Better than no sub at all
Crutchfield Customer Review (What's this?)
I am glad that Retrosound makes this powered sub. With the space I have in my classic truck, it was the only real alternative to have a sub at all. But it is not a great subwoofer. Since the enclosure is so small for an 8" it does not get the big booming sound I'm looking for. The 100W amp does not put out as much power as the 50W amp I have in my other car with an 8" standard box. The sub also rattles in a heavy bass track and that is rather annoying. The 6X9 speakers I installed at the same time are putting out the majority of the bass power. If you are really cramped for space as I was, then this is a reasonable alternative but if you can find a way to install a traditional separate power amp and an 8" in a speaker enclosure then I would do that.
Pros: Fits in a small space.
Cons: Not a great warm sub sound and low on power for a 100W amp.
