P2D4-10

Two of them in 06 impala sounds good deep bass

Great subwoofer, it exceeded my expectations. At first I installed it inside an Atrend sealed Bbox, which is. 85 cubic feet and within Rockford Fosgate's specifications, it sounded ok since I installed it inside my trunk. However, I wanted more bass using the same sub so I opted for a ported box instead. Thus I purchased a Sound Ordinance box from Crutchfiled. It has 1.4 cubic feet of internal volume the recommended space from Rockford when using ported boxer. This box was the only one with the correct internal volume I could find in the internet. Once I installed it, wired it, and played some music, I immediately noticed the difference. The P2 hits harder and with longer deeper bass notes I can now feel inside my car. My Alpine amp is tuned to the same settings as with the sealed box, but the sub is louder, because power efficiency is better achieved with ported box. So long story short, if your mounting this sub in a sealed trunk like mine separated from the passenger compartment go ported with the recommended internal volume. If you however, drive a wagon like a Scion Xb or something similar, a sealed box will hit hard and you'll feel and hear it. I recently installed a 10 inch P1 in my wife's Xb using my old Atrend Bbox powered by an MB Quart 400 watt rms monoblock and it sounds stupendous. Well I hope this helps and you are able to come a conclusion about your purchase and how to install this great sub based on your application.

I purchased one of these 2 years ago to go with a Memphis 5 channel amp that puts out 400w to the sub channel and mounted the sub in a custom fiberglass enclosure that is right at 1.0 cu ft air space. (which sounds better than the .7 I had) this sub still sounds fantastic! I've been building car audio systems for over 20 years and have installed and listened to just about every subwoofer out there and I have to say that this sub performs with the best of them. It puts out the bass of a high end 12" woofer and would honestly imo out perform two mediocre 12s. Not to mention this sub looks fantastic when installed. I would definitely recommend it.

It works fantastic but I wish it came with a metal cover. I had to purchase that separate.

High quality as you would expect. This Sub does the job without ever breaking a sweat. One time investment with a lifetime of satisfaction.

I bought this subwoofer to replace my blown bazooka subwoofer which had 150 rms wattage and 500 wattage peak. Because I have 300rms wattage to 600 wattage peak amp, I thought about this subwoofer as replacement and upgrade. Presentation of this subwoofer was okay, didn't really blow me away, but the product itself felt durable and well-made. One little perks I found was that mounting bracket for the subwoofer didn't match the bazooka's basstube screw holes. So I had to create additional layer of larger screw hole bracket for the subwoofer. After the install, and listening to this product, I found that bass to be more punchy and loud (which is great for me). But found little issue like not able to reach certain notes at high volume or low notes on certain songs. Something you can acommodate by having dual subwoofers, but I am fine with single subwoofer for my little hatchback.

I have a 2005 Chevy Silverado regular cab and built a custom down firing enclosure to replace the bottom section of the center console/seat. It's right under 1.5 CF and originally I had a JL10w6V2 in it. After an unfortunate incident with something getting wedged between the floor and the sub I needed to replace the JL. I run a 5 channel amp with 275 watts to the sub. I have to admit I am impressed with this sub. It hits as hard or possible harder than the JL it replaced. I could not be happier. Easy to install and it was very easy to wire for 2 Ohm. Might pick one up for my Jeep next.

Exelente producto, entrega 100% rápida antes de lo esperado, personas responsables, los recomiendo totalmente

Replaced my old 10 inch sub. Punchier and deeper than the older model

Wie erwartet, gut. Ist Ersatz für den Lautsprecher in meiner Swissonic Sub10 Box geworden. Positiver Nebeneffekt, der Verstärker wird nicht mehr so warm.
