Noticed that there have different price range in RCA cable...
Is it can influence signal quality? If yes, around how % ???

well, it depends on ur ear mainly, if u can hear the difference, then RCA influences a lot in ur system, if u don't, it wun matter whichever RCA u use.

there's a rule of 10% of your system cost goes to cable. so 2k means 200 goes to cable. however, if you think about it, this rule does not apply to car audio since cables needed are much longer for car audio, sometimes double or triple the length. therefore, the rule should be 20-30%, which is fair because cables carry signal too and they are a very essential part of any system.

Thanks for kind of respose..
Actually my concern is one RCA that use to support the signal for front speaker as it is main point for me in my ICE setup ? any brand u can recomend...how bout Monster., stinger, belden??? Any idea for this RCA such as quality and prices?

quality = u get what u pay for la, so squeeze to get as high a budget as u can for the rca and speaker cables. yes spend more on the fronts.

stinger, monster, streetwire, audison, lightning, are all reasonably priced for beginners on a budget

Heard that stinger and monster is famous in this area....is it???
Anyway, which this better? if compare same price range one....

not much difference actually if around same price, both also same level

i wont say famous, maybe well known and widely used in mid end systems
