Hi all,
New to the DIYMA way of car audio, and in my own setup which I'll describe:
2004 PT cruiser.
Older Pioneer CD deck (line-outs) model escapes me, its a consumer unit.
Old Audiocontrol EQX (original design - only 2 way xover and 13 band EQ)
Nakamichi PA-200 (35Wx2) driving Boston Acoustics S35's in the dash.
Clarion (60Wx2) driving Boston Acoustics SX65's in the stock door location.
Profile 200W driving a 10w3V3 in a 1.2cuft sealed box in the hatch.
I should mention both the door and dash speakers are on the "high" side of the audiocontrol's 90hz crossover point. The sub is on the low side. Also as 90hz is too low for the S35's I've added a high pass cap (it is meant to work at 4 ohms at about 700hz if I recall, It's a very good quality cap too - I wanna say Kimbercap but thats not right, forgive me I might be able to find its value and the brand if I need to.)
Also I have another passive filter on the output of the amp, another good quality cap and a coil meant to act at 150hz 12db slope. I realize this gives me a midbass hole, but thats for tomorrow to fix - my door speakers muddy up if I give em any lower than tha.
****** I get a very annoying "ringing" or harmonic, or some peak that is not in the source material. It happens with high pitched male singers and most female singers, or guitar solo's on the high end. It is very prevalent when the source gets very complicated with a lot of instruments. It only seems to happen at high volume. Its difficult to localize the source it seems to come from everywhere. I would almost say its sorta like low bitrate MP3 sound, but my source is uncompressed (several original CD's)
