Reply With Quotewhat mode are you running the sound in
2.0?
2.1, 5.1 or 7.1?
eg is the pc sending the bass to the main outputs or to the sub out
My setup:
Computer, Auzentech X-Plosion 7.1 sound card.
Alpine PDX-4.150 amp hooked up to 6.5" Focal Polykevlar components
Phoenix Gold amp (forgot model) hooked up to an 11" Focal Polykevlar sub.
I'm going straight from the audio card to the amps and the amps to the speakers.
My issue is that I can't get any bass unless I check the "bass boost" option in the sound card properties and the components sound like they're missing oomph. When I had the components hooked up in my old car they damn near shook the doors off the hinges by themselves. Is this a product of low voltage coming from the sound card and what's the easiest way to solve this? I'm not opposed to adding a DSP if that will fix it just as long as I can control it from my touchscreen. I'm also not keen on spending money on a DSP if it won't make a huge audible difference to my noob ears. What's causing this and what can I get to solve it? Products suggestions welcomed. Thanks guys.

Sorry for the noob questions but I'm still new and confused to car audio and its hard to diagnose problems when i dont have a very clear understanding of how these things work.
I have it running in 5.1 mode with the sub running off of the sub/center channel to a dedicated amp. There is a splitter coming off the sound card with the left channel hooked up to the sub's amp and the center channel simply turned off. The components show similar dead characteristics and I'm sure if the tweeters weren't hooked up their woofers wouldn't have much sound either which makes me think the sound card somehow doesn't have enough juice.
Also, do speakers have a burn in time like high end headphones do? Is it safe to run the speakers like this for a week or two until I get this figured out?
speakers often need a warm up period, but you should hear something ok initially, and it should just get better from there...
so with your speakers..to double check what you are doing.
you have just front component speakers?
or do you have 4 speakers running off that amp? front and back components.
guessing the outputs of the amp (for the components) splits via a passive x-over then goes to the tweeter and the woofer for each corner of the car?
one problem with running in 5.1 mode, is depending on how the pc sets it up, it may be putting alot of the audio out the front centre channel, and if you dont have that plugged into a centre speaker, well you wont hear it. and are you sure that the L channel of the centre/sub output is the sub feed?
you might be better to set it up in 2.1 mode and split that to feed the front and rear outputs and just set the gains on the amp to get the front/rear balance correct.
if your sound card has a surround mode, that MAY be a 4.1 setup, but again every setup is different and it might fake the rear audio and mess with it and put reverb and stuff on it.
additionally if its true 5.1 you wont hear anything from the rear speakers at all unless what you are listening to is encoded as 5.1, again depending on how the sound card sets things up, what you get from the rear may be not what you expect.
hope that didnt confuse you more
Exactly what Woofnstuff said.
SuperJ, I also have an Auzentech card, and they unfortunately use Creative drivers. I love my card, but it has the unfortunate downside that all Creative cards seem to show in cars in that the Center/sub jack has a very low output.
As much as I hated having to do this, I had to run a splitter out of the Front jack, with one side going to my front speakers and the other to the sub. This was the only way to get a good strong signal to the sub. Of course in this scenario you would turn OFF any bass redirection in the audio software.
I don't like splitting signals, but this scenario has definitely given me a great sound.
I have 4 speakers running off the amp, both front and back. The rear speakers are practically turned off though, I know they ruin the sound stage but I like a faint whisper of sound in the back.Originally Posted by Woofnstuff
I split the front signal out to the sub and it fixed the low volume problem. I wish a sound card company would support 4.1 rather than needing to split the audio.
I use the passive crossovers that came with the speakers.guessing the outputs of the amp (for the components) splits via a passive x-over then goes to the tweeter and the woofer for each corner of the car?
Unfortunately I still have a huge hole in the mids. There is absolutely no punch coming from my components. I checked the polarities and all of my wiring is good and the proper gauge. The doors are reinforced, sound deadened and sealed as best I could. The only thing I haven't done is solder the wire to the speakers, right now it's crimped on but I don't see that making that big of a difference. I'm still sorting the wiring out but I'll solder them on this weekend. I tried to set the gain according the the amp instructions using a 1K tone but I couldn't get it to distort but even with the gain not set it should have more kick.
