My new Sub set up! - Tilted Forum Project Discussion Community

Scorps · 06-11-2005, 07:13 AM

Well my old JL's weren't doing it for me so I got a new amp and new subs total power is 1200 watts

I got:

Amp: MTX- MXA 4001

Subs: Twin 12 inch MA Audio (ported box)

I could put more power to the subs but the dam plastic glass cover viberates liek a bitch, but if I do blow these subs I stickin 2 12 inch Rockford's in there

Quick pics as I was waiting for the oil to drain

Thats actually a bandpass box you have them in. The woofs sit in a sealed enclosure and fire into a ported one tuned to a very specific frequency range. They go super loud within the specified range, but have litte output beyond it. It is also harder to hear the woofers stressing because there is the "buffer" of the box to contend with.

Yeah, with enough power, sealed is the way to go. More accurate for sure.

Shoulda of stuck with your JL's and powered the shit outta them, JL like lots and lots of high wattage. Remember it's not how many watts you have, its how you power it.

Well I might have to get a new box because the damn glass cover is viberateing really bad now I can't seem to keep the screws tight!

Well the amp is 1200 watts and well them Jl's where maybe 400 max...so they would have blown big time!

merkerguitars · 06-13-2005, 08:05 PM

Umm 1200 watts...here is your amp specs..

Power Output:
200 Watts RMS x 1 channel at 4 Ohms ≤ 1% THD+N

Signal-to-Noise Ratio:
75 dBA (reference: 1 W output)

Additional Power Output:
400 Watts RMS x 1 channel at 2 Ohms ≤ 1% THD+N

Scorps · 06-14-2005, 10:34 AM

If the amp I got now is cooking the voice coils on 1200 watts subs, just think of what it would do to 300 watts!

brandon11983 · 06-14-2005, 10:26 PM

Power ratings really don't mean anything on speakers. I would feel safer running subs at 10,000 watts than I would 10 watts. With tons of power on tap you can never really ask for too much power out of the amp, as it will always have the headroom to deliver it.

Scorps · 06-15-2005, 01:32 PM

I got a question if I'm out down town and have the subs running for like 2 hours, is it right for the amp to get hot(not warm) to the touch and most of the time it shuts its self off?

How high do you have the level set on your amp?

cj22009 · 06-16-2005, 08:10 AM

Pain the gain is turned up to high drawing to much current thats y its shutting off on you turn your gain down

phathom · 06-16-2005, 01:20 PM

you probably have too much impedance on the subs, most amps are meant to run at 2ohms, you might have it up to 4 and it will power them for sure, but after a while it shuts off, that means it is going into thermal meltdown and is shutting down before it does, change the wiring on the subs to lower ohms or your amp will fry, trust me. it is probably as simple as unbridging them, or if they are dvc, changing the wiring setup.

I had turned it down to 3/4 from full, and turned the Bass Boost to half

But if I take the glass peace out will that make a difference, I can't seem to keep that damn thing tight it rattles like a bitch now
