It's tough to get a good balance... Posted by IrieTom [Email] ![]() ![]() ![]() In Reply to: just finished installing 10" sub and additional amp..., kooch, Fri, 27 Jul 2001 01:55:25 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I'm running a pair of 8" Boston Acoustics subs in a sealed box (the box contains two seperate enclosures) and running them from a 30wRMS Rockford Fosgate amp. I had to turn the gain way down on the amp to achieve a nice clean sound.
The other speakers in the car are 4" mids in the dash w/tweeters just below the knee bolster and 5.5" 2-ways just above the rear seat side armrests. These are also B.A. speakers, and are driven by an a/d/s/ 50wRMSx4 amp.
The two amps seem to have different gain curves, so the amp is "boomy" at low volumes. I have to adjust the subwoofer output level to get the right equalization when I change the volume significantly.
As the others have said, a sealed box enclosure will give a more accurate sound than a ported "bandpass" enclosure. The positioning of the speaker can make a difference, as well. Try moving it around and listening for a while. You'll notice subtle changes in the overall sound.
And, last but not least, I recommend the under-the-back-seat amplifier, but be careful about ventilation. Some small 12V cooling fans from radio schlock can be a cheap insurance policy, and can be wired to run whenever the stereo is turned on.
