    HELP Sony Car Speakers for Home Audio Problems

    Hello,
    I recently purchased some cheap high quality Sony car speakers off Ebay for home use with a decent amplifier. After connecting everything up and testing, I found the sound is terrible. The speakers are only 4" but there is liteally no audable bass even though the cone is seen to be moving well enough. They sound nothing like the bass and quality from a standard speaker in a car enclosure. I have tested with one speaker in a smallish enclosue and one in a large but they both sound the same.
    Is there any particular reason for this such as that car speakers are not meant to be driven in standard speaker cabinets by home amplifiers?

    Please Help.

    Thanks.

    are there any caps on the input that would cut ot the lower frequencies? are you sure your giving it a full range signal?

    There are no caps, I am powering it straight from a Sony Amp much like this one http://www.son-video.com/Rayons/Hifi...AFE370NR_L.jpg
    I have tried the amp on other small high quality drivers and they sound great, one even in the same size enclosure. The signal is therefore full range.

    They arent the best but I think they are quite good. You have to hear it to realise how little bass there is and how bad they sound, there is definitly something not right. These are them here. http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWN%3AIT&rd=1

    Im literally getting far better sound out of 3" PC speakers at the moment.

    are you using 2 of them out of phaze with each other maybe, & canceling each others bass out?

    Going with turbocad6's suggestion - even if it looks like you have polarity correct, I would still reverse the '+' and '-' on one of the speakers to see if it makes any difference.

    I had tried this earlier, I just tried it again and it's still not working I know there's nothing wrong with the amp, as I am only using it to test them. It has been powering 8" pioneer speakers fine in phaise for a long time. Interestingly enough chaning the polarity doesnt make it sound any different with two drivers fighting each other so something isnt right. Then maybe it's because the bass is so little I can't hear the difference anyway. One driver on it's own is still easily out performed by 2+half inch driver connected to the amp quickly in a same size cabinet. Would the fact the amp is not meant for 4ohm loads make any difference in terms of sound other than damaging the amp if I were to power the speakers of it permenantly?

    if the amp is looking for 8 ohm drivers, it will probably work harder at the 4 ohms... depends on the minimum specs of the amp weather it hurts it long term... but it should put out more power into the 4 ohm's than 8...

    it sounds like you've done enough testing to confirm that the problem is with the drivers themselves...
