Summary: Needed to add a new head unit to the 4Runner my son will eventually take over. I still drive it from time to time and miss the true bass I have in my car with subs and amp. I had a spare amp and decided the passive dual voice coil box would be a good match.
Pros: Clean low end extension without being exaggerated (unless you want it to be); easily integrates with an existing system.
Cons: Probably needs to be anchored down if placed in the back storage area to prevent movement; it does come with a strap for this purpose.
Conclusion: I do recommend this speaker tube if you are looking for a nice and solid bass for a cheap price, I bought mine because of the box itself I knew that the original speaker wants going to perform good with my amp, so what I did I removed the original speaker and replaced it with a more power full one...
Conclusion: Instead of putting a wedge truck box with 2 10's in the back of my regular pick up truck which take a lot of room, I just slap a 10dvc bazooka bass tube in it and it save me a lot of room. Also it sounds great and it doesn't require a big power amp to run it, promlem solve.
Conclusion: I just got this 10 for my 2004 Tahoe and powered it with a 300 watt rms amp and this thing pounds hard , sounds clear ,good bass. I had a big box with 2 10 inch subs and it did not hit as hard and clear as the bazooka.
