Need Help Before I Purchase.

Not only did I spend time tuning this amp, I've had two different stereo technicians tune the amp, speakers are still pitchy. Like I said, not real bad, But I know speakers like Alpine and Infinity can sound smoother(A little calmer on the high notes) And trust when I say this, Tuning the amp is what should do the trick. My gains are barely up, My HPF nobs are a little pass the middle, any less, speakers will distort. Both channels are on the HPF setting, Full range will distort them. I'm running all coaxials.

with the cheaper head units, lowering the treble will just destroy the music quality more then helping with reducing harshness.

Harsh sounds can be caused by the 4 mids and highs amp clipping from lack of amperage/current or even a bad ground. The other reason is with a head unit with cheap internal sound processor. Grab a sound quality oriented head unit like a pioneer 80 prs, alpine 149bt or kenwood kdc x998 and you'll naturally a lot cleaner sound without as much harshness and if anything you can easily lower the frequency thats causing such harshness(usually somewhere around the 5khz-8khz.) with the head unit's built in parametric equalizer.

You'd be surprised what wonders a good head unit can do to your sound system.

Way back then when i had a pioneer 4200ub, i had the worst time doing everything i can to get rid of harsh sound from using high quality lossless files, to using bright sound condensors, to putting tweeter input to -18 db on the passive crossovers on the components, to completely treating/deadening the doors and went through many sets of speakers along with positioning tweeters in every possible location. It either sounded bad because the lack of top end or it was still harsh. After I changed to an 80 prs all those problems went away and almost any speaker sounded good in my car even tried poorly compressed mp3 files and they still didnt sound too bad.

Thanks for the reply bro. I'll definitely check the ground and speaker connections first, if thats all ok, I'll look into a better head unit. THanks Again. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Try reversing the the positive and negative on the passenger side tweeter this helps more often than not.

if your head unit doesn't have full active crossover, you still can use passive crossover to get much better value frequency every each speakers.. for the mid hi you may use bi-pollar capacitor to cut off the frequency to get more soft sound from it.. the most important is tuning..//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
