Summary: Purchased 2 of these installed in a sealed box. they were very loud for about two weeks. these are made to be run on 4 ohm not 2 ohm loads develope to much for these. i run a 2 channel 1000 rms. had the amp set at half way and was playing a bass track woofer blew 30 seconds into the song. if u are a bass head get some real subs. if u just want a lil bump these are ok. these handle around 300 rms around 500 peak.
Summary: This sub is awesome when I opened the package it looks awesome from the back it almost seems like a waste to put such detail into the back of the speaker that you mostly do not see. But this sub is actually a quad voice coil and it took me about two hours to figure out how to make it work. I know that if you Google QVC subs the next one is over five hundred this sub is a sleeper and I am gonna buy 1 or two more to compliment my system.
Summary: i bought two of these subs and a lanzar vibe 292 amp and was also running 2 rock ford tens off one amp and ran them for about a month and both of the 15 over heated every time i played them loud and now they have both blown i would not recommend these subs if u are looking to play them with any power to them they will over heat and fry.
