Need help bad. Kicker upgrade gone wrong....

Hey all-

I replaced all four of my factory speakers today in my Quad cab with Kicker DS600 6" rounds. They were suggested to me by the folks at Crutchfield, and were supposed to have a great sound, much better than stock. I do not have an amp, but do have a JVC KD-HDR1 head unit. Unfortunately, after the install, my truck sounds worse, I mean much worse than factory. No bass range at all, and little mid. All that is really audible is treble.
The only thing I can think of, unless I was just very mis-led on the speakers themselves, is that they also promoted these foam baffles that tuck into the speaker hole which the speaker rests in. The rep at Crutchfield said that they protected the speakers. Is it possible that these are allowing the speaker full motion?? Can these speakers really be this bad??

Any help is appreciated.

Ryan

recheck the wiring polarity if you have crossed polarity you will have no bass, also if you have crossovers in the head unit make sure they are off, they are intended for external amplifiers

also the foam baffles are great if you use an amplifier but you do not need them for coaxial's off a head unit

Thanks Sppb. I just got off the phone with Crutchfield, the rep said cut the back out of the foam. ( Waste of money ). He also said tham my JVC Head unit might not have enough umph ( 20W RMSx4 - 50Wx4 Max) to power the Kickers sufficiently. Is that true?? I was not really looking to put an amp in, I just wanted a little better sound, and a bit more bass.

Did I screw up? The Kickers are recommended for Max RMS of 50 whatever that means.

Thanks again.

Did you check that? There is a + and a -.

I have an awesome 4 channel amp that would be perfect for what you need. It's a JL Audio e4300. Puts out a conservative 75 watts x 4 and that is not peak. Has a small scratch on the face bur it works great. Looking for $185 shipped.

I also think you are wired out of phase (reversed polarity).

Guys-

The speakers from Kicker have a large prong (positive), and a smaller one (negative). The folks at Crutchfield provided wiring adapters that attached to the speakers, then to the factory Chrysler speaker plug. I installed them per the directions. I suppose they could be incorrect, but surely the odds would be against that, no?

Anyone happen to know which wire in the doors are positive and which are negative? Does anyone have these speakers??????

Also.... I forgot to mention that we broke the book out on the JVC head unit, no matter what setting you elect, the speakers have no noticeable sound in the deeper frequencies. And they break up when you crank the stereo up past 35 Db.

Can anyone explain how the addition of an amp would remedy the situation??

As always..many thanks for all the advice. I will try to verify the polarity in the mean time.

I did a little research on does Kickers and you don't really need an amplifier for them, 9-50 watts rms but the frequency response is 43 Hz to 20 KHz so below 40 Hz they got nothing, you might need a subwoofer system to reproduce the low frequency or get some high efficiency 6x9 for the front doors
