Review: Great Speakers for Arcade Machine Project... - These are Great Speakers.. Used in my Arcade Machine, These 300 Watt poly plastic speakers (4 ohm) are a great replacement for those cheap poor sounding paper speakers used in the 80's Rampage Arcade Cab. Did not use included speaker grills cause the Arcade already had one and they would not work well for that application, Probably use them on something else.. Hooked them up to an Auto car audio amp (4 ohm) for great sound from PC in Arcade Machine and Mame !! Really Great Sound's for 8 Bit Games. Sounds really Mid Range and Tweeters have great Treble... For Bass in my arcade will have to add a extra Power Subwoofer. Never connect 4 ohm speakers to 8 ohm stereo tried this and it almost killed my stereo, mate 4 ohm to 4 ohm and 8 ohm to 8 ohm. (4 ohm is used mostly in car audio and 8 ohm in home stereos, just for your info)
Review: High quality, low price !! - I have a little system in my jeep wrangler tj. The sound quality just wasn't there. So I decided to replace the speakers with some high quality BOSS. High quality, Low price. The perfect product for your system if your on a budget. I installed 5.25's with 1 inch tweeters on the front and 6.25's in the soundbar. BOOM, brought that system to life!!! The install wasn't easy. Jeeps aren't made for big sound systems. However I have been installing stereos for over 25 years and also been a factory authorized service technician for BOSS AUDIO. So I can make anything work. High quality speakers for a low price.

### ⭐⭐⭐⭐ Not the best quality but great for the price
*by M***N on May 5, 2020*

This product offered decent audio. There are many specific audio details to be made about this product but the price is what attracted me. If you are looking to buy this product you are not looking to buy a high que speaker. Nonetheless, I am happy with my purchase.
