    so have my meter set to ohms and do a since wave of same hz? watch meter while doing this and what volume should i try this at at? and can i do it at the amp or just to the input speaker leads from subs. So just wire it back to normal for music when not doing spl tests.. wish my amp was stable for playing music wired at .5 so i could get more power to them instead of 400rms each ugh need bigger better equipment

    the mic was on dash when it did 142db and then 136db with it on dash sealed, when the clamp was done it was done using a burp at 36hz and thats what my system gets its loudest with, the guy has a tool thats used for everyone to place meter on window and ive got a meter thats been calibrated with termlab that dave proulx sells and ive tested before show and was showing same db but wanted to make sure and it was right on with termlab. I have done a ohm test with subs and it shows 2.2ohms. If i take my voltage up to around 14.9v would this maybe help and work on two new batterys and bigger amp alternator. how do i find what subs are rising too? because at rest with subs not being played for hours there at 2.2ohms wired together

    so i went to spl show and wanted to see what my two sq hds200 dual 2ohm that is wired for a 2ohm load and even checked them with d.m.m and shows 2.1ohms but my mtx thunder 1501d older style no elite suppose to do 1500wrms@2ohms with 14.4volts has 2gauge welding wire and at the car audio show it only clamped 844watts. Im wondering why is this and is there something im  missing here and how to fix this to get my wattage up because my spl score in my 00 s10 ext cab was only 142.3 on dash http://www.termpro.com/asp/officialevent.asp?EventID=15579&Method=1000 name is david downs i entered the hardcore truck so i could have door open driver side and then unlimited car truck 0-2500w sealed dash was 136.4db. Help me please. I have only one battery and a ad244 alternator 145amp with all manual windows/locks blah blah

    so for my 2000 s10 extended cab i did tone generator today i sweeped and did one at a time on spl meter and found that 36hz is my highest spl reading and its 142.3db driver door open and other windows closed. does that even come close to what my best resonant freq is?

    Well I just got two 10" hds200 and using a mtx thunder1501d and I've tuned and yeh its got louder now but I'm guessing it may be high 130s touching 140db but I'd like to change to set of 12s and want them to hit hard hard and go little lower then the f/s 37 on hds200. I'd even change amp to a sq3500 or like so I could at least double my power ,just want more air and hit most notes I listen to..hip-hop and decafe stuff. I doubt I'll keep the mats since power wise isn't enough

    so odd question could i get two more 10s hds200 and make me a box with dual chamber between the two sets of 10s so four hds200 10''s and have my mtx 1501d on one set and then the mmats 2300 on anouther? Or would this cause issues? i wish i had money for the setup i want but if this would work that be awesome too

    Weird today i was at work then came out and played korn: way to far and I tell you it hits well for 2-10s ive had these about two weeks and seem like there doing better, now i did notice huge difference in quality when friend hooked his iphone 6+ to my input that the volume could be turned up on my radio way higher and no distortion noise.. My cellphone is junk or something so what kind of device should i look into buying? Since i use the 3.5mm input most of time

    So i found a nice nice shape for age mmats mpa-2300 and dont know much about it besides it works, does anyone know anything about these and if they can do 2ohms stable bridged? Im not sure if ill keep it or not what would it be good on since i think its maybe 1100rms.. Lol if I could use mtx and mmats on two 15"s be nice without negative effects

    do you think using dd-1 meter is best bang for buck device? I see the oscope nano handhelds but idk.I had one and went bad so new one will be here monday, Im also considering a second battery if so what size should i go with considering little power that i have. I did buy brand new basshead or down4sound rca cables that i think will be nice considering rca grounds tighten down so no coming off. I have just 2gauge welding wire now and my ground on amp is not off frame just off body inside. should i do frame or body so for sure that its good strong ground. thanks guys ill take dd-1 and try to set everything i use usb,aux and of course cd with dd-1

    hey folks i appreciate everyone lookin and askin questions maybe get this figured out. now does anyone use ipod or cellphone with music files to the aux input and if so is there a good way to check distortion there if its dirty input.. if using the usb songs dont sound as good and seems like bass is weaker with usb
