Well I have just purchased rockford fosgate 6x8's for the doors of my lightning. I also bought some 6.5 rockford components model P162S that I am planning to install in q-logic kickpanels. I was wondering if I need an amp to power these speaker, or if they would attatch to my existing amp. Currenty I have two 8 in. kicker solo baric's hooked to a memphis amp model 16-ST500D. I know next to nothing about car audio and didnt know if I should purchase an addtional amp, or if the existing is fine to run all of this. Also, if I do need another amp, which rockford amp would be good for these speakers, I get a great discount on rockford so thats why I got all rockford products. Thanks for the replies.

If you're going to be putting in 6.5s, take those 6x8s, it'll sound better and be less complicated in the long run for you.

 

Id also kinda go with what Kujio said, in a regular cab, one set of components or a set of coaxials is usually all your going to need, and usually all youll wants (its all I have in my ext. cab) UNLESS you really like very 'thick' (not sure how else you put it) type sounding sound (for your mids and highs anyway). Those extra set of coaxials will just mess with your soundstage and imaging a tad.

So if it was me, Id sell the coaxials and just use the comps. Plus, youll only hafta buy a 2 channel amp.

 

I seem to be hearing from everyone that just putting the components in the doors is the way to go. Guess this means the 6x8's are a waste. I'll have to pick out a good amp and put those components in the doors. Would the 6x8's help anything if i put them in the rear, next to the sub box? Also, what kind of amp should i be looking for, watt wise and what not? Thanks again for the help.

What amp to get is based on the rms specs of the speakers.If the speakers are 75 watts rms look for an amp with a sim rms.

 

If you can want you can stick them in the back (if you like the rear fill sound) but again, they arent really needed and will just mess with the sound.

 

If your headunit doesn't support time alignment you might gain better imaging and some more midbass response glassing then into your kick panels.

 

Thanks for the help guys. So if the speakers have 75 rms a peice, and I use 2, I want a 150 watt rms amp? That seems to make sense to me, but can an amp have too much power like an amp with 500 watt rms? Thanks again for all the help.

From his first post I dont think he's to the point of getting into the time alighnment and 'glassed k-panels and that stuff just yet

If your comps are 75 wrms-Id look for a 2 channel amp rated at around 50-100 or so wrms per channel. Youll see the amp rated something like 2x75 watts or something.
Id watch to make sure those numbers are rated at 4 ohm too, which most of the advertised numbers are.

When you see something that says its a 500 wrms amp (assuming its a 2 channel) that probably the rated power bridged. which would be something like 125 wrms per channel give or take some. Which, unless you really know what your doing, I probably wouldnt go that high.

 

Thanks for the help everyone. I think I am starting to understand more about car audio. So I'll find a good amp and find a good installer to have my components and amp put in. Thanks again for all the help, glad there is a place where people are helpful and dont criticize you for not knowing things like most forums. Im sure I'll be back with more questions.
