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

metra 72-4568

The following review is for 72-4568, which is a part of the bundle you are viewing.

I have used these in a lot of different cars over the last few month's, just makes life A LOT easier. No more hacking up stock speaker harnesses just plug in and you're good to go. I would highly recommend these to anyone, and for the price you can't go wrong.

97 Grand Prix

The following review is for 72-4568, which is a part of the bundle you are viewing.

These were exactly what I needed to use with my 97 Grand Prix. Simple to use and very convenient. Does what they are made for.

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.

Excellent Accessory

The following review is for 72-4568, which is a part of the bundle you are viewing.

Perfect accessory to allow "plug-and-play" installation of aftermarket speakers directly into factory harness. Clean installation, no fuss. I have purchased from Sonic Electronix before and I have always received good product at great prices with fast shipping. Thanks again.
