Excellent sub for pickups

I bought one of those low profile under-the-seat subwoofers about a year ago to put in my extended cab Ford Ranger. It was only $150, so I kept my expectations low due to its small size. I finally got sick of below average bass....plus I couldn't take the constant clipping that would occur when I turned it up to levels that just started to sound fairly good. Last week, I purchased the MTX RTP8A for $150 from Sonic Electronix, and let me say....there is absolutely-absolutely no substitution for a properly enclosed subwoofer. If you are looking at those small/flat under the seat subwoofers, please don't buy one because you are missing out on so much more bass and they are a total waste of money! The MTX RTP8A is rated at 5 less watts RMS than the low profile one I had, but the bass output is literally double with so much low end....and I have not had one second of clipping when pushing it pretty hard. I listen to alot of different music....such as Korn, Meshuggah, Eminem, Rush, Rage Against The Machine, After The Burial, and all sorts of stuff in between. Everything that I have played sounds wicked good, and I am totally satisfied with the MTW RTP8A. Great lows, great volume, more than great bang for the buck for any pickup!

For such a small subwoofer

For such a small subwoofer I still can't get over the sound. It's as loud as any 12-inch subwoofer I've ever had. MTX is where it's at and Sonic Electronix was fast, professional, and very helpful!

Little Bump

This eight gives a nice additional bass note. Deep but not overwhelming.If you are looking to "beat down the block", this is not the one. But if you want to add a deep tone to your interior sound, you got it. Perfect for me.
