I picked up a  copy of "The Great Fantasy Adventure Album" (I
think it's put out by Telarc?), which has a LOT of very low-frequency
bass content.  When I encode it to AAC, even at a relatively high
bitrate, like 192 or 224 kbps, it seems like a good portion of the low

What would the major differences be between running two 250W rms 12" subs vs
one 400W rms 12" sub. I am talking about powering it with 300W rms. Which
one would give better SQ?
Also I suppose the 300W amp will drive one sub better that two, is this

How do I connect a dual 4 ohm voice coil sub to 2 channels? I want to bridge
the 2 channels but I can't put the coils in parallel because the amp is only
2 ohm stable. Can I connect each of the coils to a channel?
It is rated 100W per channel or 300W bridged.

    I don't have any first-hand experience with "class D" digital
amplifiers, but I saw an ad for a PowerAcoustik model that supposedly
puts out 2300W RMS into one ohm, and costs just a little over $300.
Even if they're wildly inflating the power numbers, that still sounds

Is it possible to bridge the speaker outputs to drive two speakers
instead of 4? If so, which are the connections that should be used?

My sub amplifier can provide power at 2 ohm stereo.  I have 2 12" 900w
max 4ohm subs.  Currently I have them running at 4ohms.  I decided to
try them at 2 ohms from the amp (which is 420w RMS x2)  I was very
happy with the result.  Not sure if they were any louder but the lower

Looking for opinions on which areas to cover for noise reduction in
the cabin of a SUV.  The goal is to increase the pick-up of the
microphone on my handsfree kit.  So I'm not looking to cover the
entire cabin with dampening material.   Please rank areas in

Just purchased a 12 inch JLW3 v2 sub and have available 150wrms bridged
output.
The manufacturer's recommendation for box size is 1.25cubic ft and sub is
rated at 300wrms.

I installed a 10" sub w/box and a 300 watt bridged amp last night in my car.
I'm having problems with the amplifier cutting out and going into overload
protection. It does this for 2 or 3 seconds, then kicks in again. The louder
I turn up the volume, the worse it gets.

DR Crankenstein car audio any good and where can I but DR Crankenstein online.
Is DR Crankenstein better than Rockford Fosgate high end.  

When running a DC transformer  to test car audio at 12V is it different to
what comes out of the battery, I have a 12V power supply at 1 Amp. Would it
be possible to use this to run an amp and sub?
Thankyou

Assuming my amp supplies 300 watts RMS, and I put each sub in the size
enclosure recommended:
What do you guys think about the differences between the Pioneer
TS-W304C or the TS-W305C. I have the 304 now, and it sounds good, but

I have 2 midbass up front with image dynamics compression drivers for my
front soundstage.  In the rear quarter panels I have a second pair of
midbass, playing from 65-350Hz.  Sub plays mono 20-65 Hz
Question... do the rear 1/4 panel speakers need to be playing in stereo,

I'm looking at upgrading the stereo in my 2000 Jeep Wrangler and stopped by a
shop today and asked a couple of questions. I was told that a 4x6" oval speaker
will not sound any different than a 5.25" round speaker. Is this true or is the
guy just trying to blow smoke up my a$$? ...
