Protect Light On Amp Being Weird


Could try switching right and left subs. If the problem moves to the other side pull the wiring and redo.
Then if the wiring is ok check the sub.

If i have a 4 channel 2000 watt amp, can i use 1600 watt wires if i only have 2 subs hooked up to it?


Yes, you will be fine. 4 gauge power wire is sufficient for a couple of reasons, the primary one being that most of the companies that are boasting 2000 watts for a 4 channel amp are off brand "web-retail only" companies, and they severely over rate the power output of their amplifiers. Secondly the supposed 2000 watts is peak power and not rms power. Peak power means how much power that amp can put out during absolue climax of the music or during a tone burst. RMS power is how much that amp will put out continously to your speakers or in this case, your subs. If you look at the spec sheet of that amp, in all actuallity you're probably only getting 200-300 watts rms even bridged.

On a side note, if you really want to push your subs hard, you might want to consider getting a mono block or "class d" amplifier and use that 4 channel amp to push your surround speakers. Class d/mono block amps are specifically designed to push subwoofers and will give you the most efficient power out and the best heat dissipation to withstand the output required to drive subwoofers. You'll get better bass and also more adjustability to tweak the sound levels coming out of your subs. Hope that helps.

How i wire my sub to my jbl gto301-1iiamp with 2 Hifonics HFi12D4


If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
+ -
+ - + -

If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

I just need to know the best way to hook my amp and subs together. i like a lot of bass. i just bought the subs and yhey dont really sound any diffrent. should i get a new amp.


Hello hembreegerry,

If you like a lot of bass, you definitely need to consider another amp. The SP2X-300 is only rated at 170 watts RMS into 4 ohms mono. That would barely be enough to power one small sub. You do not specify what brand and model your subs are, their impedance, or their power handling capacity. But for any subs, your best power solution is to add together the individual RMS power handling capacity and select a monoblock amp that provides close to the maximum at the impedance they will be wired to present. For example, if your subs are 4 ohms and have a maximum RMS of 250 watts, you would want an amp that outputs abour 500 watts into 2 ohms (2 4 ohm subs wired in parallel = 2 ohm load). An ideal amp in that example would be the Alpine MRP-M500 which outputs 500 watts RMS into 2 ohms.

Hope this helps.

Alpine pdx 1.000 keeps cutting out


You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


Hello juan_penaloz,

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.

Installing two amps


No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)

Building Competition stereo's is a big hobby of mine.

that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.
