So Last week my amplifier blew and i hooked my stock sub back up but after a week of listening to that i decided to try and hook one of my subs to the stock sub harness i just disconnected the LOC and connected up the sub ok now for the question the sub is a kicker solo-baric 10 inch sub it is 450 rms watts with dual 4ohm voice coils which are wired in parralel to run a 2 ohms do you think i will blow anything in the car doing this

 

You're underpowering your sub. I'd say the most likely thing to happen is that if you turn up the volume to the point of clipping the stock amp, you could be sending DC to the sub. This creates the possibility of toasting it. Although in reality I'd say the chance is slim, just be careful. Don't want to have to buy a new sub, too.

 

ok thanks for the advice ill hopefully be getting another amp real soon but i cant live without that extra little bass in my music
