crx hf system help please ASAP

[J_valentin]

Im about to put a system into my CRX HF and i need help on which size subs would be best.

I was thinking 1 12", but i told my friend about my plan and he said 2 8" or 2" 10 would be best, but im not sure which to do. So if anyone has any thoughts on which to get that will be great.

I only want JL Audio subs just so yall know

Thanks for all the help
