Need help with sub/amp setup

[Qmobile]

I gotta 12 inch sub that has:
200 watt RMS
400 watt peak
Single 4 ohm Voice coil

It's gonna be in a sealed box also. My issue is how big of a amp will I need? Lookin for something that'll work w/o blow up lol

[Alien Mantis]

You could tell us what brand/model it is. That would be helpful.

What size sealed box you going with?

[Qmobile]

Directed is the brand my sub is from it's eXtreme line model number 124SX. the box i'm not sure of the size but it's just a generic Scosche 12" box

You need something like this:

[Qmobile]

Price range ?

[Qmobile]

nothing too expensive >$100

[Alien Mantis]

ok any other options?

You could go with this one, but you can't crank the gain.
It makes a little more power.

I don't recommend BOSS, SSL, JENSEN, HiTron, Power Acoustik, etc.

Cheap amps tend to run hot and they don't last. They also produce dirty power.

Class D is nice for subs, and those amps are all a little over $100.

Buy a Boss or SSL for $70. Nothing stopping you. It should technically "work".
But most people on here won't recommend it.

So here ya go, if this is what you want:

well there is some wiggle room 2 I like that kenwood. But back to my what's the least amount I'd need to push the sub?

[willygoodness]

any brand that says output of 200rms @4ohms and you'll be fine and i'd say happy with.


if u don't want to put the volume button up to full on the amp. get a 300wrms @4ohm amp.

if u get a 2ohm or a 1ohm @200rms amp, it won't sound as clear. as the sub is for 4ohm.

i've got 2x 4ohm subs. but if i run both off the same amp at 2ohm it gets louder. but not as clear... if that helps u

just don't turn up the subsonic bass knob, that's IMO the thing that blows subs

had one for over a yr and still works with rough install

Don't ever use the Gain/Level knob on an amp as a Volume. When i get to a computer later on i'll post some info Qmobile. Alot of the feedback you have received is False.

Here's an ok amp with room to grow. Would i buy it. No because i can get about Tripple the Power for that price. I wouldn't recommend the amp i use because it isn't efficient for a newbie (no offense). The amp kit you'll need will cost about 60 bucks. Upgrade your battery. Big 3. So you're looking at about an additional 200 bucks.


So to be efficient on your battery i'd stick with the Best Buy brands. Which is "okay". Kenwood , Fosgate , Alpine, Pioneer.

ok thanks! I'm lookin to get a MEI DA8275 300 watt amp 2 channel 4 ohm amp. Know anything bout that one?

[_S7V7N_]

Amp is Probably about 15 years old ? MEI hasn't been around for a while.

Amp probably does 75 watts RMS

15 bucks at the most for that amp. Same category as Jensen or Boss.

[Qmobile]

ok I thought it was 2 good 2 be true. The guy is askin $35 for a amp from '95 seemed a bit extreme 2 me

[Alien Mantis]

Hey Seven,
He doesn't have to do the big3 upgrade. He's runnning a low power system.

He asked what is the minimum power he needs for that sub he has.
I would say 150watts RMS at 4ohms.

An 8ga amp wire kit will work fine for that.

[Qmobile]

So Alien Mantis,

the MEI amp what's your view on it?

[_S7V7N_]

I was stating why i recommended the amp but wouldn't purchase it. At this time it's more cost efficient to go with an entry level amp that is a bit more efficient on the electrical system as well.

The amp i had (sold it ) did 1500 watts rms @ 1ohm. It goes for 120 bucks. You need good electrical cause it has the potential to draw about 100 amps of current.

@Alien Mantis. Define "Dirty Power "

That amp will do 1400 clean 1500 and then some Dirty. Which is fine for burps.

[Alien Mantis]

So Alien Mantis,

the MEI amp what's your view on it?

I'm sorry, I have no experience with that brand.

:iono:

Oh, I totally agree.



@Alien Mantis. Define "Dirty Power "

The cheaper amps seem to run hotter and they have a poor signal-to-noise ratio. Not all, but some do. Can't trust the specs on the box either, the manufacturer can fudge the numbers.
Like with subs. Cheap subs that have weak motors will be rated at 1,500w max power. That is maybe for like a split second at a specific freq range!

All kinds of marketing tricks. You know this game, you get what you PAY for.
The "good" stuff will cost you.

[Qmobile]

well considering this is a cheap sub.... I don't really need a fancy ex$pensive amp. I seen one today in town for 55 i forget the brand but it mite work

[_S7V7N_]

Alien i wont go any further off topic but you'd be suprised how many of them cookie cutter name brand "good " subs and amps are built by the same build houses over in Korea,Japan,or China. Some get a Soundstream logo others get a Power Acoustic Logo. Hell do enough research and some may get an Alpine logo !!! If you opened up 10 diff Manufacturers amps, you'd be suprised what you'd find inside and who shares the same boards.
