Bests & Worsts Reviews from Amazon

Excellent treble and mid-range, very efficient with high sensitivity to get good volume out of your watts. They are 3 Ohm, so even with cheap thin factory wiring it will help pull the power it should from your factory deck by settling at a final load about 4 Ohm. Other performance speakers may come from 3.3-4 Ohm despite all being labelled as 4 Ohm, you really won't know on any specific model unless you look up the spec sheet online, If you run an amplifier, it really shouldn't matter but with these being clearly 3.0 Ohm, they help pull the full amount of power available from your non-amplified head units, but also work well with an amp with it's good RMS handling level. Note: There will be little Bass at first, they take a month / 25+ hours of use to break in and loosen up and then the bass will come. This is especially true of stock power head units. You can speed up the process a bit by playing as much bass heavy stuff you can just don't push them to the point of distortion. Mine are finally hitting nice and deep after about 5 weeks with a low-power factory head unit, amplified they will probably break in faster. Adding months later now: yep, these definitely take a LONG time to break in using only deck power, after five 5-6 months I'm FINALLY seeing the bass I've been expecting. This is probably true with any speaker that can accept high power, they are built tighter to handle that high power so it will take a while using only deck power.
