Questions... Questions...

i have a few ICE questions...

1. What is the meaning of SPL? I saw this on the magnet of a pair of 6' BMBoschMann Speakers...

2. My car interior light gets dim everytime i hear bassy tunes... when 'buum' sounds... the light got dim... even though it is not very loud... what is the problem and how to correct it?

3. Still about the light... if i install a 4+1 power-amp plus a sub, will this worsen the light condition?

4. I heard tht if a person is upgrading his ICE, then he should change a performance spark plug and cable... is this true?

thanks in advance...

SPL - Sound Pressure Level; which is not of concern unless you're setting up to take part in a 'DB Drag' competition; SPL on a 6" speaker in total marketing bullshit.

Light dimming during 'bass-heading' is either your battery, alternator or your supply grounding problem. Your installer could be cutting corners by using a single '8G' to supply more than 1 amp.

I LOVE THAT 4TH QUESTION.................DUNNO WHERE YOU HEARD THAT FROM.

Yes, check your power system-charging, battery, grounding etc.
The answer to your question 4 makes no sense at all.
In fact I heard of performance spark cables will induce noise into the system.

hehehe... made a fool of myself with the 4th question... but thanks for the info there...

so if i change the alternator from 75A a bigger one... say 125 A.. will that solve the problem? coz the batt is ok so as the grounding... have tht checked jus a month ago...

Quickshift... what do you mean by "Your installer could be cutting corners by using a single '8G' to supply more than 1 amp." can explain more???

 

[pisces23]

For a normal SQ system, 75A altenator should be OK.
I think what Quickshift meant is your installer might be using a 8 gauge power cable from the battery and then split again near the amps to power both.
By right you should be using 4 gauge power cable all the way to the amps, or at least from a single 4G wire split into 2 8G wire for the amps.

i think you all got my 3rd question wrongly... what i mean is does instaling a new amp helps to solve the light dimming problem?? or it will worsen it? i havent got the amp installed but it is with me... dun dare to install it bcoz scare might spoilt if insufficient power supply to it...

sorry for the unclear question...

Always remember that more amps doesn't mean better sound if the setup is not done properly. Blinking lights and amps are separate cases here. Spare a thought first for your charging system and 'grounds' if it's an older car you're trying to 'ICE'. My opinion here is for listening pleasure so-so SQ, R&B, Canto-Pop & mild-techno; 1 good quality 4 pre-out head unit, 1 5-channel class A/B amp 50W to 60W X 4 & 80W to 100W X 1, 6.5" bass-mid rated 100W & tweeters up front and 1 pair of 2-way 5" or 6" at the rear will give you endless listening pleasure. Forgot about 12" single enclosure and the 4G power supply cable.

another questions here... hope you guys can help me... my HU has one RCA output... so can i connect it to two amps? if can... what do i need???

 

[Beetle]

Yes can, you need 2 pairs of Y-RCA connector to separate each signal
I have them for RM10 each if you want. PM me
TQ

Yes you can.
Beetle's suggestion is the cheapest (I think). If you want, you can go with equalizer or electronic crossover.

yo bro.. thanks for answering my question... but why two pairs of the Y-RCA? i think one is enuff liao eh??? btw... how does it look like? can post picture?

 

[Beetle]

bro, why 2 is because you are splitting your left and right mono signal into 2
meaning left RCA ->Y rca
right RCA ->Y rca
Thus in the end you will have to pairs of RCA coming from 1

pic: The yellow cables are the Y-rca

 

[craziechild]

beetle,

thanks man for the pic.. it does explain a lot...

 

[Beetle]

sure,
if u wan the cables let me know
:)

i just borrow this thread for a while since you guys were talking about power cable
i notice from my batters there is a single guage 8 ( i think, what is the diameter of a guage 8 cable?) so maybe my installed could be using it to power 2 amps.

what are the long term effect of this method to power 2 amps?
