amp question

I have 3 150 rms 400 watt peak 10" rockford subs. I am having trouble finding a mono channel amp for them because most would overpower them and then burn them out....Is it possible to use 450X1@4 ohms and then loop my 3 speaker wires together sending 150 rms to each or is this impractical? Rather than paralleling and having 1.33 ohm which is hard to find a 1 ohm stable amp that is not expensive. Any suggestions?

Lanzar amps are they any good I found a 4 channel running 125 rms and 300 max per channel....

Like I told you before, 50 watts over the limit won't burn up the speaker unless you're a complete retard, in which case you would burn up the speaker with an amp rated at exactly 150rms anyway. Get the JBL

Lanzar is bargain bin trash, especially their lower lines, and powering 3 subs separately on a 4ch amp is straight up ghetto ;)

well finding an amp that does 400-500 watts at 4 ohm will cost you ALOT, my suggestion is to get the HIFONICS BRUTUS BX500D, it makes 500 rms at 1 ohm, its a real value it only cost about $175 (shipping included) on ebay, i am going to get the higher models tho, probably the BX1000D/BX1500D

and overpowering your subs a lil won't hurt, just be smart about it, dotn do obvious things like turn the gain all the way up, or the bass boost, or put it in a rediculously sized ported box, i had an alpine type R before, i used 400rms on it, but then again the gain wasn't all the way up, and i know that the type R can take more than 300rms

Forgot about this when I responded earlier.....


Not only is this impractical, it's simply impossible. There are only 3 ways to wire your speakers together, no more, no less.

1 - Wire them together in parallel, this will show the amp a 1.33ohm load and you'll get the 1.33 ohm power going to the set, 1/3 of which will go to each sub
2 - Wire them together in series, this will show the amp a 12ohm load and you'll get the 12ohm power going to the set, 1/3 to each sub.
3 - Wire them individually, this will require 3 separate amps. You could use 3 channels of a 4ch amp, but that is so insanely ghetto I don't know where to start.

I don't know what you're talking about "loop the 3 speaker wires together", when you attach the speakers together you are either attaching them in series or parallel, that's the only way you can possibly wire multiple electronic devices together. Depending on which you choose (series or parallel), the final impedence is either the sum of the individual impedences (series), or the inverse of the sum of the inverses of each individual impedence (parallel).

get a big class D amp ....... you can easily double the woofers RMS ratings if you set the gains right
