SOURCE: No sound coming from my Infinity BU2 subwoofer.

I suspect that whatever semiconductor does all the amplifaction has departed this life. If you check the PC board it might point to a burnt out part or a blown one. If not look at anything big or with a heatsink on it.

I have the following setup: AV Receiver: Pioneer


Very common problem with today's receivers. Receivers made today don't have a true preamp section in the amplifier and do not amplify the sound to the extent of an older receiver. I have large 15" front speakers on my system, and have stuck with my 15 year old receiver just because I know that a new receiver will not have the power to drive them well. Many of the newer receivers need to be turned up to 50-60% before you can even hear anything from the speakers.

Can we use the subwoofer as an amplifier for speakers? it has jacks for speaker in/out, but i can't figure out how to make it work because the speakers have no sound.


I don't believe this hookup is amplified; but, if you have used the regular unfiltered speaker connections from your receiver/amplifier to hookup the subwoofer, the system will pass the signal thru the outputs subject to the crossover adjustment on the back panel. You cannot get the full signal if your system is sending only the bass signal to the subwoofer. I have copied the instructions below from the manual. You would set the high freq crossover to the low end of your satellite's frequency range. The full manual is here: http://www.jbl.com/EN-US/Products/Pages/ProductSupportDetails.aspx?PID=PSW-D110

High-Pass Control
• If you hooked up your subwoofer
as shown in Hookup
3 on page 4, you also have
the capability of adjusting
the high-pass frequency.
The High-Pass control
determines the frequency at
which the main speakers
will start reproducing
sounds. If your main speakers
can comfortably reproduce
some low-frequency
sounds, also set this control
to a lower frequency
setting, between 50Hz –
100Hz. This will concentrate
the subwoofer’s
efforts to the ultradeep
bass sounds, while your
main speakers continue to
reproduce the mid-bass
information. If you are
using smaller bookshelf
speakers that do not extend
to the lower bass frequencies,
set the high-pass crossover
control to a higher setting,
between 125Hz – 180Hz.
With this setting, your main
speakers will not have the
burden of reproducing any
low-frequency sounds.
• If you hooked up your subwoofer
as shown in Hookup
1 on page 3, the high-pass
frequency is fixed at 180Hz.
• If you hooked up your subwoofer
as shown in Hookup
2 on page 4, there is no
high-pass control. Unless
your receiver/amplifier
incorporates a high-pass
crossover, your main speakers
will continue to get a
full-range signal.
Final adjustment and blending
of the low-pass and high-pass
controls may evolve over several
listening sessions. A good
starting point would be to set
both the low- and high-pass
controls to the same frequency
and adjust from that point.

I have a four channel rockfor fosgate amp and I need to know hows the best way to connect Infinity Reference 1252w Car Subwoofers


Rockford fosgate usually work best with 2 ohm speakers. Depending on the resistance of your speakers, will then give you best connection. Check the resistance for the subwoofers. If the subwoofers are two ohm then connect them directly right and left. But if they are 4 ohm connect them parrallel (positive to postive, negative to negative and bridge the amp.) Good Luck, please rate.

How do i get the best sound from my infinity 1250w subwoofers


Make sure the ohm's are the same on all your speakers and amp.
You amp watt should be equal or higher then your speakers total amps.
You base box should be completely air tight, and have about 1/2 of the box stuffed with cotton.
Make sure you use a good thick speaker cables to connect from the amp to the speakers.
and finally, make sure your trunk seals tight and wont rattle... cause nothing sounds worse then someone pulling next to you and all you hear is a buzzing sound from the trunk rattling... Also... sell the infinity's and get something like memphis, or panasonics. :P

Speaker not working


Either. You can probably order a new driver (speaker, no box) from Mission, then put it in yourself. This usually involves 4 screws around the speaker, then disconnecting a coulple of wires, putting the new one in and letting the speaker bed in for a while. You've then got a working speaker, and a nice paperweight.

If you have more money, and fancy an upgrade, you can buy some new speakers. An odd one wouldn't match the others, so it would be 4 satellites and a centre required. The subwoofer should be fine.
