Review: The best $20 pair of speakers you can buy - These are not audiophile quality speakers. The magnets are small, the bass isn’t great, and the highs aren’t super crisp. What they are, are $20 a pair speakers. Let’s be honest. If you are expecting these to sound like expensive speakers and keep up with your big amp, the quality of these speakers is not your biggest problem. However, if you have an older car with a stock stereo, or even a midrange aftermarket deck that’s still trying to push the crappy stock paper speakers, these will be a definite improvement. I bought two pairs of these and a couple pairs of adaptors to fit them in the doors and behind the seat of my 1996 Ford truck. I have a midrange Kenwood deck that was playing through stock paper 6X8s behind the seat and even worse than stock 5.25” “Roadmaster” brand speakers someone installed in the doors many years ago, before my ownership of the truck. The improvement these speakers provided was nothing short of miraculous. They don’t compete with the premium systems in my or my wife’s modern vehicles, but for $20 a pair, they’re damn good. I’ve rated these speakers based on what you get for your money. For just $20, you get a pair of speakers that let you listen to your stereo at a respectable volume, without distortion or crackling. What more could you want for that amount?
Review: Bof - Bien pour le prix, mais il ne faut pas s'attendre à des miracles, manque cruellement de basse. Après je n'ai pas d'ampli, pet être que le son serait de meilleur qualité.

## Questions & Answers

**Q: is it 30 watts rms each ? or 15 rms each to make it 30 rms?**
A: Pretty sure it's 30 each. Still not very high...These would be best suited to to run off a factory unit, or lower powered aftermarket head unit or small amp....It's not as much about the max watts so much as the rms, match that up to your amp whether it's the HU or external amp for best efficiency...

**Q: What size amp should i use if i buy 4 of these?**
A: U can use a 400 what's. With low frequency

**Q: do you need a wiring harness or any connector?**
A: Mine were direct replacements, the head unit i had bought 3 weeks earlier came with a new conversion harness, I did have to change the connectors on the speaker wires.

**Q: do these have to be broken in? My stock speaker is louder than them**
A: I doubt they need much breaking in. I wouldn't play them too hard maybe at first but these are a budget speaker at best, don't think you're going to get real great performance out of them. Your stock speakers probably are louder at the same volume on the radio due to better mid range sensitivity ...most regular oem systems have pretty ho-hum speakers, but do produce decent volume for mid-range sounds.
