## 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.
