cca is only 2/3s conductive as ofc so yeah the wire can handle 250 amps but will have a good amount of voltage drop as the resistance is much higher you usually need to jump 2 gauge sizes to compensate

it may help it may not it just depends on how many watts your running but i always like to use the biggest wire i can fit, i had a 200 watt rms amp and single sub with 10 gauge, and my current setup 1500 wrms is running 8 gauge power wire

if you want something cheap, i got some royal excelene welding cable, 1/0 gauge it was 68 bucks for 25 feet and its pretty flexible for the low strand count, tsunami makes some decent wire, kicker, rockford, are expensive but are good. and knuconceptz is good and relatively cheap, just stay away from cca or ull have to get a much bigger wire, o and stay away from db link i got 2 db link wiring kits one 2 gauge and one 4 gauge and they are both cca

Did you check the rcas to make sure theyre not bad. You can check the voltage on them w a dmm to make sure they didn't get pinched or just give out

yes you can but set your gains properly

• Vd - Maximum linear volume of displacement of the driver (product of Sd times Xmax), in cubic meters. "This parameter is the Peak Diaphragm Displacement Volume — in other words the volume of air the cone will move. It is calculated by multipying Xmax (Voice Coil Overhang of the driver) by Sd (Surface area of the cone). Vd is noted in cc. The highest Vd figure is desirable for a sub-bass transducer."

Bass boost is good for boosting frequencies that arent loud enough and I know better than to add too much boost. But none of this is relevant to the situation, even with everything maxed and half volume I don't see this amp pushing enough power to fry the coil instantly. I could see it detaching the surround or "spider" or breaking a tinsel lead from over excursion but none of which happened. And I should've reworded my previous post as I didn't know where I needed the boost or notand at what frequency I may have needed it at

no half gain and half volume i didnt set the boost as i didnt know what frequency i needed the boost(it has a variable bass boost frequency)

I think you are getting free air and box mixed up Impedance is lowest as the box tuning point, but if the sub is free air - impedance is highest at it's Fs i may have been wrong on that point as i have not been able to test subs in multiple boxes but it still doesnt change that i got a 2.5 ohm rise when i clamped the first amp and sub

now that is hilarious, even if the amp has dirty power at HALF everything it would not smoke a sub in the time it takes to turn it from 0 to 25, unless i was throwing a cpl of thousand watts at least to the sub, and as you so elegantly put it how could a "shittypipe" amp do that

so your telling me that shitty amp threw enough power at a sub in two seconds at half volume that it fried the coil, i highly doubt that, and if it could throw that much power then it obviously wouldnt be that shitty, thats what i dont get. now what sounds more beliveable that hooking up a not so good amp to a .2 ohm load will fry it instantly

if you read my post right the first time you would see that i did clamp everything when it was on the zues amp but i did not get a chance to clamp it on the new amp dues to the fact that it smoked as soon as i turned it to half volume

it has a slope that falls off slowly now the box will change where the slope is but it doesnt change the fact the the lowest impedience that i saw clamping that amp on a 1 ohm load was 2.5 ohms(which i call a relatively high impedience rise) so i wasnt pulling max power from a 1000 watt amp, and this sub is rated for 1000 watts rms so i was well below the threshold of the sub

really if a sub doesnt give you impedience rise then how do u calculate the fs of a sub, you play it free air and the frequency that has the highest impedience is the resonant frequency of the sub

the coil isnt burnt at all, i dont smell it and the most watts i had on it was around 750(i forget the exact number but those subs have a relatively high impedience rise) and it fried the amp after the two seconds it took to tun the volume to 25 with the gain down

the warranty is through sonic so i figured id ask them, i doubt my amp will be covered but its worth a shot

I ordered a pioneer champion pro 12 (TS-W3002D2) and i had it hooked up to my hifonics zues 5 channel without any problems, i got my sx 18 in and swapped the 18 for the 12 and hooked the 12 to an audipipe apsm 1500 and as soon as i turned it up the amp fried at about half volume, so i checked everything out and final impedience ran in series was .2 ohms so i took the sub out and checked the impedience of each coil and they were reading .3 apiece, the sub is under warranty but i was wondering if the warranty also covered damage done(fried amp) by the sub shorting out.

I like that alot, Nice symmetry to it. thanks, im a big sucker for making everything look clean, i built that for my brother in laws explorer and it took me a week to design it cuz he was so picky lol, i still kinda wish i wouldve added an extra cube to it, thats y we mounted the sub inverted but i think it looks totally badass

it sounds awesome too http://www.facebook.com/video/video.php?v=249280141834208

just do the research and practice and you can get that good, i spent a month on this forum soaking up every bot of information i could and with the help of 4 years of woodshop i created the box in my build, the link is in my sig and i also made this box that was my first box that wasnt sealed lol and it came out awesome

lol that is awesome

its a high pass and a low pass all in one, think of it as a bass amp with a subsonic but it just works at higher frequencies

i got an 04 wrangler

i got some stiff carpet for covering boxes and just lifted the box up enough to slide it under cuz i was in a rush, had to take a trip and didnt feel like dealing with the rattle box lol, but it slid in easily. i dont think the spray foam would be adhesive enough to hold the box but if u could lift the box enough and spray it in it would deffinately stop any rattling

i had my box on bare metal and 35 hz and below it just sounded like shit, the bass was good but i could just hear everything in the rear resonate, even after i put the l brackets in it still did it, so for shits and giggles i threw a piece of carpet under the box and now its nice and clean (o and i had to remove my rear wiper cover cuz it rattled like crazy too) it was just the floor was resonating against the bottom of the box.
