Im installing amp in tc to add power to mids and highs. I was wondering if I splice the wires from my amp to the wires that run from the radio to the speakers would that work? I mean the radio is 160 watts and the amp is 200 so would that give me 360 watts? or just run the amp wires to the speaker wires?

 

Pretty certain you can't do that. I personally would just run the amp as it is gonna sound 100 times better than what the stock deck pushes watt wise. But then you'd really make out even better if you replaced the stock speakers if your gonna amp power them....

 

1)the stock deck MIGHT be pushing 17 watts RMS pr channel.....not 40....40 is the MAX which is probably never hit in any stock deck....there isn't any way to combine the power of an amp and the stock deck to the same speakers.....I'm not really sure what wouuld happen, but it wouldn't be good......

2)I'd be careful amping the stock speakers as I'd imagine they would be easy to blow......

3)To run an amp from the stock deck, You'll either need to buy an amp with High Level Inputs (the best route) or buy a line level converter to get RCA outputs for the amps RCA Low Level Input......

 

I was wondering how on earth a stock deck boasted having 160 watts!!!! Any way I got the wireharnes that has the rca outs off eBay so it will pretty much be plug and play (accept attaching speaker wire from amp to speaker wires in car. I am using MB qurat reference 6.5's and diamond hex series 6.5's so they can easily handle 50 watts each. The only other issue is I have a 2 channel rockford 200x2 amp. I planned on just putting to sets of wire to each channel. Is that cool? I figured since deck didnt have separate front and rear pre-outs it wouldnt.

 

If you're wanting to run all the speakers off the amp, then run a set of wires (one +, one -) from each channel to the rear speakers, then from the rear to the front...... be sure not to run the front off one channel and the rear off the other as this will create a sideways soundstage.....


only thing to worry about is the resistance of your speakers... I'm assuming the speakers are 8 ohm (generally, this is what majority of aftermarket speakers are)...wiring them as I said will give you 4 ohms per channel which should be 100 watts per channel....

 

You'll lose the fader controls from the head unit with a two channel amp. But as far as the sound goes, it always will be two channels, so you're not losing any signal.

Personally, I'm still up in the air about whether fader controls are necessary. If I ever change them, it's only by +1 or +2 either way, so it's not much, but just a slight change. And even then, I would do this because the rear speakers are usually larger on a stock stereo system, which isn't the case with the tC's so I probably do it now out of habit. And your speakers will be the same size and probably nearly the same in their output capabilities, so you probably won't really have to worry about it.

And like was mentioned just previously... check the resistance of your aftermarket speakers since the amp is rated xWatts@yOhms, so changing the resistance will cause the amp to significantly increase or decrease the load it sees, which can either be at best a little negligent to your speakers, at worst, bad to your amp.

 

sounds like what I needed to know , now I just gotta install all the freakin wiring through the center console and along the side of the car (no biggy right? yea right) If it works out I will post photos of car since I have alot of adds and will be runnin a 15" JL audio sub as well... Not a huge kickin system but only a 15" sub gets the bass I like (doesnt have to blow my eardrums out of my head I just really like the low frequency bass that 10's cant give.

 

JL 15"....I'm guessing it's a W3??? if so, that is gonna pound (as long as there is ~500watts at it!!!)...... my 2 12w3's with 632RMS on them is hitting a 143.6......which isn't Mega loud.....but considered pounding......

make sure you run the RCA cables apart from your power and remote wires....otherwise, you run a chance of noise interference.....

 

Dang I forgot about that, anyway to run power and rca's down the same side of the car without noise interference? Didnt really wanna take both sides of my car apart.

 

The car is soooooo simple to take apart and put back together!!!! It takes all of about 5 minutes to run the wire down the opposite side if you already have the dash apart!!!

just take the extra time and do it correctly, you'l be happy in the end that you did!!!
