I thought you already tried a new power supply outside of the car? If you take this amp and power it on your test bench, jump the remote to 12v and just plug in your speakers, still got hissing?

That amp sounds damaged/defective.

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

I used to have an older 12 with the black dust cap, not a bad sounding woofer, alpines type X actually reminded me of the way it sounded, maybe you could find someone with one of those? If your hunting for affordable sq woofers, take a listen to an idmax also.

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.
