I have 2 kicker tweets with crossover running off the front channels of the alpine along with the alpine 6 by 9.. Is this safe or is there a better way to run my kicker tweeters.

As long as the crossover keeps the frequency going to the tweeters within a safe range (I'd say about 500hz+, read the box or look it up by model number) they should be just fine. That is what the crossover is for.

I have a 8 0 4 phonix gold amp and two 12s i blew the 12s and i bought some but they are 4 ohm how should i wire them?


You will have to wire each sub to an individual channel. you cannot bridge the amp, because it is not stable at 2 ohms. You could bridge it if you wire the subs in series, but you will get more power by committing each sub to an individual channel.

Can i bridge rsd60.1 ser#069243867003


Negative a any amp that is 60.1 or 1500.1 whatever it is .1 is a mono amp and needs no bridging. Some mono amps are set up like a 2 channel but they aren't bridgable they just add more options for wiring each individual sub to the amp...

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

I have 2 6x9 speakers up front 4 6 1/2 3-ways


Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

Amplifier displays "CUR"


Hello anwbrown,

The "CUR" display means that the amp is drawing excessive current and the protection circuit is activating. Too low impedance or shorted speakers will cause the amp to draw excessive current.

The Alpine V12 is a Class D mono amp with only one set of speaker outputs. All versions, M301, M501, and M1001 are only stable to 2ohms. Assuming that all 6 of your connected subwoofers and speakers are 4ohm and they're all connected in parallel, the amp sees a .67 ohm load, far below it's rated impedance.

When brand new, the amp could probably operate at low to moderate volume levels without drawing excessive current. But as electronic components age, their tolerances change and they become less able to withstand excessive current or mismatched impedances.

I'd get a 4-channel amp and drive the 4" speakers off the front channels and the 6X9's off the rear channels. And just power the subs off the V12 making sure that they are connected to show a minimum load of 2ohms.

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.

Amp problem, need help!!!


Sounds like one of two problems: either your subs are beginning or have gone bad, or you amp is going bad. What size power and ground wire are you using? You should be using at least a 4 gauge for both. Also what impedence are you running with the amp, ie; 4ohm mono, 2ohms stereo, etc?

Please help


That depends on what impedence the subs are. If they are 4 ohms each then just parallel them to the amp + to + and - to - on both of them that will give you a 2 ohm mono load which is fine for that amp.

Sub Wiring


if you wire the subs in parallel you would achieve 2 ohms which would theritically double your rms, sadly this isn't the case what with wire resistance and such you might get around 270 rms still not that bad. to wire in parellel you run a positive off the amp to the positive on one sub then run a wire from the first subs negative to the second subs positive the run from the second subs negative to the amps negative and bam 2 ohms but be warned this will put more stress on your amp and cause it to heat up faster. peace bro and best of luck
