldnt havebeen able to blow the kenwoods with 400 watts though-meaning that they probably blew from distortion which causes heat(fast) Check your gain on the amp start it out at 1/4 gain and turn up your deck to the point where you can hear distortion from your mids and highs or to the maximum level that you listen to your music at. If you're jamming out at a level that is causing distortion then you will be sending a distorted signal to the amp as well. The amp then amplifies the distorted signal through the subs which overheat and blow. So find the distortion spot and then turn it down just a little bit till it clears up your sound-then adjust your gain on the amp up slowly until you cant hear it getting any louder. Once you have done that you have reached the limit of CLEAN power that you are going to get.Thats where you want to keep it. Watch the bass boost too if you have the bass up on the deck and then crank up the bass boost on the amp it really f's up the signal too. Good luck

Typically you will hear a popping sound when the bass hits, or you may not have any sound at all.......If the sub sounds good then your ok.

On a side note, pulling on the cone while the sub is in operation can damage the unit because it cannot move freely under load

VT Commodore 6x9 Speaker install

Hello taz_is_1,

Sure, it's OK as long as the new 6X9's are the same impedance as the door speakers.

Unless there are already wires and cutouts for rear shelf speakers, the installation will be pretty involved. And while I'm not sure of the Holden product, it's sister versions, Chevy Lumina and Omega, does not have such cutouts or wiring.

Wires going into the door interior for window controls, locks, and speakers will all be in a bundle and go from the vehicle frame into the door through a flexible rubber connector with grommets on both sides. You'll need to run your wires from the disconnected door speakers back through the same grommets to avoid pinching and damaging them. After you get them back into the vehicle interior, you can run them under the trim or carpet to the trunk area under the rear shelf. If you have never done such work before, I recommend you get someone who has to help you. You'll need to make an appropriately sized cutout to mount the 6X9's. And depending on the material, you may need some kind of reinforcement and/or spacers. Also, look out for anything underneath the trunk lid that may come into contact with the speakers. There's usually 2 metal rods than span the width of the trunk and run almost directly under the shelf. They will have to clear the speakers in order for the trunk to open and close properly.

It's more work than a simple speaker exchange with a good pair of aftermarket speakers. And the benefit is minimal. A really good set of 5 1/4, 6 1/2, or 6 3/4 Alpines, Bostons, or Infinitys will sound better than a mediocre set of 6X9's any day and you don't have to cut everything up to install them in most door openings.

Hope this helps.

What duz level adjustment do


The level control controls the input level coming from your head unit (receiver) to the amp.

Your Sony users manual is a little vague on how to best adjust the level and other controls.

Here is one method that some installers use and works well with most amps.

Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.

Hope this helps.

Car stereo im trying to build

I guess the question you need to ask yourself then is how much money are you willing to spend? If you are looking for a sound quality system then it WILL cost a lot more than a DB all out BASS system. The system that you have picked out isn't a bad one but as with all systems this in only half the story. You will need to have it installed well to get the best from the speakers that you have chosen too. If you want to have the stealth look in the cabin then it's pretty simple, but you will not get the best sound quality or should I say imaging as the OEM locations usually are no good for this.

I would suggest that even though you keep things looking stealthy in the cabin apply sound deadening to the doors as Asian cars are generally quite tinny unlike German cars. This will make a big difference in terms of overall sound quality & help keep out the road noise so you can hear every little detail of your personalised system.
