And only depending on which notes they hit. most the time its ok at regular listening levels.
I have an 03' Sedan. I really need to change out the HU, but the cost is pissing me off.
I have a question for any one that has at least 500W RMS of amps in there ride. Do you lose any power when your bass is up a lot? Meaning from the car itself. Such as hitting the gas, and feeling any jerkiness to the flow? At normal 50+ MPH speeds I don't notice it. only at low city speeds does it seem to be there. I have a total of about 1400W RMS in Amps. I have a 3 Farad cap (which should be sufficient for 3,000 Watts peak). I noticed that at heavy hits, the voltage goes do the low 12v and can go to 11.8v at worst. Normal voltage reads about 14.2-14.5v. I don't know if that is a lot. Maybe a bigger battery, or alternator? Or is even a bigger cap in order?

If you want more bass, have CC tap into the signal before the amp again and get a line amplifier to increase the voltage to the amps. Since it sounds like you have more than one amp, a line driver would really benefit you. The Bose EQing is bad news for good sound.
What kind and how many amps do you have? Do they accept a balanced input signal? If not, that may be part of the problem.
