One thing I havent seen in this thread in regard to good midbass is install quality.

Just as a sub box can make or break a sub's output, install can make the same difference in midbass reproduction from full range setups.

The lower the freq the more important an enclosure becomes, which is pretty evident in the OPs setup having a serious lack of midbass.

Reinforcing the door, sound deadening, & sealing is mandatory for midbass. Google or search on here about an "Infinite Baffle", as that is basically what you will be turning your doors into.

A lot of good info in here about setting crossovers, but I think the install really needs to be squared away before tuning the "finer details".

Hopfully i'll be getting to the install part soon. I've learned alot from the members here, read countless threads on same subject. Im also researching moving the mids to the kicks, or sealed door panel pod with the 8" midbass driver, or IB in the door for either of those... Im doing as much research as possible to buy and install it once so i dont have to keep changing it around.

Actually I covered that all the way back on PAGE 2 of this thread.

Thank you Impious, I'm still thinking of a creative way to fit a sundown amp in there. If I do go with the anarchys, they are 8ohm correct? If the amp only shows 4ohm rms Watts, what is the expected power when running 8ohm speakers?

By doubling the impedance you cut the expected power in half.

Actually I covered that all the way back on PAGE 2 of this thread.

lol, dont think the link to page 2 was needed, but thanks.

I'm just saying, before the OP starts adding more midbass drivers, I think revisiting the install could easily fix the problem completely.

Hes got the power & the gear to have decent mid bass, there is no reason to need more drivers.

I read through every page (quickly I might add) and I saw a ton of great information but nothing stressing the importance of install.

Who is to say that if the OP added more midbass drivers with similar install (no offense man) the issue would not still remain?

I know its hard to really be sure of the advice given here on how to help someone when you cant be there to hear the system os see it for your self. Kinda like if someone asked me medical advice on here with out actually seeing the patient... I have Fosgate Power T1652-S's in all 4 corners of a crew cab pick up. I have them in the stock locations. I have not deadened anywhere yet. I dont have the mid bass im looking for, so i had to turn the crossover on my subs to 250Hz in order to fill that void. Thats pretty much the readers digest version - Impious and many others here have explained the techniques of todays stereo to an old schooler like me lol. I appreciate any and all viewpoints. I havent boughten any midbass drivers as of yet, because everybody is trying to make sure ive gotten these components set up right. Audiophyle, if you have any ideas please lemme know, im open to any suggestions because im sure i dont have these high dollar components set up to thier fullest potential...

So... have you tried how it sounds without the groun loop isolators?

What model full size pickup? (so I know what the doors look like)

Generally what is needed is a very solid mounting panel, the more rigid the better. Thats why I said to google "Infinite Baffle", what is vital in that setup is also vital here. (rear sound wave isolation + very rigid baffle)

Depending on space (go thinner if ya have to), I'd cut out a 3/4" mdf piece as large as you can bolt to the door frame where the speaker goes, then cut a hole in it for the speaker. That alone can make a huge difference in mid bass.

If the speakers mount to the plastic door panel, you need to solidify the door panel to make it as rigid as possible. Doing the same thing with a piece of wood epoxied or fiberglassed to the backside of the door panel can do wonders too, then of course mount the woofer to the wood.

Your gear should have zero issues playing well into the 60~80hz range, which would allow you to dial down the sub LPF to a much more reasonable zone (60~80hz, instead of 250hz).

Do what I mention here, and I would guarantee you will notice a huge increase in sound quality. It wont just add the mid bass you are missing, but it will also richen up the entire sound spectrum of the speakers.

Sound deadener is great & has its place, and should be used AFTER reinforcing the speakers mounting locations.

Copy, ill try the speaker mounting reinforcement.

And pull the isolators.... I haven't because there is a buzzing noise without them. A buddy said to run the rca with some insulation through the dash to keep the power away from them...

BTW I did replace the infinity 4 channel with a fosgate power 4 channel....no real noticeable difference at all.

That's a complete myth, no more listening to that buddy.

Gotta agree with Duran.

There is a huge thread on here about engine whine, it will give you all the answers on how to eliminate it without needing the isolators.

Cant say I've ever heard a ground loop isolator cut midbass out, but then again I rarely use/need them.
