2007 AMP and Sub Install, Who's Done it?

[phildac]

Hey guys,

I got a 2007 Camry SE V6 coming in a few weeks and I've already been thinking about the stereo upgrade. I'm going to keep the stock HU JBL 6disk and probably the factory speakers but I'm going to add a Amp (Kicker XS50) 2 channel and a single 12" Kicker Comp. I have purchased a PAC OEM-2 Line Converter to obtain the RCA outputs for the Amp. I just need to know where to tap into the factory speaker outputs. I'm thinking either at the factory amp under the passenger seat or from the factory rear deck 6X9's. If tapping in at the factory amp, should this be done before the amp or on the amp output, which then I would just tap in at the rear deck 6X9's because it would be the same signal. Who has succesfully done this? Any help on this would be appreciated.

Thanks,
Phil

just tap in at the 6x9's and you should be fine, thats how i did it in my old car with a simlar setup.

Been thinking about this already .... I have 4 RE 8's that simply ROCK .... These little subs actually sound like 10's ... They were built as 8" woofers unlike most 8's that were built as mid bass drivers .... I just can't decide where I am going to go with them yet ... This post should be interesting to watch ...

So chitty, what did you use to obtain your RCA's for the amp and where did you tap in at to get the signal?

I have a 200 Watt Infinity Basslink which I'll have installed within the next two weeks. I won't do it myself cause I know I'll scew it up. The JBL 440 system definitely needs more Bass.

Nice and clean, but I have a tip for you...
Don't install amps upside down. The heatsink should be at the top to help dissipate heat... it's more like an oven when it's on the bottom.

i got one too, i got one alpine type x 12 and 1 pdx 1000 mono with a alpine headunit. i got a dash kit where you can fit a normal din or double din in it.

I am not sure about the regular JBL system, but the navigation unit uses a digital signal from the HU. If the JBL uses the same amp then the LOC will have to be placed after the amplifer.

That's kind of what I've been thinking. It would also be alot easier without having to pull up the seat. Thanks

I have installed many stereos and alarms. I understand the issue with mounting amps upside down. But if you try my set-up you will notice just over one inch of clearance on the top side. This allows the heat to easily escape. With the way I mounted this heat escapes from all sides vs a tradional mount will allow heat to escapes just a few sides. I have done this mounting techinque before and have had no problems as long as you allow heat to rise and escape. I perfer a clean and stealthy mount which allows the amp to stay out of the way from things hitting it or people messing with it.

The install was EASY. Just bring up a power supply with a ignition on source. Mount your amp connect or tap the speaker line level to the factory wiring for the 6x9's. Now hook-up your sub and adjust and enjoy. When I mounted it, I did so where in which it allows for adjustments to be made easily.

Have fun. Its easy...

You do have a nice install, but ieee_raider was correct. Fourier Law of Heat Conduction states that heat will flow from the region of high temperature to the region of low termperature. The use of aluminum heat sinks is to take advantage of the low heat coeficiant of the metal. It allows it to absorb the heat quickly and disipate it quicker than most metals. The fins form a heat convection. Allowing air to circulate around them and remove the heat at a faster rate. The problem with placing the amp upside down is that as the fins radiate the heat out the hot air has no place to go. Hot air naturaly raises forming the convection of circulating air I just refered to. This slows the cooling process of the heat sink and creates a point of equalibrium between the heat sink and the electrical parts. In essance, the amp will just stay at this temperature. Deepending on how hard the amp is used, it may never be a problem. However, if you ever overheat the amp and send it for repair don't expect a warranty to cover it. I work for a electronic facility and this does leave noticable heat patterns on the bottom side of the boards. Look in your manual and I am willing to say that alpine states a proper and improper method of mounting.

Yes, you correct about heat rising. But the heat will rise to the back of the amp (slits cut in back plate) and disipate up to the 1 1/2" gap (between amp and rear deck) then to the rear deck of the car. The rear deck is not flat where in which the only thing touching anything on the back of the amp is the two very sides. The gap is enoungh for my fingers to feel for heat after it has been running for a while and I have felt very little warmth. No clipping of the amp either.

Thanks chitty, I'll let you all know how the install goes, if I ever get my car. Could be here in the next few days or weeks????

Glad to be of assistance.
