I have a 1997 isuzu. I bought 2 alpha sonik 10" subs and a california profile 600 watt amp. It played the radio fine till I hooked up my amp to the cassette player. we checked the fuse in the fuse box holder located behind the cassette player and it was blown. So I replaced it and that didnt make a difference so since im getting a new cd player in the mail we by passed it by cuttting the fuse box off and re splicing it. After doing that the Cassette player turned on but it plays no radio. Its stuck in am and the casstte player is re winding for some odd reason. I look at the attena wire the goes to the attenana on the outside of the car and it looked fine. I stuck now and was wondering if anyone knew a thing or too about this so im hope someone comes through. Thanks - Zach

For a sub to play it needs wiring from sub to amp and the amp needs power from battery and amp needs signal from radio and amp needs to be grounded oh and it needs a remote signal from the radio as well and if your radio is stock and has no RCA outputs you need a LOC which will connect to you speakers with wire and to your amp with RCAs
that is very strange but it could be that when you put the cd in the radio it maybe sending out a quick shot of amplified power I would try disconecting the subs put in a cd let it play a little then plug the subs in while the cd is playing and see if they work if this works you may to get a new radio or put in a switch to turn the subs off or some type of momentary circuit breaker I'm just trying to help I never saw anything like that before good luck........
The Alpine has two tigger wires when it turns on. One is an AMP TURN ON wire (blue/white) and a PWR ANT wire (blue) and that wire only comes on when using the radio or an optional HD radio unit ... When it was installed/connected . someone hooked your amp turn on wires for your "full range amps" to the PWR ANT wire. And the sub amp trigger is either hooked correctly to the AMP TURN ON WIRE or somewhere else, it probably shouldn't be... Check it. Amp triggers should all be to the blue/white wire from your alpine. Warning: Alpine trigger wires, are very easy to mess up they supply a very limited amount of power.
You may have Power antenna and amp remote turn on wires switched. Your system may be looking for turn on signal from radio and only gets it when am or fm is on because power antenna wire is hooked up instead of amp turn on signal.
