Hi everyone,
I have a sound distortion issue (at mid to high volume) with my car’s speaker. currently I have a kenwood ( KDC-MP336AXS) head unit in my car that gives me 22Wx4 RMS out put.
I connected it to 2 pairs of 6.5” speaker, my front speaker: Kenwood( KFC-E1662) 35 W RMS @ 4 Ohm and rear speaker : JVC (CS-V625 ) 30W RMS@ 4 Ohm.
I set the head unit bass setting to zero to have less pressure on speakers at high Vol, but when I turn the volume up to 25 (max Vol =35) the speakers sound distorted !
I also have a new Polk Audio db651 60W RMS @ 4 Ohm which I’m gonna replace with rear speakers .
My question is, what causes the distortion and should I buy an Amp for my Polk speakers ?
Anybody with good experience can help me plz?
Cheers guys |

man, I'm having a similiar problem. my rear speakers started crackling, but they were stock so i just figured they blew and needed better ones. so i bought the cheap sony xplods and after the 1st 10 mins they started crackling, BUT ITS ONLY AT HIGH VOLUME. so obviously its not the speakers themselves, its a wire issue i guess. but how do we figure it out? someone HELP US 0UT!!! |

Whats the THD rating on your head unit? I think kenwood is like .008 THD on their decks so it is probably a wire issue. I would definately suggest amplification on your POLK's. |

Normally the amplifier should have a better or more RMS or wattage handling than the speakers, also on the other hand the impedence rating should match with the impedence rating on the car deck, what happens is that when the amp reaches its power peak, it goes into distortion for either of these 2 reasons, hope this helps. |
