Poor bass from doors

[djunified]

did

you add sound deadener to the outer skin of the door panel or just the

panel the speaker mounts to? you want to sound deaden the outer panel

... and did you roll the sound deadener on or just apply with your hands

? from the picture if looks like the sound deadener is just placed on

and it is not conforming to the panel.

to get the best bass out of a door you need to stop the panel from moving and vibrating which cancels out sound.

Yes

I did apply sound deadener to both the inner and outer panels of the

driver and passenger doors. I covered almost the entire panel with

deadener. And at the same time, i used the specified roller along with a

heat gun. Obviously i did the outer panel first, as I covered the large

holes on the inner panel with sound deadener as shown in the picture. I

was told that doing this with the dynamat would make the door act like

an enclosure with no place for air to escape. I hope i did it right

deadener

is not the best thing to use to cover the holes but yes you did all

that right ... in that case it sounds like what everyone else is saying

... the head unit

Just a little update on my

situation, i just finished doing a radio install for one of my friends.

He has a 2000 VW Golf with the non-monsoon system. What i installed for

him was a Jensen VM9225BT double din radio. The radio fits nicely in the

dash, and more importantly, I swear he had a sub attached with the

amount of bass that the speakers reproduce. He has factory speakers too!

The best i can describe what my system sounds

like would be the equivalent of playing a speaker in "open air". Imagine

placing a bare speaker directly on the table and playing music through

it. You get no bass. Well thats what my system sounds like.

I

was also thinking that its the headunit thats the culprit. I bypassed

it by connecting a spare Clarion CZ109 directly to my speaker amp. Well i

played some decent music off a cd, and the result was exactly the same

as the factory unit.

That leaves three culprits. The speakers, amplifier, or the door itself.

My gut at this moment is that the speakers are bad. Pretty soon ill buy some RF Powers or something thats $300 a pair..

before you spend more money, check your wiring. Are the speakers in phase? If they are out of phase, there will be no bass when centered, and more when balanced left or right. Check this first.

i run those MB quart onx components. look else where. i have 2 sets per door . they sound ok but theyget a lil muddy in the midbass range.

Its income tax time, so when i get my return I see myself getting those mb quart components along with the JL Cleansweep. If that don't work i'm gonna give up and blame the design of the door itself.

Can you post a picture of the setting on your mids and highs amp?

Is there space between where the speaker mounts and the actual sheet metal of the door?
