O2 OW15 15inch. Subwoofer, Dual 4 Ohm Voice Coil (O2 OW-15) (Single Piece)

Love this sub. It not only looks good but it sounds great!! I have this sub housed in a QPower Single 15" Vented unloaded box. The amp I'm using is not keeping up with the power needed to keep this sub happy so, Make sure that your amp will push roughly 700 to 800 watts "RMS". This sub has 2 4Ohm coils so, You'll need either a mono amp or 1-Ohm stable amp if you have a 2 channel amp. Thank youUpdate: I liked this sub so much, I purchased another and a sealed enclosure as a ported enclosure would not fit my 2014 Mazda3 5 door. I'm running them at 1-Ohm 1,054watts and they still look for more power. Great subs for the money!!! Thank youUPDATE: I've had two subs for almost 2 years. They sound better and better as they are being used. Beautiful sub!!Update 2: It's been over three years now. They are still working great!!! Too bad they are no longer producing these subs :((- Thank you

Loose cone.... You get what you pay for

Awesome sound , look, construction, and all around value these speakers poped a brand new box on day one at half their RMS ,these speakers are way underrated i t says1400max and I'm pushing 2300wmono@2ohms through each speaker and I honestly feel like they could take a lil more but don't wanna push it already 900watts more than the manual states. I've owned several pairs of15" subs and these hit harder than any I've previously owned, aluminum cone ,thick rubber surround, machined aluminum all around construct, and a high quality large magnet. Thinkin of purchasing 2 more #93grandmarquis wit kingkong in that trunk

Tested them out on a 1500.1 audiopipe amp and they held up for 4 months. The loudest hitting sub for a low low price. I recommend these to anyone.

Excellent build quality and they sound amazing. Just got mine today. I just wish shipping was quicker!

I got to said if u thinking about getting this subwoofer go for it is great sounds great I got to give it 5 stars love it.

Worth every penny
