    Subs....

    Okay, my headunit does not have ANY outputs except for front left, front right, rear left, rear right. All of which are amplified by the headunit at 40 watts.
    I want to buy an amp and one or two sub's the problem is.... How do I connect them to the car stereo?!?!?

    most amps have input suitable for connecting your amiplified speaker output to... as long as its within the amps signal input power you should be fine, just check up on it. Otherwise, if u want really good quality i suggest u get a better headunit with RCA outs.

    yeh u can do, check with the amp obviously, some dont have high inputs at all. but that would be fine with the right amp.

    You might want to think about buying a better head unit, get something with RCA outputs and use a proper amplifier for your speakers. You'll have better linearity and you'll be able to adjust more things.

    Else, make sure the amplifier you buy for your subs (as said before) has a high level input, plus look out for a subwoofer crossover (some sort of lowpass filter). You don't want to be sending higher frequency components of the sound to subwoofer, it'll sound horrible.

    Hey man,
    Dont connect the HU's amplified output to any amps input... thats just asking for trouble.

    Go to Best Buy, or Circuit City and look for a line-level converter. You will be able to splice this into your rear channels and lower the output voltage/ level to safely connect this to an amp. Line level converters also give you a nice set of RCA outputs.

    If you can't get a HU that has a line-level output, then you need the converters.

    you can also get a crossover

    it takes the speaker ins (fl,fr,rl,rr) finds the low frequencies for the sub, provides outputs for the (fl,fr,rl,rr) and of course sub, and often provides a "master sub control" as well, you get diff types some that work on rcas others that work on speaker level, I got one and wow what a diff it makes having independent control over a potentially boomy sub

    Pretty sure that the high level inputs on an amp use a built in line level converter to lower the signal level.... My amp came with an adapter that has one end that plugs into the amp and unterminated wires on the other end so that you can splice directly into the car's existing speaker wiring.

    I'm using an Infinity Basslink:
    http://www.infinitysystems.com/carau...y.aspx?Ser=BSL

    It's simple to install as it will accept line level or speaker level inputs. I'm really happy with the amount of bass it produces for it's size. Best part is it's small enough to fit in the compartment behind my drivers seat and is completely hidden!
