im running 2 12's kicker with a stock deck ..

i havent installed it yet but is this gonna do anything bad to the subs or amp?
will it perform correctly?

yeah im kinda low budget on the deck ... planning to get a alpine
but they dont have the one i want in stock cda 9815

 

It won't do anything bad to the subs. If anything it will make them sound better...you'll probably have to readjust your amp to compensate for the better signal from your new deck. Make sure you hook your RCA's to the sub output on the new Alpine if it has one.....

 

no no no im going to run the subs on a stock deck for now ...

and wondering if it gonna work good

 

it'll perform FINE. it will sound 029348234 times better once you have the 9815 on it and tune it accordingly. stock deck will have no adverse effects on the amp/sub. you'll be fine.
