I have a 1984 s10 ex cab. I currently have ran single sub set ups in the past and currently am at the moment. I'm running a single 18, off a dd z1a in a box tuned to mid 40's. It sounds decent but im considering running 2 subs. I was just taking opinions on what i should build next. Any input would be nice especially from my guys working with s10's on here. I'm considering running 2 15's but i want other opinions as well. feel free to comment!!! Thanks guys!
