Loaded enclosure options

[EricF]

Hey everyone,

I'm looking at a few different loaded enclosures for the trunk of my 3 series BMW. Long story short, the amp I was using for 2 12" Kicker CompR's in my other vehicle wasn't making the advertised power, so I had to upgrade amps. I'll be using this left over amp for my car. It's a DB drive WDX 1000.1, (1000 watts @ 1ohm, 500 watts @ 2ohm and 250 watts @ 4ohm rating). I'd imagine going for a 1-ohm subwoofer set up would maximize the output of this amp?

I'm going back and forth on these loaded enclosures. Given the option between an 8, 10 and a 12" set up in a trunk I've heard discussion that you should go for the biggest sub you can fit to maximize output.

Memphis mojo 8" in a ported enclosure (900 watts rms @ 1ohm)
Skar SVR 2 8" in a ported enclosure (800 watts rms @ 1 ohm)
Kicker L7T 10" in a ported enclosure (500 watts rms @ 2ohm)
Kicker CompR 12" in a ported enclosure (500 watts rms @ 2ohm)

I really like the Mojo set up due to its size and I'd imagine it must be on steroids for an 8" sub to have a power rating of 900 watts rms. As much as I want earth shattering bass I know I'll need to lower my expectations for any of these set ups. I will be sound proofing the trunk to minimize any rattles.

Looking forward to hearing some opinions!

Hey EricF,

You've got a solid set of options there for your BMW's trunk setup! You're correct that going for a 1-ohm subwoofer configuration would maximize the output from your DB Drive WDX 1000.1 amplifier. Your understanding of wanting to drive the amp at its peak performance is spot on.

### Subwoofer Size and Configuration

1. Size: Generally, larger subwoofers can produce deeper bass and handle more power. However, they also require more space and can have a different dynamic in terms of sound response. Smaller subs can provide quicker transient response and may perform better in smaller enclosures or tighter spaces.

2. Options Breakdown:
- Memphis Mojo 8" & Skar SVR 8": Both of these are impressive with high RMS ratings for their size. The Mojo, with 900 watts RMS at 1 ohm, suggests it could deliver some serious output despite its smaller size. This is great if you're looking for space efficiency and a powerful punch.
- Kicker L7T 10": This sub can handle 500 watts RMS at 2 ohms, which means it'll be slightly less powerful than the 8" options if you're running your amp at 1 ohm. The 10" size would give you a bit more low-end presence but at a reduced power handling compared to the 8" sub setups.
- Kicker CompR 12": Similar to the L7T, it also handles 500 watts RMS at 2 ohms. A 12" sub typically provides more bass extension but will take up more room.

### Recommendations
Given your interest in sound quality and potential for deep bass while still considering the trunk space:

- If you prioritize sound clarity and tight bass, the Memphis Mojo 8" is a fantastic choice. It's designed to perform well and should provide impressive output for its size.

- If you're looking for overall bass depth and volume, the Kicker CompR 12" would be your best bet. It will fill your car with bass and, assuming you sound-proof the trunk well, you could still get that rich bass experience without rattles.

### Soundproofing
You mentioned soundproofing your trunk which is an excellent idea. Using mass-loaded vinyl, butyl mat, or foam can help minimize rattles and enhance the overall sound experience.

### Conclusion
Ultimately, it comes down to your personal preference for sound: tight and punchy vs. deep and powerful. Make sure to consider your space, the overall sound you wish to achieve, and how you plan to utilize your trunk afterwards.
