As far as comparing sound, depth and distortion, the previous owner had Polk db401 units in the dash, and the sound is comparable to my current Polk DB461 units, not as rich though, if that makes sense. Better mid range for my listening. I will try a set of Reference 5.25" Infinitis I have to compare just to see what sounds better for me. Solid installation and base, while cancelling out any vibrations in the dash is one of the things I can highly recommend. With the Sony XA AVX3000 unit I have the 55w x 4 output is pretty decent all considering
It does make sense, I get it, our ears know what they like. Last week I was thinking if it would sound better if I replaced my 5.25" speakers with 4" (not 4"x6") since the 6.5" woofer is on my head and I would rather the front dash audio be higher to mid. I don't need the 5.25" to play down so low, I would rather have better highs and I think a 4" could do that. This is also a jeep and I cannot stop tinkering.
