This is for the subwoofer only. It is a brand new SUNDOWN AUDIO dual 2-ohm SA series 2000 watts max subwoofer 1000 rms watts with a huge magnet and can take a ton of power. I only had it 2 days but it is way too much bass for my kids ears. This sub is heavy duty and very loud bass. I paid $320 for the subwoofer alone so this is a steal at $230. You can hear it play before you buy it because it is still in my truck until it sells. This is for the subwoofer only not the box. If you want the subwoofer and my tuned box that will be another $100. So you can get just the woofer for $230 or woofer and box for $330. Thanks for looking.
