Ive heard those numbers thrown out there alot for amps.

Ok how do you get to those numbers when hooking up an amp.

I know how to hook up an amp positive to posit and negative to neg.

Matched up from amp to speaker. I also know ohm is resistance

measurement. As i understand it speaker connections as far as poistive

and negative are interchangable. left or right,,, either way you connect it

speaker will play.

To read upon this and all other audio/electronic related spend some time on www.bcae1.com. There is a tab on the right labeled "Series, Parallel and Series/Parallel Resistance" which will explain all aspects of speakers.

Basically when you buy, select a speaker it can be single voice coil at typically 2 or 4 ohms. If you buy two speakers @ 2 Ohms, hooking them up parallel will net you 1 Ohm load to your amp. Hooking them up in series, the amp will see a 4 Ohm load.

Note, there are subs that have dual voice drivers in a single package.

 

What he said^. And speaker connections (negative and positive) can be interchangable on cheap speakers that are head unit power, however if you like those speakers and they're running off an amp or even maybe the headunit I'd try to run it the way it's supposed to be and not interchange them. Otherwise you can end up damaging things.

 

The reason for the positive/negative speaker terminals is for proper phasing between right and left channels. The signal going to the speakers is AC, but if the terminals are reverse, the signal going to one of the speakers will be 180 degrees out of phase.

No damage will happen to amp or speaker if the terminals are reversed.

 

Good to know, I had heard it could cause damage a while back, but I'm glad to know it won't.

 

Yeah i went and did a search on it. Got answer to question.

All mine are parallel connected 4 doors,,1 sub dvc memphis. 2 amps

Like daisy chain. So most of the load thing is really for subs???

Ok which one is the one that is more normal for most people???

More for competition sakes,, the ohm load thing.

 

Competition SPL (sound pressure level) typically will use 1 Ohm or even lower. Competition SQL (sound quality level) typically will use 2 or 4 Ohm.

Most door speakers or component sets are 4 Ohm loads.

 

some sterios or amps have a phase control ur sub sonic filter can control this in a way. if i are running ur subs faced into your box. thats when u reverse ur phase which as he stated can be done by tebersing your wiring runnin two subs in the same box out of phase makea them fight each other for airspace. anx ru.ning door speakers out of phase to your left and right channels cuases ur q time to unhinge. ur not gettin the sound deliverd to ur ears at the same time. can make it sound very sloppy

im very new to this and just like to offer what i know. i run spl drag and sound comps most amps work like this the lower the oh
rating the more of its availa le power it will use for i stance my amps are half ohm stable. then i could run a dvc 1 ohm sub at full wattage but if i where to hook a si.gle 4 ohm sub. to it it might actually use less then half of the available power. ohms are super important. if u have a one oh
stable amp u want to. buy speakers that give u the ability to wire down to one ohm. upgrade all wiring. fro. alternator to battery from battery to ground. higher amp alternator. it all makes huge diffrences in spl. im proud to say i have a single cab truck that hits. 139.7 dbl. good lu k in ur ventures! go big or go home! lol

Ok in what situation would u use a series connection for our trucks??? My guess you would have to run own wires for door speakers to get series conncections???

Woofers would be the other setup that would be series connection idea,, if you have more then one speaker.

 

You run series or parallel depending what ohm load your speakers are rated at and what load you want the amp to see. It all depends on both of those things.

 

basicly it depends on how much work you want to do!!!!! along with what you say.

 

It has nothing to do with how much work you want to do. It's all of like a 5 minute swap to change subs from parallel to series. And door speakers you really don't have much of an option considering each of them get their own channel on the amp.
