System in, not enough mids. Suggestions?

[NOIRtist 10+ year member]

No pix yet, the system is in, but the car isnt totally reassembled. And its in shambles. lol But Ive been testing it out and it sounds great, however, theres not enough midrange in the sound. I've messed with the HU EQ and still not getting what I want.

Heres my setup:

- Diamond Audio D661a Component Speakers up front

Specs: 6 1/2 In., 100/200 Watts

-Alpine MRV-F345 Multi Channel Amp

Specs: 4/3/2, 75 RMS x4,

*** Actually I have a temp amp, a newer smaller Alpine, the MRP-F250 powering the front speakers while my other amp gets repaired. **

- 2 Alpine SWR-1022D (10") Subs

- Alpine MRD-M1005 Mono Amp

- Subthump Dual 10" T-Top Box

Now, my questions are... is it possible the amp isnt providing enough power to the speakers? (We didnt bridge it.) Or that the amp itself could be adjusted to correct this? (I'm really thinking its amp related) Could some lower frequency sail panel (rear) speakers fix my problem if its not the amp? Could it be a power issue? (Yellow top going in, alternator more than likely in the future.)

Any help would be nice. The components are naturally brighter sounding, but I've heard them before and I dont remember them lacking this much in the mid range. So I'm at a loss.

Thanks.

ok so let me get this strait you have the d6 components and you think they are lacking in the mid area. So my D9s are rated at what like 150 watts and I push my us amps 1000x that will do 300x2 at 4 ohm clean I usualy push around 200-250 to them at full power. I think you could easly give those components 150 watts or maybe 175 if you were to 1 deaden your door that will make a AMAZING difrence there. Make sure your highpass on your amp is set high enough and not to high and I would put that amp to them bridged at minimum. Just make sure your not clipping your signal or they will blow with 150 watts of clipped power. What tweters do you have the metal or silk dome. Not sure if you adjusted the tweeter x over adjustment in the x over too I know my d9s you can adjust it up and down like 2 or 4 db. I would run o guage or 2 guage to the back and use a distro to the amps. That or 2 4 guages one for each to the back not sure what you have might not be getting enough power though I doubt it.

DEaden and give it adiquite power adjust x over for tweeters.

Sometimes putting the midbass in a sealed pod within the door or in a kick panel may give some more higher frequency midbass punch, along with higher power handling and no chance of rain hitting the midbass. This will also keep road noise from transmitting through the woofer cone, reducing sound deadening demands inside the door cavity. Beware though that most component woofers are designed for free air and may not sound right. This is why some people use home audio drivers in small sealed enclosures. Within a small enclosure as such, you could also use polyfill or spun acrylic thread to controll midrange resonance problems as well.

diamond is a spicific I/B driver acording to them I wrote them and asked when I was going to make my kickpannels to see what there sugestion for sealed enclosures were.

The crossover freq is set at 75. I'm going to mess with that a bit. Also, I have the aluminum tweets I believe. The speaker is somewhat sealed due to the original location, but not air tight by any means, just well confined. If I cant seem to figure out any other way to fix this, I'll get with the sound deadening.

Now, what exactly do you mean when you say clipping? Distortion in the audio at higher volume levels? I know what clipping is in recording references, but I'm not sure how to find that in this specific application. And I cant really tell, but are you suggesting that I bridge this amp?

I'm trying my best to figure this out, but unfortunately I really do lack the experience to troubleshoot a system. lol There's a lot to know. A friend helped me the whole way through, so I more or less just ran wires and did what I was told. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Thanks for your help guys, I hope to fix this soon.

To me with yoru first post it seemed as if your using 2 channels on a 4 channel amp to power the components if you were to bridge the amp it would have about 150x2 @ 4 ohm like you need. Clipping like you were thinking is the same as what I am talking about most decks will strart to clip before the volume is all the way up and if your clipping your amp by having the gain up to high to start with is a sure way to blow the components up. I think alot of why the highs seem harsh is because they are aluminum my silk doams with my d9's are clear and get louder than alot of the other components I have herd.

actualy the most you will get with that amp is 100 watts to each channel bridging it so it is a 2 channel rather than 4 that little amp your running right now using just one channel on each is only 40 watts thats why you have no mids if your using it that way

I thought that it was underpowered and my friend said it wasnt. I'm glad thats cleared up. I just got the yellow top in so im going to mess with it a little bit, see what I get out of it. My other amp should be more than enough to power them, but this little one needs to be bridged to give them proper power correct? And is it possible to damage the speakers by underpowering them?
