Do I get a more powerful Amp or less powerful?

[JasoninDLH]

I’m contemplating a Dual 4 ohm Voice Coil 400 watt RMS 12” Phoenix sub.

Do I use a 300 Watt 2 ohm amp or a 500 Watt 2 ohm amp? Or is this just “half a dozen of one and six of another?”

If the sub is a 400w rms sub then 600-800w rms amp. Set the gain correctly and have headroom without distortion.

Sounds great! There’s a nice 600 watt amp that will fit the bill. Thanks!

Is this for the Jeep? If yes, did the JL setup already lose it's shine?

It is for the Jeep. I’m loving the JL Audio Stealth Box. I’m just a bass junkie. I was going to add a 15” Square Kicker sub, but didn’t want to lose the cargo space. The 12” sub mounts to the tailgate and keeps it out of the way.

Ahh, the infamous rabbit hole people speak of. Welcome, to mount Wannahawkalugie!

Car go road. Car no go space.

So, are you adding an extra subwoofer. Different brand, size, box size with a different alignment.

Not all frequencies are going to be reproduced at the same time with the same intensity. This will cause destructive interference.

You're going to have a system that sounds really bad with some songs, and does ok with others.

I never thought about this.
