Need help with installing aftermarket amp and subwoofer

I need to have more info about how you installed it, did you use rca wires from the radio to the amp.? Make sure the sub setting on radio is turned on. Make sure rca wire are in the input connection and not output, also check you connection from radio that they're in rite place. I really need more info about the map of your wireing

in most case the amp is just to boost subwoofer sound cause usually it damage peak speaker unless you combine it with 6.9 speakers.if you bypass the amp you wil need output cables and fuse to connect them with amp

The amp is blown in the trunk, same with mine. I had it replaced with an alpine aftermarket amp and it works fine now.

you can buy a radio wiring harness at a discount store or an aut parts store, it comes with directions. Hope this helps Tim

You need to:

Wire the low level output from the new 'deck' into the stock amp input.

Or replace the stock amp with an aftermarket amp.

Hi, First off do you have an aftermarket radio? If you do, does your car also have an aftermarket amp and/or subwoofer? If this is the case, you need to get a power capacitor. This is basically a small battery mainly used to supply the extra power to the speakers and/or amps during the loud thumps so that it doesn't drain from the car's other functions. Hope this helped.

no problem with replacing all speakers with ones that are compatable wth you new amp .. and that means the the speaker impedance has to be wtihin the range of what the amp can drive (like 4 ohm, 8 ohm, 16 ohm) .... the subwoofer needs inputs from both left and right channels .. it also needs its own amplifier and low pass filter .. this all may be built into your after market amplifier .. if so you will have an output marked sub (that will directly drive the subwoofer) .. or you may have a low level outdput marked sub that goes to your subwoofer amplifier if it has one .. .. sometimes the woofer has its own built in amplifier and filter .. it then just needs power and inputs from each channel .. since you are running 500 watt speakers, they likely already have a subwoofer component .. (speakers that extend down to 20 hz or lower .) if so, you may not need an additional sub-woofer .. just make sure all the speakers are phased correctly .. (wired to work together not fighting each other ..) .... an amplifier capable of driving 500 watt speakers can draw peak currents that are very high .. so power wiring would have to be very heavy and preferably go directly to the battery with an inline fuse right at the battery ..

go to crutchfield.com they have install videos

very carefully, should have a set of tools with the manual

The only way to Correctly do this is to Run an External Amp for your Subs. If you continuously run the Subs off of the Factory Amp It will Ruin the Subs and the Amp Eventually. This way you can still Connect the Rear speakers as they need to be. Please Rate my solution, I need all the Help that I can Get! Thanks!
