OK you guys I have two 12inch digital design red line subwoofers witch peak power is 1800watts but I got them wired to a 1200 but yes what's way to tune


Tuning is a function of math related to the enclosure..You need HXWXD and material thickness, Speaker type and SPL and port size if you are going to have it ported.

I never used my 10sw klipsch subwoofer and it's not working.


Check the cone surround - unless it is a rubber butyl surround, the material self destructs in air after about ten years and the speaker will stop woofing.

I installed an aftermarket radio in my car. The car's speakers sound pretty bad when I play some of my music off of my iPod. Is there something I can do to improve the quality or would I be better off...


1st rule of audio, make sure you have a high quality source material, 2nd, make sure you have decent speakers in which to hear that material, 3rd, make sure you have a quality device to play said material, 4th, have sufficient amlifying power to hear the material at the desired level. if you have all these things, you are well on your way to bliss my friend!

Simple things first:

Is it powered on? (sorry, I know that's too elementary)
Is it connected properly? (you have a cable securely plugged into your receiver's subwoofer line level output and securely plugged into the subwoofer in in the subwoofer)
Is your system configured properly to send a signal to your subwoofer?
  • Does your receiver have a menu system you can use to manually configure your speakers?
  • If it does, have you told your system that you have a subwoofer?
  • If it does, have you set your other speakers to "small" (believe it or not, even with full-sized floor standing speakers this is a good practice)? Sometimes, if the other speakers are set to Large, an AV receiver may not output a subwoofer signal.
  • Check all the rest of your receiver's speaker parameters through its menu system.
  • On your subwoofer, do you have the Level turned all the way off?
  • Where is the cut-off frequency set? (if it's set too low, and your source material doesn't go down that low, you may not hear anything through it)

Is the cable good? (use a multimeter to check)
Is the receiver outputting a signal through the subwoofer out port? (again, use a multimeter to check)

That's all I can come up with for now. Good luck.

I get a red light on the back panel labeled power. No green light. I don't think the PV 600 is working but when I run the channel check through my Pioneer THX receiver I hear sound. Any thoughts?


The PV600 and PV400 have auto-on circuitry that turns the subwoofer on when a signal is presented, and turns off if no signal is detected for 15 minutes.

Not knowing which Pioneer receiver you have I have dropped in the steps for No Sound from Subwoofer:

• Check that the subwoofer is connected properly, switched on and the volume turned up.

• If your subwoofer has a sleep function, make sure it is switched off.

• Make sure that the Subwoofer setting is YES or PLUS (see Speaker Setting on page xx).

• The crossover frequency may be set too low; try setting it higher to match the characteristics of your other speakers (see Speaker Setting on page xx)

• If there is very little low frequency information in the source material, change your speaker settings to Front: SMALL / Subwoofer: YES , or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on page xx).

• Check that the LFE channel is not set to -80dB , or a very quiet setting (see Bass Peak Level

on page xx).

• Check the speaker level settings (see Channel Level on page xx).

Regarding the Large vs Small assignment of speakers, what they mean isn't so much the physical size but the ability to handle real bass. Large if Yes.

Sony CDX GT200 Sound quality (missing some wave sounds, poor or no vocals on tracks & so on) It may be stuck in ATT mode but how do I get it back to normal auxillery mode?. Thanks


I would first check your speaker wiring or how the speakers are integrated with the player. They may be wired "out of phase" which would cause cancellation of the source material, therefore, for example, canceling out vocals. Certainly check how you wired the speakers to the unit

Depending on the source, you typically only hear program material from the three front most of the time. Ensure that you are using surround encoded source material or try changing surround modes.
