Pls also advice me on the foll gurus,
1.Dual functionality- how to use.
2.Surround sound -should be it on?

Someone adviced that use of centre speaker(alpine small unit) reduces the bass and surround function usage ...........

Totally confused.

The best way is by ear. First set up your front speakers, then set up the sub so it feels like it is integrated to the front speakers. then set up the center and lastly the rear.

1. NO twin coil subs are just as good and at times a LOT better than their single channel counterparts.

2. NO using the center channel will NOT affect your bass level or quality. it is basically adding a surround sound 'FIELD' to your car. this is to give movies a realistic experience. but in cars it also makes things in music clearer and better 'staged'. It has not much to do with bass. In your setup that is primarily your subs job.

Speaker distance is a kind of time alignment. If the HU has the feature, it should be available when a CD is playing. It does so in the AVX800.

One more query on the frequency adjustment dial in the JBL GT5 A604 and JBL GTO3501. Probably Sam can help. Pardon me if I sound silly.

The rotary dial in the 604 shows a min of 32Hz and max of 320Hz with no frequency value markings in between. Can we assume it is a linear scale? Which means can we assume the frequency value at the center is around 175Hz. I think it is not a linear scale but there is no way to find out. Can gurus comment?

Sam would be the best to comment. but IMO it is linear and is in 10hz increments. so you can assume it to be that much but let your ears be your guide.

I don't believe any question is silly it could have been anybody's doubt.

@Pradeep speaker distance adjustment is universal to the system and only needs to be done once.

I saw pictures of lot of other amps where more markings are there, but it is not linear. For eg mid point is around 60 Hz in a 32 -320Hz range. Hence the confusion.

the scale is not linear because it is logarithmic

Could i butt in with my query? My amp's set at hpf:80hz lpf:80hz
HU set at hpf:63hz lpf:63hz(i.e sub)
Will this result in missing frequencies?

I guess you will lose the 63Hz to 80Hz range. You can lower the HPF at the amp to 63Hz which should take care of this.
