Alpine R-Type components

I have a pair of Alpine SPR-176A's (6.5") component set to install in my 2002 Civic Type-R for the front, along with a pair of SPR-174A co-ax 2way's for the rear. There is no sub or amp as I am just a beginner trying to improve the factory fitted kit. The head unit is a Sony CDX-F7500 (new) with 50W x 4 at 4 ohms, impedence 4-8ohms.

Can anyone tell me if the H/U is a good enough match for the speakers, or if I have missed something out. I have been trying to find some information to determine if the speaker powers suit the H/U, since the 176's are 50W RMS and the rears are only 40W RMS, will they blow on high volumes?

As you can tell I am a novice, and will be humbled by any advice you can give me. I would also like to set the HPF and LPF on the H/U so it is optimised for the speakers, but again don't know much more than I have typed?

The speaker specs are as follows;

SPR176A's

• 6.5"
• 200W max 50W RMS
• 40Hz - 30kHz
• 86dB/W(1m)
• 4 ohms

SPR174A's

• 6.5"
• 160W max 40W RMS
• 45Hz - 30kHz
• 87dB/W(1m)
• 4 ohms

You will never get those speakers to sound right unless you amp them with at least 50 watts rms.  Your mids wont have the impact like they should, and they will definately dissapoint you if you keep them running off the amp.  

And  definately in the future look into getting a sub, as you will be missing out on lots off bass.

Thanks for the advice so far. I didn't realise the H/U only output 23w RMS, so is there a rule of thumb for RMS power, should it match the speakers or be lower than the speaker handling power?

I would like to amp up the speakers, when I have some more $'s. Should I ignore the HPF & LPF settings on the H/U until I have an amp?

Also does anyone know if the supplied speaker wire would be an improvement over the Honda OE?

Thanks again

The rule of thumb is that the amplifier should drive the speakers without overpowering them.  At this point, do as DYohn suggested and do a nice install on what you have.  Upgrades will come as you can afford it.

It doesn't hurt to fiddle with the crossover settings on the head unit to tweak the sound to its best.  Look for the higher freqs on the front and lower in the rear.  As you test things out, you may very well find that full-range sounds best all around.

The speaker wire will make no difference.  In this case, go with the original for ease of installation.

I personally have used type-r 6.5" woofers in a sealed box, powerd with 200 wrms getting sub frequencies, and they don't skip a beat!!  It is better to overpower you speakers then to under power them.

When matching an amp for these speakers get a minimum of 50 watts rms per channel.  10 billion sony rms may do.
