Review: アルトワークスのリアドアに設置。 取り付けに際し、別途16cmスピーカー用のインナーバッフルとインナーバッフル取付用のボルトとナットが必要になります。 サウンドは柔らかく、サラウンドスピーカーとして最適です。
Review: 十年以上前に買ったビクターのスピーカーコンポの、音が気に入っていました。ただ、経年変化は避けられずコーンエッジが硬質化して、不用意に触れたところが凹んだりしてきました。ハイグレードのものと買い替えるほど費用がかけられないので取り付け互換性があり、まあまあ信頼がおけるユニットを探して購入しました。元のコンポは２ＷＡＹですが、 これは１台でフルレンジです。大音量で聴くことは無いので能力の限界はわかりませんが、十分満足しています。コストっパフォーマンスは最高です。

## 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.

配送が最悪。ビニール袋に入れただけで配送されてるので、箱が破れてたりへこんでたり。 幸い箱だけでスピーカーは傷んでなかったので、交換するにしても時間かかるので、返品はしなかった。 急いでないモノだったら当然返品、交換。 箱に箱という考えはないんだろうな。買う人は注意。
