Car speaker distortion at high volume
|
New member Username: Sqlover1Post Number: 1 Registered: Oct-09 | 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 |

I see you really had no valuable contribution to add to the conversation. But nice work on the lecture makes alot of sense when you don't have a point. Bottom line is the speakers need to be amplified, head unit power is garbage if you wanna have good sound, plain n simple. |

Bronze Member Username: Will4992NC Post Number: 79 Registered: Mar-08 | I hope you didn't just refer to Jensen as something high quality. They have some of the worst equipment I have ever seen. If you wanna turn this into a pissing contest, I'm pretty sure my Alpine, DLS, Seas Lotus 350 will sound better than anything you have. I'm also pretty sure my DD crx is louder than anything you have. And steve my hometown hero f@g, i wasn't even referring to you. I agree that an amplifier is necessary, but I would invest in some higher quality components. |

If you wanna compare to what I have for system, you can take your pick I am willing to bet both of mine are far better than yours LOL. My riv's system alone is 6000 watts on a single 12 woofer. Throw down a list of what you got in your rides . I'll do the same, we can have a pissing contest F@G. First you have to remove your wiener from that other mans @$$ so hussle up. |

Gold Member Username: Van_manBoston South, MA Post Number: 5178 Registered: Mar-06 | wow. Where to start..? Ok, as far as the speakers sounding like junk at higher volume..First the speakers are distorting due to poor signal. An Amp can help deliver a clean signal, as can a better HU. Now A speaker amp should have at least 25 watts or more to sound clean with that speaker set up. However, I bet you will get a budget amp, max out the gain, blow the speakers and be in the same boat. I suggest doing a little research here, http://www.bcae1.com/ Then posting a budget of what you can afford and ask for suggestions for a decent entry level amp. Then figure out how to set the amp up. |
