yeh thanks, i know a 4gauge will work and an 8gauge will work ....but will 10gauge?

8 gauge will be fine, dont really need 4 gauge unless you're planning on improving it alot, 8 gauge is good up to like 1000 watts max. Got a cbr10 vibe active sub and thats powered absolutely fine. Tbh the 10 would work fine but it would limit you quite badly!

i'd upgrade the cable tbh. 10 seems abit small to me.

agreed, i wouldnt use anything less than 8 tbh, theres no need for 4 either 8 will be fine

Thanks everyone, yeh i thought it wasnt correct advertising it for 1200w!!

anyway i bought a 8gauge one, was tempted to buy the 4gauge but it was double price... just need some sun to fit it.
