Hi All,

We just bought this GS as Lexus Certified for Wife for Xmas gift.

Now she want to add more Bass, which we have no problem doing it on my 09 Acura RL.

My audio shop got it hooked up but for some reason, the bass doesn't sound as good. Possible, he tapping to a wrong Rear Sub output.

Here the setup:
1. 1x1500watts Mono amp by Hifonics
2. 1x1000watts 12" sub w/ enclosure.

Currently, tapped to Rear Sub output harness at the Mark Levinson Amplified in the trunk.

I feel the subwoofer sound do have vocal within and not pure bass.

I just wonder if anyone have done this before or might recommend on which wires for me to tap it.

Thank you very much for helping.

You may have tapped into the wrong wires maby to the rear speakers instead of sub. You can always have a low pass filter installed which will only allow low frequencies from getting to the subs. Most amplifiers have low pass filter adjustments built onto the amps. If those dont work just take you car back to the guy who installed it and have him tune/tweak the subs or fix it.

Yeah, he did something wrong or the gain is turned all the way down? Which doesn't make sense because the good installers will usually tune your amp before they return the car to you. Did you install a bass ****? If so, it may be turned all the way around.

I just got my 12" JL w6 with a JL 500/1 hooked up, and the thing POUNDS!. I leave turn the bass **** maybe 25% and that all I need.. I even have to turn it down sometimes.

Like Al13nv8d3r said, take it back to the guy and have him look at it.

Thank you guys for your quick respond.

Do you know which wires color did your installer tapped?

Usually, my installer tap by the rear sub itself. But since the amp is closer n much easier, I told him to tap from there.

If no trouble. Can you take a pic of the where your installer tap and which wires color.

Thank you.

Sorry, I won't be able to. About to jump on a plane, but I think he tapped from the head unit as i didn't see any cable going to the rear deck. Did your installer not do a sound check with you when you came to pick it up?

Hi,

I think I got the bass to hit harder and clear now. but it still needs some tuning.

I lowered "Low Pass" to 250Hz from 50Hz. I got more clean pure bass now. Yeah!!

But now, I have another issues. ;-)

I have a bass controller which in the front. I can't seem to completely turn off the bass when my kids in the car. I turned the bass controller to 0 and system bass to 0. But the bass still pounding.

what I eventually trying to achieve is:

The bass is there when I need it. ;-)

Thanks

Try lowering your Level/Gain on the amp until the bass stops hitting when your front bass controller/remote is all the way down to zero.
