What kind of amp should i use to push two JL 10w0's?
 
The subs take 250W continuous at 4ohms. Would the same kind of amp be able to be used for a single 10w3? The double 10w0's and the single 10w3 are both 250W continuous, would there be any reason to use a different amp for either setup? Also, which in youre guys opinions would sound better? Im looking for a tight, clean, hard pumping bass. thanks!

the JL 500/1 is very tight

First off, the MTX in your sig would probably be okay - they're underrated. But, more power is always better.

For my two JL 10W0's, I bought a PPI PC1400 monoblock (400x1 @ 2 ohms).

150Wx1 would be enough?
 
that would only be 75W/sub. Also, is there a reason you went to overpower the subs by 200W? were there any performance gains? Thanks

Yes, it would, and here's why....
 
Your MTX amp is greatly underrated. Actually, it puts out 150x1 at 12.5 volts, I think. Since most cars run at 13.5, your more than likely pushing 250. In fact, go to MTX's website, and they quote the RMS rating at 14.4 volts at 325 watts.

Now, I'm not a big fan of this "dynamic" rating thing, but on the other hand, I wouldn't buy a new amp because of it. I actually considered your amp, but opted for a PPI instead - it was only about $40 more and is rated at 400x1 @ 12 volts.

Anyway, I think on average, you will probably be running about 250x1 (125 per sub) which is exactly where the subs are rated. Now, with the headlights, heat/AC, etc. pumping, your power will be less, but unless your cranking the system really high, I doubt you'll here it.

The only reason to "overpower" your subs, so to speak, is so that your amp doesn't need to work as hard at high volumes to produce good, clean power - which isn't always available at max volume - when your amp is on its "fringes" trying to supply power.

im not sure what the specs are saying though...are the website's specs RMS or Max power?
 
b/c if the specs are max power, the subs will be definatley not getting adequate power...however, if they're rms, then it would be fine.

btw, how do you like your double 10w0's? i cant wait to have mine installed! Thanks or your info!

jfabes 10-11-2001 12:03 PM

I, and another on this website, were discussing it, and think they are
 
RMS values. Max power, believe it or not, is probably more like 400 or higher watts. But, don't put any honor in that number. I would feel comfortable buying it and on average, expect to get 250 watts out of it.

I don't have my W0's in yet, but I'll let you know when I do!!!

rap413 10-11-2001 06:24 PM

Cool man. thanks for the info.
 
im going tommorow to the stereo hop to have them switch my single powerwedge 10w0 for double's. ill let you know how the mtx amp powers them. if it doesn't work im gonna be installing a JL 250.1 amp. so ill pot again tommorow and let you know how it works out!
