hello . I have this amp 1200W Max Sycho Sound Mono Amp. Its rating are **400 Watts RMS at 4 Ohm** **600 Watts RMS at 2 Ohm** **1200 Watts Max at 2 Ohm** **I got this wiring from knu koncepts klm 4 gauge amp kit with** **80a agu fuse.** **I have a few question** **My first is what difference does the fuse make Is the fuse i have in the amp kit ok for the amp . The car is a 93 volvo 850** **My second is** **What ohm subs should I get for that amp . Can I use A 2 ohm amp with 2 ohm subs** **I was thinking about getting the 07dcvr12 2 ohmOr the kicker s12l5 2 ohm.** **Thanks for helping me.** **Im a newb on car electronics. its funny i can fix a engine but electronics . There is no way i can fiqure anything out** ---

1. no-name amp, it’ll work ok for general usage, but not that great. 2. ALWAYS run a fuse within 18" of the battery even if the amp itself has a fuse; it can save you from starting the entire car on fire if you develop a short. 3. as for what subs to run; you need a 2 ohm load minimum; thus if you have 2 2-ohm subs, you can not use them (you can only get a 4 ohm or 1 ohm load with 2 2-ohm subs). Look up how to wire subs; Parallel Vs Series. You will need 2 4-ohm subs if you want to run a pair of subs with that amp @ 2 ohms. If you’re only running 1 sub, then that either needs to either be a 2 ohm SVC (single voice coil) or 4 ohm DVC (Dual voice coil); look at the subs specs to find out. ---

so why cant he run that at 4 ohm? and if he had two 2 ohm subs he could run them i stereo. ---

according to rockford with one dvc 2ohm l5 and that amp you can get a 1ohm which wont work with your amp or a 4ohm which will but wont provide full amplifier output, youd be better off with 2 2ohm subs so your amp can achieve max output ---

The more you pay for an amp the less thd it should have. thd is what kills subs as well as electronic parts. and dont forget if your looking at amps mono means one… one hook up. any questions about this you can call darylls car audio for any help over the phone. ---

[quote=“sickmach,post:18,topic:38170"”] and dont forget if your looking at amps mono means one… one hook up. [/quote] Mono means a mono signal output, as in not a left/right stereo output. Most monoblock amps will have multiple “hook ups” as you call if for different sub/wiring configurations. You can run a single sub off a monoblock amp, or 16+ subs off a monoblock amp, as long as the load at the amp is correct.
