WHAT?? i need help

[ballisticBaller 10+ year member]

 

ok im really new to car audio so i need alittle bit of help

i have 2X12'' polk audio subs

they were run by 500 watts but the amp died out on me

 

im running with 8 gauge wire and rockford fosfate (or whatever) RCA cables

 

i dont know what rms is

i dont know what they do i dont know what ohms do

all the tecknical stuff thats abriviated....(ex rms) i have no clue what they are what they do and what not to do with them. im new to car audio like i said and i want to figure this stuff out

i want my subs to beat hard but have a nice quality sound to go with them

 

PLEASE help me

up your power wire to AT LEAST 4 gauge..

what model subs and size? we need specs.

RMS is a power rating (like PEAK), mesured in watts, that is a thermal rating of how much continous power your subs can take, day after day (daily).

PEAK (or MAX) is the maximum amount of power (in watts) a speaker will handle for ONLY a split second.

The RMS and peak ratings on an amp are the same, MAX is how much power (watts) it would put out for a SPLIT second before "dieing". RMS is how much power (watts) the amp can put out continously, day after day (again, daily).

RMS is the rating you should go by. Match a subs RMS rating to an amps RMS rating.

--------

Ohms, is a technical term to describe how much resistence the speaker has against power.

Ohms (For the purposes of this thread) is generally used to get a specific power out of an amp.

For example, an amp has these specs:

300 RMS @ 4 Ohms

450 RMS @ 2 Ohms

800 RMS @ 1 Ohm.

By getting a sub that matches the amp specs above, it will produce that much power at the ohm rating.

I have tried to make that as simple as possible.

Hope is helps your understanding on the those terms.

ok then , what are channels on amps and what do they do, how do you use them and is it ok to run my 2 subs on different channels. also i just picked up a passive crossover for really cheep from a friend. it cost me next to nothing. what is it and how do i use it???????

channels are where you run your speakers from the amp. there's monoblock, 2 channel, 4channel, 5channel and 6 channel amps.

they give power to the speakers.

you hook up the speaker wires from the subs to each channel (unless bridging).

i wouldn't recommend using a passive xover on subs. (has pre-set cutoff frequencies).

as for running subs off each channel, it depends on the subs impedence, and the amps load stability.

what doi each channel do, like whats the difference in mono 2 3 4 5 6 channel?

when and where do i use them?

ps this is helping alot

each channel pushes out power. the difference between the different channel amps, means you can hook up so many different speakers to that amp. they all push power.

what do you mean "where do i use them?"? you use the amp in your car (you CAN hook it up in your house as well).

seriously tho, check out this site and read there for a good week or 2:

http://www.bcae1.com

that will be your best bet for everything you're asking. we're not here to spoon-feed people.

if you can't do some research yourself, then we can't really help you.

just start reading there. if you don't understand something there, KEEP READING, it may be answered later on somewhere else.

thanks for all the help

"wher do i use them"

whats 2 channels vs mono. i got my subs checked out at the local car audio place and they said the best bet for my 2 polk audio 12'' 1000watt subs was a mono no 2 channel amp

mono means all power is put into 1 channel (usually class D monoblock which are usually 75-80% efficient).

2 channel usually means you can wire 2 subs to it, but may not be 1 ohm stable like monoblock amps are.

all depends on the vc configuration of the subs and power demand.

vc?

 

[dkguitarist 5,000+ posts]

vc?

vc= voice coil configuration i.e.

svc 2 ohm

svc 4 ohm

dvc 2 ohm

dvc 4 ohm

quad .7 ohm

dvc 1.5 ohm

etc.

the IMPEDENCE of the sub.
