Weigh it, under 50lbs = X, over = zv4. Fwiw, it looks like an X series.

That sucks bro, remember what we talked about? I hoped you would have had a better experience. I'd just rebuild it back to stock with an nsv2 coil and shrink the enclosure until you hit 1.7 net.

The way i seen it, the time on his smartphone doesn't mean shit, defensive body language & how is he going to talk about kindly reaching out to a company when he just recently put rockville on blast? It's easy to accidentally be a hypocrite when trying to cover your ass.

Second video screams bullshit & is hypocritical, will never support them again.

You can attempt a firmware re-flash, if it still dont come back then the internal bluetooth chip probably crapped out. https://www2.jvckenwood.com/cs/ce/mm/firmware/2013/2013b/eng.html

Check your wiring again, inspect your wire for corrosion ect,check every ring and make sure the crimps are locked tight, battery terminals clean & tight & make sure you used a clean thick spot for every ground, sand it down & use zinc washers, bolt it up with grade 8 hardware. If you are 100%positive everything is in perfect order than switch your ground locations, better yet where is everything grounded?

fwiw, on music it's rare to blow two or more at one time,unless you run 5x rated or something so blowing one out of 4 does not mean the signal was clean. If it truly happened on low power its pretty much the amp sending a bad signal or the sub was defective to begin with, assuming you've got electrical and the proper enclosure.

I don't remember the idmax having such a small coil, they seem to get pretty hot off 1500rms & now i know why.. Kind of disappointed with the v4's

Just realised that, woofer fires piss me off lol. A small portion of my back seat just went up in flames because i wasnt able to pull over fast enough to put it out, im sure some of you guys can already guess the brand.

Lol that asphalt based crap... I save it for the floor

If your ssf was all the way up with the sa-8's then that zv3 will KILL the lows compared to the 8's.

Sure. Some amps dont necessarily have an accurate SSF value printed near the dial so just make sure you've got it correct by testing.

Lol yeah thats not helping. Drop the ssf only enough that the woofer dont play too hard under tuning.

that doesn't look bad at all, more port are would be nice but if you aren't getting port noise then eh whatever. Try playing a few songs that are tuned low and keep a good ear on it. If it starts to play lows better as it heats up then you just gotta let the soft parts loosen up. Same thing happens to me when i freshly recone zv3s, i peak above port tuning untill it loosens up lol

Well those 4 8's are very simular in cone area vs a single 15. Also, not sure if your woofer is new but if it is then it will take some time for the soft parts to loosen up. Zv3's & nightshades are fucken stiff from the get go. Takes me about a few weeks to break in my fresh sundown recones and thats off 4500 each lol.
