Do you only want to run speakers on the amp?

yes

[Bad_Cheetah]

Kenwood M-845

JBL 60.4

Better than boschmann

[Bad_Cheetah]

I saw that too,but it had the Rms of 60*4...should i still go for it?

Bro RMs does matter, but if its a clean sounding amp, and you're running a good efficient pair of components, they would work great together, no worries.

[Bad_Cheetah]

For example

Focal access are 92db sensitive, they are formulated to work great even directly with the HU which would hardly give off 10-15wrms to each channel.

Maddy bhai here is using a Soundstream USA204, thats a 40wrms and he has paired it with components which have a greater rms demand, but still they sound pretty loud.

So what really matters is the quality of the amp, and wesay bhe these chinese amps have fake ratings written all over them.

3000 watts out of a 4 channel amp, that too in 5-10k, thats the biggest lie ever.

Kenwood M-845

JBL 60.4

Better than boschmann

so which one is best among Pioneer 6500f and the two u mentioned above...and kindly give the price idea aswell...

[Bad_Cheetah]

All are equally good, JBL has a slight output advantage over kenwood.

Bad_cheetah, aab baat chak hi gaye hai tu kindly explain sensitivity rating of speakers! Like what figues given in db (decibells) what they show, and how a speaker in terms of sensitivity stands better than others?

Bro sensitivity is basically self explanatory.

To me it is known in the following term.

It is how loud a speaker would go, or how efficiently it would perform given a certain amount of input power.

e.g

A speaker with a sensitivity level of 92db would sound louder on 60wrms than a speaker which is 82db sensitive at 60wrms.

DB, decibles is the unit for the measurment of loudness/sound.

Thus is could say, the more sensitive the speaker, the louder it would be

Not necessarily. A lot of companies use inflated ratings of 2.83V/1W for sensitivity ratings, while infact they should be using 1V/1W for calculating sensitivity. Therefore a speaker rated at 92dB measured at 2.83V/1W will NOT be louder than say a speaker rated at 75dB measured at 1V/1W

[Bad_Cheetah]

Well faking out the ratings is false on the company's part which are making the components and faking the ratings to fool the customers, i hope good companies dont do that.

I just told him what sensitivity means anyway.

@spl bahi
plz shed some light on difference and pros and cones of round port boxes and rectangular port boxes..

what about my question????(A)

[madhouse12]

again splfanatic is best suited to answer it but i'll give u some ideas. round ports require less space so consequently volume of the box (including port) is smaller than comparative L port box. meaning port displacement of round port is less than that of L port. but due to less surface area of a round port, you might face port noise and to overcome this u need precision aero ports that have flared ends. L port gives u long extensions to the bass whereas round port play much accurately.

the above is my understanding of the two. other might give u more help regarding it

thanx for nice info

what is the function of crossover?

[Bad_Cheetah]

what is the function of crossover?

Well a crossovers basic fuction is to direct certain band of frequencies to each driver. So that the sound reproduction is realistic. Your LPF, HPF are also examples of crossovers. These could in an amplifier and also in a HU.

0-80Hz to Mid-Bass
80-300Hz to Mid-Range
300-3000HZ to Tweeter
