Crunch 2000.4 car amp, need help tuneing


re-check the speaker connections are correct and use a matching ohm test speaker on the other connections for a sound check. Sounds like hi frequency output into the sub amp. Sub-woofers are a mono signal!!

Looking for info on how to hook up sub to this amp thunder4160


Hi, you have two choices for hooking up a sub to the 4160 amp. You can either connect your sub to one of the two available channels, or if the amp supports it, you can bridge channels 3 and 4 to get increased power to your sub. You have a 4 channel amp - channel 1 and 2 go to your 3-way speakers up front, which leaves channel 3 and 4 available for your sub.

    I have 4/3/2 ch. alpine f-240 amp- i want to hook up four 6x8 3-way and one 12''sub. the amp has bass EQ on ch. 3. how would i hook it up and get the most power. can i put the 4 6x8 bridged all together...


    run two 6x8s on each of the front channels of the amp. then depending on the sub you can bridge it on the rear channels.only if its a single four ohm. if its a dual 2 ohm sub run each coil on each channel. 1 coil-1channel. the other coil-the other channel. amp should run fine may run a little hot since it will be doing all it can do at a safe ohm load. just make sure it is mounted in a well vented area. should be safe.

    Im trying to run two kenwood 6/9,s and a mtx sledge hammer 12'' sub of a mtx 6004 amp.where do i put my rca,s front or rear / and if this is poss how do i bridge the sub ????? im lost


    Im kind of confused with what exactly your asking. Are you trying to run 3 subs off of an amp? If so, the RCA's should go to the front of the amp, and if your plugging 3 subs in to it, you need to have a 3+ channel amp. There is a way to hook it up differently though. I have 4 12" Hifonics subs running off a 2400 watt Nitro-BMW-486 amp. I just have two subs running to each of the two channels.

    PXA-H700 optimum set up...


    The way the EQ is hooked up is correct.

    You set the factory radio to a set level, then use the volume on the EQ for everyday adjustments.

    I believe your problem lies in the amplification.
    Your BOSE amplifier was made to run a 4 channel 8ohm stero load.
    Low powered - high in sound quality.

    You have swapped the factory 8 ohm speakers (15W) for 4 ohm power hungry ones.
    Now the amplifier is working harder to produce the same output.

    You would be best served eliminating the factory amplifier and getting 1 good 4 or 5 channel amp to power your speakers.

    a 4 channel amplifier could be used stereo (left and right) on channels 1 and 2, (2ohm stereo load)
    and bridge channels 3 and 4 for your subwoofer.

    For a true surround sound - a 5 channel amplifier could run each speaker individually, and the 5th channel is reserved for the subwoofer.

    a small dedicated 75wx4 channel amplifier with built in crossover, and level gain controls - would blow your socks off. It is 200x better than the factory 12Watt amplifier. Your ears will love you for it :D

    If you need more help - just let me know.

    How do i bridge 3 subs to a 4 channel amp


    My information shows the XM-1652Z as being a 2-channel amp. It will not be stable below 4-ohms in bridged mode. For best power, your subs will need to be 2-ohms with all 3 wired in series. This will present a 6-ohm load to the amp. After wiring the subs in series, connect the positive speaker wire to one channel (+) and the negative speaker wire to the other channel (-). For the 1652Z no other wiring is necessary. For subs you will also want to set the LPF (80Hz) switch to the "ON" position (to the right).

    Keep in mind that the rated output is only 400 watts RMS at 4-ohms in bridged mode. That's kinda wimpy for 3 subs. You would probably obtain better results from two 2-ohm subs, each connected to a separate channel. That way each sub would be getting 200 watts RMS, still low but there's lots of good subs that will sound pretty loud with 150-200 watts

    Bidging


    You can't bridge 4 channels into one channel. You can bridge the amp to two channels and drive one dual voice coil speaker.

    Cerwin vega ht-10d subwoofer won't work in yamaha reciever


    Well, as I know, your Cerwin Vega subwoofer is designed for use with stereo systems. Therefore, it has only 2 channels for input, and 2 channels for output as well. However, you can try this out; the first thing I suggest is that you hook up your main front channels through the subwoofer. All you have to do is to connect the subwoofer input to the front channel output on the amp, then hook up your front speakers to the satellite output on the subwoofer. As long as you make sure that system is working on 8 ohms, I believe this can activate the subwoofer.
