installed hertz mlk 165's and not impressed

[t-money 10+ year member]

they sound better than my kicker comps i had but not getting much if any midbass. I usually install everything myself but due to time and the weather i paid a shop to deaden my doors and install the hertz mlk's. I am running them with a audison lrx 2.500(200x2) so theres plenty of power going to them. They sound kind of hollow. What should i do now? i was thinking about calling the shop and making them check things over. Was i expecting too much from these components or what? just a little frustrated since it took me a couple months to put them in and now there not living up to my expectations.Should i stay at the shop and have them take my doors panels off and inspect their job. Its a shop that a lot of guys recommended to me but i just think something is done incorrectly.

i would check before you do anything else to make sure everything is properly installed

set your tweeters level down if it's too bright, make sure they run 12 AWG wire over your midbass, i ran 14 and it's doesn't have enough power going through.

Another thing is using a deflex speaker pad will help the midbass.

There was a pretty long thread about the mlks were people were running the same amount of power as you and said the same thing. So they put more power to them and they said they kept gettig better and better. I heard a set running 500x2 and they were pretty intense.

i've been told that the power i have is plenty. I have checked the amp settings and its fine. They ran 14 guage wire to the midbass, they said 12 guage would be overkill. Since i paid i think they should check everything else. I've done plenty of research and i know th ese speakers should have some killer midbass. I personally think its the install and thats shy i want to bring my car back to them

edit: the tweets aren't too bright, although they mounted them right beside the door speakers in the stock location pointed towards the dash

12ga speaker wire to the midbass's would be overkill. 14ga is plenty. speaker wire doesn't need to be thick like power wire to get the job done.

I would check phase to be sure they didn't wire one side up in reverse. What is the rest of your system setup/specs?

check the phase of all the mids, make sure there are no leaks in the baffle, also is the baffle solid? Recheck the Xover points and gain settings. As for the power, your amp should be more than ample to do the job, the guy who said put 500w to them is out of his mind.

so the op running 14ga instead of 12ga has to do with his lack of midbass

check the HPF and tweak the EQ settings if the physical install is fine...

yep, it is the new thing, 14ga has way to much voltage drop with 200w, you must use 12ga.//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Basically, I think as it seems others think it is installation error, mor than likely.

big wire is so overrated

12ga 10ft @ 200 watt = 196,86 watt to the speakers

14 ga 10ft@ 200 watt = 195.04 watt to the speakers... 1 watt is nothing

check phase

Wow, talk about inefficiency. I would never want to pick up a pair of mids and pay the price they are if you need to give them a ton of power. My Zapco CK-16.2's were hooked up to a PDX 4.150 but the gain was literally set all the way and they had pretty good midbass just like that. I'm sure if I turned the gain up I would have noticed much better results but if that 500w is true and if 200w isn't doing it then I would find another pair of mids.

i was thinking they may have wired the mids out of phase. If i switch the + and - on the amp will that fix it or do i need to get at the crossovers to fix it. I just don't beleive i'm getting the midbass i should with these speakers.I turned up a song and they just sounded terrible, i thought i blew them they sounded so bad. So so i need to get at the crossovers to change the phase
