Can't give you a "who's better" but I have been happy with Noico. At the price point it really can't be beat. Hushmat is usually considered the "best". Noico best for your money and Dynamat is name brand overpriced.
As for a Amp install kit - To keep things simple I'd go for a KnuKonceptz 4...
Tired but sober, you understood what I was saying. 4 Amplifiers and 4 power/ground wires. Anyone doing that would either bus bar or "distribution block" in the car audio world. Depending on amp power requirements, size the 4 amp wires and then final power wire accordingly.
I assume he's talking about 4 amp power input and grounds? Depending on amp wire sizes he should bus bar right off of the amps to a single wire up to the battery and then make sure the primary wire and ground wires are the same size and matched for length/amperage the amplifiers will draw.
Its the internal camera ground, not something that you can resolve by cleaning any chassis grounds on the car, most likely you'll need a filter capacitor wired into the harness like this one: https://www.amazon.com/dp/B000CEDZBA/?tag=caraudiocom-20
It will require some manual wiring, a bit of...
While technically accurate I think most go with chassis grounding to limit the length of their wire runs. I guess it really depends on the install and where the batteries are located compared to the amplifiers. Depending on that, would determine how to wire everything together.
How much do you want to spend and what RMS are you looking to push? There are so many brands out there now as well as "hobbyist" level brands that are all great, some just have better highs or fuller mids depending on what sounds best to your ears. Alpine Comps still tend to be well regarded in...
You shouldn't be running grounds from Amp to Batt - The batt's should be grounded to chassis and so should the Amps. Making sure that wire gauges are the same.
Not "owned" but "Hosted" would be a better word. The difference between using a link or uploading to the site. Changes the amount of hosting data/storage required for site Admin.
You can find the "Mark of the beast" in anything if you look hard enough. Probably very easy to find in Monster because that's exactly what they're "edgy" marketing is about.
Absolutely nothing, when I die I will just cease to exist, much like what it was before I was born, no consciousness, just nothing. Thats my personal opinion on death, I can't speak for all Agnostics.
