rca's question

[ghostlyrich]

guys i have a question for yea i currently run these rca's on my speakers which is the 5000 series stinger rca's

and i also run the 4000 series on my sub which are the the same thing just red. they both have the same stats on the cases and online. my question is i get stinger rca's for realllllyyyy cheap and am debating if its worth it... i have done home audio and car audio for a while but am curious to see if you think there will be any difference. stinger says +25 db which no sane person could believe but what i am asking is do you think it will make a difference in any aspect. majorly just trying to save money were i can to direct it in area's that could use it more but at the same time do not want to cut corners. this is the 8000 series i have a chance at upgrading to for cheep
