Need some help here.

Problem is, with money spent, sound right now is very disappointing. I want to do some serious justice to my Pink Floyd, SRV, Rush and other classic rock collections and this so far isn’t cutting it. The amp settings were done by one of the “installers” I have dealt with. It just doesn’t have the “WOW” type sound I am looking for. The bass is too centered in the back area and not enough in the front, especially at the lower volume levels there is almost no bass. The sub-box is ported after trying a sealed box and cals for Vb look right. And the kicker is even the volume is lacking,,,,,, HELP !!!! Thought the Focals were going to have a better low end, or do I have somthing else going on????    please read on if you have any advise to offer.

Description:
-Head unit Panasonic CQVD7003U,
-Focal polyglass165v2 (2 sets) mounted in the front and back doors, with the tweeters flush mounted in the windshield columns and the door columns,
-Focal CX/690 CV1 in the back deck,
All being pushed by a JL 300/4 amp.
-The trunk holds the (2) JL-10” 10w0’s pushed by a
-“Depth Charger” 2 channel (bridged) 400w amp.
   
Why am I not getting the sound????  I do not want the cheesy BOOM BOOM stuff.
Now:
I have a JL-450/4 amp on the way, seriously considering adding the JL-1000/1 ditching the Depth Charger and am thinking of the Alpine PXA-H701 for boosting the signal into the amps as well as the EQ setting capability.

All this is in a 2002 Black Lincoln LSE with ground effects, sitting on 18” Polo Spy’s. Paint is in good condition and when the audio is DONE will have a Pink Floyd graphics paint job done.
   If I get the amps (450/4 is a done deal) and the H701 is this going to make me smile or is there something else I am missing???????

The only solid advice that I can provide is that if you end up with a 1000/1 I hope you are going to upgrade the subs too. I don't think the W0s will last too long on a 100/1.

The tweeters could be too far aways from the woofers to create a good soundstage.

I'd say thing more than likely things just need to be played with a bit until you get it to sound as good as possible to your ears. Seldomly (if ever) can something be hooked up and sound as good as possible right out of the box.

well first off.... great choice with the focals. The tweeters were designed to be on axis so if you dont have them pointed at you they probably arent sounding like they should. Your head unit could be making a big difference as well. I dont know much about your specific model but i do know that panasonic isnt considered a high end deck. I would recommend eclipse with alping coming in second. Eclipse decks come with 8V preouts which help considerably. Also they are well known for their SQ. Your third potential problem could be your subs. the W0 line of JL is the bottom of their barrel. You might want to step it up a notch and get something better. The focals do have better low end but usually only if you have complete comtrol over them. My eclipse deck has a built in 3-way crossover. I am able to get some pretty nice mid range from my focals. You might also want to ditch all the rear speakers and move them all to the front.

IMO your weak link is your head unit.  Panasonic is decent quality and fine for most everyday use, but if you want real SQ you need to upgrade it.  Eclipse, Nakamichi, McIntosh are the first tier commercial choices.

just to add a little bit to what everyone else is saying. Focal reccomends 100hrs of break in time from what the rep said at a meeting a couple of months ago....so just like wine, gets better with age. And yea change those subs out...what i dont understand is why the 300/4 and 450/4? Why not a 300/4 and maybe a 500/1 for 2 10/12w3v3d4? You could put the 450/4s first two channels on the fronts and give them 75watts rms and then use the 300/4 on your rears and they could get 75watts rms instead of sharing 75watts. And then get another amp for your subs....not sure why you got those 2 amps but....thats what i would do if you were stuck with them....good luck!

Hey guys thanks for the replies on this.

Not hearing anything about the Alpine PXA-H701 does any one know anything about this unit? I agree the panasonic is the weak audio link with only 2v going into the amp. There is also the DQS under serious consideration for signal boost and EQ. 

I ended up with the 450 because i got a really good price on it, And with the additional speakers I want to put in the system, I figured it would be a good idea to have "expandbility" for the center speaker (want to change out the speakers on the hump in the front where the original 2 inch speakers are mounted), mid subs in the front kick panels, thinking of dynaudios , but yea they are pricey. I heard a home set of the dyns years ago when I got my 4 Def Tech 3000BP's and the only thing that held me off of them was the price vs size,, lol. Might also pull the 165v2 out of the front and replace them with the 165k2's, then I won't sweat the 150watts rms to the front set.      Any thoughts???????

I sell panasonic and yes you definetly need a new head unit they are pretty poor sound quality. I carry them because dealers like them cheap and 2 year delaer installed warranty. Change that head unit and I guarantee you'll be very happy. My .02.

I would also remove the Panasonic and slide in a Eclipse AVN7000 or AVX5000 like right now. Add a Audio Control 6XS into the mix while you are at it. This provides a great line driver and a easy to use subwoofer level control so that you do not need to go looking through menu's in the cd player to find it.

Hey forbidden, to all that have responded, and to all others that have read over this thread.

I had the AVX5000 installed this morning,,, All I can say at this point is WOW,,, spend the $$$$'s you will not be disapointed. The DCU should show up today sometime but even without this addition there is an entire world of differance in the system. The 450/4 is still in the box, the 10W7's are still in the box as is the 1000/1,, but,,, going to be a busy weekend around here.   WOOOO HOOOOO !!!!!!!

Thank you for the rec on the 5000.

Hi all,

Been awhile, got stuck offshore,,, but lol am back at it again. I just installed the DCU105 that goes with the AVX5000. I picked it up from ebay for 154 bucks. I had to rip the car to shreds, dash was out, seats and carpet, (wife's expression of sheer terror was priceless) to get it installed where the original OEM amp was once mounted in the trunk deck but man it looks like it grew there. Totally out of sight.

If anyone goes out and buys one, check under the hood. I thought for awhile it was dead and that I had got burt for the first time on line but it turned out to be a ribbon cable was not fully set. Having the car torn down was the op I was needing to re-route the cables the local yahoos ran. I am going no where other than MY shop to have stuff installed now.

Thought seriously about a pair of the JL 10w7s for the sub department but had a dealer tell me the 10w6V2 DVC's are a better match for the JL 1000/1 so I think I need to hold off a bit yet, of course if I got two 1000/1's,,, (wife's head would spin around and I would get hit with green stuff) lol

now here is the really cool part.

I went in to the brick and mortor shop to have the guy tweek and check over the system today (O-scoped) and was shown a picture of the Clarion SRK5 center speaker ,, lol SOLD !!! really cool looking lil unit I was just going to blow off the center speaker but this lil thing is going to fit right under the AVX it's a 1/2 DIN with 7 speakersposted_image. I am going to give it a thumb rating when I hear it and will pass it on.

and the answer to the question,, work hard, use your brain, oil bussiness. I am a consultant for underwater (diving and ROV's) projects
