Default Dboy, Need Help Mounting Speakers

I currently have a pair of Infinity 5.25" speakers mounted on my kick panels. What I would rather have mounted there are my Rockford Fosgate 6.5" FRC1206's because they have much fuller sound than the Infinitys.

The problem is they are too deep and the basket hits the metal frame before they are seated on the kick panels.

Do you have any suggestions for a mounting adapter that will clear the frame, not get in the way of the clutch and dimmer switch and not look like hell?

TIA

It's really very easy, but it requires some minor trimming of the lip around the body mount pocket. It only takes about ten minutes per side with an angle grinder. Place heavy towels all around the area and under the dash to catch the slag so it won't melt your dash panels or carpet.

Here are some pics to show what has to be trimmed out to make room for 6.5" speakers.

DB, aren't there spacers available for 6.5 in speakers. I vaugly remember seeing a black 1/2" round spacer placed just behind the speaker somewhere, that might help with the basket clearence issue.

Yes, but they push the speaker out a little over .5", maybe closer to .75", and that would interfere with the space for the clutch pedal. There is already limited space down in that foot well, and a spacer would eat a lot of that up.

In my interior re-do, I used Polk Audio 6 1/2 component speakers with seperate tweeters and crossovers. They fit with no trimming. The crossovers are behind the seats in the quarter panels, and the tweeters mounted there also, below head level. These speakers will rock your world even if you have side pipes. Outstanding sound performance. Couple that with a Clarion thin line sub-woofer and it sounds like the band is in the car with you. I only have a small Sony 4 ch. amp too. Tank

Thanks Durango_boy. Looks like I need to invest in either a die grinder or a cut-off wheel if I'm going to fit them in there.

Your kick panel looks like it has a raised surface compared to mine. It's flat as a pancake. That probably helps some with clearance too.

I'll be pulling the seats and carpet over the wointer to install Reflectix so that will be the time to take a hard look at it and decide if I really want them in there that badly.

I already have a 10" Kenwood sub, the Infinitys, a pair of Pioneer 4x6's in the dash, a Kenwood four channel amp bridged for the sub and a Rockford Fosgate 4 channel amp driving the front 4 speakers. The head unit is a Jensen unit with usb, SD, iPOD, satellite and Aux inputs, cd player, front, rear and sub out.

I dumped all my favorites onto a 1GB SD card and flip through it all day long. No fumbling with CDs for me.

I relocated the system from the '02 vert I traded in for the '72 coupe and in the '02 I had the RF speakers installed. That's why I want them in the '72 is because they sounded so much better. It's probably more a function of the size rather than the make of the speaker.

The fit of the speaker in the custom kick panel is indeed helped by the panel itself, but when I first made the cuts for clearance I installed the largest magnet speaker I could find into a stock kick panel with a speaker hole cut out. It fit snug but went flush and mounted perfectly. I usually back the kick panels with a piece of hardboard cut to the shape of the kick panel to help with rigidity.

Also, and you'll have to trust me on this...your system will sound a lot better with just the kick panel speakers and NO dash speakers. In fact, having dash speakers AND kick panels speakers will hurt the sound.

The kick panels are a much better location. Tweeters are ok in the dash, but mids sound far better being lower.

Your amp configuration is perfect. Bridge channels 3 and 4 for the sub, and run the TWO front kick panel speakers from channels 1 and 2.

Disconnect the dash speakers and you will be pleasantly surprised with hos good just the two kick panel speakers sound. Provided they are coaxial obviously.

Yoyu think even the 5.25 inch Infinitys will sound good? They do have aimable tweeters. I just think all the lows and mids will have to come from the sub.

It won't hurt to try. I may as well bridge the front and rear channels on the Rockford Fosgate and direct all the power to the Infinitys.

I would really like to try to talk you into a pair of 6.5" speakers for the kicks for the mid bass that 5.25" speakers just don't offer. The sub will offer plenty of backup but things do tend to get a bit tinny with Infinities.

Install the Fosgate speakers in the kicks instead of the Infinities and I think you'll be very happy, even without the 4x6" speakers.

Do you have pics of your tweeter placement? Also where did you mount your amp? I'm about to get into the same stuff. I have a pile of components in the shop and I'm ready to go

Alright, I figured out a way to install the Rockfords without cutting or using a spacer.

The normal installation calls for the plastic trim ring to go on top of the speaker. I put the speaker on top of the ring and it provided just enough clearance while taking up the same amount of space as normal.

It's so good to have bass!

George - Did you ever figure out why your amp was in protect mode?

I'll get them up as soon as I can.

Another question...can a 4 channel amp be bridged to 2 channel stereo or will it only produce mono?

Theroretically, I should be able to run one speaker off the rear channels by connecting the speaker to the left positive and right negative and then do the opposite for the front channels. Or am I going to fry the amp, speakers or both?

Bridging only works if the amp is set up for it. Some older amps are not capable of bridging. Most new ones are. The only reason you would want to do this is for high powered handling like subwoofers.

This will be your best wiring option. Bridge channels 3 and 4 to power the sub...assuming it's capable of bridging. Then, run the front two speakers off of channels 1 and 2, one channel per speaker.

This will give you powered front speakers, and a single powered sub, all form one 4 channel amp.

Yes my amp is capable of bridging but I don't need it forthe sub. My sub has it's own 2 channel amp bridged to 1000 watts mono.

I'll just leave the RF speakers on the front channels and not use the rear channels. That gives me 50 watts per channel.

Thanks Durango_boy for all your help. Sometimes all it takes is a little insight and some moral support to get a project off the ground.
