Great Product

The following review is for 72-7401, which is a part of the bundle you are viewing.

If you wish to replace you’re factory speaker with something higher quality quickly and easily without cutting the factory wiring connections this is perfect. No cutting or splicing just plug and play. Can easily put factory speakers back if needed. Suitable for smaller amplifier but wouldn’t run anything high power. Very easy to install. I used them in all 4 doors on a Nissan Versa

Perfect for brokies like me

The following review is for Stage1621, which is a part of the bundle you are viewing.

Got quality speakers for my 13yo Kia, old speakers rotted away due to being made of paper. These new speakers A: sound better (duh), B: won’t rot away, C: was just under $60 for two speakers, adapters that needed slight modification, and the wiring harness. Best $56 I ever spent
