The shallow mount was an awesome idea for me because I have a small truck. I have it behind my passenger seat on the floor board and it works really well. I recommend this product to people who have small cars or trucks. Despite the fact that it is a shallow mount, it thumps pretty hard!

I have 1 of these in a frontier behind the seat. Had a cheap box, changed it and now it is unbelievable. Blowing away a normal premier series sub. I would recommend for every one especially if you port the box. Great bass has heads turning!!!!!!

I have two of these in a 03 f150 under the back seat, powered by an Alpine M500 with a line driver and a capacitor. It hits the highs really well although i wish it hit lows like a deep sub. Would definantly recommend.

Customer Testimonial

First time buyer with SE and let me say that all my expectations were met. I wanted a CD receiver for my Father's car and SE came thru for me. Was very happy that SE included the Installation Accessories. I honestly didn't expect that.Thank you SE for the great updates via e-mail. Top Notch Service.
