  1. Hey guys I would be wiring up my 4 channel amp, and have a few questions. (1) I have read that the power wire should go one side of the car and speaker wire (rca) should go on the other side. Should the remote wire go on the side of the power wire or on the side with the speaker wire? (2) I am using 2 ch bridged for my sub, and the other 2 ch ( built in crossover on amp), for a pair of mids and tweeter. what frequency should I set it to? (3) The HU has 3 pairs of 4 volt rca pre output, should I use these or the the wires from the hu haness to feed the amp or a combination of both? , I have rear speakers which can also be included, what would be the best setup? Thanks.

    Would you guys be kind enough to recommend a pair of good tweeters... info. Budget- $200 - $250 for the pair Would be connected to a single channel with 160W rms in parellel, 2 ohm load (active). (sax 100.4D) Prefered, (but not limited to), to buy tweeter with x-over, hence gives me the option of going active or passive. Thanks.

    Stereo. Simple rule of thumb.....you need a "left" and a "right" for everything except the subwoofer. Midbass, midrange, treble (tweeters)....all stereo. You can still run the system from the single 4-channel amplifier.....it'll just require you use a passive crossover for the mids and tweeters instead of running active. I had a system like this a couple years ago and really loved the simplicity of it. Were you wanting a single amplifier for space reasons, simplicity reasons, or budget reasons? Yeah I will run the single 4 ch amp for now, and add as money comes in, thanks alot for all your help..

    Do NOT do this. Your music is stereo. You must maintain independent left and right channels for the speakers in order to maintain stereo sound. Your proposed plan would not separate left and right signals, the results would be disastrous.....an aural abomination. The left speakers must only receive left channel information, the right speakers only right channel information. You have three main options; Run the front speakers (mids and tweeters) with passive crossovers, with the left mid and tweeter on channel 1 through a passive crossover and the right mid and tweeter on channel 2 through a passive crossover. Add a smaller 2-channel amplifier to the system to run the tweeters and try to run the system actively. Then you could have one tweeter on each channel of the 2-channel amplifier (left TW on CH1, right TW on CH2) and use two of the channels on the 4-channel amp for the mids (left Mid on CH1 and right Mid on CH2; CH3/4 bridged to the sub). Add a dedicted subwoofer to the system and run both the mids and tweeters from the 4-channel amplifier actively (left TW on CH1, right TW on CH2, left mid on CH3, right mid on CH4; subwoofer on the mono amp). Honestly, given your experience level.....active sounds like an extremely bad plan for you. Your best option would be to go with a passive component set. In other words, don't look for mids and tweeters separately.....look at one of the many predesigned component sets from the main manufacturers. Really, we need to start from scratch. What is your budget? Axis basically refers to the speakers aiming in relation to your listening position (the drivers seat). If the speakers are aimed towards you, that's on-axis. If they're not aimed towards you, the are off-axis. My initial plan was to use the sax 100.4D for a total system amp, front stage (tweeters & mids) & sub, in an active setup. And later add a dedicated sub amp, and use the ch 3/4 on sax 100.4D for mid bass drivers. However I can clearly see thats not possible. Thanks for your insightful response, I would have to go back to the drawing board and figure out which way I would go, looks like I would have to start passive and later on go active, with a dedicated sub amp, and also include a third amp (2 ch) for mid bass. One remaining question I have, would mid bass be mono or stereo? thanks for all the responses....

    Why are you connecting the tweeters in parallel to a single channel? Additionally, it's impossible to give recommendations for tweeters without knowing what your implementation is. What mids will you be using? How low do you need the tweeters to play? Can you fit large format or small format only? Will the tweeters be on-axis or off-axis? Do you have a preference in sound? And, again, why are you connecting the pair of tweeters to a single channel? will try to answer some of your question, as I am fairly new to this.... I am using a sax 100.4D ..ch 1 tweeters, ch 2 mids, ch 3/4 bridged for sub or mid bass depending if I extend the system by adding a dedicated sub amp later.. Using tweeters in parellel to maximise power from a single ch which would be 160 watts at 2 ohm load instead of 100 watts at 4 ohms. Will be using a pair (unknown as yet) of 6.5 mids 4 ohms in parallel, again to acheive 160 w instead of 100w, could do with that recommendation aswell....?? I can fit large or small format, do not know what you mean by on or off axis??, with respect to sound I am heading towards SQ as a total system. (also according to specs the amp is stable at 2 ohm stereo, and 4 ohm bridged)

    fi Q 12 ported

    Hi guys, I was looking at the cut sheets for the fi Q 12 ported which is tunes to 32 Hz, and have a few question. what would I have to do, (if it can be done) to the same box, to tune it to 28 Hz? Or Would I have to build another box? Would you recommend tuning it to 28 Hz as opposed to 32 Hz ? What are the prows and cons? Thanks, Shopvac

    fi Q 12 ported

    No goals specifically, been reading on other forums, with all sorts of suggestions, just would like to build the right enclosure. Sorry for not giving much details, the box is for daily use. Big thanks to everyone for their attentive reply. shopvac

    SAZ 1000D or SAX 1200D ?

    Hi guys need your help here, would you recommend the SAZ 1000D or SAX 1200D to drive 1 Fi Q 12 Dual 2 ohms (1000 watts RMS) in a ported enclosure? I been doing some reading which indicated that, it's been recommended that the amp should be higher than woofer's RMS so I decided to ask the experts. Thanks, Shopvac.
