Ok, so I'm new at posting stuff but I've been using this amazing website for a few years now since I bought my 07 tl.



Just got an A spec lip kit painted red and installed this week. Now I'm not audio expert but I'm not completely out in left field I'm hoping the good people here will help me out. I'm not looking for overboard but anyway my dilemma and question is this...

I have a Rockford t600/4 amp. My mids are the pioneer ts-m650 pros. My tweeters used to be the alpine spr 10tws. They worked for a little while and I like my music clear but screaming loud. They eventually gave out and started to "crack" a lot. So I decided to try getting a Rockford 150/2 channel amp that put out 50watts rms per channel and hook them up to the Rockford t2t tweeters. Now it seems as if these tweeters maybe be starting to crackle. My gains arent turned up at all on the 4 channel or 2 channel.
I'm at a loss now... unsure of where to go next. Thought since the pioneers sounded good and got really loud, getting the 4inch bullet tweeter in the pro series and a little bit bigger 2 channel amp, and custom fiberglass a part in my door next to mids for the 4inch tweeter. But any help would be greatly appreciated

What 4" pioneer tweeter are you referring to? Can you post a link?

Also, with your last tweeter, I see you had different branded tweeters/mids....what crossover were you using for the tweeter?

Or the 3.5 inch ones. I used the crossover thay came with the tweeters themselves and attenuated it -6 or -4 cant remember which is lowest

Bullet tweeters, huh? Not exactly sound quality oriented.

What crossover are you running and is it the one that came with them? You can't just switch speakers on a passive crossover, if the resistance is different, the crossover point will be different.

Im using crossovers that came with the tweeters yes. I tried matching rms ratings to speakers. Tweeters handle 70 and i think the amp puts out 50-60.

Oooorrrr. Gve me recommendations on a 2 channel amp...set of tweeters and ill jus buy that. You guys are the advanced gentlemen here

ajgray04

My knowledge is not entirely....@$$ backwards is it? I matches rms ratings from amps to speakers. My gains are set to 0 and the rear speakers and front mids sound great. I can turn my head unit up to 40 and they scream, to me sound amazingly clear. As if they easily handle a little more. But i didnt think turning up gains was any good really if i matched rms ratings closely.

You might be looking at it a little different. Mine is a SQ system and with that in mind I try to have more amplifier power available than the rms rating of the speaker. My midbass in the doors are rated for 180w and they're getting 300w each. The average power is still going to be way lower than 180w but I have enough power available for the transient peaks to get a life like and very dynamic sound. Your amp can be rated for more than the speakers average rating and you can set the gain to cut back on the power if need be. You absolutely don't have to match rms ratings, more power almost always sounds better even if you're not cranking them up that much.

It would probably be a good idea to look up the common ways of setting the gains. The gain knob is not a volume knob. You could have a low level input signal into the amp with the gains turned all the way up and still not have as much power to the tweeters as a setup with a high level signal input with the gain all the way down.

I would try to find out exactly how much power the amp is putting out. Under powering speakers won't hurt them except with tweeters. There's some debate to this but some say when the amp clips on a tweeter through a passive network, it's similar to sending a full range signal. I don't know how much of it is true but if it is true, you would either need to turn the volume down or run a more powerful amp. I've never had a problem but I have 150w available to my tweeters so it will damage my hearing before it damages the tweeters.

Marine speakers. Seriously.

It sounds like you are over-driving the tweeters.

I hate cars. What type of tweeters do u have. There rms rating compared to what amp and its specs?

I hate cars

Dynaudio Esotar 110. I'm running 150w and they're rated for 150w long term and 1,000w 10ms. The only reason I'm not running more than the rms rating is because it's already high for a tweeter and they're pretty efficient so I have the head room I need. I cross them over at 4khz or higher usually so they probably do not see 10w on average and that leaves me with enough left over for the peaks. I have run 150w to tweeters rated for 75w with no issues but again, average power was likely very low, well below 75w.

Your issue could very well be too much power or it could be not enough or something somehow is wrong in the crossover dept. Underpowering causing speaker failure has been proven all but impossible. I just remember something with underpowering tweeters in particular that it's possible if the amp is clipping, particularly on a passive crossover. Maybe the experts can reject this idea if it's wrong and you're simply overdriving the tweeters.

I hear alot about dynaudio on here. Mayb i should just buy those tweeters and a different amp?

I hate cars

They're next to impossible to blow but they're not the best bang for the buck. They're some of the best tweeters out there, some consider the Esotar tweeter THE best sounding tweeter but you can get something that sounds 80% as good with decent power handling for 1/10th the cost. They also don't come with crossovers unless you buy them separately and I believe even the crossovers are $300-$900 depending on which ones you get. Active would be the best bet with those.

I would definitely try to get to the bottom of it before installing new tweeters, you wouldn't want to blow another set.

ajgray04

With 2 channel amp hpf xover as high as it will go. Xovers installed that come with tweeters. Gain at 0. Im
Unsure of what could cause it. What control unit do i need to actively crossover speakers?

ajgray04

Literally at this point, i want something thats very loud and sounds good, and im willing to say, i hate cars, tell me what xover, set of tweeters and amp to buy lol

^^^What is your budget? I would highly consider buying a set of matching components. This will ensure the crossover is compatible throughout. I am a dealer for many brands. PM me if you would like.
