Re: No low bass

What type of box are you using and what size? A sealed sub-box will give you more hit and more bottom end but drops off on higher frequencies. A ported box is much more efficient and has less drop off at different frequencies but is much larger, but with a Yukon you probably don't have to worry about the size of the box.

Re: No low bass

Check the wiring of the woofers. If one speaker is wired improperly, it can cause the loss of bass and will make the woofers bottom out easily. Check inside the enclosure at the terminals and at the speaker.

I cant get my jl audio w6 10s to give off much bass with the jl audio 500/1 amp

here is a manual for your subwoofers:

use the wiring diagram for 1.5? (1.5ohm) with 2 speakers. the diagram for 3 speakers will not work, because it would bring the load down to 1 ohm, and the amp cannot go below 1.5 ohm.

to set up the amp:

under "preamp output section", on the "output mode" switch, select "amp filter"

to set up the levels: start with the amp gain pretty far down- with the input voltage on low for line level outputs from the deck, and on high for speaker outputs from the deck. now turn your cd deck as far up as it will go until it distorts, then turn the cd deck down to just where it stops distorting. now, you can start to turn up the gain on the amp.

on the filters, youll prolly want the cutoff filter around 100hz @ 24db slope. start with the infrasonic filters off, but, if you do get into them, try centering between 30 and 60hz on either, and, possibly dropping the cutoff filter to 80hz.

Amp settings

It's going to be mainly "what sounds best", but I'll give you a start.
  • Set the gain to 50%.
  • Set the LP filter to 12db at about 80Hz.
  • Set the infrasonic filter to ON and at about 20Hz.
  • Set the Bass EQ to ON, Q to 0.7, center freq to 40Hz, and boost to about 5dB.
The other settings are going to be based on how the system is connected to the head unit.

If this occurs with the head unit plugged directly into the amp (no signal processors inline, you probably have open shields on the head unit.

To check the shield ground, disconnect all RCA cables from the head unit and measure the resistance between the RCA shield on the head unit and the case of the head unit. It should read ~0 ohms.
