High time to change speakers?

[Vivek]

you can provide 50w rms to 40w rms speaker, but make sure you set the HPF on the HU.
Higher frequencies contain lesser power compared to lower frequencies. Hence the same rule doesn't apply to subwoofers. orelse, it will be a smoke test demo.

funny aha! .

Hey vivek, your pic. shows socket (female) type adapter, not pin. I assume that auxin in my HU (as shown in my earlier pdf attachment) are socket type only, not pin type. pl recheck.

which amplifier would be best mat to THX401 Blaupunkt then?

EDIt:- Is there sound quality difference while listening HU from external unit i.e.i-pod or mobile? anybody experienced sound difference of songs playing by HU and same song playing by external mobile/i-pod?

[Vivek]

@ pkhd, yes, my mistake. you need to find the counterpart connectors. They are available.
When I connect my iPod to my pioneer it plays well. But its USB. In Aux-in, make sure you turn off the EQ settings on the device and adjust the EQ on HU. Theoretically there would be some loss in quality, as it is two-turn conversion. I have seen the difference in the home audio. It is same here also.

[pkhd]

In Aux-in, make sure you turn off the EQ settings on the device and adjust the EQ on HU.

finally i succeed. I can set EQ settings from both device ie mobile as well HU also. Expert here pls comment on this. Also I found sound low in Aux-in mode compare to USB and CD option. Why happens this? Is it normal?

Hey, I also observed one separate sub woofer RCA o/p given in HU. Can I plug any good sub woofer spkr directly to this RCA without Amplifier? Is this deliver real sound as in conventional setup - sub woofer with amplifier.?

[Raghu]

Usually the sound from Aux-in source will be weak compared to USB & CD, as the level on aux-in depends on the source. and in many cases there will be little loss of quality, most often in high frequencies.

RCA means line level signal or pre-amp signal and is very very lower than the speaker level signals, but it will have negligible distortion or noise. So, you can use the RCA connector only with an amp. Seperate subwoofer RCA is very good, meaning, you can seperately control the subwoofer signal levels and low-pass-filter for sub.

thanks raghu for clarification.

which sub woofer should i connect to this separate subw RCA (5 & 6 channels as shown in attachment) to get real sound. I happy to know that i can add subwoofer without amplifier. Yeap in my clarion hu, subw volume control and LPF control are available separately. (Attaching wiring diagram again for ready use)

As u know my setup is 6x9 rear and front 4" coaxial, does adding this subwoofer make sense in view of SQ & SPL. Any change required to it?

[Raghu]

No no.. you got me wrong. I said you can use RCA only with an amp.

[vicjain]

any amp will do with it ... all u need to take care of is gain control setting in amp. dont use the bass booster and set it at hpf at anywhere above 80hz where u find there is  no distortion.

[pkhd]

Hmm...

To check again, i am talking about 5 & 6 channels (look into diagram pl) where clearly mentioned by them(Clarion) that...
"Attach only a dedicated subwoofer speaker to the subwoofer connector. Connecting an ordinary full-range speaker may cause high-frequency noise."

[Raghu]

Oh.. but usually RCA lines are pre-outs. Just check, how much RMS power these 5 & 6 lines can pump to subwoofer. And please check whether your HU support "Direct Sub Drive" feature. If yes, then it can pump power to drive your sub. In pioneer it can pump 70W max. power on direct sub drive lines.

[vicjain]

well in any 3 preout(set) HU , thr are dedicated front + rear+ subwoofer. so in any those system u will have lpf and well as direct sub drive( controlling subs). so mid range speaker connection is not possible in sub preout. they are meant only to control low freq spkrs. but u have to amplify it otherwise it does not work.

[pkhd]

max power 53w x 4 ch as well average power o/p 22w x 4 ch. What say?

pl refer specs attached

Yes. this is normally the case in many HU. The continuous o/p is what really matters, and its in the range of 17 (older HU)- 22W(recently). But anyways, 22W is not really sufficient to power 55-60 W speakers at higher volume levels. Amp. is the solution for that.

[pkhd]

fine. now its clear that amp must be there with subw. ok.

-adding subw to current setup (front 4incher cox + 6x9 rear) would make improvement in SQ level?

-can i fix this as center speaker (between two front sheet, around handbrake space) rather than putting it in luggage room? or any potential position if have in your mind in view of sound balance and quality? (Target is to save luggage space in boot)
