Thanks,gurujis!
About my other query?

the installer would be quite technical there. but how did he mange to bridged the HU.. I wanna know how. also the component sounding hollow is due to the door acoustics playing try damping the door..it will help in changing the sound a bit.

I'll give you a 100 opinions nitrous, but they're not allowed on a family forum like this one.

Go and UNDO this, before the HU goes up in smoke. That's why it's sounding hollow.

Nothing moronic about your question. The simplest way to increase the bass from your components is to lower the frequency of the HPF. Going to 75-80 is OK.

If you still need more bass even 60-65Hz is ok in your volumes levels are not too loud or your XO is steep (4th order).

Right you are, Sam.

Imagine the top half of the sinusoid being mixed with the time shifted (that's what the rear channel is) bottom half of the rear channel sinusoid mixed into the same speaker, it is a wonder that it sounds music at all (OK, the front to rear internal delay is small but still). It would really be sounding like the ghostly echoing sound of dream sequences and Ramsay brothers' horror movies.

I am running my speakers with the HPF at 50Hz. I have Infinity 5010cs in the front and Alpine S-type 6x9's in the rear. The components are running off a Magnat 2-ch amp and the Alpine's off the headunit. Will running my speakers at 50Hz damage them? My listening volume is anywhere between 30 to 45 on the Pioneer HU.

It won't damage them. But the speakers do not reproduce 50Hz faithfully, they are not designed to. By raising the HPF to 60 or 70, you will be able to raise the volume even higher and reduce distortion. I doubt you will hear much difference in the low end reproduction in the front.

Numbers are relative. Especially since you're using an external amplifier. 30 to 45 means nothing. It will change with the gain of your amplifier.

Good, I will try setting the HPF to 60 - 70. But I have probably a dumb question. There is no HPF switch on my amp. It has an LPF ON/OFF switch. What is the difference in setting the HPF on the HU and setting HPF on an amp?

Absolutely correct MF. rl:
Your amp has no HPF.

You can't set something that isn't there. Use the HPF from the HU.

I think we are talking about something called FIE. In my HU case you can do a cutoff at 100,150 or 250 wherein frequencies below that are sent to rear speakers only and rest is sent to the front channel.

then 80 Hz range is good also and one can try to do the 100 hz also...

lol: Sameer,

I meant what about a case when I have an amp that has a HPF and a HU which also has an HPF. What is the difference in setting the HPF in such a case?

Sameer, now comes the real dumb question :p. How can I set 60 in this HU LOL!

hi MF,

i mean no offence but why do you think your question is dumb? there is no such thing as dumb q. everyone starts from scrath and it is better to ask then to suffer. please dont say that again :-) :)

the only difference i can think of is maybe the slope and you can adjust hpf on the fly from the HU. IMO it is better to run the amp flat and use the lpf and hpf from the HU.

cheers

as long as you dont hear any odd noises (a la tearing or phut-phut or brrr-up etc..) you are ok. At low levels you can play the speaker fullr range.
