Kenwood KSC-SW10 not enough...at all

bigaudiofanat

Ya I would even care to say there may be a problem with it. May want to call for a warranty replacement. Because I know personally it produces plenty of bass over even aftermarket speakers.

I really don't want to rule that out.

I was initially thinking it was broken from the start, because I really couldn't see how a company could release this and market it as useful. Im going to call onlinecarstereo and see what they have to say

It sounds like 2 things are wrong:

Maybe the 180 degree phase-inversion button is pressed, which really only helps songs with mid-bass hit but ruins anything with low freq boom or bump. Make sure that is off if the speaker is behind your seat.

Also- You said you "turned the sub output off to test the door speakers." I think it should be wired like a normal speaker, it's hard to do it successfully without filters if you are using a preout, and they don't recommend any preout with fader. You may be throwing too much amp'd sub sound at it when it expects relatively normal sound that it can convert to bass. IMO you shouldn't double dip with these powered subs!

What is your per-channel output on that Pioneer? I kept stock head and amped the DB6501's with 50w to each side. Big set my amp gain to "stun but not kill" with stereo full blast, and it is plennty, even with windows down going around Willow Springs at 80-140mph with Beastie Boys (RIP MCA!)

I've tested both ways with the inversion button pressed and not.

When I say I turned off the subwoofer, I mean on my HU it has subwoofer out via RCAs. This allows you to disable the sub out so nothing goes out to the sub.

Here is the spec sheet for the HU:
AVH-P3400BH - <b>NEW!</b> - 2-DIN Multimedia DVD Receiver with 5.8" Widescreen Touch Panel Display, Built-In Bluetooth®, and HD Radio™ Tuner | Pioneer Electronics USA

So are you saying this amp/sub shouldn't be using RCA out from the back of the HU? I'm not sure why it would make a difference if it was wired as a speaker instead as opposed to RCA out. Maybe I am confusing what you are saying here..

i assisted in installing the gear into his car. first lemme answer your concerns.



1. if the 180 button was pressed, bass would sound hollow, or out of phase, hence the button being a phase button. this is not the issue.

2. i have used preamp outs from head units for years while using their built in cross over properties with great success. works fine for us average joe enthusiasts that want good sound without a ridiculous amount of money invested. the headunit spits out amplified sound straight to the door speakers, and they are crossed over with a 12 slope cut at 80 hz i beleive. the sub was set around 80 also, phasing was played with but didnt matter in this scenario.

heres the problem, its one damn amplified 5*7 driver and one passive 5*7 driver. you realize these are like having a 6.5" sub. hardly much punch in the world of "QUAD" lol. hell, if they coulda been at least 6*9 thats like having an 8" sub.

the kenwood unit i am sure works very well as a filler sub. when i turned down the volume on it and just let it fill in the bottom it did do it, and for some this is fine. well if it was mine, this thing is a joke. i have a 12w6v2 in my car and a 10 in my truck. i would never switch to this sub unless i decided i hate bass in my music.

it cant handle what the poster wants, and thats the problem. hell, as i was installing, im like only a 10 amp fuse? and why this rinky dink thin gauge wire? but it all makes sense, its not much power, and not much speaker area, so obviously its not much bass.

hope this helps for those in the future looking at this option, my recommendation, hear it first before buying it.
