Subwoofer & Amp RMS?

Question

Hi, i was just wondering if someone could possibly help me,
i wanted to get a 3000w amp for my car but iam having trouble picking my speakers, i saw a pair of JBL GT4-12 1000w 12'' subs that are 250w RMS and 1000w Peak Power.
My question is basicly: would this be ok to run? i want my system to be loud so thats why i have gone for the 3000w amp and 1000w speakers but its just the RMS iam worried about.
If somebody could give me some info then it would be much appreciated, iam very new to all this :) lol. thank you, regards

Answer 1

ditto to what sparky said.

look man. what you are supposed to do is buy subs first. after subs, buy an amp. so you know what RMS you need to match. buy the subs you really want and then come back and ask what amp you want with specs of your subs.

it is much easier to do so because matching a bought amp with subs is harder for some reason. it may sound simple, but youll end up buying something more expensive than you should pay.

so buy some subs, and if youre looking at those JBL's, get an amp that is a MONO BLOCK AMP that can run 500w RMS @ 2 ohms. So when you hook up your subs in PARALLEL, you get 250w RMS per sub @ 2 ohms. MAke sure your amp is matching RMS. Peak is almost NEVER reached. So NEVER look at the peak. Trust me. i started working with my audio installer and now i learned more than i already knew before.

So whenver Sparky or i post answers, listen to us please.

Typically you would match the total watts RMS of the subs to an amp. You also want to match the total impedance of the subs to said amp. Total impedance does not imply adding the impedances but rather calculating for different wiring methods. My site explains this in detail.

For best sound quality, I recommend two 4 ohm DVC (dual voice coil) for subs so you can wire them parallel-series http://i81.photobucket.com/albums/j230/sparky3489/PARALLEL-SERIES.jpg to have a resulting impedance of 4 ohm. I say this because loading an amp at lower impedances (less than 4 ohms) increases the THD (total harmonic distortion).

For instance, if you wanted 500 watts RMS for a system, then two 250 watt RMS subs @ 4 ohm DVC with a mono amp that's 500 watts RMS @ 4 ohm would be ideal.

Answer 3

Get a JBL 15" sub that can handle a lot of power (usually these speakers can take up to 5000watts). And then cross the wires so that you've got the entire amp powering that 15" woofer. People will hear your *** for miles away.

Answer 4

you are going to be searching for a six hundred Watt RMS amplifier it incredibly is nice at 2 Ohms. maximum mono block amplifiers are a minimum of two Ohm good yet be beneficial to envision. each and each sub will get carry of three hundred Watts. additionally, in basic terms look on the RMS score not the top or optimal means score.

Answer 5

do you have the amp yet? If not i would suggest you get with a professional. (Like myself 20 years in audio) And say this is my budget what are my options... I can help you pick out a system and get you a great price on it also...
