I understand they increase the signal voltage but with gain controls on amps why? Im asking because on my stereo I have an alpine H/U with 4v pre outs and and alpine pdx m12 & f6 amps. The speaker amp is fine but the sub amp has a switch to change between 0-1v & 1-10v inputs and with it on 0-1v input it gets loud buts sounds sloppy and with it on the 1-10v input it sounds great but needs the gain set really high (above 3/4) as well as subs turned up fully on H/U and full bass boost on amp knob thingy-ma-bob (the remote mounted bass boost controller).would a line driver make it safer to get the volume from the subs I'm after without clipping?Or would it just make it start clipping at lower gain setting?How do I tell if it is clipping and what is a good method of setting gains on sub amps?Cheers Chris Link to comment https://www.fordxr6turbo.com/forum/topic/79822-whats-the-benefit-of-line-drivers/ Share on other sites More sharing options...

Also more voltage means more clarity My line driver is also a equilizer which I mounted directly under the headunit. It has about a 9-10v preamp output voltage which is pretty decent. I've heard of 12 and 14 volt ones but that is serious money serious competition stuff.

It will be almost neglectable. If you want more frequency response your unfortunately going to have to get a better sub. I suggest tuning your amps so they don't try and go beyond what there voice coils are designed to. Last thing you want is a giant 12inch paperweight.

Firsty are your boxes ported? Link to comment https://www.fordxr6turbo.com/forum/topic/79822-whats-the-benefit-of-line-drivers/#findComment-1225870 Share on other sites More sharing options...

I just set the filter at about 80hz and turn gain to a point where im confident its safe. Not turning it up too high is the main concern as the speakers love the power they're getting at the moment and I reckon they'll last forever how they're set. I just reckon I should be able to get the volume im getting without turning everything up to its limits, the amp puts out 1365wrms to 2 alpine type r subs which have a power rating of 500wrms each Link to comment https://www.fordxr6turbo.com/forum/topic/79822-whats-the-benefit-of-line-drivers/#findComment-1225879 Share on other sites More sharing options...
MX Dave Donating Members 545 Member For: 14y 1m 24d Gender: Male Posted 22/04/12 04:19 AM Share Posted 22/04/12 04:19 AM Yeah sounds like you got it set fairly good. Seeing as there getting lots of power I'd personally run input voltage to half. Set it o low pass filter. Set low level frequency to 32hz to suit the box then change your high level frequencies to suit your taste in bass. Ie:80hz if you prefere deep bass or 150-200hz if you like the higher stuff too. But don't exceed what the coils can produce, I learnt that the hard way.. Ohh another 50 hz shouldn't hurt.

Is it worth going with a 6ch or is a 2ch "bass driver" better off ie: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=200550503500#ht_3157wt_1037 Link to comment https://www.fordxr6turbo.com/forum/topic/79822-whats-the-benefit-of-line-drivers/#findComment-1225908 Share on other sites More sharing options...
MX Dave Donating Members 545 Member For: 14y 1m 24d Gender: Male Posted 22/04/12 05:51 AM Share Posted 22/04/12 05:51 AM Have a look at Earthquakes line drivers, they also double as a equilizer (more bass with no extra risk) and are extremely good value for money.Heres how I set mine up Excuse the gearstick and blurryness its the only photo I have.
