new subs, too much bass

I have a 2000 TransAm with the Monsoon stereo system. I had to replace the 2 6.5" subs that are in the sail panels. I decided to go aftermarket on the subs because i replaced them once before with original GM but they didn't last long. I installed Audiopipe 6.5" TS-V6 subs. The original subs are 4 ohm dual voice coil speakers. The Audiopipes are also 4 ohm dual voice coil speakers so i hooked them up the same way as the originals. The problem im having is i have to turn the bass way down on the EQ because on song that have alot of bass it sounds distorted but when i play a song with not that much bass it sounds like there is no bass at all. With the OEM speakers i had the EQ set and never had to adjust it. Is it possible the Audiopipes have a lower frequency range compared to the OEM's ? Is there a way to cut some of the bass without lowering the EQ way down ? I hope i'm explaining this right lol Thanks

are you positive you hooked the polarity up correctly?  What happens when you balance all the way to the left or right, does it sound better?Kevin Pierson

Buy an aftermarket amp for aftermarket subs. The factory speakers have a x-over frequency range for each speaker input. They are not technically subs per say. Basically you are sending the higher frequency to one voice coil and the lower frequency for the other. For monsoon i usually recommend doing a full amp bypass to negate this effect. To make it sound similar to what you had before, return the 6.5 sub. Get a single 10" DVC sub such as infinity and put it in the hatch area. For the speakers you will want 4 new speakers and either run them off an aftermarket stereo which will distort the sound at higher volumes b/c not enough juice, or get a 4 channel amp. Mount each amp under each seat. Or just get a 5 channel amp. That or you can get replacement speakers and save yourself some money. But aftermarket is cheaper to replace down the road. Either way get that sub off of the factory system ASAP! So you don't cause any more damage than you possibly have.

I suspect you have an impedance or a polarity issue.  The speaker is probably not hooked up correctly - even if you hooked it "exactly like" the OEM was connected you can't be certain since OEM system often use non-standard connections.. Support the12volt.com

Before i disconnected the speaker harness pigtail from the original speaker i verified polarity with a battery to the speaker. I didn't verify polarity with the new speakers because they were clearly marked red and black. When i balance all the way left or right it sounds the same.

I am 100% sure, its DVC. I already tried connecting one side only on the speaker but its too low.

Sounds like the speakers are moving to much, probably not as stiff as the factory.  You  might try reducing the airspace behind the speaker, rewiring speakers to series to reduce power, or trying a better speaker.(bigger coil, longer throw)

I spoke with someone tonight about this and he also said i should reduce the airspace behind the speaker with some filla foam. He also said the new speakers have a higher sensitivity rating compared to the factory ones, thats why its louder. He said to put a 6 or 8 ohm sandstone resistor in series with the positive lead to reduce it.
