I have been riding around for about 12 years with (10) Group 31 batteries in the back of my Tahoe. Before XS Power it was Odyssey 2150's....so i am used to having a lot of weight. Somehow, i managed to do it all these years on some 295/25/26 tires with no problems But lately i have been feeling the itch to make a few changes. The system works GREAT, always has, but i want to try some of the new stuff that is out. I am EXTREMELY busy at the shop and don't have time for anything major right now, but since i have a nice row of HEAVY ASS batteries in the very back of the Tahoe, i figured this might be a good place to start. In other words EASY. Easy but HOPEFULLY effective. Oh and 78lbs vs 24lbs....i am saving more than 200lbs on the tail-gate of the Hoe. My eventual plans are: 1 more SB1000-31 under the hood to replace THAT D3100. Then i am hearing rumors (from a good if not the BEST source) that there might be 14v group 31 batteries coming out soon. If that is the case, i WILL be running 5 14v G31's and 5 SB1000-31's. Hopefully some new alternators. These Mechman's still work great but they have new stuff out now and i want it haha! Anyway, here are a few pictures. I have a 15 minute long before and after video rendering right now and it is going to take way past bedtime to finish. I will upload in the A.M. Stay tuned for results! Do caps really help? Find out!

Pantera for the mother fucking win !!! Rad choice chief Look great. I dig the color on the new cases even more that the old 3100s. You add a few more banks, and bring your charge up a bit, that will hold rock solid. Good shit man. Grwt comparison vid. Love the end side by side comparison. Well done yo.

i just want to apologize in advance for the shitty mic sound at times in this video. I have a new Osmo Mobile handheld gimble and i think it is muffling the microphone or something. This has never happened before...so bear with it, as annoying as it can be. I am annoyed by it too! LOL. But voltage drop comparison is more important in this video than the actual sound coming through the camera mic. And one last thing for those that don't know. The system SOUNDS GREAT in person. It is as clean as it is loud. The subwoofers cause the camera mic to distort (not related to the muffled sound during commentary). But know that it don't sound distorted AT ALL on our end. Thanks! grab a sammich and Enjoy!

<3 me some caps How are they treating you?

oh also, before you say anything about my ragedy upholstery in the back, it obviously USED to be a lot nicer....but i have been beating the SHIT out of everything you see there for years and it takes its toll. Just the hatch rubbing on the trim pieces over the years and the bass slap hitting it is enough to wear it out some. But the good news is, the system STILL works great after more than a decade. Just sayin'!

For the NeoPro 6.5s freq response is about 60hz to 4,000-5,000hz, they really drop off after 6,000 hz which anyways most tweeters are already playing in that frequancy. So if you have a tweeter such as a "Pro Audio" style super tweeter like say Seleniums that dont like to play to low in the midrange the neopro line will match up great with them. The 60hz frequency is tested in an open freeair style application (as if it was in your door), If you build sealed fiberglass pods for the neopro drivers they will play a little lower and be safe doing it (but you must also take in the power your throwing at them). This line of speakers where made to be like a OEM door speaker where it is played in a open door that is not sealed, they will play much lower then your other types of "Pro Audio" speakers (again selenium, they lack midbass something fierce), not the case with the neopros when they are even used in a freeair application. The 8inch neopros are asked to be crossed over at 70hz, both the 6.5s and 8s have a 2inch voice coil, same suspension and power handling, while the 10inch neopros use a 2.5inch voice coil and a slightly higher rms rating due to the larger coil. Personally I would run the neopro speakers and whatever tweeters you chose to be ran active like others have said. So that means a 4channel amp would run 1 neopro per channel on 1 and 2, and 1 tweeter per channel on 3 and 4. Of coarse you could wire 2 speakers or tweeters per channel if you wanted to lower the impedance a little bit. Here are some Neopro 8s and a pair of slenium st-400 tweeter I played around with powered by a sundown 100.4D ran active. IIRC I had channels 1 & 2 bridge to the mids at 4ohms (2ohms per channel), and the same for 3 & 4 powering the tweeters to get more power out of the amp instead of wiring the amp at 8ohms per channel since all speakers and tweeters are 8ohms. So the amp was doing ruffly 320watts per set of bridged channels, or 160watts rms per speaker. So you know the neopros are strong! http://www.youtube.com/watch?v=vCwiuBZlLBU Here is the response graphs from sundown for the neopros
