Hey I recently purchased a Alpine type x 12" sub. I am building a slot ported box tuned to 32-35 hz. My question is, should I fire it forward, upwards or towards the truck? The "audio" guy I work with says forward. I'm just wondering what is the best experience ppl here have had in a 4 door gtp? Also anyone build any nice amp racks? I got 2 giant amps tht need to be tucked away nicely. PG RSD 1200.1 running the sub, PG RSD 500/4 running my mids. Both amps are 18" long.

Any help/advice is greatly appreciated.
