    Nobody has mentioned this yet:

    Plug it into your guitar, it has a line-level out... Put that into some AUX-In or similar. Voila.

    Actually, any guitar headphone amp would do this.

    Apart from the obvious things like bass amplifiers being tuned for low frequencies, and all the other impracticalities, the fact remains that bass and guitar amplifiers are MONO. Some of them may have stereo inputs, but as far as I know basically all of them will only put out a mono signal.

    So you will be feeding your stereo speakers a nice low frequency, mono signal.

    I found this thread and am rebumping it as the idea is not so crazy after all. If sticking guitar amps in car was popular in the 70's this is no bad thing. Some disco tracks from the 70's sound better for bass and crispness than many 90's dance tracks. They really knew a thing or two about sound back then.

    Today I installed a maine 100 watt guitar combo which has two 12" celestions running of a maplin 150watt inverter fed by an iclix river mp3 player.
    I had already gone to a lot of trouble to make sure this mp3 player produced sub bass. I tried all the leading mp3 players from a specialist, only this one could reproduce sub bass with a degree of warmth and with the least resonance.

    The maine amp is a very heavy box, you need to be strong to get it in the car. The box solidity helps the sound to to kick hard. Tested it with heavy techno...Vogel, Cox also good classic disco, and some deep house. The amp is very good tight for bass lines. It kicks and is crisp with good high frequency distortions..very like a club system.

    I would recommend this for several reasons.

    It appears to be efficient for 100 watts and kicks at midrange like an 800 watt car system..can anybody explain how this can be ?

    The maine combo amp is rated as very clear amplifier that musicians rate, this will be because it produces pleasing distortions. Although there is no actual guitar distortion itself on this amp. The speakers themselves distort.

    So to sum up, this amp is giving a club type crisp hard kicking sound in a car, which i would be hard pressed to emulate without a major installation and restructuring of the car itself. If i change cars i just take out the amp. The speaker is fed from the head unit line outs.

    Drawbacks. Nothing much below 100hz is going on. I am thinking about replacing one of the celestions with a 12" 2-300 watt car audio sub. I know that this sounds like a mismatch of power. My experience is that studio equipment is extremely conservative in its ratings. For example my portable studio I installed one genelec 120 watt active studio monitor in my camper, and that sounds like about 400 watts of equivalent car audio..

    Even if the sub does not work, i cannot see how to get this mid range club sound without a major installation, which i am not keen to do as i may be selling the car itself.

    so yeh guitar amps, in a car.. not such a crazy idea after all.

    i had totally forgoten about this post.

    cool thing it worked out for ya. i had put my project aside for a while, but after your post can wait to resume it.

    the distotion you menction might be due to a pre amp circuit (so it the gain boost that geves your the "distorted" sound..)

    greetings.

    I have the pre-amp turned low, but tune the tone with a EQ guitar pedal. I think its the celestion cones themselves (GTA 80 classic lead) that seem to allow for some pleasing overdrive

    As an update, i replaced one of the celestions with a 12" Fli so called 800watt subwoofer, (retail 25) and now the system has some real low but tight and fast bass. Amazing deal, halfords are selling them for 25. I'm going to fit a skytronic PA crossover or bass filter (retail 10) as the celestion cone cannot handle the sub bass frequencies, which i'm boosting with another bit of guitar gear, a boss GE-7 guitar equalizer. So its Mp3 player into guitar pedal into amp. Behringer guitar and bass versions can be picked up on ebay for 30.

    Amazingly this is all running off a maplin 150 watt inverter, yet is loud enough to shake the van and my back seat while producing high frequency overtones that tickle the ears. I have serious doubts that a lot of this 800 watt modern car audio gear is louder than older 160 watt guitar amps. Back then they had regulations for what they could say their power ratings were. These regulations were lifted in the 80's or 90's, so they can say whatever peak figure they want.

    I have a Line6 PodStudio GX in my home studio that's entirely USB powered, and would work perfectly in a CarPC -- depending on where you put it, it even has a single-knob for master volume. Plus, the included software is leagues better sounding than running straight into your aux ins.

    A lot has happened since this last post. I went totally alpine regular car audio...

    I also learned why the 120 watt PA was so loud.. PA speakers are so sensitive they produce the same volume with just a quarter or even just a 16th of the watts into them of most car speakers.

    The disadvantage is if you dont set them up right they will blow more easily.

    We took our PA and wired it up to the car amplifiers in the back of the Van.. Massively loud compared to regular car audio speakers

    I figured you had a solution already, considering it was almost 2 years since you posted, but I wanted to throw out a viable solution for anyone who may still be looking.

    All things considered, ASIO drivers and slightly-better-than-stock D/A converters may sell me on using the GX in my own build, and having the 1/4" jack for roadside jamming would be a nice addition. But, you're right -- the setup you went with is a lot better for loudness, and if that's what you wanted, you probably went the right direction.

    Even Dog can't resurrect this one....

    But as to using high Ohmic music speakers and amps with the PSU nearer the alternator & battery....
