THESE SPEAKERS FLAT OUT ROCK !

The following review is for NSP35, which is a part of the bundle you are viewing.

My experience with Sonic Electronix has been excellent ! The NVX product line is a fantastic value and the performance rivals products 3 times the cost.
For 3.5in speakers these things are amazingly loud. Awesome mids and tweeters that will blow your mind. The front staging in my audio system is better than I ever could imagine due to the fantastic performance from these speakers. Top notch build quality and materials, for $30 they are a super value. I am buying another pair to run in my rear deck. I will say it again

Awesome Value

The following review is for NSP35, which is a part of the bundle you are viewing.

These might be the nicest three and a half inch speakers available. They are certainly of very good quality and they sound great. Produce very realistic and clear sound quality.

Great speakers!

The following review is for NSP35, which is a part of the bundle you are viewing.

I put these speakers in my fiance's Mini Cooper S because the one's that were in there sucked in the high's department! I was impressed with just hooking them up to the stock HU. I can actually here what people are saying and singing without having to crank the volume way up. I'm gonna get some more for my 4Runner for highs now!
