Amp issues I have the american legacy 2488d 2000 watt mono block amp and 2 10' subwoofers in a bandpass box. the 10's are 1 pioneer premiere and sony x-plod 1100watt. I have also ordered 2 DVC 10's just in case. I want to know how i should wire this to achieve the most bass. It's installed in a '94 Ford explorer.

I myself would run a parallel bridged ciruit. basically run the speaker wires one positive on the right speaker side and one negative on the left side.

thanks

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.

I need to know the size of external fuses for a american legacy amp 2000 watt 2 channel 1990


25 to 30 amp fuses will work great, anything lower could possibly blow a fuse when a good bass note hits even if there is nothing wrong with the amp. Hope this helps.

I have a 2500 watt legacy ice amp and im tryin to hook it up to two 900 watt rms soundstreams daul voice coils whats the best way


If you amp is 1 ohm stable you can run + to +, - to - on each voice coil. Wire them into the box. Run +'s to +'s on amp, - to - on amp

Other wise. If it is a 2 ohm stable amp, you run two 4 ohm dual voice coils to the amp + -, + -

If the subwoofers are 2 ohm, run + - on only one voice coil to the box for each and run + -, +- for 2 ohm load on amp or + - bridged for 1 ohm load.

I hope that makes sense.

I have 2 dvc 4 ohm alpine type r 15's and 2 svc american bass


Hi mate very nice amp you got there here is the specs for it



Model: MA Audio HK401SX
Hard Kore Series 1800 Watt 1 Channel High Performance Class X Car Amplifier
1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS @ 1 Ohm Mono
1 x 650W RMS @ 2 Ohm Mono
1 x 500W RMS @ 4 Ohm Mono
Fully Unregulated MOSFET Power Supply
2 Ohm Stable @ Mono
1 Ohm Stable @ Mono
0.5 Ohm Stable @ Mono

if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.

The fuse from the amp to the battery keeps burning


maybe it cannot accomodate too much power running on it...too much current, try another fuse with higher ampere rates

What size fuse do i need for amp


start with a 50, may need to increase it if you are not using a large capacitor.
600 watts = 12x
x= 600 watts / 12 volts
x = 50 amps

Optimum sound performance needed


1) legacy products are highly overrated and i have never seen one put out the power it claims
2) if you are running the amp bridged, you need to match the impedance of the speakers to the amps highest output impedance, otherwise your system will not sound all that great...

what size fuse or fuses does your amp use? what size wire did you install with (power and ground)? did you connect direct to battery or did you connect to a fuse block or similar? did you use a stiffening capacitor? does it sound like it is clipping when you turn it up or is it just distorted? what kind of box are you using for the speakers (ported, vented, sealed, bandpass)?

if you give me the model number of your speakers and your amplifier i can probably help you more, but with the information you have provided, this is all i can offer..

hope it helps,
trin
