Our take on the Blaupunkt GT Power 54.2 c

Why listen to your old factory speakers when a nice upgrade is within reach? Blaupunkt combines its reputation for reliability with modern design in their GT Power Series speaker line.
The GT Power Series 54.2 c component speaker system features 5-1/4" polypropylene woofer cones that deliver accurate, full-bodied sound. Separate Mylar semi-dome tweeters reproduce the vocal and instrumental details smoothly and cleanly. The 3-ohm impedance safely draws a little more power from your car radio or amplifier. And the signature blue color offers a look as distinct as Blaupunkt's legacy sound.

Good but not very loud

Crutchfield Customer Review (What's this?)

I'm pretty new to the stereo world. There's nothing about these speakers on the internet. So I thought I'd take a chance on them. They sound great! Very very clear. They give off a little bass. It's enough to make my side mirrors shake. I have practically no distortion now with any type of music. When I listen to Rock none, Metal none, even Rap or R&B there is none to be heard from these speakers. I replaced one door to hear the difference between these and my stock speakers. The difference was incredible these were so clear. Compared to my stock component speakers. The major this I noticed that I don't like about these is they're not as loud as the stock speakers were. So you're basically trading quality for volume. Installing was a bit of a headache at first the instructions weren't very clear, and they give a lot of extra wire so be prepared to to a little bit of altering if you don't want a lot of excess wiring. i give this only four stars because of the fact they're not as loud as stock speakers are and installing was a bit of a headache.

Pros: Crystal clear sound! Looks awesome!

Cons: Not as loud as the stock speakers were and installing was a headache
