Texas Tech Posted April 18, 2007 Report Share Posted April 18, 2007 (edited) Okay so i have purchased a mb quart component system taht is 4 ohms tweeter and woofer set....you know... Anyways my question is, i have an older, cheaper alpine Head Unit that has only one pre amp output and i believe it is for a subwoofer. I was wondering if I could run the RCAs to the amp that will be powering my component system... or do i need to buy a new head unit. If i need a new head unit i have seen some with specifications reading : front, Rear, and sub output. Does that basically mean 3 pairs of RCA outputs from the H/U? And can you only use the front and rear for for woofers and tweeters (basically component sets) and the subwoofer output for the amplifier that powers the sub. Also, I am going to have multiple amps, which means multiple REM wires. I have heard you can use a relay, can someone help me out here, i dont really know anything about this part. maybe a link to what i could buy for the REM relay or a solution...

Texas Tech Posted April 18, 2007 Author Report Share Posted April 18, 2007 alright, but i dont really want to buy one at this moment. maybe someone can answer about the sub output question Quote Baylor University Accounting Link to comment Share on other sites More sharing options...
kingsuv Posted April 18, 2007 Report Share Posted April 18, 2007 There's a couple of ways you can do it. 1. like Nismo said get an EQ. the deck you have now is most likely one that will hall full pass preouts. Which means you will get full range out to what ever amp you plug them into. You can use the preamp out for your comp set now. 2. Buy a new deck, look for one that will have 3 preouts. front and rear will be full range and the third will be sub range only. As far as relays, look into, http://www.bcae1.com/ one of the most helpful sites out there for startin out. Quote Designing, building, and shipping boxes.

I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...
Texas Tech Posted April 18, 2007 Author Report Share Posted April 18, 2007 thanks for the great response, thats pretty much what i really wanted to know, about the range of frequencies thorugh each pre amp output. I am going to buy a new H/U anyways probably in a week after i get two checks. Quote Baylor University Accounting Link to comment Share on other sites More sharing options...
Texas Tech Posted April 18, 2007 Author Report Share Posted April 18, 2007 dang so that is what that is, i didnt know what this thing was udner my dash for my alarm system but it was a relay. haha sweet Quote Baylor University Accounting Link to comment Share on other sites More sharing options...
roscoe1129 Posted April 18, 2007 Report Share Posted April 18, 2007 all righty then!!!!!!!!!!!!! j/k with a head unit that has 3 pre outs 1 set (front) tyoically runs ur driver passenger speaks, 2nd set (rear back seat, rear deck- back doors) sub....pretty self explanitory. now with the remote to turn on ur amps, u were good for 1 or 2, i have always ran a relay to help that process along just because i have seen ALOT of head units rem wire go bad due to running multiple amps. Using a 30 amp SPDT relay, connect terminal #87 to constant 12 volts positive , Connect terminal #85 to ground, terminal #86 to the remote turn on wire from the head unit, and terminal #30 to each accessory with an appropriate fuse. A fuse could also be used between the output of the relay (#30) and the remote turn on wire of the amplifiers and/or processors for extra precaution.

roscoe1129 Posted April 18, 2007 Report Share Posted April 18, 2007 just go to the autoparts store or stereo shop and tell em u want a relay and hook it up like I mentioned above. It just takes a few minutes and a little wire and female plug connectors.
