horns just add to the hi's...dont need any more hi's...need vocals but 25/35

The tweets are louder up high. I like the way they sound there...The vocals are also louder with them up near the windshield. Problem with turning off the bass was I did that....the speakers sounded a hell of a lot better than the ones I just took out. And a hell of a lot louder, so I was like "niceeeeeeeee...finally" then I turn on the bass, crank it up, and they get drowned out with the rap. Its only rap though when im really pounding...but I have to get something that will keep up ALL THE TIME, not most of the time. Barely getting the job done isnt enough for me. I want my front stage to shine all the time...
I just talked to someone with my same setup...Except he has a different car/different power, but same subs...he said his bostons keep up with no problem. Someone else just got the Pros with his 2 15" MT's...he seems to say they keep up great also...so i might sell these fairly soon. Plus my gain is like .6 from being all the way up, and once again...just like my last setup...i dont want to have to run my amp at full gain. I cant drop the speakers to 2 ohms ebcause they are 4 ohm speakers...

Didn't you say you had the tweets attentuated -3db? Turn that off, first of all. Ta-da. insta louder.

Oh my goodness this is easy.

First off, RUN YOUR FRONT SPEAKERS AT THE OHM LOAD THEY WERE DESIGNED FOR!!!

Second, RIP THEM OUT and put in Pro60's... Are you kidding me you want loud and you havn't bought them yet? You HAVE enough power, run them at their 3 ohms!

I have a mid 140's daily driver and the Pro60's ABSOLUTELY handle it... With only 150 watts I had to use 6 layers of deadening to dampen the midbass...

You know what you need to do...

He's gonna get the pro60's and have the same 'problem' if it's a configuration issue. My bet is that the gains simply aren't set (identically/balanced) correctly between the subs and comps...thus, the subs get loud way before the comps do. If the gain on the subs goes down, you just turn the overall system volume UP to get the same amount of bass...but with more mids/highs. While i haven't heard MBQ's QSC line in person, i have a hard time believing that they can't get loud enough on more than 400watts of power to balance 2 12's. If they can't...i find them a rather pricey set of speakers for what they deliver. (unless those 2 12's are ungodly *** 12's on 2500w in ported enclosures yadda yadda in which case...well..buy more speakers.)

I have the comps running off of channels 1/2,...and there is no way to turn the gain up for just the mid and just the tweet...they work together....The picture in the manual for Bi=amping them still shows the crossover controlling one side (mid and tweet) to channels 1/2, then the other crossover for the other side to channel 3/4

The bass doesnt get way louder than the comps EARLY either....they are both at about their max at 25. I dont want to make it that 30/35 is my max because ive heard that its easier on your head unit if its not getting cranked at full volume...unless it doesnt matter since the speakers are on an amp anyways... 2. I dont have 400 watts of power...i have 165x4. 3. they are running at 4 ohms...there is no other way to do it.

im just not gettin the bi=amping process....someone said this allows you to control your tweets on one channel, and your mids on the other...but how does this make sense, unless you wire BOTH tweets to 1 crossover...>going to one amp input, and the other crossover with just the mids, going to the other amp input.

I really wish someone who knows this stuff lived near me...unfortunately they are just all into the bass alone, and dont care much for front stage.

Im just worried to take it to a shop around here to do itbecause A...most of them dont carry MB Quart...B. I dont want them to turn the bass down and be like. "ok, we fixed it" cause that is what they will probably do.

The crossover has attenuation for the tweets. You mentioned in your first post here that it's set to -3DB. That means you can adjust volume on the tweet independently from the woofer. If you are running the comps off of channels 1/2, what are channels 3/4 doing? Did you bridge the amplifier to 2channel mode?

165x4 is 660watts...well over the conservative 400w i said you were probably using. Incidentally, you just said you are only using channels 1-2 but in this paragraph you say you are using 165x4. If you are only using channels 1 and 2, you have 165x2 - 330watts (max). Your HU can handle preout outputs of 30/35 no problem; it's not acting as an amplifier when you only use it for preouts.

My germaniums are running on a 4channel amp in 2channel mode. I have one channel running to one crossover, and another running to the second. If i were to run 2 channels to the same crossover, i would be able to send one to the tweet input, and one to the woofer input. Thus if i adjusted the channel going to the tweet input, i effect the tweet. If i adjust the channel going to the woofer input, i adjust the woofer.

Unless the point of the speakers is to sound good, not just get stupid loud.

According to those who have these speakers in setups ~140db (claimed of course), the mbq's should keep up. I am of course basing my advice on the assumption that these people who own them and claim they are loud enough are correct.

no no, sorry, you misunderstood me. I am only using channels 1 and 2...which is just half the total power thats available...UNLESS i was running 2 comp sets...I could use channels 1/4, or 2/3...but with only 1 comp set you can only use 2 channels.

The xover for the tweets can be changed, but not on the amp I dont think...REGARDLESS...the tweets are louder than the mids right nowanyways...and the mids are still kinda muddy.....

Im goign to go to maxxsonics friday and see if this guy i talked to can help me out...hopefully the problem will be resolved. Thanks for all the advice guys, Ill get back with an update.

If set up properly (i.e. proper high pass on the set), they should get loud...but I honestly doubt they truly keep up with that level of sub output. I owned the set myself; very nice sounding set although I didn't use the passives and ran them active.

Swithing to Boston Pro's isn't going to solve your problems.

Your amplifier can't be bridged into 2ch mode? (2x300 or some such?)
