Dual 12" Subwoofers in '07 yaris

[rszabla]

Hello fellow yaris goers! Just showin off our first project on the 07 hatchback. We slapped two 12" subs in the back in our custom built ported enclosure along with a shiny new head unit. Will post more pics soon

Nice,

That amp looks so tiny for the 12's

Wooh. That is way, way too much thump for our tiny cars. But if it suits you, rock on.

guess you either have your groceries delivered or you have another car to get them? lol

[Spidermandud]

^ His groceries hover above the sound-wave haha.

Good stuff OP!

I've got 3x 12's running off of 1200w in my Echo, and if I was any dumber, I'd go bigger.
By dumber I mean worsen the hearing loss I already have lol

I'm sure I could massage a pair of 18's in the back if I really really wanted to.

[why?]

that's insane. 1 150 watt 10 gave me a constant headache. Had a friend run 4 10's, could here him 1/4 mile away. I think i would die.

[sqcomp]

Wanna borrow a real amp or two to power those subs?



I can guarantee that you'll have more that 1200 Watts...

[sqcomp]

You know what...yes you can get more than 1200 Watts out of either of those amplifiers.

I was also being jovial and messing around. Unless I'm missing something in translation with your post, you're trying to bring this down. don't do it. It's not nice.

[sqcomp]

I must know something you don't...because I can make the amps put out more than 1200 Watts and not even have to worry.

Actually, anyone can. There's no magic juice, I promise.

By your thinking and calculation, ANY A/B class amplifier would have to have said diesel generator to make 1200 Watts. Even the OP's small amp.

I'll ask you, what do you think my total current draw is with all three of those amplifiers?

enough to make the factory alternator tear its self off the engine and run away

that doesn't take much with the yaris. when i was running a lightweight battery with the 150 watt amp my alternator desperately wanted to run away.

laws of physics do not work in some cars .. I've seen that before and prefer not to argue with their owners

Btw I am a big fan of nicely built ab amps.. using this bro (Classic) in my car

dude now you're just being a jerk. Lay off it.

[sqcomp]

??"laws of physics do not work in some cars"?? Seriously?

Current draw is a vital link to Ohms law. Of course you don't care... it's because you're mistaken.

-Read the signature-

Question to all, not just our esoteric sage, what happens when the alternator can't put out more than it's rated output? This will lead to the answer...

[sqcomp]

SPL guys use batteries...

Your're getting warm brilliant one.

Now pour through my posts and figure out what kind of batteries I'm using. Now, answer the question. What happens when the alternator can't put out any more current?

Yes, I can put out 1200 Watts.

[mazilla]

...meanwhile, the OP is like "WTF is going on in my thread?"

[sqcomp]

Truth...We got off on a tangent regarding where current comes from.

This could go a lot further into the rabbit hole as well. There are quite a lot of variables into maximum output of amplifiers that we haven't talked about.

Oh, here's the answer:

"As long as the engine is running, all of the power for the accessories is delivered by the alternator. The battery is actually a load on the charging system. The only time that the battery would supply power with the engine running is when the current capacity of the alternator is exceeded or when engine is at a very low idle. "

Tolms still tearing through posts looking for what kind of batteries I use...

I'll save him the trouble:



That's been updated actually. I'm no longer using the secondary battery. The primary sits at a hair over 12.8 Volts and charges from the alty at anywhere from 13.9 to 14.3 Volts depending on the temperature.

Description:

◦SPP1200 includes removable brass battery posts for installation flexibility.
◦12v Dry Cell Valve Regulated Lead Acid Battery (AGM)
◦SPP Series Batteries are good for over 400 full discharge cycles.
◦Internal resistance: <4.0 mOhms = Ability to quickly deliver power. The lower the number the faster the delivery.
◦20 hour rate: 2.20A/44Ah
◦5 hour rate: 7.48A/37.4Ah
◦1/2 hour rate:55A/27.5Ah
◦5 Second Cranking Amps: 1200A
◦CCA: 560A
◦Watts: 2400
◦Peak Discharge: >2600 A

im learning as well.... so u don't really need to replace the stock alternator to hook up more let say 1000W rms total ? as long as you use that stinger battery ?

by the way that L1 Pro SE is sexay !!!
