l7 amp help???

Question

wut kicker amp would work best for the 15 in kicker l7?? its rated at 1000 watts rms and 2000 peak... its a 15" subwoofer with dual 4-ohm voice coils.. if i had 2 of these what amp could i run both off??? most of kickers big amps are one channel.. would i be able to run them of just one amp? help please!

Answer 1

yes you can use a mono amp for 2 subs. i think if you gave them 500 watts a piece they should be fine. but if you want to give them both 1000 watts, then you can, just be prepared to spend some money on a new alt, battey, and probably cap.

Answer 2

For two subs....

Wire the subs like so http://i81.photobucket.com/albums/j230/sparky3489/DUAL-PARALLEL.jpg

to this amp BXi 2006D 2000-Watt x 1 RMS @ 1-Ohm

Just be aware loading at lower impedances (1 ohm) can introduce a higher THD (total harmonic distortion) than higher impedances (4 ohm), the problem is finding an amp that's 2000 watts RMS @ 4 ohm.

However, the XX Goliath Mono-Block Ultra D-Class Design
5-kiloWatts/1 x 5000 -Watts RMS @ 1-Ohm

is 1800 watts RMS @ 4 ohm. For this you would wire the subs like so http://i81.photobucket.com/albums/j230/sparky3489/PARALLEL-SERIES.jpg

Either that or get two 1000 watt RMS @ 2 ohm amps and wire each sub to each amp like so http://i81.photobucket.com/albums/j230/sparky3489/SINGLE-PARALLEL.jpg using two BXi 1606D 1600-Watt x 1 RMS @ 1-Ohm

which is 1100 watts RMS @ 2 ohm each.

Something to consider.....This is an example...

To calculate the current draw of an amplifier, multiply the number of channels by the RMS watts per channel (a 2 channel amp rated at 500 watts RMS per channel would be 1000 watts). Double it to account for amplifier inefficiency (1000 watts X 2 = 2000 watts), then divide by the average output voltage of an alternator, 13.8 volts (2000 divided by 13.8 = 145 amps). Since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (145 amps divided by 3 = 48 amps).

This is an average approximation of current draw and it can go higher. So I would gather between *48 and 72 amperes for this example.

The alternator of a:

compact car is about 35 amps
mid-sized car is about 65-75 amps
SUV is about 145 amps

Calculate 40% of the amperes of the alternator you have now. This is the average current the car uses when running. Add this number to the approximate average current draw (*48), and you will come up with the actual size of alternator you need.

If the number you come up with is the same as what your alternator supplies, you need to take no action.

Answer 3

if you got two of those, you'd be looking at either a 1 or 4 ohm load after wiring them up.
You could definitely run both of those off of one amp. I would suggest going the 1 ohm route, and since you have the L7's, why not go with a kicker amp?
