Kenwood KAC-929

Be sure the RCA cables are attached and in good condition.
Be sure the remote wire from the deck is hooked up and good.
Be sure the GAIN control is turned up.
Volume on head unit is up. Make sure BASS options are not turned off on deck.
Be sure wires are going the right way. + to + & - to -
Loose wires in the box. Make sure subs are hooked to the terminals inside box.
Check all fuses on amp to determine if 1 or more i blown.

amp works no sound bmw 1998 740i

You could but the only problem is even if you ran the speakers in parallel, meaning + to + and - to -, the best power you would get out of the amp is 230 watts per channel. Would probably make your 6x9 sound good but not enough to push your 10's.

Its not pulsing, its called clipping. The sound is being clipped due the amp being pushed past is power capacity and distorting the signal. This will damage your speakers very quickly. No amp should be turned more then 3/4 up. If its not loud enough you need to purchase a larger amp or be comfortable with the wattage it produces at 3/4 volume. You may also have speaker wires touching/crossed causing th issue.

unless you are a technician do not mess with the amplifier.
it takes years of school to learn electronics. unless it is a blown fuse or something simple,you will never fix it.
i did kenwood warranty for 8 years and the amplifiers are difficult to repair.

Hello Spicer_kyle6,

Possible problems: 1) No output from the head unit. Try a different set of preamp outs. 2) No input to the amp. Check the RCA's and make sure that they are good and coming from a functioning preamp or subwoofer output on the head unit. 3) Input gain turned off or down too low. 4) Speaker wiring shorted, grounded, or open. Check all wires. 5) Speakers defective. Connect to a known good output to test. 6) The amp itself could be defective and still show a power-on indication.

Hope this helps.

HI DUDE UR REMOTE WIRE FUSE IS BURNT .... REPLACE IT ... AND UR SPEAKER ... OR SUB TAKES LOT POWER FROM AMP .... ....

Check your speaker connections... try using a multimeter set to "OHMS" and see if the speaker is reading around 4-8 ohms... if it shows no reading there is no continuity in the coil of the speaker

if you see that happen you might need to your i c sound chip or your trasistor change then and check

you need to check your wiring and check your rca wires to see if they are giving your amp a signal to put out
