Thread: Need help with subs

I got these subs for free and i would like to hook them up to the stock headunit in my gtp. Its a 2002 and has the bose system. If someone could explain to me the easiest way to hook these up that'd be great. I would really appreciate it. Here are some pictures. The owner before maybe had some hooked up? I think this is and amp of some kinda in the first picture. There are some others. Thanks.

The Wheelen CSP660 is a strobe power supply. Usually only used for Emergency vehicles. Police, Fire, Rescue etc. It is not an amp. Was your car a police vehicle???

Yea i realized it was a strobe supply after I posted this haha. Says strobe supply.... and idk I still have the strobes they are in my headlights and tailights. They are blue but i dont think it was a police vehicle maybe volunteer firefighter?

Anyways from further reading i realize i need a line output converter how should i go about connecting this and is it safe?

For right now i am going to keep my factory bose headunit. Will i be able to tell that the subs are there? So i hook up line converter to speaker wires. I can do this to the rear speakers in my trunk, the wires that go directly to my rear 6x9 speakers? splice the wires and then conect rca's to my sub amp?

X2^^^, hook the line converter into a speaker wire from the radio not from the amp.

How do i know what wire is from the radio to the speaker ? Do i have to take out the head unit and look or can i look to see which line is coming from the amp and splice the other?

If someone knows how to hook this up itd be great

Ok, thanks. Do i need another way to get power to them?

Car audio guy at best buy recomended this..

Scosche - 2-Channel Adjustable Line-Out Converter - Clear - LOC80

And then said to hook it up on the lines from bose amp to the rear speakers..
You guys are saying to splice before the amp is there a reason for this?

With the line converter, the sound is going to differ in volume as the wattage is going to be different, so eliminating on variable makes the equation easier. The signal will be purer straight from the head unit, which will lead to better sound quality.

The sub amp I assume has a low pass filter.
if not then you need a way to block the highs as the signal your getting is full range.

Thanks guys. Do you know how i am gonna be able to get power to them? Would i be able to get power from that strobe power supply some how instead of running all new wire?

i install those strobe packs in police cars all day be carefull they will light you up

I wont touch it then

No, you will need to run a new power wire. Anywhere between 4 and 8 gauge, depending on the wattage of your amp. The lines to the strobe supply look too small.

Is there a special end that i need for it to compatible for my amp or any 4 or 8 guage will work?

Compatible? The sub amp will have nothing to do with the factory amp. Just run a 4 or 8 gauge power line from your battery to the sub amp. Find a grounding point in the trunk, and run the RcAs from the in-line to the sub amp.

Ok sounds good. Thanks
