very best?

Put the sub behind the passenger seat, or under it if you can make it fit. Your girl will like it.

I chose to be cheaper and place the muffler under neath the cab right below the passenger seat for this reason.Its not a hemi but it gets the job done.

i had a friend with a silverado, that had 2 kivker l7 8's and they were amazing. and they were only 8's!

I wanted to run the slim vented boxes the comps come in, and run the VXs. But, IDK. I'm just gonna run some shallow subs, that are NOT listed as being shallow. Highly effecient, and quite loud for the money. I'll do a write up when it happens. It will be after I get buckets, because my amp is too big to fit behind the seat with an enclosure. So, it will be in a center console. Along with 2 other semi-matching amps for my speakers in doors, and factory locations. It'll be 1 clean sounding mini...after I pinpoint the rattles and stop them.

I have a box with 3 JL 12w6's in it for my regular cab - damn that thing was loud - I'm too fat now to use it so I run 3 8w6's
Mind you I took a sledge hammer and beat the shit out of that stupid hump in the middle (hehe) !!

The 12W6s are 3" deeper than the 15s Im going to run. LMAO. So, with that being said...you can imagine what 3-15s will be like parallel bridged to my 2100 HCCA.
