This is my 2nd tube. My first was an amplified 10" 250w and now an amplified 8" 250w. Installation was very easy; I had my amp wiring ran from a previous system. System arrived as stated and in working condition. I installed the system under 20mins (amp wires already installed.) I tested the set up and it worked. I noticed the bass wasn't what I expected from a bazooka tube. I messed with the tuning on the radio head. The Subwoofer was out of phase so I reversed the phase and it began to hit hard. I attached my radio settings and now it hits hard. If you install it yourself and not totally sure how to tune it, take it to a professional and have them tune it. Attachments are uploaded in order

They are pretty good for the money, but do not compare to a quality amplifier with a quality subwoofer. They are perfect if you're looking to add a little bit of low end depth.

Very easy to install with the kit provided. Four connections: the ground, the power wire, the remote power and the Rca speaker plugs went directly into the rear of my stereo deck. Very easy to install and sounds great. Ads thump to factory speakers and aftermarket deck. Nothing crazy to rattle the car, but plenty of bass to my system that had none before, great price too.

Received the Bazooka BTA850 on October 10, 2016. The product stopped working today, November 22, 2016. I have mixed feelings about this product. I ordered this to replace my Bazooka BTA from a couple of years back. I owned for nearly 3 years. It added joy to my MKT. It still works, but the end with the amp has come loose and there's a terrible rattle with the product. So, I ordered another one. It stopped working!! The first one lasted a couple of years and the second only a couple of days. Ugh!!!! I miss my sound. Now, you can see why I have mixed feelings about this product.
Now, I must address Amazon. I called today and explained what happened. Amazon opted not to do anything at first. I am a loyal Amazon Prime member. I shop Amazon for mostly anything I need. I've only had 2 or 3 issues over nearly a decade. I can't believe the product just stopped working. I guess after explaining my dissatisfaction they described to take care of the situation. I really mis my sound though. Ugh again!!!

This is a GREAT product! If you can spare a little room in the back of your SUV or trunk of your car it's a no brainer. Installed myself in about an hour and it sounds amazing!!! If you just want to add some great low end to your stereo, this is for you. Even better if you have an after-market head unit that allows you to control the sub separately. Either way the sub has a manual adjustment on the unit itself.
