So yes I mounted them to some wood baffles as opposed to the junk plastic OEM piece. And put some deadener on the door. For some reason I am still lacking some midbass. More than likely its my tuning. I've got the HPF turned on at about 60 hz. Should it be set somewhere else?

Have you sealed up the doors completely, so that no holes are present? That helps tremendously.

theres some small holes but they are inevitable holes IE wires going through door, mounting holes, my doors use these nifty plastic hook looking deals to mount to the door. Shouldnt they have some midbass regardless of the door being completely sealed?

Make sure the baffle is firmly placed against the door. you may also want to put some deadner between the baffel so no air leaks are present. Clay works aswell. One thing to also check for is that the comps are wired in phase.

Alright I am slightly a noob. I have the speakers wired with the biamping inputs. The tweeters are running off of the front channels, and the mids, off of the rear. Both filters are on the HPF, 60 hz. Surprisingly, I love the sounds of the tweets at this range, and still have a little tuning to do to them. What freq should i set those at? The mids just werent making enough midbass for my liking. The monsoon in my ta has some subs in the rear sails, they make good midbass, so it is sufficient, was just looking to get a little more out of my germs.

there is something very wrong with that setup.
couse ive heard notting but good things about the Germ.
I went to shop near my house and listen to the Germ in some guys car and i really liked it, and he was only feeding them 75W each side.

I didnt say it didnt sound good at all, the hype of the germs is ALL its cracked up to be. This thread is basically geared towards where to set the tuning. I did some more tweaking today through the crossover itself and it helped tremendously, I made this thread in an attempt to be lazy, and get answers easier lol overall, the germs get an A+ x 100000. I love them, well worth the 450 dollars.!!

how much are you feeding them? also did you try bumping the "bass" (not sub) part of the eq on your hu?

X2 how much are you feeding them???
i plan on feeding my set 200W each side

jbl px300.4, rates it at 114 watts per channel, each speaker, gets one channel, so approx 230 per side, realistically probably 200 or so i would say. I love the sound of the tweeter, and Ill play with the internal eq more tomorrow when I wake up, working midnights ftl lol

I run AA poly mids and they had little midbass at first, but bumping up the bass EQ to +6 brought them to life.

Hopefully that's all your missing is some EQ'ing....

+6...wtf? I'd never do that. My germs run completely flat on my h/u and they sound **** good, even though they are only getting 120 per side.

shouldnt be a problem. with them at all. i have four and love em, and im a happy consumer. if you seal the doors the output is considerably better. CONSIDERABLY. i use a set in the kicks and those in the doors are pretty well sealed. if your patient enough with a heat gun and plexi you can get a **** good panel to close up your access panels and dynamat over them to make the speaks as airtight as possible. tuningwise, theres alot of options on there, i cant remember what mine are set at (been overseas a year) lol. good luck.

quick question.... you arent talking about the settings on your amp correct ? the germs come with cross overs that you should be using and you should give them a full signal. The cross over will take care of the rest...

yes but i still need to set my hpf at a frequency, and it will affect how the sound is reproduced.

try it out man. thats what car audio tweaking is all about, trial and error.

I'm surprised nobody has picked up on this. This is your problem. Turn off the HP xover to your mids (rear channels I'm assuming, correct?). You are killing any midbass signal before it even gets a chance to get to your mids.

Well my AA's are only getting 60 per side ;) And actually I've backed it down to +5 as I checked at lunch today. I mostly listen to 80's rock/metal and that's where they sound the best. Drums have MAJOR impact and that's how I like it...

well Ill be ****ed lol I will do that for sure, should i set a LPF? or just have it off?

Just turn it off. The xovers will take car of the LP xover for you, it'll be a higher freq. than the amp can most likely take care of anyways. Might as well turn both off, in reality, as somebody mentioned before, the passive xover is all you need, but the HP to the tweeters isn't necessarily going to hurt anything.

Yep, I say just turn off the amp crossovers. The passives will take care of you.

hm Ill have to give it a try tomorrow. I just now got everything buttoned back up as far as door panels and such. Its a pain but its worth it in the long run.

you got the germ from Don right??
you should talk to him about it

If none of the above suggestions work, switch the phase on the passenger side woofer. The midbass will either drop off or increase dramatically. If it helps, keep it that way, if not, switch it back.

i caught it and told him to not use xovers on his amp already on the first page... dood doesnt understand tho....

maybe they should be tested in another car...hmm... perhaps you could send them to me so i could...indefinitely borrow them?

The passive crossovers that come with the Germaniums do two things
(a) They high pass the tweeters (@ 2.2 or 2.6khz)
(b) They low pass the woofers. (@ 2.2 or 2.6khz)
What they do not do is high pass the woofers. While you can run the germaniums full range without any high pass crossover, i would not push the volume too extremely with that setting...a 6.5 inch driver simply gets jacked when you start trying to tell it to play 20hz to 2500hz. 63hz/18db is probably fine, and i ran mine @ 80hz/12db high pass. I eq'd up slightly on my (ghetto *** un-deadened and no baffle) install at 120hz and 200hz. I don't think the highpass x-over @ 60hz is the problem. Midbass is at least 80hz+...all the way up to ~200-250hz. Unless your high pass crossover is something extremely shallow like 6db, it should simply be doing what you want - cutting out bass so your sub can play that while your 6.5's play midbass and midrange. I've played my set without any subwoofer for a while and they produce a surprising amount of volume @ 60-100hz considering their size... they merge very well with my 12w6 (poor 12w6.)
