So i just got my new system all set up in my ranger and am pretty stoked about it. I have 1 sundown sa-10 with sundown's 1000D amp. Also have a pair of hertz energy components amped up with some shitty bazooka 2 channel i had on my old sub. Just metered it at 142.2 with some test tones at 40 hz with a ported box tuned at 32.5. couldnt believe its only on a little more then half gain. Sounds amazing so if anyone is planning on putting a similiar system in a single cab these are the kinds of numbers you can expect.
