I'm not satisfied with the performance of my system at low volumes. If just sounds hollow. At high volumes, it sounds pretty good, but not at conversational level volumes.
Here is what I have:
Clarion DXZ835MP
Profile 4x75 amp
Blaupunkt ODC66 front components
Infinity 625i rear coax
Infinity basslink in stock sub location.

I previously had the blaupunkt speakers and amp, along with some jbl 6x9s in a saab, and the combo sounded great.

Currently, my rear speakers and sub sound great also, but its the fronts (most important ones, obviously) that seem lacking. I dont know if its due to the stock mounting location being not aligned with the grills in the door panels, or just not a good speaker for the car. They are rated at 80w rms and 240w peak, 90db sensitivity.

What I was considering, since the headunit is a high power unit, and the rears don't need that much power anyway, is running the rear speakers off the headunit and bridging my amp into a 2x150, and also possibly replacing the front speakers.

I don't know a lot about speakers, but from the spec sheet, the blaupunkts also say:
freq resp: 60-23k
4 ohm
crossover 3/6khz, i think I have them on 3
10 oz magnet
.014 air volume displacement
resonance freq of 63
elec q factor 1.00 Qes
mech q factor 4.22 Qms
total q factor .80 Qts
volumetric equivalent compliance .35 cuft.
linear excursion, 1 way .12"
dc resistance 3.5 ohms

question 1: does that sound like a good plan for low volume, ie, increasing the power to the fronts.

question 2: if I replace the fronts, what should I get?

thanks

I personally have zero experience with blaupunkts. Regardless, I would say replace those if you dont like they way the sound now... then go from there, because everything else sounds good to me. Those components leave the only gap I can think of.

My fronts suck too, cant hear crap from the kickers up front.

Thought about Focals, but screw the French, going with Boston Pro's.

Bridge the amp and run it to the fronts only. The deck can run the rear (they don't give you that much sound anyway. Placement is losing you some of your sound, but it shouldn't be that bad. I would also turn up the gain to the amp and then try to balance the levels of all speakers. If that doesn't work... then think about replacing. The equipment isn't high grade by any means, but should produce better than the stock system.

yes I agree...or go A/d/s(american)

I've never heard Blaupunkt speakers. But that amp is crap, and anytime you bridge an amp it produces 2x the power at the price of 4x the THD. Running the rear infiniti's from the HU is a good idea and fade the sound about 80% to the front. Pick up a good value 2 channel us acoustics (made in usa) or jbl amp for the front components at about 100-150 rms x 2 and go from there.

You have a good plan about bridging the amp nad should definitely start at that point. Personally, I still like more rear fill though. Once you get that much wattage running to a decent set of front speakers, you are going to drown out the rear fill if running of the head unit. Some people like this so it definitely is not a bad thing. Do what sounds good to you and tweak accordingly.

well, 1st I'm gonna adjust the gain, turn it up a bit. The way I had it set, I turned it all the way down, then turned the HU to max and adjusted the gain til I got distortion. Perhaps it would be better to adjust it higher. As for the quality of my equipment, it sounded fantastic in my Saab.
Next choice will probably be some Polk Momo speakers, then lastly a new amp.

lol I just saw that I qouted myself...

I have my pheonix gold amp bridged running 150watts rms to my speakers and it made all the difference over just 75watts.

That was party due to the fact that A/d/s chew up power and the amp was able to control the excursion levels I was asking from the speakers...

moral of my post, bridge that amp!!!
