Subwoofer is very quiet

[Emanuel Rodriguez]

Hello guys, I just installed a brand new sundown sml-12 with a Recoil Red600.1 amp from Amazon. I turned the sub on and it sounds very quiet compared to my brothers smaller 300w active subwoofer. The sub is in its proper box so I don’t know what the problem is. Can yall give me ideas on what to check?

Have you set the 'gain' knob on the amplifier? Set it correctly?

Yes I raised it up all the way and messed around with it and it still sounds muffled and quiet

Is it connected to an OEM radio?

No I have an aftermarket stereo and I turned on subwoofer from the stereo

I have a 08 Silverado. The box and sub are under the rear seat in the passenger side. The sub is facing upwards

Looks like a D2 or D4, did you wire the subs down to 1 Ohm ?

It’s a d4 and I wired it down to 2 ohm

 

[5t4y_50L0]

Amp is 1 ohm stable

Yeah but I can’t wire a single d4 sub down to 1 ohm. If I had 2 subs it would work

Nvm, I misread

• Peak Power at 1 Ohm: 1,000 W x 1 Channel (14.4v)
• RMS Power @ 1 Ohm: 660 W x 1 Channel (14.4v)
• RMS Power @ 2 Ohms: 520W x 1 Channel (14.4v)
• RMS Power @ 4 Ohms: 310 W x 1 Channel (14.4v)

So you have one sub
Sundown SML 12
The correct enclosure
(??x??x??)
Enough power
Recoil red600

But the subwoofer is not performing?

Exactly what’s happening. It sounds very muffled like if it was underwater. My brother has a smaller 300w subwoofer and that one sounds louder and clearer

What's the specs on the enclosure? Cubic feet, and sealed or ported ?
