These little guys are awesome. The magnets are HUGE. I actualy had to fight when installing them to keep the magnets from jumping to the metal of the door. The speakers are well constructed and sound awesome. Be aware that many cars will require a mounting bracket.

Great replacement

The following review is for 08KS400, which is a part of the bundle you are viewing.

Great replacement 4" speaker. Didnt expect much from such a small speaker, but these are much better than I expected!

Good sound great value

The following review is for 08KS400, which is a part of the bundle you are viewing.

Needed a stock size replacement for my 4Runner's in-dash speakers. These had the best materials for the price and I still like the way they sound for 4" speakers; They give about as much quality sound as you can expect for a speaker that size. Extremely easy to install, did it myself.

Big things DO come in small packages!!!

The following review is for 08KS400, which is a part of the bundle you are viewing.

I purchased these speakers to replace the 4" speakers in my boat, thinking that I'd get my $'s worth if they lasted a couple of years in a marine environment. These speakers are phenomenal!! They are a perfect front stage speaker (w crystal clear highs) for a system with either a sub or larger rear speakers. I decided to isolate these speakers (hooked up to deck pwr) from my system to believe my ears and wow, they sounded like a 6 1/2" speakers!!! I wouldn't buy any other 4" speaker after owning these.

Very surprised!

The following review is for 08KS400, which is a part of the bundle you are viewing.

I ordered these speakers because they were cheap and my front speakers were blown out. I wasen't really expecting to much. But i am VERY happy with them. The highs are amazing, and the mids sound good. And they get pretty loud to.

I've had them for about a year now, and the only thing is one of them started to crackle at high volume but stopped doing it recently. I think its because they got wet being where they are located in my door.

Overall I'm very happy with them, and would recommend them to anyone looking to replace their stock 4" Speakers.
