I have a 2000 Ford focus and I want to add some subs, so i bought the Line Level Converter (Scosche SLC4) I know idid the "right connections" From running my power cable from the battery, and my remote cable which i connected to the radio Fuse, and I did ground the Converter...so everything looked good and works good....but I'mnot getting enough bass from my subs....is more like a regular speakers hook up to an amp!!! with a little bass but not the right response from my subs... Has anyone done this kind of connection as far is addingsubs with a line level converter??? cansomeone give me a hint on what might be done wrong??

There could many reasons. First check for the wiring of the sub, make sure they are properly wired. If the polarity of the speakers aren't all the same, the speakers will be out of phase sounding with poor quality. Check the line converter, most of them have a output gain regulator. If that's the case set it to maximum. Also check for the gain of the amp connected to the subs, make sure the frequencies of the subs are set to low. If you have a crossover check its gain.

A line-out converter will always give you the same frequency range of the speaker wire you connect it to, so it's not surprising that you're getting full range sound from the subs. You need to use the amplifier's built in crossover to cut out the high frequencies. Look for a LPF or low-pass setting.
Don't ground the line-out converter; for most vehicles it's not required (unless you have an active type that has a 12v power connection too).
You may have wired the LOC out of polarity, as mentioned above; to test this, disconnect one of the two speaker connections at the LOC and see if the bass level increases. If you don't get more bass with only one speaker connection at the LOC, then the polarity is probably okay.

It could be exactly as you suspect, that the line out converter is giving you speaker level output. If this is the case (try connecting a speaker to it and see what you get...) get an old cross-over

when you connect the line level convertor you made a mistake on one speaker and the cables are backwards , out of phase ,wrong polarity
just swithc the cables
god luck

your not gonna get it perfect with a converter. it will always sound better on an aftermarket head unit with outputs. whats the rms of the subs and the rms of the amp?
