if you cant decide what subs you want and dont wNt to pay over 400 bucks get these

i have had these subs now for about six months Just got a capacitor for it and it sounds great. I bought both of these subs for about $200 great price. At B*** B** they are $*** each. So I'm hundred bucks off not bad. I wire these subs down to 1 ohm to a hifonic hfi1000d amp This app is perfect because it runs at 1000 RMS. I highly recommend you get a capacitor 1.5 fraud is good. I love them I Highly recommend them

I LOVE ALPINE SUBWOOFERS!!

I got this sub because it fit in my price range and I knew it was a good brand and I was familiar with them as well. I couldn't have picked a better sub for this price!! I absolutely love this sub! I love it so much I got my sister a type-E! Hoping one day to upgrade to a type-R, when I got the money. But this sub is GREAT VALUE! Looks awesome! 5 stars!

I got two of the sws- 12d4 with hifonics brutus 2000.1d two sets of kenwood kfc-x184c 6.5 components with tweeters on 4ch autotek ahl 1050.4 with autotek crossover system is hella clear i cant complain one bit im mean like they in the truck singing and playing instruments.....the bass hits hard but not as hard as it needs to cause the highs and mids are the strength to this system hits hard but i still want more bass deeper lows maybe ill just add 2 more since i was told the amp can handle 4.
