Attena problem stillnot going away. What I found after further research that it has become highly directional. My old KEH santro is much better in that aspect.

It is one of the roof mounted ones like swift. Should I try a chinese make inside the car one. Are they effective. What I remember from my basic oldf days is antena should be atleast 6 -9 inch for FM
I cut eight holes for my home speaker project with hacksaw blades. My palms were red as tomatoes after all the cutting and filing.

Oops ! is the post too late or i got my car early ?

Sony Used Amp to drive SUB

Guys getting Sony XM-2025 I think 20 W per channel Bridgeable Amp for Rs. 1100 ( USED)

This will fit easily fit behind my glovebox. Or Should it be near the sub to avaoid power loss. In that case inside the side panel as sugessted by gunbir.


Dimension are 6"X5"X2".


Now I have to find only a Cheap sub to go with it and build my own box.


Any Sugesstions.

If I remember correctly, thats from somewhere like 1997(ish). Can you confirm its specs and output in bridged mode...

If Im right, its a bit small for running a sub...

the 2025 is too small for running a sub. it cant delvier the amps. it was desinged for triamped systems to run mids and tweeters.

It might give 60-80Watts in briged mode....one can run a high efficiency sub with it (not more than 10"). The combination will work the best if installed in IB.

I think it was 40W rms in bidge and you could run a sensitive 8" on it.

How much is sensitive enough 91 DB/w/m OR 93 /w/m or much higher.

The thing about putting your system is much better than getting it fixed, But I have very less patience. I try to sneak every night to work on the car. I do not know how vivek manages it.( to wait so long)

By the way the front are almost comissioned . First sounds this sunday hopefully

In case of 8" sub...91dB is pretty decent. Though more sensitivity will get you more loudness for same power.

Power sensitivity

Guys tell me If I am right.

If my fronts comp and rear Coaxials are running on 22 w rms per channel and assuming that the speakers are 91db/w/m

would a 40 watt rms amp in bridged suffice with 89 db speaker or I need
more sensitive sub e.g. 91 db/w/m .

I jsut need the fill of the sub so that overall ambienence and car noise or highway is filled out. I really miss U2 and lion king without the sub.



How about this
http://www.mmxpress.com/Pioneer/tsw304.htm.
Retaling on streets about 1500.

off course using a sealed or ported box. Just started the reserch today. Plan to build my own

Bridgeing the amp

Often I hear the term bridged amp and 2 channel bridged.



Does it mean the two output channel outputs are connected in parallel or in series.

Also I have seen woofers with dual coils. Does that mean each voice coil gets seprate amp input or are they paralelled or are they in series.??





If I am am not wrong each combination will acahive a diffrent power delivery

Infractions: 0/1 (10)

Bridged Power:
When you bridge an amplifier, you combine the power output of two channels into one channel. Bridging allows you to drive one speaker with more power than the amp could produce for two speakers. Because of this high power output, bridging is an ideal way to drive a single subwoofer..
Usually, an amp is bridged by connecting the speaker leads to the positive (+) terminal from one channel and the negative (-) terminal from the other channel..


Voice Coil:
The voice coil consists of a former (or bobbin) with wire wound around it. The voice coil is attached to the bottom of the cone and extends into the air gap surrounding the pole piece. The voice coil translates the magnet's energy into cone motion.

Dual voice coil subwoofer:
While typical speaker drivers have one voice coil, dual voice coil (DVC) subwoofers allow you the advantage of flexibility in wiring your system. Parallel wiring provides for maximum amplifier output, while series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. In series/parallel mode, you can wire 4 woofers to a single amp, for example, and still maintain a compatible impedance. Independent wiring lets you drive a single sub without bridging (or by bridging a four channel amp to one sub)...

hope that helps ur query..

Pranil... dude... Lion King?? arent you a little old for Hakuna Matata.. hehe

No man... stay away from the pioneer subs... they suck big time...

Ok, again, heres what you can do, get a nice sensetive 8" or 10" and do an infinite baffle install in your spare wheel cavity. A sealed box requires more power and since you are on a watt budget, its better to do an IB.

You could use the Hertz Energy ES200 - 91dB. It will work well in your car. go to http://www.hertzaudiovideo.com and look in the tech section for the install manual. Besides complete specs, it has other useful information like parallel / series impedance configuration etc.

mclaren, thanks for those definitions. Sam see i found my understudy! Between Vivek and McLaren this thread is in safe hands for the next 20 years.

Pranil there are nicer subs than the Pio 12" unless ofcourse you have a budget.
