I have a 2011 with the sony navigation and my factory front door speakers bottomed out so easy so i replaced them with polk audio db571s and they bottom out very easy as well. I dont want to replace the factory amp because I'm not too fond of cutting factory wires so he recommended the infinitys for my application, would handle the stock power better and make good sound. Does anyone have experience with these speakers?

Reference speakers are fairly decent, but they are the lower end infinity speakers... what you may want to do is use bass blockers to get the lower frequencies out of the door speakers. If you have the Sony system, then you have a sub, so you wouldn't be losing anything.

Bass blockers are cheap and you cam wire them into the crutchfield wiring harness instead of your factory wiring...

I don't know what the frequency range of the stock sub is, but 100-120hz tends to be a good level to block out of the door speakers.

This, exactly.

Ive done bass blockers, 200s, and when my lows hit my and it shuts down my lows and my highs quiet down as well

200hz is a little high. You should be pretty safe at 120 hz.

It still bottoms on certain songs..low low notes. The 120 would take out less right?

120hz is the frequency in which the blocking starts. Those low-lows are probably 60-70hz... a 120hz bass blocker will taper off sharply from about 125hz to about 110hz, anything 110hz and lower will not hit the speaker.

If the 200s you bought before were probably not bass blockers if they were taking out highs. Bass blockers won't reduce power, they just strip frequencies below whatever point out.... 200 is really high for a bass blocker also, it would eat into your mid-range tones and give you a frequency gap that will give you a hollow sounding system.

This is what I put in, they right? Except 200 hz of course
