Help with Amps and RMS???
|
New member Username: Ulshy55Post Number: 1 Registered: Jan-07 | Ok, i just bought 2 10 inch MTX subwoofers in a box. It says 400 RMS on it. So how big of an Amp should i buy. I really don't want any chance of blowing these subs, but i do want good output. They are in my trunk. And does the power chord matter? I already have one from a previous amp (500 watts) would this one work with whatever amp you recommend? Thanks in advance. |

I'll check if there is a sticker somewhere, but i don't think there is one. the guy at the store said a 700 or 800 watt amp should do, but i wanted a second opinion, and i really don't want to blow the subs. |

I did look at MTX amps, but damn they are expensive! I am looking for one that will power the subs for 150 or less. Preferably less. But if that is not possible please recommend another. Thanks |

Silver Member Username: Nickb4247Post Number: 107 Registered: Dec-06 | That link leads me to believe that the loaded boxes impendence is 4 ohms. If this is true and those subs are SVC like I think, then they are either 2ohm wired in series or 8 ohm wired in parallel. Most likely they are 2 ohm, so you best bet, if it were me, would be to re-wire the subs in parallel for a 1 ohm load if possible. And get a kicker Kx400.1. To be sure, remove one of the subs. Each sub should have ONE(if there are more, then they are dual voice coil) set of hook ups(+,-) on them. On the back of the sub(on the magnet) it should tell what the subs impendence is in ohms. Give us this info to be sure. If they are single 2 ohm, I think the option above is your best best. If they are each single 4 ohm, you would still wire them in parallel. But you would need an amp that puts out around 400 watts @ 2 ohms. |

Silver Member Username: WarlokOrlando, FL USA Post Number: 151 Registered: Dec-05 | A website says these subs are "4 ohm (Dual Coil)". But more websites say SVC 4 ohm. |Seems to be a semantics issue, they can both mean the same thing. However, this not being a vocaulary game, One site say 200 W Peak and the other 400 Rms. Either way you look at it, its bogus. Most sites say SVC 4 ohm and 400 RMS, so I guess go with that. Means to you, you should go 2 Ohm Bridged. And no offense, only keep in mind what NICK said, not me, cause my name is Nick too, just dont confuse with the other guy, not that he dont mean well, but the advice given to you were based upon assumption that are not the case. Although I give em credit, non of his advice was faulty, just not relavant to your case. Since the are SVC 4 Ohm, you can parallel them for a 2 Ohm load, and get an amp that puts out about 700 - 900 W at 2 ohm mono. Cant really go wrong with that. However, I would do as Nick suggested and have a look for yourself, cause google seemed flaky when it came to gettin info on these puppies. .. .  |
