Electric cars and car audio?


Recommended Posts

Driver technology will evolve alongside is what will happen.

 

Currently a Sundown sa12v2 will convert to acoustic energy 2 watt out of the 1000W it's rated for.

 

Ultra light and stiff graphene composites are already starting to be used in audio products:

 

 

 

I guess at some point many years from now subs will become ultra efficient and audio systems will get loud on way less power than they do right now.

I'm not buying an electric car until I'm too old to enjoy myself.... so like....75?

Lol I agree! TeslAs are wickedly fast and have a very comfortable interior but I’ll take a gas car with everything inside flexing from subs as I’m driving over an electric car any day lol

It’ll be interesting for sure! Never heard of graphene I’ll have to check that out

I agree with you, but I think the days of huge SPL systems will be gone. I feel like with electric cars come ultra efficient, decent wattage (not super high wattage) SQ oriented systems. Especially how auto makers are integrating everything through these gody huge head unit screens. 

Also, you have to convert (at least right now) the 400 volt battery system down to 12 volt. That's no safe task. For smaller systems, not a huge deal.

I just want my alternator 🤣

dude built this. He's an electric engineer I think.... even he won't go near the back when he's going full tilt lol. He has a bunch of other videos on the install as well

 

 

that is pretty neat. Have never seen anything like that. Looks kinda complicated tho, I love the traditional look of a bunch of 0 guage and fuse blocks in the back lol

I work on Tesla’s and besides the price they are awesome to drive but the biggest complaint is they list 300-400 miles per charge but because they are so fast and fun to drive you average about 120-180 per charge . These things are fast , I’m not sold on electric cars till I see 1k miles per charge and between 25-35k in price for base model. For me I always pictured electric cars with a motor on each wheel like on the back of the hub so no axles needed  and no wiring all fly by wire , but I think we are pretty far from that a lot of stuff is fly by wire now but no enough still to many wires .

For SPL setups, tap into the high voltage for the amps would be the best way for big power.  100 amp cable goes way further at 250+ volts as well.  This would have other challenges.  Amp designs and other accessories would need to really protect from current exposure, also need to use something like a pyro-fuse instead of the traditional types.  I'm sure teams will figure this out, though it will likely not make it further unless some kind of standard is made for easily tapping into the power vs what you'd have to play with today (like in that Fiat video).

 

For doing high power 12v systems, you could always go heavy on Ah batteries to make up for the small DC-DC convertors in an EV.  You plug the car in anyways, run a quick connect to the 12v by the charge port and do a 12v charger as well.  Most EVs and hybrids have 100 amp DC-DC in place of an alternator, so not going to keep up with a sustained high power.

 

Sound quality is way easier in EVs though.  Once you've sound deadened the vehicle, the noise floor is eerily quiet at speed and many also have the insulated glass.  DSPs are going to be pretty essential with all the factory processing.  Entry level hobbyist doing their entire speaker setup is probably over if that continues into low end EVs, though the sub/amp combo will likely still be simple enough to keep people in the hobby.
