What models are you considering? Quality wise Id say they are about the same overall, however, the Lanzar is probably more cost effective. Ive nevr owned an Audiobahn amp, several people I know use them. I have owned a Lanzar Opti1000d and a Lanzar 1200d, never had a problem with either. Both were benched and proven to do rated power.

12's might be too much. I just put two 10's in my ext cab and it's mad crazy loud!!! I drive with my head sticking out the window... I also think that they may be too big for the reg cab. You can always look on ebay for a box. There are a lot of custom box makers out there. Just search for "chevy custom box"

...and at 30 HZ, I guarantee your 10's outperform the 12's. The 12's require far more volume than you will have available, unless you are taking out the seats.

 

If you have a CC, I have designed a super rigid dual 10" enclosure for behind the seat, though it is designed specifically for another, more shallow, driver that outperforms almost all the big names. 130 dB at 55HZ, that's with half the drivers power handling, only 150 RMS.

I built a custom box for my 2002 regular cab. Put "1" 10" driver facing forward, between the seats. If I remember right, I built the box to take up all the space behind the seats up to about 1" below the bump below the back window. Ended up with 1.25 cubic feet. Initially built it ported but immediately redid the box with no port after I heard the result. Had forgotten to take into account "cabin gain", where you'll get a free emphasis of about 6 db per octave below 100 hz. So that's why most people end up with a sealed box. The roll off of the sealed box matches pretty well usually with the cabin gain amplification.

 

I don't think you'll be able to come up with much more than 1.25 cubic feet therefore, and if you're bent on using those 2 12" drivers, you'll be coming up short (I think) on cubic ft per driver. You'll be around .6 cubic feet, and that's even on the low side for most 10" drivers.

 

Infinity Perfect 10.1's are supposedly optimal with .6 cubic feet...could you swing using 2 of *those*?

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.

      Multigate electrical problem

      By rjgvt · Posted

      There was a recall on the tailgate in general for opening on its own. Mine has a cap on it and it won’t let the tailgate open.   My tailgate has two holes in the top of the tailgate. I filled them in with silicone sealant.
