hey guys, as some of you know, i already have a 4 ch eclipse amp pushing a set of diamond comps complemented by an RF HE punch(old one). i just won on ebay a Xtant 301a mono amp http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 27444&rd=1 for ~$77. it puts out 300WRMS at 2 and 4ohm!

well, i was just wondering, now that i am using 2 amps, what do i need? dist block? another fuse?

in the manual description of the xtant amp, it says there is no onboard fuse. does that mean i need to put another inline fuse?

i am currently running 4GA power to the eclipse. i figure i can run that to a 2 output dist block and run 8GA to the amps?

lookin for some guidance. thanks guys

well if your cd player has 3 sets of pre outs you can use the rears... but otherwise buy a set of Y splitters.... and just wire the amp like you did the other... you can run a piece of wire for the remote from the new amp to the old amp too..

my HU doesnt have 3 preouts, only 2 :(

i have a set of knukonceptz 4 ch RCA's so if i wanted, i could use that, no? and just change 2 channels to the 2nd amp.

im also thinking of bi-amping(i think thats what you call it, where you use all 4 channels for the components) so in that case i would need another set of RCA's. in reference to the Y splitter, do i need any special kind for car audio? will it hurt my SQ?

in reference to the dist block, what do i need, since i most definitely will order from knukonceptz.

If you want to biamp the components you have 2 choices. You can purchase an external Crosover/EQ like the Audio control DQX that has 3 outputs. One for each high / mid / and low, or you can go the cheap route and use a Y spliter at your component amp and just use the front RCA out, leaving the rear RCA out for your sub amp.

You can get a Y spliter at any car audio shop, or even knukonceptz. Yes it will cut down on the siginal going to your amp, but it may not be noticiable to you. If it is you can always add in a active crossover / EQ at a later date, or a (can't think of what its called / little help KIKI)

As for the distro block. Something like this would work well.

so adding an active xover to the components wont do the trick?

If you install it before the amp, like the one of the audio controls then yes you could.

would the audiocontrol 4xs do the trick? i am unsure about this active xover stuff. just to make sure, i probably cant bi amp straight off of the amp without a crossover, correct? or could i put the tweets on the front channels, woofers on the rear channels, and use the amp crossovers like that? or would the freq's be too low on the front xover on the tweets?

When I say active crossover, I am talking about any crossover that is installed inline before the amp. Normally an active crossover has to have power conected.

A passive crossover is normally conected after the amp. A perfect example is the crossovers that come with most component sets.

Yes you could use the front and rear chanels on a 4 chanel amp, and use the amps crossovers. If the amps crossovers will alow you to run in the freq ranges required for the speakers you are conecting. In my stereo I have the mid crossed over at 80 herts, and the tweet at 2k. So if your amp will let you cross over the front and rear as HPFs, and alow you to adjust the crossovers to those freqs, then yes it should work for you.

Would the Audio Control 4xs work, it looks like it will, but I didn't read the whole manual. As I said above, if it will work in the freq ranges you need, then yes it will.

i just looked at the pic of my amp that i saved, the HPF only goes up to 200Hz.. thats WAY too low of a freq to send to the tweets. so i guess that means i need something like that audiocontrol? since this is the case, i most probably need an inline crossover before the amp, correct? is there any other way?
