good speakers

The following review is for NSP46, which is a part of the bundle you are viewing.

I got 2 sets for my 1988 silverado and they fit with no problem and they sound real good and they look good.

Nice speakers for the price.

The following review is for NSP46, which is a part of the bundle you are viewing.

I bought these to replace the stock, blown dash speakers in a 94 Chevy 1500. They are a little too tall for the speaker grilles to sit flat (the tweeter sits above the speaker about 1/8"), and they slightly interfere with the passenger side defroster vent tube, but that's universal fit for you. They sound good considering they're powered by a stock 20 year old am/fm radio though. I would definitely recommend them as an upgrade from stock speakers.

Great Speakers

The following review is for NSP46, which is a part of the bundle you are viewing.

I have a pair of these in my 2003 Cavalier, they bolted right into place, and they sound amazing! Running off headunit, these and my 6x9 NVX speakers in the back make a huge difference over the original speakers! Very impressed with NVX, and will continue to buy their products

Sound great

The following review is for NSP46, which is a part of the bundle you are viewing.

They really made a great replacement for the stock speakers that go in the dad of a 2000 chevy blazer, and they are cheap, which was a plus. They are also low watt so you can run them off just a head unit.

good for the money

The following review is for NSP46, which is a part of the bundle you are viewing.

They're not gonna blow you away, but they're nice replacement speakers for the money. Just don't expect them to keep the bass coming when you really crank em. Start to distort. Good sound quality at medium to low volume though. nvx (aka sonic elecronix[yes they own nvx]) makes pretty good stuff.

Nice!!

The following review is for NSP46, which is a part of the bundle you are viewing.

very easy to install, good bit of sound out of such a small speaker. I put these in my front doors of my 2004 Chevy cavalier. I would definitely recommend these speakers!!

Perfect upgrade for 2001 Silverado

The following review is for NSP46, which is a part of the bundle you are viewing.

These 4×6 two way coaxial speakers are built with quality materials and sound great. They are a perfect fit in the B pillar.
