I purchased this sub about 7 months ago as a replacement for my blown hifonics sub. The difference is amazing. Just the weight of the magnet alone was nearly doubled compared to the cheap hifonics sub. It hits hard, clearly, and accurately. I only have it hooked up to a Kicker ZX300.1 amp and this thing really puts out the power. With the gain only turned up between halfway and three quarters, it makes the hair on my head stand whenever I pump out tunes. It's very good quality and made exceptionally well. I purchased it for $80 from s
SonicElectronix and I can say that I will definitely buy from them again. Shipping was very quick as well!

these subs are awesome i love them i've herd many subs before and ive installed several different brands and so far i like the alpines the best a friend of mine bought a set of the Type-R's and they were insane i couldnt even stay in his truck when he would turn them up. they wer a bit much for me so i took it a step down with the Type-S's and im still extremely impressed for only being 300 rms each there awesome and they take one HELL of a beating i have them in a sealed box hooked up to a 900 watt rms audiobahn A16000V at 4ohm and they POUND!!!!!!! i cant turn the gain up more then a 1/4 of the way cause i cant keep my rear view mirror on lol i would recomend these to anyone looking for a great sub at a great price. i promise if u have these things hooked up to a good amp you wont be disappointed

Amazing sub for trucks had two of these in a single cab s10 and it was loud enough to flex my wind shield a little for not even breaking the hundred dollar mark these are by far the best for the money truck subs around for cars however I would recommend upgrading to type r's both however are very very good subs.
