Hello people,I’m new on here and been out of installing and building car audio for some time now. I finally picked up a truck I’ve been after for some time now and ready to build a nice loud and low playing truck. I have a 2002 Chevy S10 Xtreme extended cab and trying to do two 15” FI SP4’s on two SQ 3500’s. The equipment I have had for many years now that’s why it’s older stuff but it’s all brand new. I have a h.o.alternator,runs of 0gauage ofc,and limitless lithium batteries already. I also have a CT Sounds four channel amp ready for the mods and highs. What I need help on is my box design because I’ve never built anything for this truck before so I don’t know what will play super loud and low. Then on what mids and highs will play really well in this truck also. I am ready but am clueless on where to start thanks for reading this and hope to get some help.
