Default is it safe to do this?

ive got a set of polk momo 6x9s. ive found the tweeters on them are too overpowering when ive got the speakers cranked up.

these speakers come with crossovers, and leads to both the woofer and tweeter. is it safe for me to just pull the tweeter leads and leave the woofer connected?

Safe? Should be. You will be missing a lot of information from the music you are listening to, from likely around 3khz and up (most of the upper meat of the vocal range and cymbals etc)

Any adjustment on the tweeter crossover? Adjustment to turn the treble down on the HU? Pulling the tweet altogether would hopefully be a last resort type of fix, but too harsh is too harsh.

ive got everything set from about 3k-20k at -6 on my HU, but with these things being just inches from my head, its too much. and no, no tweeter adjustments at all in the crossover.

It's not necessarily a volume issue, but probably a distortion issue.

i turned the gains down quite abit and that solved the issue.

now what would be causing the distortion? the speakers are rated at 100wRMS, with alot of people claiming to be pushing 150wRMS no problem. where as im not even running 50wRMS to them, im running these off an xtant a4004, 50w x4 @ 4ohm.

Generally you want to maximize your HU's clean signal output, and minimize your use of the "gains" on the amp. As a general rule, set your HU to between 75 and 80% of max (IE 27/35), and then work your gains up from minimum to your desired "max" listening level while listening to material that you know VERY well. This IMO is the easiest way to get in the ballpark with your system settings.

One thing, you may desire more output than your system is capable of playing back without distortion, 50w is usually enough for most people. but if you are asking for 50w from your amp, and the music contains some transients (louder notes, cymbal crashes, bass notes) the amp will clip and the playback will distort.

Amp power is a lot like horsepower, you really cannot have "too" much

Generally you will get more distortion running 50 watts and trying to get what you want on "100w speakers" than if you ran 200watts to them.

Just like Fej said.

i was talking to the polk guys today, and spent some time playing around with my system. its loud as hell now, and very clean.

ive got an alpine head unit, and i was setting my amp to it at a setting of 27. that was causing some distortion. i knocked it down to 25 and upped the gains, and it was very clean.

i also bi-amped the 6x9s off my xtant a4004, which helped a ton. and, while i dont entirly like it, i ran the 4x6s off my head unit, a cda-9815. one of the big V-link ones with the actual rated 27w RMS x4 channel.

so, everything is clean, loud, and easy to listen to.

The 9815 actually has a lot of features IIRC, did you say bi-amp as in 2 channels mid/2 channels tweet or just bridging the 4 channels into 2?

Sounds like you are a lot happier with the system, enjoy!

the tweeters are running on 2 channels of the amp, and the woofers are running on 2 channels of the amp.

and yes, the 9815 has a TON of a features. time alignment, bass focus, 5 band parametric EQ, and a ton more i cant even remember off the top of my head.
