I am currently restoring a 1973-79 Ford F-100 regular cab. I would like to do a SQ oriented build once it is finished. I know trucks, especially 40 year old regular cab trucks, aren't the most audio freindly enviroment. Has anyone attempted anything like this on this forum? I currently have two set ups, a 2003 Expedition with ID CTX65CS comps, a pair of SA-12D4 on a GS Redline GS10000 with a Pioneer AVH-P3400BH HU and a 2002 Mustang GT with a Massive MKi6 compset, a pair of Incriminator Lethal Injection dual 2 ohm subs, a pair of Soundstream Human Reign Unleashed 4 channel amps (one bridged for subs, the other active for the comps) and an Alpine CDA-117. I will be upgrading the Mustangs front stage to a Rainbow Power set shortly.
