Oh man I thought my stereo was messed up. I test drove a G8 and was happy that the system has a least a little bump to it and then one I bought had barely any bass whatsoever. This at least bides me a little time before I decide what I want to do with the system.
I have not like the distorted uneven bass responce of the car since I bought used. Guess what it was already turned up all the way!
I turned it down to mid point detent and rechecked sound with all settings at std. and or off. Perfect. The mid bass hit finally was heard and no more ratting and distortion.
I also checked it with a bass tuning disk and spl meter. The readings concur with what I was hearing. 30Hz is still off the scale, but that seems to be the resonant frequency of the interior of the car.
FULL BASS BOOST MOD IS JUST DISTORTION.. TURN IT BACK DOWN. Mid Posistion or a little above is good. Not full gain!... AND DON'T ADD ALOT OF BASS AND TREBLE AT THE HEAD UNIT EITHER. IT WILL PLAY LOUDER AND CLEARER THIS WAY!!!
Trying not to preach, but most home and car subs are not setup even close to best, most accurate sound.
You should not hear the subs. They should just be there when called upon.
Holy shieate it sounds way better. Was looking into new subs for the deck now I'll just wait for them to blow like the rest of the factory speakers did LOl. Turned the gain up a little past middle and it sounds 10 times better than before. Weird but it def works. Thanks OP. Very nice.
It's not too bad of a job to get to the amp, a little time consuming. before i put mine's back together, I made sure I had adjusted it to where I liked it so I would'nt have to be digging it out again.
If you replace the door speakers with 4 ohm units you will have to turn the bass boost to mid point or lower to compensate for the higher output from the subs (2ohm) than the output from the 4 ohm door speakers to balance things out.
I am glad they had this on the subs at least (they needed it on the center channel too)...
Take off the battery cover. Pry up the the side panel just ahead of the batt. Stick your hand under there and feel around. You will eventually fine a round knob about a half inch in dia. You can turnit with one finger if you get the rright angle and pressure. There is a detent for the middle position.
Out of curiosity i finally decided to check the level mine was set at, easy enough to get to without a hassle, and having long arms was a plus. Mine was at the min, turned it maybe 25% and has a much more full all around sound now.
