You can't run TWO subs on the bridge!!!!! You will destroy the amp! Put ONE sub on EACH channel.

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.

How do i hook them up to work for 2ohm's

Hello rcantu76,

If your CVR's are 2ohm (model Nr. 07CVR122), you connect the voice coils in series and then parallel both subs to the amp. If the subs are 4ohm (model Nr. 07CVR122), they cannot be wired to 2ohms. Your choices are 1ohm or 4ohms. According to Rockford-Fosgate's data on the P1000-1bd, it is stable at 1ohm.

To wire the 122's at 2ohms, you would connect the sub voice coils in series (jumper one positive to the other negative on each sub), and then connect the remaining positives and negatives to the amp.

To wire the 124's at 1ohm, you would connect all of the positives and all of the negatives together to the amp.

Hope this helps.

Using JBL 4410 3-Way crossover, trying to use PG 12" Dual 4-ohm

ok, connect the amp positive to the positive end of one sub coil, take the negative of that coil, and run it to the positive of the second sub coil, then run the negative out of the second sub coil to the negative of the amp.

Have you checked to see if your subs voice coils have shorted. That could cause the amp to heat up, on rare occasions the protection lights don't work. Rare, but possible.

Hooking up DVC subs

The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.

Compatible amp for subs

hi there. yes it should work providing you have the correct wiring it for it, if you buy the LV 416 enquire about a wiring kit to fit, most will. theyre normally around 20pounds. most amps will be compatible with most subs. i run both my 12inch 1000w off one 1200amp at half power, they kick lovely and i have no problems.

any other quiries please ask
