Full range or high pass on comp sets?

[Troydb 10+ year member]

The amp being full range wouldn't blow the tweeters, as the passive crossover is what highpasses the tweeters. But yes, you want to highpass the component set as the passive crossover doesn't limit the low frequencies being delivered to the mids.

But if you blew both tweeters, it means you did something wrong. How did you set the gain for the amp ? What amp do you have ?

What about someone like me who has a Monitor 1 amp. It does not have a crossover on it. I want to use this amp to power a set of components running them off of their passive crossover. But, like you said, the amp would be playing at full range since it does not have a built in crossover. What should I do? Thanks

does your deck have built in crossovers? i'm not using the crossovers on my amps, i have all my control up front on my head unit. i would rather have it right in front of me anyway so i can change a setting w/o moving an inch.

yeah it is an Alpine 9830 and it has a built in EQ. So just run everying on full range and adjust it at the head unit?

yessir. set the crossovers at the head unit, thats what i am doing and i think most people are doing.

yea maybe I shoulda of had someone done it for me..but that would defeat the purpose of me tryin to do it myself..i do this as a hobby. No i dont know everything and i know that..Thats why I ask questions on this forum..I switched over here from Roe thinkin that maybe the ppl over here were maybe more helpful and less bashing all the time...Insted of gettin any answers to my questions ppl just talk down to everybody and try to make them feel stupid...ther are helpful ppl but im gettin to the point where im not even goin to ask anymore questions bc im sick of getting talked to like a 15 Year old...yea my tweeters blew...they never worked...and now im the dumbass..like i said the midbass sounds great, they handle every bit of the power i throw at them... all i wanted to know..can i have one side of an amp be ran at 2 ohms and the other at 4>? Also like i stated earlier there is no way that I am supposed to run this amp on High pass...if that was the case how would the mids have any bass output? Im gettin conflicting answers and i dont know what to believe..i guess ill trust my ears and when the amp is on full range the mids sound great and on HIgh pass they sound like tweeters. IF anyone can help me i'd appreciate it... I know that no one has really said anything to offend me but i see alot of this type of stuff goin on and i know it discourages alot of ppl from asking questions and learning, which to me is the whole point of this forum..Not a contest of who is the smartest car audio person.

I didn't mean to come off at all like that. What I meant was if you weren't confident in your wiring get together with one of us for an install day. I am sure one of us would be around your area. That is what i meant by "you shoulda got some help with your install". Shit, we do it all the time, all you have to do is provide the beer //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. Anyways, whether you had the amp on highpass or full range, as long as the wiring through the phoenix gold crossovers was correct there is no reason the tweeters should have blown. They do a more than adequate job of keeping bass frequencies for the tweeters. The only thing i can think of is that the tweeters weren't hooked up to the tweeter section of the crossover and that is why everyone was saying to check your wiring.

yea thats the thing..im pretty careful about those things and the tweeters were hooked up to the tweeter side of the crossover..when i noticed that the tweeters werent working i removed the crossover and took off the wires that were hooked up to the tweeter side..the mids kept on playing...i dunno..i never got a chance to listen to the tweeters at all and im disapointed..i ended up buyin a set of bnib infinity silk domes so we'll see how they do...i know they arent the greatest but I sniped them on ebay for 21 bucks..they usually are buy-it-now for over 50..im gonna just leave it at highpass and unbridge the amp.. everything will get 50 watts..unless the tweeter being 2 ohms gets them more power on that side of the amp.. and as far as ppl helping me out..i would love that..im from new york..just moved down here to nc and i dont know anyone...id like to meet ppl with the same interests....drink beer n shyt

Ok I tried turning on the HPF & LPF on the head unit, but there was a lot of distortion even at low volumes. The distortion was coming through the component set and not the subs. The comps are run off of their passive crossovers. The disortion only happends when the HPF is on. There is no distortion when the LPF is on and the HPF is off.

So, with the HP & LP filters off, the only adjustment I have is via the head units EQ. But that is only 4 bands which isn't that much adjustment.

Any suggestions on what I can do??? I don't have the money to go active. I just want a plug and play setup.

get an eq i guess...my mids dont sound as good on HP as thet do on full range..they dont move at all on high pass....i trust you guys are telling me the right thing but when I was readin about these comps i heard that mirrors were shaking and all that..with the hp pn this doesnt happen for me..with full range they get to moving...and they dont distort,...Im gonna have to meet up with some fellow north carolinians to fine tune my system...everything is installed it just needs some deadening and tuning

 

[tcguy85 10+ year member]

i have mine crossed at 63hz with a 12db slope and they do make all 3 of my mirrors shake. and it's deff my mids that are doing it and not my sub. when i turn the sub off they still shake just as much.

trust me, at high volume you do not want to play them full range with rap or hip hop.

i'm going to guess that you don't have a sub?

Yeah I've got two subs- 10" IDV.3's.

So what you are saying about playing them at full range wouldn't be a good thing? My component amp is a Monitor 1 amp which doesn't have a built in crossover. It just plays full range but the comps are run off their passive crossovers. Should I get a different amp or what? I'm not real sure what I should do. Everything sounds ok but it just doesn't seem to blend real well together.

why can't you use your head units crossovers?

BTW i was actually referring to the other guy who posted directly above my last post.

 

[skydeaner 10+ year member]

If when the crossover is turned on they aren't moving at all then you have the crossover set too high. What frequency are you setting it at?

Sorry didn't mean to jump in.

Does your passive crossovers have the +or- 3db switch on em where are they set at? Its for the tweeter. That could be an issue also. The Octanes I used sounded way better at -3 so...maybe.
