Question about Sony XM-1252GTR Car Audio Amplifier
What i would like to know is the sony amp good to power the kicker L7
the sony amp puts out 550 rms at 4ohms and 900 rms at 2ohms the
amp is 2ohm stable .the L7 is a 4ohm dual voice coil when wired in parallel it goes down to 2ohms and when wired in series it goes up to
8ohm load right now i have it wired in series at 8ohms powered by a
sony xm-1252gtr 2 channel amp bridged in mono the amp puts out
340 watts in bridged mode the amp is also 4omh stable in when bridged
in mono its sounds good the sub is in a 1.30 cubic feet enclosure in regular cab truck just want to know if any of these two amps are ok for the L7
The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.
You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.
Hope this helps.

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil. To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series. This adds the ohms, so that you either have 4 or 8 ohms.
I am using the following codes to show wiring. VC1+ stands for the Kicker Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.
AO+ to VC1+
VC1- to VC2+
VC2- to AO-
This shopuld give you 4 or 8 ohm depending on the 15" L7 setup. Crutchfield does not carry the Kicker L7 in 15" They do have the L5 in 15".
If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms.. Do the Same with VC2+ to VC2-. you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.
