Sub install

The following review is for NSW82v3, which is a part of the bundle you are viewing.

Great bang for the buck, wired @2ohm to the amp, 500 watts rms, for 2 8 inch subs they hit really hard, great for a quad cab truck

Looks good, sounds good at a good price

The following review is for NE81P, which is a part of the bundle you are viewing.

I'm not an expert, but this enclosure impressed me.
Nice, black carpeting... Lettering is matte black, not blue like the online pictures... Which is better IMO. Enclosure has some weight to it, which makes it feel heavy duty.
This enclosure was the perfect volume size for my P3 subwoofer, and it sounds great.
If I could improve on this box, I would say the terminals could have been installed more straight instead of at an angle. It also could've been installed more toward the bottom. But those are minor gripes. I'm happy with this box and what I paid for it.

Insane amount of bass for this price range !!

The following review is for NSW82v3, which is a part of the bundle you are viewing.

Absolutely in shock on how much bass this little woofer puts out in a custom built ported box i would highly recommend this subwoofer especially for the price range

Incredible 8's

The following review is for NSW82v3, which is a part of the bundle you are viewing.

These truly are the best blend of SPL and SQL. Running a NVX 1500.1 along with a NVX 1 Farad cap and couldn't be happier. Built a slot ported box at 2.3cu ft with a 34" port wall tuned to 36Hz. Look forward to adding similar setups to my other vehicles.
